Spatial plan decisions guide both the future use of the lands and many activities from protection to construction and permit. Due to its functions, spatial plan decisions play a key role in land administration. Spatial planning information for integrated land administration systems (LASs) should be associated with land registration systems. The Land Administration Domain Model (LADM) standard offers components to enable this structure. Integrating spatial plan data with LASs will provide standardization for plan data and assurance of plan decisions. Although the spatial planning mission differs across various administrative regions, planning activities produce land use decisions, albeit in different ways. The study aims to establish the common points in planning activities and design a joint spatial planning system data model using various countries' spatial planning systems and international standardization studies. The spatial plans in the model that has been proposed are depicted as a system, not merely by the rights, restrictions, and responsibilities (RRRs) that they establish on the land. The results point out that spatial planning systems have some similarities but also some limitations to support conceptual model design. Based on joint data and relationships, the proposed spatial planning system data model can be adapted for different country practices. The study's results are expected to support the LADM second version development studies.
空间规划决策既指导土地的未来使用,也指导从保护到建设和许可的许多活动。由于其功能,空间规划决策在土地管理中起着关键作用。综合土地管理系统(LASs)的空间规划信息应与土地登记系统联系起来。土地管理领域模型(LADM)标准提供了支持这种结构的组件。将空间规划数据与LASs集成将为规划数据提供标准化,为规划决策提供保障。虽然不同行政区域的空间规划任务不同,但规划活动产生土地使用决策,尽管方式不同。本研究旨在利用各国空间规划体系和国际标准化研究,建立规划活动的共同点,设计联合空间规划体系数据模型。所提出的模型中的空间规划被描述为一个系统,而不仅仅是由它们在土地上建立的权利、限制和责任(RRRs)来描述。结果表明,空间规划系统在支持概念模型设计方面具有一定的相似性,但也存在一定的局限性。基于联合数据和关系,所提出的空间规划系统数据模型可适应不同国家的实际情况。该研究的结果有望支持LADM第二版开发研究。

This study addresses a crucial gap in our understanding of flooding in the predominantly agricultural Qaa'Jahran watershed in Yemen, where urbanization, though currently limited in extent, is rapidly expanding. We aim to discern the effects of earth fissures on flood dynamics, particularly focusing on their present significance. It is noteworthy that, in the long run, these fissures are anticipated to accumulate soil and sediment, potentially heightening the risk of future flooding. To achieve this, we developed a comprehensive floodplain delineation model, incorporating field observations and rainfall data from the Integrated Multi-satellitE Retrievals for GPM (IMERG) algorithm. Additionally, advanced hydrologic and hydraulic models were integrated to accurately simulate runoff hydrographs and create flood inundation maps. Our findings underscore the considerable influence of earth fissures, effectively mitigating runoff volume, peak discharge, flood depths, and inundated areas during storm events. It is imperative to emphasize that specific areas remain persistently vulnerable, with water levels surpassing one meter during historical floods. This reinforces the ongoing risk of flooding in targeted zones and emphasizes the necessity of implementing tailored flood management strategies. In conclusion, this study makes a significant contribution to the field, providing a comprehensive analysis of the intricate factors influencing flooding in the Qaa'Jahran watershed. The integration of flood inundation mapping, advanced hydrologic modeling, and meticulous consideration of earth fissures offers a distinctive perspective on flood dynamics in a rapidly evolving and urbanizing environment. Furthermore, it highlights the critical implications for effective flood risk management and urban planning, not only in the Qaa'Jahran watershed but also in similar urbanizing regions worldwide.
这项研究弥补了我们对也门以农业为主的Qaa' jaahran流域洪水的理解上的一个关键空白。也门的城市化虽然目前程度有限,但正在迅速扩大。我们的目的是辨别地裂缝对洪水动力学的影响,特别是侧重于它们目前的意义。值得注意的是,从长远来看,这些裂缝预计会积聚土壤和沉积物,潜在地增加未来洪水的风险。为了实现这一目标,我们开发了一个综合的洪泛区划分模型,该模型结合了来自GPM (IMERG)算法的野外观测和降雨数据。此外,还集成了先进的水文和水力模型,以精确模拟径流水文曲线并创建洪水淹没图。我们的研究结果强调了土裂缝的巨大影响,有效地减少了暴雨期间的径流量、峰值流量、洪水深度和淹没面积。必须强调的是,某些地区仍然很脆弱,在历史上的洪水中,水位超过一米。这增加了目标地区持续存在的洪水风险,并强调了实施量身定制的洪水管理战略的必要性。综上所述,本研究为Qaa' jaahran流域洪水的复杂影响因素提供了全面的分析,对该领域做出了重大贡献。洪水淹没制图、先进的水文建模和对地裂缝的细致考虑相结合,为快速发展和城市化环境中的洪水动力学提供了独特的视角。此外,它强调了有效的洪水风险管理和城市规划的重要意义,不仅在Qaa' jaahran流域,而且在世界范围内类似的城市化地区。

A method for measuring geometric information content of area cartographic objects based on discrepancy degree of shape points 一种基于形状点差异度的区域地图学对象几何信息含量测量方法

In order to improve the comparability between the geometric information content of vector area objects, this paper proposes a method for measuring the geometric information content of area objects based on discrepancy degree of shape points. Firstly, the method selects circles with unique geometric feature as the reference shape for extracting geometric features, and the geometric in-formation carried by each shape point of area objects is represented by the discrepancy degree between the area object and the reference circle at the point position. Secondly, the proposed method measures the geometric information content of area objects from both local and global perspectives. To avoid the subjectivity of assigning feature weights based on empirical experience, the paper uses the relationships between the radii of three reference circles (MIC: Maximum Inscribed Circle, EAC: Equal-area circle, and MCC: Minimum Circumscribed Circle) as adaptive weight parameters for local and global structural geometric information. The amount of geometric information at each shape point is obtained by weighted summation, and the total geometric information content of an area object is the sum of the amount of geometric information of all shape points. To verify the effectiveness and rationality of the proposed method, this paper designs a noise simulation dataset for simply building area objects and an empirical ranking dataset for evaluating the measurement performance of the proposed method. The experimental results show that the proposed method achieves a Kendall rank correlation coefficient of 0.88 on the empirical ranking dataset, which is higher than that of the nine existing representative methods. The proposed method is more consistent with human cognition and is highly correlated with the amount and intensity of noise information. Moreover, the proposed method achieves the comparability of geometric information content of area objects and the adaptive determination of geometric feature weights. The proposed method is an effective method for measuring the geometric information quantity of area objects.
为了提高矢量面积目标几何信息量之间的可比性,本文提出了一种基于形状点差异度的面积目标几何信息量度量方法。该方法首先选取具有唯一几何特征的圆作为参考形状提取几何特征,并将区域对象的每个形状点所携带的几何信息表示为该区域对象与参考圆在点位置的差异程度。其次,该方法从局部和全局两个角度测量区域目标的几何信息含量;为了避免基于经验分配特征权重的主观性,本文采用三个参考圆(MIC:最大内切圆,EAC:等面积圆,MCC:最小外切圆)半径之间的关系作为局部和全局结构几何信息的自适应权重参数。每个形状点的几何信息量通过加权求和得到,一个面积对象的总几何信息量为所有形状点的几何信息量之和。为了验证所提方法的有效性和合理性,本文设计了简单建筑面积目标的噪声模拟数据集和评价所提方法测量性能的经验排序数据集。实验结果表明,该方法在经验排序数据集上的肯德尔秩相关系数为0.88,高于现有的9种代表性方法。该方法更符合人类的认知,并且与噪声信息的数量和强度高度相关。此外,该方法还实现了区域目标几何信息含量的可比性和几何特征权重的自适应确定。该方法是一种测量面积目标几何信息量的有效方法。

This study evaluated performances of the Climate Hazard Group Infrared Precipitation with stations version 2.0 (CHIRPS v2.0) and Multi-Source Weighted-Ensemble Precipitation version 2.8 (MSWEP v2.8) products against observed data. Rainfall climatology was simulated for different agro-ecological zones (AEZs) of Ethiopia during 1991-2020 at different temporal scales. Performance evaluations were made using continuous and statistical performance measures as well as Probability Density Function (PDF). CHIRPS v2.0 for estimating monthly, seasonal, and annual rainfall totals, and MSWEP v2.8 for daily rainfall have shown better performance over all AEZs. The two products display comparable performance for detecting daily rainfall occurrences over alpine AEZ, but MSWEP v2.8 is superior in the rest four AEZs. CHIRPS v2.0 outperforms MSWEP v2.8 for detecting most of the daily rainfall intensity classes over all AEZs. The findings will play a noteworthy role to improve the quality of hydro-climate studies in Ethiopia.
本研究利用实测数据,对气候危害组红外降水(CHIRPS 2.0版)和多源加权集合降水(MSWEP 2.8版)产品的性能进行了评价。对1991—2020年埃塞俄比亚不同农业生态区在不同时间尺度上的降雨气候学进行了模拟。使用连续和统计性能度量以及概率密度函数(PDF)进行性能评估。用于估算月、季和年总降雨量的CHIRPS v2.0和用于估算日降雨量的MSWEP v2.8在所有aez中都显示出更好的性能。这两种产品在检测高山AEZ上的日降雨量方面表现相当,但MSWEP v2.8在其余四个AEZ上表现更好。CHIRPS v2.0在检测所有aez的大多数日降雨强度等级方面优于MSWEP v2.8。这些发现将对提高埃塞俄比亚水文气候研究的质量发挥重要作用。
