土壤微量元素与人体健康息息相关.以土壤普查和人口普查数据为基础,运用GIS空间分析及SPSS数理统计方法,对湖北省县域尺度上土壤有效态微量元素空间分异特征进行分析,并对微量元素与人口健康相关性进行探讨.结论如下:1)县域尺度上Zn、B、Mo、Mn、Fe、Cu 6种土壤微量元素分布均存在明显空间聚集特征,B元素的Moran's I值最大,其空间聚集性相对最好,Zn元素的Moran's I值最小,空间聚集性相对最差;空间分布模式中以高值聚类(HH)所占比例最高,同时正热点区域比例均高于负热点区域,不同微量元素之间的正、负热点区域空间分布存在某些一致现象.2)县域尺度上人口健康水平分布存在明显的空间聚集特征,并非...

Soil trace elements are closely related to human health.Based on the data of soil census and population census,the spatial differentiation of soil available trace elements on the county scale of Hubei Province was analyzed by using spatial analysis of GIS and mathematical statistics of SPSS,and the correlation between trace elements and human health was discussed. The results are as follows.1)There are significant spatial aggregation characteristics of soil trace elements including Zn,B,Mo,Mn,Fe and Cu on the county scale,and there is a difference in the degree of aggregation.The Moran's Ivalu...
