Investigation and analysis on reclaimed land agricultural environment in coal mining subsidence

为了更清楚的掌握采煤沉陷复垦区的复垦效果,应用土壤学与环境保护等学科的相关理论,采取室外调查与室内分析相结合的研究方法对采煤沉陷治理区农业环境进行了调查与分析。结果表明:改良后的采煤沉陷复垦区耕地土壤肥力基本达到了中等肥力水平,土壤重金属污染物符合我国土壤环境质量二级标准,水体重金属含量符合我国农业用水标准。

In onier to k n o w the reclamation efect of coal reclamation area, the theorysprotection were used, the research metliods of outdoor investigation and indoor analysis were used to investigate andanalyze the agricultural environment in coal reclamation area. T h e results showed that the soil fertility land in coal reclamation area reached the middle fertility level, and the heavy - metal contentheavy metals meet the secondary standard of soil environmental quality, the water quality ricultural water standard.
