Nansha area has the typical characteristics of subtropical maritime monsoon climate. Due to the influence of tropical weather system, the rainfall is mainly dominated by heavy typhoon rain, which is prone to waterlogging caused by the tide crest of the offshore sea. Under the condition of high water level roof support in the bearing and drainage area, a large amount of internal flood water cannot be discharged in time, which often leads to serious flood disaster.
Under this background, the city park as an important urban public space of urban rain flood regulation, based on the rain flood management measures at home and abroad related patterns in the field of finishing, research and summarize, generalize the park landscape design process into the rain flood design method of system management, promote the sustainable development of city, improve the rain flood control system in the event of a rise in sea level of flexibility.

Through land replacement, the design remolded the height difference of the site to strengthen the natural storage capacity of the site. The objective is to increase building density at higher levels and reduce it at lower levels, freeing up low-lying areas to provide space to support flood management strategies. Coastal ecosystem protection, wildlife and Marine habitat restoration, green space resilience, damaged wetlands and mangroves restoration, coastal resilience, and ultimately a more comprehensive and diverse response to flooding.
