We present a comprehensive analysis of soil nutrients of different types of plant diversity in Jialing River Basin from 2013 to 2015, based on the plant diversity and soil habitat, the relationships between the plant diversity and soil nutrients has been studied by correlation analysis and redundancy analysis. The results are as follows. (1) The plant diversity index, richness index, dominance index and coverage showed the order:arbor > shrub > meadow > bare land, and bare land was significantly lower than other plant types (p < 0.05). (2) The soil bulk density and pH value had the same variation trend which showed the sequence:bare land > meadow > shrub > arbor, and soils of different plant types were acidic except shrub and bare land. (3) The soil nutrients, available nutrients and soil enzyme activity showed the order:arbor > shrub > meadow > bare land, and bare land was significantly lower than other plant types (p < 0.05). (4) Correlation analysis showed that the plant diversity had a significantly positive correlation with soil nutrients and enzyme activity, which was the important cause of different plant types of soil nutrient. Soil nutrients and enzyme activity determined the plant richness and diversity to a certain extent, and soil physical and chemical properties determined the plant dominance, while soil total carbon and total nitrogen determined the plant coverage to a certain extent in this study. (5) Redundancy analysis indicated that there was the positive correlation between plant coverage, richness index, diversity index and dominance index, also had a positive correlation with soil nutrients and enzyme activity, while had a negative correlation with pH value and soil bulk density which was the same as the above results.
