| 摘 要： | 建立模糊综合评价模型,确定包钢尾矿库各理化性质的隶属函数进而计算阈值,采用层次分析法确定各因子的权重值,根据模糊数学中的加成法原则计算采样点的土壤肥力指数,并对包钢尾矿库区域碱化度进行评价,利用地理信息系统(GIS)软件绘制土壤肥力值和碱化度评价图。结果表明,碱化度和土壤肥力的相关系数为0.977,盐碱化直接影响土壤肥力值。

| Abstract: | Seting up the fuzzy comprehensive evaluation model,the membership function of the physical and chemical proper-ties of Baotou tailings area were determined. And the threshold value was calculated. Using the hierarchical analysis method, the weight value of each factor was determined. The sample point index of soil fertility were calculated by the addition method in fuzzy mathematics principle. The alkalization degree of Baotou tailings area was evaluated. And using geographic information system (GIS) software,the value evaluation of soil fertility and the alkalization degree were mapped. The results showed that the correlation coefficient about the soil fertility and the alkalization degree was 0.977. The soil fertility value was directly affected by salinity. |
