摘要
提出生态社区是一个开放的复杂生态系统,其内部环境与外部环境之间通过生态流产生关系并处于动态发展变化中.生态社区内部的主体是人和环境,并应具备生态适宜、环境健康、生活便利、景观优美、文化和谐及管理高效的特征;生态社区的动态发展变化包括空间和时间上的动态变化.通过系统功能中的物流、能流、信息流表征生态社区的空间变化,通过得分变化和弹性指标表征生态社区随时间的变化,在此基础上按照层次分析(AHP)法建立了以内部结构、系统功能、动态过程3个角度划分的生态社区评价指标体系,并参照有关研究成果给出了具体指标的参考标准值.
It was suggested that the ecological community, which was developing and changing, was an open and complex ecosystem and its inner and external environment were connected by ecology flow. The main body inside the ecological community was human and environment, and the ecological suitability, environmental health, life convenience, sight elegance, cultural harmoniousness as well as management efficiency should be achieved. The ecological community was developing and changing in time and space. The spatial changes were represented by material flow, energy flow and information flow, and the score variation and flexible indexes were used to illustrate the changes with time. According to this, an assessment index system of ecological community, which was divided by inner structure, system function, and development process, was established, and the detailed criteria index data were also given with reference to relevant studies.
