基于模糊数学的复垦土壤综合肥力评价和趋势
|
摘要
采集了平顶山采煤塌陷地复垦土壤和塌陷地、正常农田土壤的表层混合样,测试分析了土壤的养分状况,建立了综合肥力评价指标体系,采用模糊数学方法计算了各指标的隶属度。结果显示:复垦11年、6年、4年和2年的土壤综合肥力指数为0.69、0.73、0.65和0.62;用SPSS 13.0对复垦土壤的肥力演化进行了回归分析,提出了回归函数模型。为评价煤矿塌陷区复垦地土壤肥力质量水平,提供了定量的科学的方法;为土地复垦的验收,以及复垦地土壤的改良提供科学的依据。
The paper takes subsided land in Pingdingshan Coal Mine as an example,surface soil samples of reclaimed land,subsided land and normal cultivated land are collected and determined.The paper sets up indicator system of comprehensive evaluation of soils fertility of reclaimed land.Subordinate functions of evaluation indexes are calculated by the way of Fuzzy mathematics.The result shows that:the integrated fertility indexes of reclaimed soil are: 11years,0.69;6 years,0.73;4 years,0.65;2 years,0.62.The curve regression of change tendency of the soil fertility in reclaimed land is made by using SPSS 13.0.And the regression function is presented.The purpose of the paper is to provide scientific basis for approval and amelioration of soils of reclaimed land,and to take references for studies similar area.
