There are about 100 species plants in the wetland, and the majority is herbage and frutex. These plants included Polygonum hydropiper, Nelumbo nucifera, Annua Linn, Phragmites communis etc. At the same time, there are also 48 species animals, which belong to 30 families, and these animals included Ciconia ciconia, Cygrus cygrus, Platalea leucorodia, Meles meles etc.
