Abstrakt: To study the characteristics of sponge city construction under different background and urban construction characteristics, choosing No. 5 drainage area (urban renewal of old industrial districts) and No. 15 drainage area ( comprehensive improvement of old residential and industrial area) in Guangming District, Xinhe water basin in Pingshan District (inland area), and Dameisha area in Yantian District ( coastal area) as typical sponge city monitoring and evaluation areas, we summarize and compare the phase achievements of monitoring and evaluation in four areas based on volume capture ratio of annual rainfall. The volume capture ratios of annual rainfall in the four areas have reached the target set by the upper planning. Moreover, the characteristics of urban construction and the regulation and storage performance of water system are correlated with the construction effect of sponge city in the four areas. We propose that the construction of sponge city should not only strictly focus on compliance construction, but also strengthen the balance and coordination of contiguity effect under the planning framework. Focusing on the urban rainwater issues, we deeply identify background resources and high-efficiency sponge bearing space of the area, pay attention to the comprehensive planning, and emphasize the internal co-ordination and integration of resources to solve practical problems systematically at district level. We emphasize the systematization and regional effect of sponge city, promote the overall efficiency of reaching the standard, and improve the contiguous effect and display degree of sponge city. We suggest to guide the sponge city construction station to realize the contiguous effect from the perspective of system reaching the standard at the district level. [ABSTRACT FROM AUTHOR]
