Abstract: In order to understand the effect of different vegetation restoration models on soil fertility and soil enzyme activity after the ecological immigrants move out, 7 vegetation models (Picea crassiflolia + Pinus tabuliformis + Populus Hopeiensis, Robinia pseudoacacia + Pinus tabuliformis, Salix matsudana + Robinia pseudoacacia + Prunus armeniaca, Pinus tabuliformis + Prunus armeniaca, Robinia pseudoacacia + Prunus armeniaca + Medicago sativa, Pinus tabuliformis + Salix matsudana + Onobrychis viciaefoli, CK natural restoration) were used as the research object to determine and analyze soil nutrient index and soil enzyme activity. The results show that (1) different vegetation models have significant effect on soil fertility. Model Ⅱ-1 (Salix matsudana + Robinia pseudoacacia + Prunus armeniaca) could increase the soil nitrogen and soil organism, the soil nutrient content of CK is low, which is not conducive to soil nutrient accumulation. (2) Different vegetation models have significant effect on soil enzyme activity. Soil phosphatase and urease activity of Model Ⅰ-1 (Picea crassiflolia + Pinus tabuliformis + Populus Hopeiensis) are better than other models. Model Ⅰ-2 (Robinia pseudoacacia + Pinus tabuliformis) is not conducive to the improvement of soil enzyme activity. (3) Soil catalase has no significant difference in different vegetation restoration models and soil layers. Soil sucrase has positive relationship with TN, AN and SOC, other enzymes have no relationship with soil fertility. (4) There is no significant difference in soil nutrient characteristics and soil enzyme activity between soil layers. Studies have shown that the rational allocation of artificial forest vegetation restoration model in the region is better than the natural recovery model for promoting soil nutrient accumulation and enzyme activity. Therefore, it is an important measure for ecological restoration by artificially constructing plant community structure and redirecting to stable community stage.
