酒泉-湖南±800 kV特高压直流输电线路工程是世界上已建成的电压等级最高、送电距离最长、输送容量最大的特高压直流输电线路工程。由于工程施工会扰动地表,产生弃土石渣,造成严重水土流失,直接危害到项目建设区及周边地区的生态环境,故亟待开展水土保持监测工作。本文利用谷歌地球引擎（Google earth engine, GEE）平台获取中分辨率成像光谱仪（moderate resolution imaging spectroradiometer, MODIS）系列卫星遥感产品数据,采用GIS缓冲区分析和趋势分析定量研究了6年来酒泉-湖南±800 kV特高压直流输电线路湖北段工程周边10 km范围内的生态环境的时空变化特征及其对水土流失的影响,并与野外调...

The project of±800kV ultra high voltage direct current power transmission line from Jiuquan to Hunan is known as the most powerful line among the existing projects all over the world.In other words,it has the highest level of electric voltage,it can deliver the longest distance as well as it can convey the biggest capacity of electricity.It's urgent that we need to keep on monitoring the earth because of the water loss and soil erosion,which is brought by the construction of the project.Also,the construction may do harm on the project itself a...
