Analysis on ecological vulnerability within a region
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.
