基于效益-成本的绿色基础设施规模设计
Scale design of green infrastructure based on benefit-cost analysis
摘要
Abstract
A part of the campus of Xi'an University of Architecture and Technology was chosen to study how to determine the scale of green infrastructure based on the benefit-cost analysis.Scale design of green infrastructure is according to the dual goal of benefit and cost .After improving the rainfall reappearance period , we try to maximize the efficiency of green infrastructure with the lowest construction cost .The NSGA-Ⅱ algorithm was used to find the Pareto front of the benefit-cost relationship of green infrastructure scale.The results show that, with the increase of the rainwater retention ratio, the construction cost of green infrastructure will increase slowly in a certain range.Beyond this range, the increase of the rainwater retention ratio will lead to a sharp increase in the construction cost.关键词
