- Title:
- Completion of Xining City Soil Erosion Monitoring Based on GIS
- Keywords:
- GIS; Xining City; soil erosion; monitoring
- 分类号:
- S157;TP79
- 摘要:
- 介绍了应用地理信息系统技术,建立西宁市DEM模型,提取地形地貌指标,划分西宁市小流域,并且引进USLE方程对西宁市的土壤侵蚀进行计算分析,得出西宁市土壤侵蚀分布情况.
- Abstract:
- The establishment of Xining city DEM model and deriving of topographic feature and classification of watershed are described.Finally the situation of soil erosion is analyzed with USLE equation and a conclusion on soil erosion distribution is drawn.
