摘要
脆弱性研究领域不断从自然生态系统向社会自然复合系统扩展,从社会生态系统视角动态化和人文化地研究脆弱性已成为趋势。湖泊流域是多层级的复合的社会生态系统,从流域角度、社会生态系统层面、体制机制维度,综合分析社会生态系统脆弱性的驱动机制,对系统治理和源头治理湖泊流域具有重大意义。文章以滇池为例,将"压力—状态—响应"模型和"暴露度—敏感性—恢复力"模型结合,构建脆弱性分析框架和评价模型,探寻湖泊流域社会生态系统脆弱性时空演变规律和脆弱性驱动机制,提出了湖泊流域脆弱性调控和区域可持续发展的思路。
This article, taking the Dianchi lake as an example, combining the ＂Pressure-State-Response＂ mod- el and ＂Exposure - Sensitivity - Resilience＂ model, from the point of view of social ecological system, build social ecosystem vulnerability analysis framework, exploring the space-time evolution of the vulnerability of the Dianchi lake watershed, revealing the driving mechanism of vulnerability. The author holds that： 1） The Dianchi lake basin is the origins and centor of the Kunming city in term of vulnerability development, whose vulnerable area is expanding, vulnerable degree increasing; 2） The watershed keep staying in the high-risk stage of vulnerability, easy to change the steady state of the system; 3）Sensitivity and responsibility to disas- ter is weakening in the whole system during the peroid from 1990 to 2010a; 4）Special geological and geo- graphical environment, limited environmental capacity make the congenital basement for the vulnunerbilty; 5）Excessive concentration of function role serving the region, leading to intensified human activity, complex pollution sources, destrueed the naturial landscape, deteriorated and made damage to the human-enviroment relations; 6）Unreasonable land use made the landscape pattern destroyed, ecological conection between parts of the system interrupted, ecological service function of the system weak or even lost totally; 7） Weak envi- ronmental consciousness of the users in the watershed, low management efficiency of the authority add to the vulnurbility of the system; 8） Low-end industrial structure, low-efficiency production hinder the cultiva- tion of the responsibility of the system.
