气候变化背景下干旱生态系统土地退化防治

气候变化是当今全球陆地生态系统所面临的最大胁迫因素。探讨气候变化背景下干旱生态系统土地退化防治, 增强减缓和适应气候变化的能力, 逐步恢复土地生态系统原先所具有的综合生产潜力, 是亟待解决的重要课题。文中分析了气候变化对干旱生态系统土地退化的影响, 从综合生态系统管理的视角, 探讨了保护与恢复森林、草地、农田生态系统以增强应对气候变化的能力以及改善民生的途径, 以期为全球气候变化背景下土地退化防治和干旱生态系统可持续管理提供新的思路。

Land Degradation Control in Arid Ecosystem Under Climate Change Context

Climate change is the largest stress factor challenging global territorial ecosystem. The discussion on land degradation control in arid ecosystem under the context of climate change for increasing the capacity to mitigate and adapt to the climate change and gradually restoring the integrated production potential originally possessed by land ecosystem is a pressing issue to address. The paper analyzed the effect of climate change on land degradation in arid ecosystem, and described the protection and rehabilitation of forest, grassland and farmland ecosystems, the enhancement of the response to climate change and the improvement of people's livelihood from the viewpoint of integrated ecosystem management. This study is expected to offer a new concept for land degradation control and sustainable management of arid ecosystem in the context of global climate change.
