基于GIS的土壤侵蚀与土地利用关系研究

Research on the Zelationship Between Soil Erosion and Land Use Based on GIS

以衡阳盆地为例,基于GIS技术和土壤侵蚀综合强度等指标,在分析土壤侵蚀现状的基础上,通过对比不同土地利用类型的土壤侵蚀特征及各等级土壤侵蚀的面积占比分布情况,研究丘陵坡地地貌土壤侵蚀与土地利用之间的关系。

Taking Hengyang Basin for example,based on GIS technology and soil erosion indicators to research the relationship between soil erosion and land use in hilly slope topography by comparing the soil erosion characteristics of different land uses and the area percentage of different soil erosion grades,after the analysis of the status of soil erosion.
