A preliminary study on the soil enzyme distribution in typical plant community in Ebinur Lake area

Soil enzymes and soil organic matter,salinity,pH value are measured in the Ebinur Lake near Dongdaqiao and Duck bay,including 38 typical places which content 17 kinds of plant communities,21kinds of plants involved. The result indicats that compared with the moist area,the soil enzyme content in the arid area is very low. In the soil profile the tendency of enzyme activity is reducing from top to bottom. Soil enzyme is the most important element in cluster analysis,different plants divided to the same type have close relationship in the soil physical and chemical properties,the mechanism that they adapting to the environmental stress is similar. Combining with the classical plant classification methods,cluster analyses which provide more rational basis for the classification of plants can be used to classify plant. The correlation analysis indicats that soil organic matter is significantly related to the soil enzyme activity,as a source of runoff for soil enzyme,the soil organic matter is an important index of the level of soil fertility.
