摘要
生态脆弱性是生态系统在特定时空尺度相对于外界干扰所具有的敏感反应和自我恢复能力,是生态系统的固有属性。对现有生态脆弱性的研究区域、研究方法(包括模型模拟法、综合指数评价法、地理信息系统和空间分析技术)及研究内容等进行归纳总结,为厘清典型区域内生态脆弱性动态演变的研究现状、研究趋势提供参考。在当前生态脆弱性的研究中,暂存在理论基础、评价指标和研究方法待进一步完善,研究区域有待进一步扩展等情况。加强对生态脆弱性研究的探讨,进一步拓展研究方向和内容,提高研究质量和水平,对于保护生态环境,实现可持续发展具有重要意义。
Ecological vulnerability is the sensitive response and self-recovery ability of ecosystems relative to external disturbances at specific spatial and temporal scales,and it is an inherent attribute of ecosystems.The existing research areas,research methods including model simulation method,comprehensive index evaluation method,geographic information system and spatial analysis technology and research contents of ecological vulnerability were summarized respetivly,to provide a reference for clarifying the current research status and research trends of the dynamic evolution of ecological vulnerability in a typical region.It was found that there were situations such as insufficient theoretical foundations,insufficient consistency of evaluation indexes,the need for further improvement of research methods,and the need to expand the research areas in the current research on ecological vulnerability.Thus,it is of great importance to enhance the discussion on the study of ecological vulnerability,further expand the direction and content of research,and improve the quality and level of research to protect the ecological environment and achieve sustainable development.
