In order to understand the w etland degradation processes, sampling and survey on plant community w ere conducted by selecting the typical w etland plots. Meanw hile, soil features including organic matter, nutrients, and physiological characters, as w ell as some soil enzyme activities w ere analyzed. Results show ed that the plant succession w as form Imp erata cyli
