摘要 运用层次分析法对研究区域的土壤进行了较为全面、较为科学的评价依据隶属函数确定了各评价指标的隶属度,实现了原始数据的归一化处理;同时也利用主成分分析法确立了各评价因子的权重分配问题。通过对研究区域土壤质量的评价,充分表明了土地利用方式不同对于土壤的改良效果存在明显差别灌木林地>天然草地>农地>人工草地>果园。 The method of arrangement analysis is used to carry through rather complete and scientific evaluation:according to subject function how to decide the degree of function, realizes the transaction of original data to the same dimension;as well as utilizing main ingredient analyzing solves how to determine the distribution of weightiness about every evaluated index. By soil quality evaluation about this area, it indicates the effect of restoration improvement is very different under different land usage mode: bush forest land >natural meadow >farmland >artificial meadow>orchard.
