Tiger Hill Wetland Park is an important part of Suzhou's "Four Corners of Landscape" spatial layout, and is also an important carrier for Suzhou to accelerate the construction of ecological civilization. The park is planned to use 12.04 square kilometers of land, including 6.43 square kilometers in Xiangcheng District and 5.61 square kilometers in Gusu District. In order to build the "urban green lung" in northern Suzhou, the city planning department revised the 2006 edition of the park planning plan and solicited detailed planning plans from around the world, striving to highlight the cultural charm and unique features of the Jiangnan water town.
