摘要
基于遥感和地理信息系统技术 ,利用“通用土壤流失方程”USLE模型A =R·K·S·L·C·P和土壤侵蚀防治预报模型Y =CP -C′P′,采集生成因子数据 ,并通过投影及坐标转换 ,生成像元点的因子图 ,使每个 30m× 30m的像元点都具有以上 6个因子数据 ,之后 ,利用模型进行计算 ,生成分幅的土壤侵蚀强度图和土壤侵蚀强度防治预报图及统计结果 .此方法的研究使快速、经济、定量、定期地实现土壤侵蚀调查成为可能 。
Based on remote sensing & Geographical Information System technology,the model of soil erosion degree( A=R·K·S·L·C·P ) and prevention model of soil erosion ( Y=CP-C′P′ ) were used,the factor data were collected,projected and transformed,then the factor maps based on pixel were created,the every pixel of 30 m× 30 m in factor maps has consisted of six factor data,at last,based on above results,the maps of soil erosion degree and maps of soil erosion prevention in scale 1∶100 000 were created.It is possible that soil erosion investigation with above method based on remote sensing & GIS technology will be carried out quickly,economically,quantitatively,and timely.The method of soil erosion investigation based on remote sensing & GIS technology will provide scientific basic data for strategies of soil erosion prevention and soil protection.
