摘要
Abstract
Taking Huangfuhuan basin as the study area,based on different periods of digital aerial photography,using ArcGIS software,through visual interpretation and comprehensive judgment,it extracted the measures of soil and water conservation,the vegetation coverage and the soil ero-sion data in 2006 and 2011 respectively,determined its transfer matrix and analyzed the dynamic change of the soil and water conservation meas-ures,the vegetation coverage and the soil erosion intensity in Huangfuchuan basin. Results show that in five years,in Huangfuchuan basin,the net variation of soil and water conservation measures is 78km2 ,accounting for 2. 4% of the total area of the basin,change order is forest>shrub>ditch terrace>arbor;The net change in vegetation coverage is 33km2 ,accounting for 1. 0% of the total area of the basin,change order is low coverage>medium and low coverage > medium coverage;Net variation of soil erosion intensity is 60km2 ,accounting for 1. 85% of the total area of the ba-sin,the gully erosion change is smaller,surface erosion change order is moderate>strong>micro degrees>mild>very strong>intense.关键词
