Abstract
With the aid of canonical correlation analysis, the relations among soil nutrients, soil microorganisms, and soil enzyme activities were studied in vegetation restoration areas of degraded and eroded soils in the Nverzhai watershed in northwestern Hunan. The main results were as follows: the key factors in soil nutrients, microorganisms, and enzyme activities were N and P elements, number of bacteria, carbon and nitrogen in soil microbial biomass and the activities of urease, polyphenol oxidase, phosphatase, and invertase. The activities of urease and polyphenol oxidase are related to the inversion of N and P elements that had important impact on the accumulation of carbon and nitrogen in soil microbial biomass. Moreover, the activities of urease, polyphenol oxidase, and phosphatase could promote carbon accumulation in microbial biomass; however, invertase activities inhibited the accumulation of microbial biomass nitrogen. On the other hand, urease activities were beneficial to the N element content in soils but unfavorable for P elements. There is a negative relation between polyphenol oxidase activity and N element content. For every canonical variable group, the tendencies of soil nutrients, microorganisms, and enzyme activities to accumulate in different soil layers in different vegetation restoration communities could offer some scientific basis for the diagnosis of the health of the soil and the site type division in the process of vegetation restoration.
