This paper is focused on exploring ecological and environmental applications to wetland park planning, by the example of wetland park planning of ShengZe lake of Suzhou. Planning strategy were established through ecological structure design based on study on ecological elements and the interaction characteristics. The principles of ecology and environment were used to guide planning and design. wetland park planning methods were proposed by the research on the temporal and spatial ecological structure, and then ecological and environmental functions of wetland park were implemented through spatial distribution patterns based on the temporal and spatial ecological structure. Through the research, this paper draw a conclusion that methods of wetland park planning based on ecological and environmental applications are effective.
