摘　　要：文中针对采煤塌陷地,应用农学、土壤学、以及植物营养学等学科的相关理论,采取田间模拟试验的方法进行了煤矸石充填复垦耕地覆土厚度的研究。结果表明:在同一条件下,30cm的覆土厚度限制了农作物的生长;50cm的覆土厚度对农作物的生长而言优于30cm,劣于70cm;而覆土厚度70cm、100cm、以及对照田块之间差异不显著。综合分析表明,70cm左右的覆土厚度是采煤塌陷区土壤重构较为经济合理的覆土厚度。In the paper, a research is made on depth of the covering layer on reclaimed cultivated land backfilled with coal refuse in coal mining induced subsidence area by using the method of simulation test in the field based on theories related to some subjects, such as agriculture, pedology and plant nutriology etc. The results obtained show that growth of the crops, under the same condition, is limited when the depth of the covering layer is 30cm, is better than that when the depth is 30cm and worse than that when the depth is 70cm, and has no obvious disparity when the depth is between 70cm and 100cm. Further comprehensive analysis indicates that 70cm is relatively economic and rational depth of the covering layer for soil reconstruction in coal mining-induced subsidence area.
