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。
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 muhi-objective and muhilevel 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.
