The soil health of heavy metals in dressing and smelting slag field varies soil physicochemical properties. This study proposed a new soil health index based on heavy metal pollution-buffer-fertility for dressing and smelting slag field. Consequently, spatial distribution of soil physicochemical properties and heavy metals were varied, and correlated to each other. Soil buffer function and fertility played a much more important role in soil health in the dressing and smelting slag field located in Gejiu city, which can result in that soil health indexes were higher than those in Huili county, although the soil heavy metal pollution in the former was severer than that in the latter. Maximum values of soil health indexes for dressing and smelting slag field in Gejiu city were 3.84, 0.61, and 1.75 corresponding to additive, multiplicative, and maximum value composite methods, which were higher than those in Huili county with 2.25, 0.61, and 0.17. The former’s high value is concentrated in southeastern regions and low value in some western areas, the latter’s high value occurred in southeastern districts and low value in northwestern places. So this study unveils a novel perspective on the soil health consequences associated with soil heavy metal pollution-buffer-fertility three aspects.

基于重金属污染-缓冲-肥力3个方面的选冶渣场土壤健康评价


选矿冶渣场重金属的土壤健康状况会改变土壤理化性质。本研究提出了一种基于重金属污染-缓冲-肥力的选矿冶渣田土壤健康指数。因此，土壤理化性质和重金属的空间分布是变化的，并且彼此相关。位于个玖市的选矿冶渣场土壤缓冲功能和肥力对土壤健康起着更重要的作用，导致土壤健康指数高于会理县，但前者土壤重金属污染比惠理县严重。个玖市选冶渣田土壤健康指数最大值分别为3.84、0.61和1.75，分别对应加法、乘法和最大值复合法，均高于会理县的2.25、0.61和0.17。前者高值集中在东南部地区，低值集中在西部部分地区，后者高值出现在东南部地区，低值出现在西北地区。因此，本研究揭示了与土壤重金属污染-缓冲-肥力三个方面相关的土壤健康影响的新视角。
