黄河中游多沙粗沙区水土流失动态变化分析
Analysis of Dynamic Change of Soil and Water Loss in the Middle Yellow River Basin
摘要
Abstract
This paper selected two periods of remote sensing images in four typical basins relating to Junggar and Shenmu Counties, including Huangfuchuan River, Gushanchuan River, Kuye River and Tuwei River in the middle Yellow River basin and extracted the information of land use, vegetation coverage and soil erosion in 2011 and 2014 to analyze the ecological environment and to reveal the area of soil erosion and its control effect combining with runoff and sediment data. The results show that the vegetation coverage is dominant from low coverage and low⁃medium coverage in 2011 to low⁃medium and medium coverage in 2014;land use change mainly concentrates in woodland, grassland and other lands;the intensity of soil erosion and area of soil and water loss decreases significantly; the implementation of soil and water conservation measurements plays a positive role in reducing runoff and sediment, and the ecological environment improves significantly.关键词
