摘要
全球气候变化背景下,极端干旱已被证实会对生态系统的结构和功能产生重要影响,特别是土壤与植被特征,但极端干旱对生态系统的影响程度因生态系统类型不同而存在较大差异.草地生态系统是我国最大的陆地生态系统,承载着牧区经济和生态可持续发展的重任,对降水格局变化高度敏感,因此,研究草原土壤与植被特征对极端干旱的响应,对认知自然生态系统的演变规律,预防和降低未来极端气候事件对生态环境和经济发展造成的损失具有重要意义.对草地生态系统土壤湿度、温度、养分、矿化、微生物,以及植被群落特征、植被物候、功能性状对极端干旱响应方面的研究进展进行综述,以期为研究全球气候变化条件下草地生态系统应对极端干旱气候的选择与适应提供参考.
Abstract
In the context of global climate change,extreme drought has been proven to pose significant impacts on the structure and function of ecosystems,especially on soil and vegetation characteristics.However,the impact level of extreme drought on ecosystems largely varied due to the ecosystem types.The grassland ecosystem is the largest terrestrial ecosystem in China,undertaking the prominent responsibility of economic and ecological sustainable development in pastoral areas.It is highly vulnerable to changes in precipitation patterns.Therefore,assessing the response of grassland soil and vegetation characteristics to extreme drought is of great significance for understanding the evolution laws of natural ecosystems,as well as preventing and reducing the losses resulting from future extreme climate events in the ecological environment and economic development.This paper reviews the research progress on the response of grassland ecosystems to extreme drought in the aspects of soil moisture,temperature,nutrients,mineralization and microorganisms,as well as vegetation community characteristics,vegetation phenology and functional traits,in hoping to provide references for investigating the selection and adaptation of grassland ecosystems to extreme drought climate under global climate change conditions.
