The world is currently undergoing unprecedented urbanization which has contributed to replacement of the existing natural green spaces with impervious surfaces. The reduction and fragmentation of green infrastructure can result in environmental challenges locally, regionally and beyond, due to biochemical and physical changes to ecological systems. Specifically, the rapid increase in area of impervious surfaces reduces rainwater interception, storage and infiltration, resulting in a concomitant increase in runoff generation in urban catchments. Therefore, nature-based solutions, denoted as green infrastructure, have been widely recommended to reduce stormwater runoff, improve water quality, cool urban air temperature, provide ecosystem sustainability and so on. The development of green infrastructure has experienced three stages:early germination, initial formation, and rapid development. The research mainly focuses on the regionally ecological security in the macro scale, promotes the sustainable development of the city in the meso scale, and solves the community ecological environment problems in the micro scale. At present, the research content of green infrastructure includes two aspects:ecological function and social function, mainly concentrated on the regulation of rainfall runoff, reduction of non-point source pollution, regulation of regional microclimate, residents' health and well-being, and spatial distribution equity. The supply and demand structure of green infrastructure is also the key factor effecting the service quality of green infrastructure. Generally, the service function of green infrastructure will increase with the increase of its scale, but the imbalance of supply and demand allocation of local green infrastructure often leads to the problem of local service surplus or shortage. At present, the development of green infrastructure is difficult to meet the needs of China's rapid urbanization. The quantitative evaluation of green infrastructure function is insufficient, and the research on supply and demand structure is not deep enough. Future research should strengthen the cross integration with related disciplines, improve the measurement and evaluation methods of green infrastructure function, and combine green infrastructure construction with spatial planning, in order to provide support for regional sustainable development and national ecological civilization construction.
