[Objective] The effects of different herbaceous plants on soil nutrients and soil enzyme activities in the Amygdalus pedunculata were studied in order to provide a theoretical basis for vegetation restoration and ecological construction in the subsidence area of coal mines.[Methods] 6 kinds of forest and grass combined cropping patterns[Astragalus adsurgens+Amygdalus pedunculata(SC), Melilotus suaveolens+Amygdalus pedunculata(CC), Medicago sativa+Amygdalus pedunculata(MC), Onobrychis viciifolia+ Amygdalus pedunculata(HC), Coronilla varia+Amygdalus pedunculata(XC), Amygdalus pedunculata(CK)] were used as the research objects. The field plot test method analysis was used to determine the nutrient and soil enzyme activity index of 0-60 cm soil.[Results] ① The organic matter content of different configuration modes significantly increased compared with the control, which was characterized by MC > CC > SC > XC > HC > CK, the trends of total nitrogen, alkali nitrogen, available phosphorus, available potassium and organic matter were similar, and the MC, CC and SC was more obvious, and there was a much smaller increase in HC and XC; ② In addition to urease, the soil enzyme activity was significantly different among different compound configuration modes. The three modes of MC, CC and SC were significantly better than HC and XC; ③ Soil sucrase, catalase and alkaline phosphatase positively correlated with organic matter, total nitrogen, alkali nitrogen and available phosphorus. Urease positively correlated with available phosphorus, and soil enzyme activity and nutrients were closely related. It used to characterize soil improvement effects.[Conclusion] The three forest grass configurations modes of MC, CC and SC had improved the soil nutrient accumulation and enzyme activity. The above three modes should be used to carry out certain vegetation restoration in the subsided land of Yulin coal mine.
