| 摘 要： | 北京西部、北部山区是北京的绿色生态屏障以及主要的水源保护地区，对于北京的生态环境和可持续发展意义重大.由于各种因素，北京山区的局部地区已经出现了水土流失现象，因此研究土壤侵蚀是非常有意义的.以2007年北京一号小卫星数据为源数据，在ArcGIS软件中进行北京西山地区土壤侵蚀等级及分布现状的提取，运用GIS的空间分析功能，对影响土壤侵蚀三大要素进行分析，及时掌握了研究区土壤侵蚀分布状况.结果表明北京西山地区土壤侵蚀面积有所下降.

| Abstract: | The western and northern mountains of Beijing are green barriers,and are major water source protection areas as well,which is of great significance for Beijing's ecological environment and sustainable development.Due to various factors, there has been soil erosion in parts of Beijing mountain areas.Therefore,research on soil erosion is very meaningful.Taking Beijing-1 micro-satellite data of 2007 as source data,ArcGIS software is used to extract the gradation and distribution of soil erosion of Beijing west... |
