气候变化及其对生态系统的影响已成为研究热点之一,研究和了解气候变化对草原生态系统的影响是适应和应对气候变化的重要方面.本研究从土壤、植被、家畜及牧区社会经济等方面概述了气候变化对内蒙古草原自然生态系统的影响,并指出了目前研究中存在的问题,建议加强探讨草地退化动因、阐释草原碳库问题、探索放牧利用优化调控机制、积极开展草原适应性管理等方面的研究,为草原生态系统更好应对气候变化,维持系统稳定及牧区社会经济可持续发展奠定基础.
Advances in the climate change influencing grassland ecosystems in Inner Mongolia
Climate change and its impact on ecosystems have become one of the hot topics, and studing and understanding the impact of climate change on grassland ecosytems were important to adapt and respond to climate change. This study reviewed the advance in climate change influencing grassland ecosystems in Inner Mongolia from soil, vegetation, livestock and pastoral economy. And then this study proposed some issues in this field. Finally, the present study pointed out that it was necessary to strengthen understanding of grassland degradation and explain the problem of grassland carbon cycling and explore regulation of grazing optimization and implement adaptive management actively. The advices would provide some help for current and future research.
