Comparative Research on Performance Assessment of Stormwater Management between China and America based on Landscape Performance Series (LPS)

Facing the ongoing construction of sponge city in China, how to assess its effectiveness is very important to the construction and development of the city. However, the domestic academic community is not highly concerned about the assessment of the construction results, and the current studies place more emphasis on the establishment of a mathematical assessment model, while the empirical assessment of the construction results is very lacking. In this paper, 65 cases of performance assessment of the constructed rainwater landscape, which are published by LAF, are statistically analyzed in the aspect of project type, scale, benefit ratio, benefit assessment index，assessment methods and restrictions. It will help to supplement and develop the existing research in China, and establish a small-site-scale rainwater management performance assessment system in the future which is suitable for our national conditions, so as to provide a more scientific method for the healthy development of the sponge city.
