生态航道系统内涵及评价方法

Study on the Connotation and Evaluation Method of Ecological Waterway System

目前,航道工程已经由粗放式向生态化、多元化发展,以满足人民对美好生态环境的需求。国内对于生态航道已经有了许多明确的定义,但从统筹规划上来看,航道的生态化发展应从系统层面上考虑。从系统层面来分析生态航道的发展方向,根据当前研究进展分析了生态航道发展悖论,提出了生态航道系统的概念并分析其内涵;介绍了可用于生态航道系统评价的两种方法:生态足迹法与灰色关联法,并针对生态航道系统做出适配,分析了这两种评价方法的特点及应用,并给出了生态航道系统的若干整治措施。

At present, waterway engineering has developed from extensive to ecological and diversified to meet people′s needs for a better ecological environment. There are many clear definitions of ecological waterway in China, but from the perspective of overall planning, ecological development of waterway should be considered from the system level. This paper analyzes the development direction of ecological waterway from the system level. According to the current research progress, it analyzes the paradox of ecological waterway development, puts forward the concept of ecological waterway system and analyzes its connotation. This paper introduces two evaluation methods of ecological waterway system: ecological footprint method and grey correlation method, and makes adaptations according to the ecological waterway system. The characteristics and application of these two evaluation methods are analyzed, and several improvement measures of ecological waterway system are put forward.
