美国国会确定留用地保护项目（CRP）的最初国的是为减少农用地边缘的土壤侵蚀。全美目前有2.43×1.06hm2农田登记纳入该项计划。对该项目减少侵蚀的有效性评价将对其令后的实施修订有很大应用价值。在堪萨斯州Finney县利用卫星图像导出土壤使用和覆差情况图。通过地理信息系统（GIS）将该图与计算机编程的土壤探测信息（SSURGO）结合，对每种利用地块类型（去除了该县的最高侵蚀系数和最易受侵蚀的地块）土壤特性和侵蚀系数进行分析，该研究表明CIS和遥感技术对评价和监测该留用地保护计划有许多优点。
The US Congress decided to retain the land-use rights protection project (CRP) in its first country to reduce soil erosion on the edge of agricultural land. There are currently 2.43 × 1.06hm2 farmland registrations in the United States. The evaluation of the effectiveness of the project to reduce erosion will have great application value to the subsequent revision. Use of satellite imagery in Finney County, Kansas to derive maps of soil use and coverage. The map was integrated with computer-programmed soil-detection information (SSURGO) through a geographic information system (GIS), and for each type of soil (excluding the highest erosion coefficient and the most susceptible patch in the county) soil characteristics and The erosion coefficient analysis shows that CIS and remote sensing technologies have many advantages for evaluating and monitoring this reserve protection plan.
