山地土地类型质量评价模式

                               

式中,W为环境要素评分(0~100);k为环境要素序号(1~5);i为环境要素各因子序号(设有p因子);j为因子等级序号(设分g等级);α为因子生态效应权重(0~1);S为因子不同等级面积比例;F为因子等级评分。

      将各环境要素的资源潜力分值按各自在环境中效应权重进行加权组合,求出各土地类型单元质量潜力分。以分值大小表示其质量的优劣。评价模式如下:

                           

式中,En为第n个土地类型单元的质量分值,n为土地类型单元序号(1~40);k要素权重;k要素在第n个土地类型单元的评价分值。
