基于熵权-模糊层次分析法的矿区 复垦土壤培肥技术研究.

[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/hm2,the amount of biological fertilizer was 2080.15 kg/hm2 , 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.
