This paper proposes a method for evaluating the ecological value of coral reef resources and garden engineering construction assets. By analyzing the state transition of coral reef ecosystems after multiple disturbances, it is shown that ecological resilience is crucial to maintaining the stability and sustainability of the system. Among the many factors that determine coral reef ecosystems, the loss of biodiversity will make the system more vulnerable to external disturbances and continue to degrade. On the basis of relevant research work at home and abroad, combined with China's coral reef ecosystem monitoring capabilities, a set of evaluation index systems for China's coral reef ecosystems are proposed to provide a reference for in-depth understanding of the resilience of China's coral reef ecosystems, and establish a system to protect and improve coral reefs. Ecosystem-oriented management will provide more options for addressing the degradation of coral reef resources.
本文提出了一种评估珊瑚礁资源和园林工程建设资产生态价值的方法。通过分析珊瑚礁生态系统在多次干扰后的状态转变,说明生态恢复力对维持系统的稳定性和可持续性至关重要。在决定珊瑚礁生态系统的诸多因素中,生物多样性的丧失将使该系统更容易受到外部干扰并持续退化。在国内外相关研究工作的基础上,结合我国珊瑚礁生态系统监测能力,提出一套我国珊瑚礁生态系统的评价指标体系,为深入了解我国珊瑚礁生态系统的恢复力提供参考,建立保护和改善珊瑚礁的体系。以生态系统为导向的管理将为解决珊瑚礁资源退化问题提供更多选择。

Based on the data set of AVHRR GIMMS, TERRA/AQUA MODIS NDVI, and climate data from 1982 to 2018, CASA model, GIS spatial analysis, and mathematical statistics were used to study the changing law in the category of time and space, spatial distribution, and the correlativity between the NPP and meteorological factors in the sandy land of China's Seasonal Freezing-Thawing Typical Region. The results showed that the average annual NPP value of vegetation in the growing season of the sandy land from 1982 to 2018 fluctuated between 217.65-356.61 gC/m2a, showing an obvious seasonality and a significant increase. The spatial distribution of NPP in the sandy land in the near 37a is significantly different. There are significant seasonal differences in vegetation responses to temperature, precipitation, wind speed, evaporation, and other meteorological factors in different regions. The increase of vegetation cover in sandy land of China's Seasonal Freezing-Thawing Typical Region is controlled by regional atmospheric circulation and human dynamics.

A new sludge processing method was developed by the Beta Company, a paper manufacturing company. The new method will shorten the time for transforming sludge into organic fertilizers, which will improve the process of handling the waste generated by a paper manufacturing company. The paper industry is facing the most rigorous regulations for processing wastewater and sludge to date in the history of many industrialized and developing countries. The Beta Company attempted to improve the conventional method implemented in-company for handling sludge generated during the paper manufacturing process, instead of shipping sludge out-of- company for processing by a third party. The current experimental results show positive improvement, indicating the Beta Company is moving one step closer toward environmental sustainability commitments.

Computer vision and image processing procedures could obtain crop data frequently and precisely, such as vegetation indexes, and correlating them with other variables, like biomass and crop yield. This work presents the development of a computer vision system for high-throughput phenotyping, considering three solutions: an image capture software linked to a low-cost appliance; an image-processing program for feature extraction; and a web application for results' presentation. As a case study, we used normalized difference vegetation index (NDVI) data from a wheat crop experiment of the Brazilian Agricultural Research Corporation. Regression analysis showed that NDVI explains 98.9, 92.8, and 88.2% of the variability found in the biomass values for crop plots with 82, 150, and 200 kg of N ha1 fertilizer applications, respectively. As a result, NDVI generated by our system presented a strong correlation with the biomass, showing a way to specify a new yield prediction model from the beginning of the crop.

Before an individual can evaluate wildlife habitat and make management recommendations, some basic concepts about habitat and its relationships to different wildlife species should be understood. In this chapter, some of the basic concepts will be described; mainly analyzing of habitat alterations, landscape analysis, networking and creation of corridor between protected areas, wildlife habitat suitability analysis using Remote Sensing & GIS. Since most of the contest will be based on these concepts. Like other natural resource fields, wildlife management is both an art and science that deals with complex interactions in the environment. This means that management includes art or judgment based on experience as well as sound factual information based on scientific studies.
在个人能够评估野生动物栖息地并提出管理建议之前,应该了解一些关于栖息地及其与不同野生动物物种之间关系的基本概念。在本章中,将描述一些基本概念;主要包括生境变化分析、景观分析、保护区间廊道的联网与创建、利用遥感与GIS技术进行野生动物生境适宜性分析。因为大部分比赛都是基于这些概念。与其他自然资源领域一样,野生动物管理既是一门艺术,也是一门科学,它处理的是环境中复杂的相互作用。这意味着管理既包括基于经验的艺术或判断,也包括基于科学研究的可靠事实信息。

The recent development of sensors remote sensing is an important source of information for mapping and natural and man-made land covers. The increasing amounts of available hyperspectral data originates from AVIRIS, HyMap, and Hyperion for a wide range of applications in the data volume, velocity, and variety of data contributed to the term big data. Sensing is enabled by Wireless Sensor Network (WSN) technologies to infer and understand environmental indicators, from delicate ecologies and natural resources to urban environments. The communication network creates the Internet of Things (IoT) where sensors and actuators blend with the environment around us, and the information is shared across platforms in order to develop a common operating picture (COP). With RFID tags, embedded sensor and actuator nodes, the next revolutionary technology developed transforming the Internet into a fully integrated Future Internet. This chapter describes the use of Big Data and Internet of the Things for analyzing and designing various systems based on hyperspectral images.

In many domains such as environmental and urban planning, experts need to make reasoning and propose solutions. However marketed GIS software products are limited to store, display geographic information together with additional tools such as in spatial analysis, but they do not offer users the real functionalities which are useful for territorial intelligence. This first step is to propose novel models to represent this kind of knowledge needing not only to integrate geographic aspects, but also be independent of data acquisition technologies (satellite images, laser, crowdsourcing, etc.) and able to be used in different languages. After the definitions of geographic ontologies (to organize geographic feature vocabulary) and gazetteers (to structure toponyms in various languages), various examples will be presented in order to extract geographic semantics. A special attention will be devoted to geographic rules.
在环境和城市规划等许多领域,专家需要进行推理并提出解决方案。然而,市场上销售的地理信息系统软件产品仅限于存储、显示地理信息以及诸如空间分析等附加工具,但它们并没有为用户提供对领土情报有用的真正功能。第一步是提出新的模型来表示这类知识,这些知识不仅需要整合地理方面,而且需要独立于数据采集技术(卫星图像、激光、众包等),并且能够以不同的语言使用。在定义了地理本体(组织地理特征词汇)和地名词典(组织各种语言的地名)之后,将提供各种例子以提取地理语义。将特别注意地理规则。

Automatic Estimation of Soil Biochar Quantity via Hyperspectral Imaging 利用高光谱成像技术自动估算土壤生物炭的数量

Biochar soil amendment is globally recognized as an emerging approach to mitigate CO2 emissions and increase crop yield. Because the durability and changes of biochar may affect its long term functions, it is important to quantify biochar in soil after application. In this chapter, an automatic soil biochar estimation method is proposed by analysis of hyperspectral images captured by cameras that cover both visible and infrared light wavelengths. The soil image is considered as a mixture of soil and biochar signals, and then hyperspectral unmixing methods are applied to estimate the biochar proportion at each pixel. The final percentage of biochar can be calculated by taking the mean of the proportion of hyperspectral pixels. Three different models of unmixing are described in this chapter. Their experimental results are evaluated by polynomial regression and root mean square errors against the ground truth data collected in the environmental labs. The results show that hyperspectral unmixing is a promising method to measure the percentage of biochar in the soil.
生物炭土壤改良剂是全球公认的一种减少二氧化碳排放和提高作物产量的新兴方法。由于生物炭的耐久性和变化会影响其长期功能,因此对施用后土壤中生物炭的定量研究非常重要。在本章中,提出了一种土壤生物炭自动估算方法,该方法通过对相机拍摄的可见光和红外光波长的高光谱图像进行分析。将土壤图像视为土壤和生物炭信号的混合,然后采用高光谱解调方法估计每个像元上的生物炭比例。最终的生物炭百分比可以通过取高光谱像元比例的平均值来计算。本章描述了三种不同的分解模型。他们的实验结果通过多项式回归和均方根误差对环境实验室收集的真实数据进行评估。结果表明,高光谱解调是一种很有前途的测量土壤中生物炭百分比的方法。

Because the durability and changes of biochar may affect its long term functions, it is important to quantify biochar in soil after application. In this chapter, an automatic soil biochar estimation method is proposed by analysis of hyperspectral images captured by cameras that cover both visible and infrared light wavelengths. The soil image is considered as a mixture of soil and biochar signals, and then hyperspectral unmixing methods are applied to estimate the biochar proportion at each pixel. The final percentage of biochar can be calculated by taking the mean of the proportion of hyperspectral pixels. Three different models of unmixing are described in this chapter. Their experimental results are evaluated by polynomial regression and root mean square errors against the ground truth data collected in the environmental labs. The results show that hyperspectral unmixing is a promising method to measure the percentage of biochar in the soil.","PeriodicalId":54004,"journal":{"name":"International Journal of Agricultural and Environmental Information Systems","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72959231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
