Research on the design of Guangzhou Tianhe WetlSince the reform and opening up, China's cities have experienced a rough development stage of unilaterally pursuing economic growth, which has produced many ecological problems, among which water safety and water quality have become one of the prominent problems plaguing urban development. In order to cope with water problems, many developed countries have put forward different solution strategies based on their own characteristics and needs. In 2014, the Ministry of Construction announced the Guidelines for Sponge City Construction, marking the comprehensive start of sponge city planning and construction. As the lungs of the city, urban wetland parks have large water bodies and green spaces, which become the best practice sites for the concept of sponge city; at the same time, as a park, it is also one of the important components of the urban public space system, which is closely related to people's daily life, and the organic combination of wetland parks, wetland ecological protection, and public space design will bring greater social and economic benefits.
