摘  要：
为了筛选出一种适宜的表土替代材料,以5种采矿剥离物为原料,制成不同粒径配比的表土替代材料,通过室内盆栽试验测定其理化性质,对比分析各处理的养分指标,利用模糊综合评价法对表土替代材料养分指标进行评价,选出最优配比。结果表明,pH是表土替代材料养分指标评价的重要因子,在各个养分指标的含量中速效钾水平最高,其次为有效磷,而有机质和碱解氮的含量较低;变异系数从大到小依次为碱解氮>有机质>有效磷>速效钾>pH。主成分分析结果表明,各指标权重分别为pH 0.28、速效钾0.26、碱解氮0.23、有效磷0.21、有机质0.02;模糊综合评价结果表明,4A配比[其粒径配比1号剥离物(2.0～3.0 mm):2号剥离物(2.0～3.0 mm):3号剥离物(1.0～2.0 mm):4号剥离物(1.0～2.0 mm):5号剥离物(0.5～1.0 mm)=4∶4∶2∶1∶3]是此次试验的最优配比。

摘  要：
In order to screen out a suitable topsoil substitute material, this study used five mining stripped materials as raw materials to make topsoil substitute materials with different particle size ratios.The physical and chemical properties were measured through indoor pot experiments, and the nutrient indicators of each treatment were compared and analyzed.The fuzzy comprehensive evaluation method was used to evaluate the nutrient index of the topsoil substitute material, and select the optimal ratio.The results showed that pH was an important factor for the evaluation of nutrient indicators of alternative topsoil materials.Among the content of various nutrient indicators, the level of available potassium was the highest, followed by available phosphorus, while the content of organic matter and alkaline nitrogen was lower; the coefficient of variation: alkaline nitrogen > organic matter> effective phosphorus>available potassium>pH.Principal component analysis results showed that the weight of each indicator was pH 0.28,available potassium 0.26,alkaline nitrogen 0.23,available phosphorus 0.21,organic matter 0.02.The fuzzy comprehensive evaluation results showed that the 4 A ratio [the particle size ratio No.1 stripper(2.0-3.0 mm):No.2 stripper(2.0-3.0 mm):No.3 stripper(1.0-2.0 mm):No.4 stripper(1.0-2.0 mm):No.5 peeling object(0.5-1.0 mm)=4∶4∶2∶1∶3]was the optimal ratio of this test.
