摘要
以水土保持学和景观生态学原理为基础,采用野外调查、遥感和地理信息系统技术结合通用土壤流失方程对项目实施前后的土壤侵蚀状况进行了定量计算,得出了项目区土壤侵蚀面积、输沙模数及空间分布信息。利用软件Fragstats3.3对项目实施前后的2个时期栅格格式的土壤侵蚀空间分布数据,从斑块类型尺度和景观尺度研究了6 a间土壤侵蚀的景观格局变化特征。
Based on the principles of landscape ecology and soil and water conservation, and by field investigation, Remote Sensing （RS） and Geographic Information System, combined with the universal soil loss equation, soil erosion situation of project execution were quantitatively calculated. It reached three conclusions .the soil erosion area, the sediment delivery modulus, spatial information. By using software Fragstat3. 3, the landscape scale and the patch type, we studied the characteristics of landscape pattern changes in 6 a.
