摘要
为明确高原淡水湖泊的生态安全状况及其演变趋势,以喀纳斯湖为例,基于驱动力、压力、状态和响应组成的生态安全综合评估指标体系,应用多级灰色关联评估理论计算了流域生态安全指数。结果表明,2008~2012年生态安全指数呈下降趋势,通过实施流域产业结构调整、污染源控制、流域土地资源调控、湖泊生态保育等工程措施,缓解了安全指数下降趋势,保证了喀纳斯湖生态环境处于安全状态。
To clarify the ecological security situation and its evolution trend of the freshwater lake in plateau, based on the comprehensive evaluation index system of ecological security which is composed of driving force, pressure, state and response, the ecological safety index in Kanas Lake was calculated by using multi-level gray relational assessment the- ory. The results show that the ecological safety index appears downward trend during 2008 to 2012; through implementa- tion of project measures such as watershed industrial reconstruction, pollution source control, watershed land resources regulation, lake ecological conservation, the downward trend of safety index is relieved and it ensures the safety state of ecological environment of Kanas Lake.
