| 摘 要： | 选取了坡度、土地利用类型、土壤类型、海拔高度、坡向等5个主导评价因子.采用等差指数多因子综合分析与最低限制性因子分析相结合的方法,利用ARCGIS 9.0软件提取相关信息,对南水北调中线工程水源区农耕地进行了分等定级.结果表明,最适宜和中度适宜的土地面积分别占3.4%和36.5%,以中低产田为主;临界适宜和不适宜的土地面积占16.8%和43.4%,具有潜在的宜林宜牧利用价值.研究结果对于水源区制定农业发展政策,科学合理、高效利用土地尤其是耕地资源,实现生态环境保护与经济的协调发展具有重要意义.

| Abstract: | The paper adopts the following five factors: slopes,the types of land use,the types of soil,altitudes and slope directions and makes a combination of analyzing many integrated factors and the lowest limited factors using ARCGIS soft wares to get the related information.Based on the analysis,the article divides the arable lands of South-to-North Water Diversion Project into four grade.The result shows that the most and the more suitable account for 3.4% and 36.5% respectively,which are dominated by the lands... |
