In Songnen Plain, there is about 16 340 square kilometres of saline-alkaline wetland, which mainly consist of a lot of alkaline lakes, now occupying an important place in the system of regional resources environment.The saline-alkaline wetland is the result of saline-alkalization of wetland, showing degeneration of entironment.It has great significance to harness and develop saline-alkaline wetland either for the recovery of enviroment or the development of agriculture.Among the alkaline lakes, there are a lot of alkalescence lakes and ponds, which form special kind of wetland and occupy an important position in the system of regional resources environment.Yaopao Lake is one of the typical alkalescence lake wetlands in the Songnen Plain.Its ecosystem boasts such excellence as better bio-diversity and short food chains.But the quantitative relation of animals and plants reflected the shortages of imbalance of ecosystem structure and functional disorder.Finally, the paper points out such concrete measures for eco agricultural development as fishery, breeding of poultry, planting rice and reed according to the ecosystem characteristics in order to build the model of paddy-reed-fishery-poultry-domestic animal livestock.
