摘要
目前,已有很多研究致力于讨论保护规划中整合保护效益和经济成本的重要性。为丰富解决该问题的思路,从系统保护规划理念出发,应用MARXAN模型软件对长江流域两栖爬行类生物多样性保护优先区进行了选择和评价。研究中共选择两栖物种54个,爬行物种73个作为指示物种,并按濒危性和特有性划分为5个类型。综合考虑每个类型的特定保护目标,以县域人均GDP为相对保护成本,探讨如何选择达到保护目标的最低经济成本区域。通过运算每个规划单元的不可替代性,共选定保护优先区9个,包括121个县(市、民族自治县)。建议以9个保护热点区为基础,率先建立各区域内保护网络,同时在已建保护区日常巡护中加入两栖爬行动物巡护内容。
There is considerable features and economic cost in t discussion about the relative importance of the integration of biodiversity he conservation planning. Trying to overcome the problem, we identified priority areas for amphibian and reptile biodiversity within the Yangtze Basin using the idea of Systematic Conservation Plan. We applied the conservation planning tool, MARXAN, to summarize 57 amphibian and 85 reptile values which were formulated by whether they are endangered or domestic species as five types. The GDP of the counties in research area have been used to simulate the conservation cost for the identification of the areas with high biodiversity representation and low economic cost. In accordance with iterative computing,we obtained 9 conservation priority areas including 121 counties. Our suggestion is to establish conservation network within every priority area we picked out. Meanwhile, the content about amphibians and reptiles should be highlighted in daily patrol.
