【摘要】：人类在影响地球的同时,因人类活动引起的全球变化成为了国际上热点研究内容,由此引发的生态安全问题也引起各界学者的高度重视,而三峡库区作为一个重点研究课题,其生态安全也受到了极大的关注。本文以重庆三峡库区为研究对象,在对其生态安全进行综合评价的基础上,找出三峡库区生态安全后续发展的瓶颈及存在的问题,并从自然、社会、经济3个方面确定其胁迫因子。以Vensim软件为基础平台,建立三峡库区生态安全后续发展的系统动力学模型,在模型检验通过后,对三峡库区生态安全的后续发展进行动态模拟。基于胁迫因子的反馈关系和模拟结果,分析三峡库区生态安全后续发展的胁迫机理,从而为进行三峡库区生态安全后续发展的预警评价奠定基础。
[Abstract]:While human beings influence the earth, the global change caused by human activities has become a hot topic in the world, and the ecological security problems caused by it have also attracted great attention from scholars from all walks of life, while the three Gorges Reservoir area is a key research topic. Its ecological security has also received great attention. This paper takes the three Gorges Reservoir area of Chongqing as the research object, on the basis of comprehensive evaluation of its ecological security, finds out the bottleneck and existing problems of the following development of ecological security in the three Gorges Reservoir area, and from the natural, social, Three aspects of the economy determined its coercive factors. Based on Vensim software, the system dynamics model of ecological security follow-up development in the three Gorges reservoir area is established. After the model is verified, the following development of ecological security in the three Gorges reservoir area is simulated dynamically. Based on the feedback relationship of stress factors and simulation results, this paper analyzes the stress mechanism of ecological security in the three Gorges Reservoir area, which lays a foundation for the early warning evaluation of ecological security development in the three Gorges Reservoir area.
