Abstract: Explorie and assess the relationship between soil enzymatic activities and soil nutrients to screen several biological attributes in soil quality indication. cotton field soil in south Xinjiang was used as tested samples, soil enzymatic acitivites as well as soil nutrients were determined. Correlation analysis, path analysis and principal component analysis were employed for data processing. Significant correlations were found within soil enzymes and soil nutrients as well as the interaction of soil enzymes and soil nutrients. Total N and organic matters contents were the most important factors determining soil enzymatic activities, which discovered by path analysis. Soil enzymatic is a crucial component in soil fertility and quality. Conclusion catalase, acidic invertase and alkaline phosphatase can be used as applicable biological indicators in the assessment of cotton soil fertility.
