The adverse effects of urbanized areas’ growth might be mitigated by the multiple ecosystem services that urban green infrastructure provides. However, the design and composition of such infrastructure is still a hotly debated issue, mainly considering the challenges associated with the use of exotic plant species. To assess if there is a clear association between the species’ origin and ecosystem services or ecosystem disservices, an in-depth systematic literature review was carried out based on a bibliometric approach to assess the panorama of the scientific perspective. Based on the results, a detailed analysis was performed for the urban green infrastructure of five European Mediterranean cities, where management and expansion of the urban green infrastructure might act as tools to mitigate climate change and biodiversity loss. Urban green infrastructure benefits to urban areas and its composition must consider the balance between services and disservices provided by plant species. Data analysis shows that disservices are not exclusively related to exotic species, revealing that plant species selection based on their origin represents a biased approach, as it often disregards the higher capacity of some exotic species to thrive under continuous pressure and disturbance, along with relevant and highly valued cultural services provided. Since exotic species are commonly used, ecosystems formed can be seen as experiments to support decisions, allowing new approaches to planning, designing, and maintaining urban green infrastructure.

Urban parks, as major components of green infrastructure, have contributed to natural landscape preservation, ecosystem service provision, residents’ physical and mental health enhancement, and social cohesion intensification, under the emphasis on the need for sustainable urban development. However, urban parks have been insufficiently and inappropriately created in the process of the urban space expansion and population density increase, necessitating their equitable distribution and access. This study aimed to analyze the distribution characteristics of a total of 354 urban parks in Seoul, South Korea, utilizing the estimates of floating population derived from big data and the urban park catchment areas, in the context of the 15-minute city. Its 25 districts were classified into the following four types based on the relationship between the area and the population ratios for the 600 m and 900 m catchment areas: Type 1 parks were equitably distributed with well-matched supply and demand; Type 2 parks had an uneven distribution due to insufficient supply and excessive demand; Type 3 parks were inadequately distributed with both supply and demand below average; and Type 4 parks had a mismatch between sufficient supply and unfulfilled demand. This study suggested strategies to improve the spatial equity of urban parks for each type, including qualitative improvement, quantitative increase, redistribution, and accessibility optimization tactics.

Located in the Yangtze River Delta region, Jiangsu Province has become the major grain production area of China and plays an important role in ensuring national food security. With rapid economic development and urbanization, the amount of cultivated land has decreased, which greatly affects food security. Based on the statistical data of grain production in Jiangsu Province since 2000 and the remote sensing data of 2000, 2010, and 2020, this paper used the stochastic frontier production function to calculate the output elasticity of various factors and the technical efficiency of grain production. The agglomeration effect of food production was investigated by using spatial correlation analysis. Finally, regression analysis was applied to examine the impact of land use change on grain yield and the technical efficiency of production. The results show that the grain-sown area is the decisive factor for the increase in grain output in Jiangsu Province. The technical efficiency of grain production in the province has been maintained at a relatively high level since 2000, showing a fluctuating upward trend, and the efficiency value in southern Jiangsu Province is greater than that in central and northern Jiangsu. The analysis of the spatial distribution characteristics of grain production technical efficiency shows that grain production has an agglomeration effect. The regression results showed that the complexity of land use and the density of the cultivated land patch were negatively correlated with grain yield and grain production technical efficiency, while the location of cultivated land was positively correlated with grain yield and grain production technical efficiency. The conclusion of this paper has important policy significance for promoting food production and ensuring food security.

Urban sprawl has become a notable feature in China. Previous studies have found that railway development has a significant effect on urban sprawl. However, the detailed mechanisms of how railways affect urban sprawl have not been studied in depth. Furthermore, China’s railway system has already formed a network. The network status of cities within the railway network may affect urban sprawl, but few studies have examined this factor. In this context, to explore the effects of railway networks on urban sprawl and the mechanisms of these effects, this study applied the social network analysis (SNA) method to measure the indicators of railway network characteristics and conducted panel model regression with the above indicators using the data from 26 cities from 2011 to 2019 in the Yangtze River Delta (YRD) in China. The main conclusions are as follows: (1) Railway network construction has a significantly positive impact on urban sprawl through the network agglomeration and diffusion mechanisms. (2) The network agglomeration mechanism improves the location condition of the central cities on the railway network, which encourages urban sprawl as an agglomeration pattern. (3) The network diffusion mechanism enhances the integration of the peripheral cities with the central city on the railway network, which encourages urban sprawl as a diffusion pattern. The network diffusion mechanism is heterogeneous in metropolitan areas (MAs) for the different levels of central city agglomeration. The findings provide a reference for railway construction and urban planning.

The non-grain production rate (NGPR) of cropland is a grave threat to global grain and food supply, and has been a hot issue across the world. However, few scholars explored the impacts of the NGPRs of different cropland types, such as those of paddy land and irrigated land in the same region. Thus, according to the third land survey data, this research first estimated the NGPRs of cropland, paddy land, irrigated land, and dry land at different scales in Shandong Province, China in 2019. Then, their spatial characteristics at a county scale were identified by combining the standard deviation ellipse model and spatial autocorrelation analysis. Finally, the potential driving factors of the NGPR of cropland were explored with the geographical weight regression model. Results are as follows: (1) The NGPR of cropland is at relatively lower level in Shandong Province and is dominated by that of irrigated land, and the NGPR of dry land is higher than those of other cropland types; (2) Significant regional differences exist in the NGPR of cropland, with profound severity in the southeast and much lower in the northwest; (3) At the provincial scale, the total power of agricultural machinery per capita and utilization degree of cropland factors can relieve the NGPR of cropland in nearly the entire research area. The proportion of GDP of the primary industry in GDP, urban population rate, and DEM are the main obstacles for NGPR decrease. At the county scale, the influences of driving factors varied across regions. This research can provide targeted and regional differentiated references for policy improvement and NGPR management.
耕地非谷物生产率（NGPR）严重威胁着全球谷物和粮食供应，一直是世界范围内的热点问题。然而，很少有学者探讨不同耕地类型（如同一地区的水田和灌溉地）的非粮食生产率的影响。因此，本研究根据第三次土地调查数据，首先估算了 2019 年中国山东省不同尺度的耕地、水田、灌溉地和旱地的 NGPRs。然后，结合标准偏差椭圆模型和空间自相关分析，确定了它们在县域尺度上的空间特征。最后，利用地理权重回归模型探讨了耕地NGPR的潜在驱动因素。结果如下(1）山东省耕地净收益率水平相对较低，以灌溉耕地净收益率为主，旱地净收益率高于其他耕地类型；（2）耕地净收益率存在明显的区域差异，东南部严重，西北部较低；(3) 在省域范围内，人均农业机械总动力和耕地要素利用率几乎可以缓解整个研究区的耕地 NGPR。第一产业 GDP 占 GDP 的比重、城镇人口比率和 DEM 是 NGPR 下降的主要障碍。在县域尺度上，不同地区的驱动因素影响各不相同。本研究可为政策改进和 NGPR 管理提供有针对性的区域差异化参考。

Local governments in China have decision-making authority over urban land use, and their level of environmental attention influences the green use of urban land. However, the impact of local government environmental attention on urban land green use efficiency and its mechanisms remain unclear. This study utilizes panel data from 284 cities from 2003 to 2020 in China and employs fixed effects models and mediation analysis to investigate the pathways through which local government environmental attention affects urban land green use efficiency. The main results are as follows: (1) Through a series of significance tests, local government environmental attention has a significant positive influence on urban land green use efficiency in cities. (2) Further research suggests that both the quantity and quality of industrial structure upgrading act as intermediaries between local government environmental attention and urban land green use efficiency, while the rationalization of industrial structure plays a partial masking role rather than acting as an intermediary. (3) Furthermore, a regional heterogeneity analysis indicates that the impact of local government environmental attention on urban land green use efficiency is significant in the central region but not in the eastern and western regions. Based on these research findings, this study provides valuable policy insights aimed at contributing to green land use and sustainable development in Chinese cities.

We assessed the effectiveness of land optimization for controlling non-point source (NPS) pollution by combining a multi-objective dynamic planning approach with the application of the Land Use and its Effects at Small regional extents model and the Soil and Water Assessment Tool. The combined modeling approach showed substantial ability to reduce NPS pollution in Shitoukoumen Reservoir, Changchun City, China, reducing the annual total loads of nitrogen and phosphorus in the study area by 8.7 and 10.12%, respectively. The total nitrogen load decreased significantly and stabilized at less than 8 kg/hm2 from a peak level of over 15 kg/hm2. Higher total phosphorus loads before land use optimization were concentrated in the central parts of the study area, with the highest values exceeding 2.3 kg/hm2, and tended to spread outward but resolved at 1.5 kg/hm2 after optimization. The results showed that from a macro-perspective, optimization of the spatial distribution and quantitative composition of land use can effectively control NPS pollution. The study also demonstrates the potential effectiveness of the coupled multi-model methodology for mitigating NPS in the future.

Cybersecurity risk management in land administration systems is crucial for maintaining the integrity of spatial cadastral data, which faces increasing threats owing to the digital transformation of LAS. This research validates the findings of this preliminary step in the form of a cyber risk management methodology that combines BPMN 2.0 with model business processes implemented by a compliance-based approach using EBIOS Risk Manager. A practical case of land parcel subdivision in Indonesia is analysed to serve as a proof of concept for our proposed methodology. Vulnerabilities are identified and are characterised by a concentration of manual tasks and the absence of systematic controls, resulting in significant risks to data integrity. These findings underscore the urgent need for a proactive approach to strengthen the cyber resilience of LAS. This study attempts to develop a fit-for-purpose reference methodology for cyber risk management specifically tailored to LAS to identify and treat vulnerabilities, threats, risks, and impacts.

With the intensification of the effects of climate change, the urgent need to address their drivers, especially greenhouse gas emissions, has become essential. In this context, forests offer a robust solution, with their potential to store and mitigate carbon emissions. However, striking a balance is critical given the significant economic contribution of the forestry and wood-based industries, which account for about 5% of Romania’s GDP and employ 6% (around 300 thousand) of its active workforce. This study, conducted in the Piatra Craiului National Park located in Romania’s Southern Carpathians, we utilize the EFISCEN application to generate three distinct 50-year forest evolution scenarios based on harvest intensity, namely Business As Usual (BAU), Maximum Intensity (MAX), and No Harvest (MIN), on two historical different managed forests, i.e., conservation and production. The study aims to guide forest owners in decision making with scenario modeling tools, with the objectives of assessing the forest carbon sequestration potential and evaluating the economic feasibility. In the most probable scenario, the BAU scenario, the growing stock increases from 2.6 million m3 to 3.8 million m3 over 50 years, with a more than 40% increase. Comparing the carbon stock change for all tree harvest scenario types indicates that the MIN scenario has the highest carbon sink capacity in the next 50 years; the BAU scenario is a well-balanced option between carbon sink and wood provision and has an optimal EUR 3.7 million in annual revenue. The MAX scenario can boost the growth and increase the annual revenue from wood by 35% but is effective only for a short time and thus has the smallest calculated revenue in time. Achieving a win–win relationship between carbon sequestration and wood supply is imperative, as well as good planning and scenarios to contribute to climate mitigation and also as provisions for local communities and to sustain the local economy.

Achieving a win–win relationship between carbon sequestration and wood supply is imperative, as well as good planning and scenarios to contribute to climate mitigation and also as provisions for local communities and to sustain the local economy.","PeriodicalId":37702,"journal":{"name":"Land","volume":"9 7","pages":""},"PeriodicalIF":3.9,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138950302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of smart cities has led to transforming modern city operations by applying emerging technologies from the fourth industrial revolution such as the Internet of Things, BIM and machine learning. To prepare for the future development of cities, it is necessary to investigate the current status of city development, research topics and the direction toward future cities. In this study, a systematic literature review was conducted following the combination of literature review guides by Kitchenham and the PRISMA statement. The review identified 141 peer-reviewed academic papers from web-based archives, such as Web of Science and SCOPUS, that were categorized into five topics related to smart cities and urban areas. The technologies applied in the research were analyzed to determine the direction future cities should take based on current smart cities and emerging technologies that will shape individuals’ daily lives. However, it was discovered that research papers on critical areas, such as mobility and management, were lacking compared to those on building design and urban planning. This paper concludes with an example of a future urban area that has been transformed due to adoption of future mobility technology to address the shortcomings of the reviewed literature on building and urban environments.
通过应用第四次工业革命的新兴技术，如物联网、BIM 和机器学习，智慧城市的发展促使现代城市运营发生变革。为了为城市的未来发展做好准备，有必要调查城市发展的现状、研究课题以及未来城市的发展方向。本研究结合 Kitchenham 的文献综述指南和 PRISMA 声明进行了系统的文献综述。综述从 Web of Science 和 SCOPUS 等网络档案库中找到了 141 篇同行评审过的学术论文，这些论文被归类为与智慧城市和城市地区相关的五个主题。对研究中应用的技术进行了分析，以便根据当前的智慧城市和将影响个人日常生活的新兴技术，确定未来城市的发展方向。然而，研究发现，与建筑设计和城市规划方面的研究论文相比，流动性和管理等关键领域的研究论文较为缺乏。本文最后以一个因采用未来交通技术而发生变革的未来城市地区为例，论述了所查阅的有关建筑和城市环境文献的不足之处。
