| 摘 要： | 通过对煤矿塌陷区复垦土壤采样测试,研究土壤中重金属铜、锌、镉、汞、砷、铅、铬的含量对土壤环境的影响。研究结果表明:按单因子污染指数法和内梅罗综合污染指数法,结合国家土壤环境质量标准对复垦土壤的质量进行评价:研究区内土壤环境质量良好,基本上可以达到国家土壤环境质量二级标准,安全清洁级别;参照《无公害食品蔬菜产地环境条件标准》、《绿色食品产地环境质量标准》和《有机农业生产基地环境质量标准》,对复垦土壤的农用环境进行评价:研究区内土壤全部达到绿色食品产地环境质量标准,如果选择合理的修复方法,对部分有轻微污染的土壤进行,则可以达到有机农业生产基地环境质量标准;以潜在生态危害指数RI分析,复垦区内土壤重金属潜在生态危害指数相对较低,复垦区农业生产具有良好的发展前景。

| Abstract: | Based on test of samples from reclaimed soil in the coalmine cave-in area, this paper studied the effect of contents of heavy metals of Cu, Zn, Cd, Hg, As, Pb and Cr on soil environment. The results indicate that according to one-factor pollution index method and Nemero comprehensive pollution index method, along with national soil environment quality standard, soil environment quality is good in the studied area, and on the whole reaches national class-2 standard, the category of safeness and cleanness; according to the Pollution-free Food and Vegetable Production Base Environment Conditions Standard, Green Food Production Base Environment Quality Standard and Organic Agricultural Production Base Environment Quality Standard, the soils in the studied area all meet the Green Food Production Base Environment Quality Standard. If a reasonable remediation method is applied to some slightly contaminated soils, all the soils in the studied area can meet the Organic Farm Production Base Environment Quality Standard. Based on hidden ecological hazard index RI analysis, hidden heavy metals hazard is relatively low and agricultural production has good development prospect in the reclaimed area. |
