摘要
[Objective] The aim was to review on vulnerability evaluation of grassland ecosystem under climate change.[Method] In the research,vulnerability evaluation methods of ecosystem under climate changes,at home and abroad,and the related cases and research progress in China were reviewed.In addition,the future of evaluation research was predicted.[Result] Ecosystem vulnerability to climate change is an important part of climate change research.It is necessary and urgent to improve evaluation methods and reduce uncertainty of future vulnerability evaluation to make evaluation more comprehensive and objective.Furthermore,evaluation on effects of human activity on natural ecosystem vulnerability should be highlighted.[Conclusion] The research provided reference for establishment of a new management model for ecosystem adaptability to climate and sustainable development of grasslands in northern China.
[目的]综述草原生态系统气候变化脆弱性评价的研究进展。[方法]通过综述国内外生态系统气候变化脆弱性评价方法,以及国内关于主要生态系统的气候变化脆弱性评价案例和研究进展,探讨了目前国内草原生态系统气候变化脆弱性评价存在的问题,并对其评价研究进行了展望。[结果]气候脆弱性问题是气候变化影响研究的重要内容,为最大限度减少气候变化的不利影响、利用气候变化的有利方面,未来生态系统脆弱性评价亟需改善评价方法、减少不确定性、提高气候变化脆弱性评价的全面性和客观性,并加强人类活动对自然生态系统脆弱性影响的评价研究。[结论]该研究为建立应对气候适应性管理新模式,实现我国北方草原区的生态-社会-经济的可持续发展提供了理论支撑。
