基于RUSLE模型的铜仁地区1987—2015年土壤侵蚀时空特征
Using RUSLE Model to Analyze Temporal and Spatial Characteristics of Soil Erosion in Tongren Area From 1987 to 2015
摘要
Abstract
Based on digital elevation model (DEM), daily rainfall, land use date and remote sensing imagery as basic data, combined with GIS, RS techniques and landscape pattern analysis tool, the modified revised universal soil loss equation (RUSLE) was used to analyze temporal and spatial distribution characteristics of soil erosion in Tongren Area from1987 to 2015. The results show that the soil erosion in the study area was relatively serious from 1987 to 1995. However, From 1995 to 2015, the soil erosion was significantly improved. During this period, the soil erosion intensity in most areas and karst trough areas shifted to a lower level. Among them, the violent and extremely strong grade erosions were mostly transferred to the moderate and mild grades. From the perspective of landscape pattern, the soil erosion status was increasingly dominated by the slightly erosion and mild erosion landscape types.关键词
