Tongnan Dafosi Wetland Park is located on both sides of Fu River flowing through the central area of Chongqing Tongnan District. Its south side is right next to the national tourist spot – the Great Buddha Temple (Dafosi). Due to the increasing frequency and severity of extreme rainstorms, the area is prone to floods. To build an urban wetland park that is adaptive to floods, designers retained the original wetland environment along the river channel and set up pedestrian corridors to enable citizens’ close contact with wetland nature. [1, 3] This project excavates two important cultural elements of Tongnan: 1) the shipping culture with a long history; and 2) the Buddhist culture based on the Great Buddha Temple. [1]

Project objectives

The Tongnan Dafosi Wetland Park aimed to innovatively combine wetland protection with urban park development, whilst promoting local culture and building local identity. It uses flood-adaptive design to lower the cost of maintenance while creating spaces for citizens to connect with nature and to conduct various activities. [1, 3] The specific goals of the project include [1]: - Flexible design to be adaptive to floods - Restore habitats for wetland flora and fauna - Increase habitat diversity - Create a vibrant urban living room providing rich experience for the citizens - Preserve local cultural heritage of the shipping and the Buddhist culture, in designing and building the wetland park as well as the installations within the park.

Implementation activities

The main implementation activities of this project include: - Flexible design to be adaptive to floods: maintaining the geographical features of the site to the maximum and use minimum intervention measures; build pedestrian walkways and cycling paths, enabling citizens’ close contacts to wetlands; and allocate the main activity space and facilities in areas that are not prone to be submerged so as to reduce maintenance cost. [1, 2] - Install water pipelines that can, on one hand, direct water from the Fu River into the various wetlands within the Park, supporting the ecosystems, and on the other hand, can water the plants directly during drought season [2] - Restore habitats for wetland flora and fauna: build ecological slope protection, restore the original maple forests and grass vegetation in the islands located in the middle of the river, and increase tree islands to provide habitat for birds. [1] - Increase plant diversity: create an aquatic planting area of about 8,000 square meters for lotus flowers, and create a ground cover planting area of 170,000 square meters for about 50 types of plants such as Jacaranda, Taxodium ascendens, Salix alba, Pink grass, Lotus alba and Fruits. [3] - Create a vibrant urban living room: the park is designed into different functional zones, including sprots and leisure area, urban balcony area, Dafosi Wetland area, etc., which is also equipped with a public bath and several meditation spaces, providing rich experience for the citizens.
