影响福建土壤侵蚀的景观因子分析
Analysis of Landscape Factors on Soil Erosion in Fujian
【摘要】 应用福建省5类因子分布图和福建省土壤侵蚀强度图,以地理信息系统为依托,建立了全省各因子图形数据库。在此基础上,采用3种不同的数值方法计算出各因子类型的侵蚀强度系数、多样化指数和集中化指数,分析了它们的因子分异,得出各因子类型的土壤侵蚀强度特征分异,为进行福建省土壤侵蚀景观系统分类提供依据
【Abstract】 Supported by geographic information system (GIS), the author institutes aset of graphic data base of landscape factors according to five maps of landscape factors and the intensity map of soil erosion in Fujian. On the basis of above works, the author calculate the intensity coefficient of soil erosion,index of diversification and centralisation of factor types using three evaluation methods, and then analyses the factors’ discrepancies of them.the characteristic discrepancies of factors are gotten throughing above analyses.All of above supply landscape systematic classification of soil erosion with foundation.
【Key words】 intensity coefficient of soil erosion; index of diversification; index of centralisation; factor discrepancyncy;
