【摘要】 为检验矿区沉陷地的复垦效果,选取16个参数作为复垦土壤肥力质量评价的因子,建立考虑微量元素的肥力质量评价体系,应用相关系数法确定土壤肥力因子的权重大小,并结合模糊数学原理计算土壤肥力评价因子的隶属度值,运用模糊综合评价法对复垦土壤质量进行评价,结果表明:复垦地与正常农田土壤肥力综合指标值均随深度的增加而降低。复垦土壤的质量在3年内得到了逐步的提高,耕作制度、施肥对表层土壤质量的提高有很大影响。复垦区土壤肥力略低于正常农田,复垦3年时,各层次复垦土壤肥力由上到下分别为正常农田对应层次的91.9%、89.6%、84.6%,表明复垦土壤质量已达到正常农田的90%左右,复垦取得良好的效果。更多还原

【Abstract】 16 parameters were selected as reclamation soil quality evaluation factor to test the reclamation effect of coal mining subsidence land . Fertility quality evaluation system which consider trace elements were established.Correlation coefficient method was used to determine the weight of soil fertility factors.Fuzzy mathematics principle was used to calculate the membership value of the soil fertility evaluation factors.The quality of reclaimed soil was evaluated by fuzzy comprehensive evaluation method.The result shows:The soil fertility colligate index of reclamation land and normal farmland decreased when the soil depth increased.The quality of reclaimed soil improved in 3 years. Farming system, fertilizer had a great influence on the quality of surface soil. The fertility quality of reclaimed soil was lower,which was up to 91.9%,89.6%and 84.6% of control soil from top layer to subsoil.Reclamation had achieved good effect.更多还原
