摘要
在对杞麓湖近20年来的水生态、流域社会经济、服务功能、生态灾变等进行调查研究的基础上,以20世纪70年代末80年代初杞麓湖的生态安全状况为背景,运用评估模型对杞麓湖1994—2013年湖泊生态安全状况进行了综合评估。结果表明:杞麓湖2013年生态安全状态已处于第5级、"很不安全"的黑色预警状态;生态安全程度近20多年处于较差状况,安全分级多为"一般"和"不安全"。
Based on investigating the aquatic ecosystem, social and economic development, ecosystem service and ecological catastrophe of Qilu Lake in the last 20 years, the state of ecological safety of Qilu Lake during 1994 - 2013 has been evaluated synthetically using the evaluation model by taking the state of ecological safety of Qilu Lake in the 1980s as the background value. The evaluation results showed that the state of ecological safety of Qilu Lake was at level 5 in 2013, which indicated a dangerous state. In the past 20 years, the states of ecological safety were inferior and the grade of which mainly was general or unsafe.
