基于景观绩效系列(LPS)的中美雨水管理绩效评价比较研究

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

面对中国如火如荼的海绵城市建设,如何评价其成效对城市的建设和发展至关重要。但国内学术界目前对其建设成果评价的关注度并不高,且研究侧重数学评价模型的建立,对建设成果的实证评价较少。本文以美国风景园林基金会发布的65个已建成的、雨水景观绩效评价案例为研究对象,对其项目类型、规模、效益组成比率、效益评价指标、评价方法及限制等进行了统计和分析。本研究将有助于补充和发展国内现有研究,在未来建立场地尺度的、适应于我国国情的雨水管理绩效评价体系,为海绵城市的健康发展提供更为科学的方法和保障。

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.
