宁南山区不同土地利用方式土壤质量评价方法研究
- Title:
- Method of Soil Quality Evaluation Under Different Land Use in Southern Ningxia Mountain Area
- Keywords:
- mountain area of southern Ningxia; soil quality evaluation; the method of arrangement analysis; subject function; main ingredient analyzing
- 分类号:
- F301.24
- 摘要:
- 目前关于土壤质量评价的方法很多，综合了多变量指标克立格法、土壤质量综合评分法和土壤相对质量评价法各种方法的优点，也融入了本地区的土壤特性研究，制定了有区域特色的层次分析法；确立了隶属函数及其中的参数，因而实现了原始数据的归一化处理；同时也解决了利用主成分分析法如何决定各评价因子的权重分配问题。
- Abstract:
- At present, there are a lot of methods concerning soil quality evaluation, integrating with the goodness of multiple variable indicator transform, synthetically graded method of soil quality and the method of soil relatively quality evaluation and the soil feature of this area, the method of arrangement analysis is made; subject function and their parameter are established, so it 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.
