摘要：

草地是陆地生态系统中最重要的生态系统之一，在维持陆地碳平衡，减缓气候变化中起着重要作用。笔者论述了草地退化的驱动因子及草地退化中的碳变化效应。从草地生态系统中植物生长和土壤性质2个方面分析了土壤固碳潜力与机制，并结合国内外研究动态，提出未来草地的主要研究方向。

Abstract:

Grassland is the one of the most important terrestrial ecosystem and plays an important role in the carbon budget. The driving factors of degraded grassland and carbon changes were discussed. The key driving factors and dynamics of carbon of degraded grassland were discussed. The carbon sequestration potential and mechanism of grassland ecosystems were discussed based on grass and soil properties. And some suggestions were given for researching on the carbon dynamics of grassland ecosystems.
