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。
Climate change is the biggest stress factor that today’s terrestrial ecosystems face. Studying the prevention and control of land degradation in dryland ecosystems under the background of climate change, enhancing the capability of mitigating and adapting to climate change, and gradually restoring the integrated production potential originally owned by land ecosystems are important topics to be solved urgently. The paper analyzes the impact of climate change on land degradation in arid ecosystems. From the perspective of integrated ecosystem management, this paper discusses ways to protect and restore forests, grasslands and farmland ecosystems so as to enhance their ability to cope with climate change and improve people’s livelihood. Provide a new idea for the prevention and control of land degradation and the sustainable management of arid ecosystems in the context of climate change.
