摘　　要：【目的】本文获得了矿区复垦条件下土壤培肥的最优组合。【方法】选取山西省朔州市的平朔矿区为研究试验区,基于试验数据分析不同配肥方式矿区复垦土地土壤生化成分、生物多样性和玉米生物性状的影响的前提下,构建基于熵权法的模糊层次分析体系计算土壤配肥效应指数为应变量,以该指数为应变量,生物肥和化肥编码为自变量建立回归拟合预测模型。【结果】生物有机肥与化肥配施处理的土壤复垦效应指标高于单施化肥S和单施生物肥S,当化肥量为220.15 kg/hm^2,生物肥量2080.15 kg/hm^2时,土壤培肥效应指数可达最大值0.9909。【结论】本文提出的矿区土壤复垦效应综合评价体系和预测模型具有较高的可靠性,对于实际生产具有一定的指导作用。【Objective】This paper aimed to obtain the optimal combination of soil fertilization under mining area reclamation conditions.【Method】Based on the experimental data analysis of the effects of biochemical composition,biodiversity and maize biological characteristics of reclaimed land in mining area under different fertilization modes,a fuzzy analytic hierarchy process(FAHP)system based on the entropy weight method was constructed to calculate the soil fertilization effect index as the strain variable,and the index as the strain variable,and the regression fitting prediction model with chemical fertilizer coding and biological fertilizer as independent variable was established.【Result】The index of soil reclamation effect of combined application of bio-organic fertilizer and chemical fertilizer was higher than that of single application of chemical fertilizer S and biological fertilizer S.When the amount of chemical fertilizer was 220.15 kg/hm^2,the amount of biological fertilizer was 2080.15 kg/hm^2,and the index of soil reclamation effect could reach the maximum value of 0.9909.【Conclusion】The comprehensive evaluation system and prediction model of soil reclamation effect in mining area proposed in this paper are of high reliability and have certain guiding effect on practical production.
