农牧交错区生态环境质量遥感动态监测——以宁夏盐池为例OA北大核心CSCDCSTPCD
Dynamic monitoring of ecology and environment in the agro-pastral ecotone based on remote sensing: a case of Yanchi County in Ningxia Hui Autonomous Region
以26 a(1989-2015年)4期Landsat TM/OLI遥感数据为基础,提取不同年份的湿度指数、植被指数、地表温度以及土壤指数,利用主成分分析法,构建盐池县4个时期遥感生态指数(RSEI)和生态环境质量综合指数(ESI),对其生态环境质量进行了评价,探讨区域生态环境的时空变化特征.结果表明:(1)湿度、绿度对区域生态环境质量起正面作用,而热度和干度则起负面作用,其中代表绿度指标的植被覆盖度(NDVI)对生态指数的贡献最大.(2) 198…查看全部>>
The ecological environment is closely related to human life.Rapid and effective evaluation of regional ecological environment quality and spatial-temporal changes is helpful to understand the status of regional ecological environment,and provide the basis of development trends for the regional ecological environment protection and sustainable development.In the past few years,remote sensing ecological index (RSEI) based on PCA has been increasingly more wide…查看全部>>
