Such institutional and financial support have allowed Xi'xian to implement a Pilot Construction Plan and Three-year Action Plan for Adapting to Climate Change. In 2020, Xixian formed an urban ecology system including 21 m2 of green space per capita. The old cities' underground drainage pipe network has been replaced by sponge designs such as green corridors, grass ditches, water storage gardens and recessed green spaces. The 10 waterlogging prone points in Xi'xian New Area have been eliminated and the green area has alleviated urban heat, with average temperature about 1℃ lower than the neighbouring densely populated mega-cities of Xi'an and Xianyang. Groundwater in the New Area has also risen by 3.43 m compared with 2015.
