Research Progress in Stormwater Storage Benefit of Urban Green Spaces
In order to systematically understand the research progress and development trend in stormwater storage benefit of urban green spaces,this paper reviews the relevant research on storm water storage benefit and capacity of urban green space at home and abroad,summarizes the influence of stormwater redistribution process on stormwater storage benefit,and reveals the influencing factors to stormwater storage benefit in different phases of runoff formation.The results indicate that in the process of canopy interception,stormwater storage benefit is affected by many factors such as plant species,leaf characteristics and pruning shape,and the canopy water storage capacity of various vegetation is much different;In the process of stormwater infiltration,green space configuration and soil characteristics are the main factors affecting the benefit of stormwater storage;In the process of surface runoff formation,there is a significant correlation between the landscape pattern of green space and the runoff,and the rational construction of urban green space landscape pattern can realize the subjective regulation of urban hydrological process.There is a lack of small-scale analysis on the benefit of stormwater storage for urban green spaces,and few studies have been conducted for the interactions between various factors.At the end,the research directions are discussed,and exploring and improving the stormwater management mode suitable for China and establishing a systematic and scientific theory and evaluation index system are recognized as the important directions.
