解决城市生态环境问题的生态基础设施途径

对待城市生态环境问题,该研究放弃了就事论事的单一分析和工程途径,而是提出解决生态环境问题必须依靠综合、系统的途径,即:通过建立生态基础设施来整合相关的生态过程与景观结构。以山东东营市为例,论文提出从3个步骤来实现综合问题的综合解决:①通过德尔菲法实现问题的综合与多目标的确定;②通过建立生态基础设施,综合地解决以水为核心的多个生态环境问题,实现多个目标;③评价生态基础设施对解决多目标问题的作用和效益,并为修正方案提供依据。文章在区域、城市和场地3个尺度上,提出解决东营市生态环境问题的生态基础设施实施战略。

Ecological Infrastructure as a Synthetic Solution to Urban Environmental Problems

The speedy urbanization processes in China caused various ecological and environmental problems,and the degradation of water associated environment is one of the biggest issues.These problems were more than often resulted from"small decisions" and single minded engineering approaches in dealing with urban environment.It is highly recommended that a multifunctional and synthetic approach is required in order to solve the ecological and environmental problems in Chinese cities.Using the city Dongying as a case,this paper proposes a three-step approach to develop synthetic solutions to the ecological and environmental problems:(1)The synthesis of problems and definition of goals using Delphi method;(2)the development of strategic landscape structures which are integrated into the ecological infrastructure to solve the problems with multifunctional goals; and(3)the impact analysis regarding the proposed ecological infrastructure.A number of landscape strategies were proposed.
