Soil enzyme activity is closely related to ecosystem course and function.Tendency and intensity of different biochemical course carried on in the soil was reflected by enzyme activity. This paper deals with the soil enzyme activity, content of organic matter, N,P 'and the relation of the enzyme activity with soil organic matter, N,P in soil of Liangzi Lake wetland by soil samples analyzed. The results shows that in the wetland soil,the urease activity is 0.397-0.652 mg/g ;the phosphatase activity is phenol6.52-11.53 mg/g; The activity of Cellulase in the soil is 0.397 - 0.652 mg/g. The change trend of Cellulase and phosphatase activity throughout the year is summer > autumn > winter > spring. The change trend of urinary enzyme throughout the year is summer > spring > autumn > winter. There is notably positive correlation between the urease activity and soil available nitrogen. There is notably positive corelation between the phosphatase activity and soil available P in the paddy field.There is notably positive correlation between the Cellulase activity and soil organic matter.
