为检验煤矸石复垦地复垦效果,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。
為檢驗煤矸石複墾地複墾效果,選取16箇參數作為複墾土壤肥力質量評價的因子,建立攷慮微量元素的肥力質量評價體繫,應用相關繫數法確定土壤肥力因子的權重大小,併結閤模糊數學原理計算土壤肥力評價因子的隸屬度值,運用模糊綜閤評價法對複墾土壤質量進行評價,結果錶明:複墾地與正常農田土壤肥力綜閤指標值均隨深度的增加而降低。複墾土壤的質量在3年內得到瞭逐步的提高,耕作製度、施肥對錶層土壤質量的提高有很大影響。複墾區土壤肥力略低于正常農田,複墾3年時,各層次複墾土壤肥力由上到下分彆為正常農田對應層次的91.9%、89.6%、84.6%,錶明複墾土壤質量已達到正常農田的90%左右,複墾取得良好的效果。

To check the result of land reclamation with coal gangue,this paper chose 16 parameters for appraising re-claimed land fertility quality,established a quality appraisal system taking trace elements into consideration,applied cor-relation coefficient method to determination of weight of each factor in soil fertility quality appraisal,calculated mem-bership value of each factor using fuzzy mathematics principle and performed fuzzy integrated appraisal. The results in-dicated that the reclaimed land and normal farmland both show decreasing soil fertility index values with depth. Re-claimed land soil quality will be improved gradually in 3 years,and both farming system and fertilizer application have great effect on topsoil quality improvement. Reclaimed land soil fertility is a bit lower than normal farmland. After 3 years of reclamation,the fertility of each layer of reclaimed soil equals to 91.9%,89.6% and 84.6% of the counterpart of normal farmland,suggesting that reclaimed soil quality reaches up to 90% of that for normal farmland.
