摘要
文章从城市河流水生态系统服务供需匹配的视角切入,通过AHP法与yaahp法构建供需评价体系。采取外业调研、问卷调查与专家打分等方式对评价指标进行赋值,通过对河流整体与河道单元的供给水平与需求程度的评价分析河流水生态系统服务供需匹配特征;在探讨影响供需失衡因素的基础上,从调节、支持、文化3种服务类型入手,针对河流整体与河道单元提出了供需匹配的规划设计策略,以达到城市河流景观提升和可持续发展的目标。该研究可为城市河流景观规划与设计提供借鉴。
This paper constructs the water ecosystem services supply and demand evaluation system from the perspective of supply-demand matching by using AHP method and yaahp method,and adopts field survey,questionnaire survey and expert scoring to give weighed value to the evaluation index.With the system,the supply level and demand degree of the whole river and river units are evaluated,and the matching characteristics of river ecosystem services supply and demand are analyzed.Based on the discussion of the factors leading to the supply and demand imbalance,the paper puts forward the planning and design strategy for supply-demand matching of the whole river and river units in terms of the regulation,supportive and culture services,so as to achieve the goals of improving urban river landscape and promoting sustainable development.This study would provide references for urban river landscape planning and design.
