Evaluation indicators system for regional ecosystem health
-
摘要: 探讨了区域生态系统健康指标选择原则。从区域的河流和陆地两方面确定指标体系,根据生态系统层次性,采用多目标多层次模糊优选模型。以广东省为例,在广东省分生态小区的基础上,对各区的生态环境进行了评价与比较排序,通过综合优属度给出了生态系统健康状态。Abstract: The selection principles for regional ecosystem health index are discussed. Based on the regional rivers and the landscape,the indicators are established. According to the ecosystem hierarchy,the multi-objective and multilevel fuzzy optimization model is selected to evaluate the ecosystem health. For instance,in Guangdong province,the ecological zone are partitioned,assessed and sorted based on the synthesized attributes.
