Abstract: Under the background of pilot construction of sponge city in Chongqing, few research have been done to study the strategies of constructing the stormwater management landscape system in mountainous urban parks based on the performance of hydrological cost-effectiveness. This research focuses on six typical cases of hilltop and hillside landform conditions, providing the low-, medium- and high-levels of stormwater management landscape system strategies. It assesses the performances of hydrological control, life cycle cost and hydrological cost effectiveness of various strategies. The result shows that the low-level strategy could be used based on the optimal hydrological cost effectiveness performance. The medium level strategy could be adopted when it needs to meet 80%-85% of the total annual runoff control rate of the parks. The high-level strategy could be applied for the gentle slope case under sufficient cost investment to control the extreme rainfall events (as 10-or-30-year return period). This research provides resilient strategies for the design of the stormwater management landscape system in hilltop and hillside urban parks in Chongqing and subtropical monsoon humid climate areas.
