摘　　要：草地退化是过度放牧、开垦土地等人为活动及不利自然因素影响下草地生态系统逆行演替的一种过程。从植被和土壤两个方面论述了川西北草地的退化现状,并分别从自然和社会经济的角度分析了草地退化的驱动力,针对草地退化的原因提出相关的防治对策,以促进川西北草地畜牧业的可持续发展。Grassland degradation was described as a process of retrogressive succession of grassland ecosystem resulted from human activities （over grazing,reclaim）and unfavorable natural conditions. The grassland degradation status in northwest Sichuan was discussed based on vegetation and soil. The driving forces of grassland degradation were analyzed from natural and social aspects. Strategies for preventing rangeland from degradation and for sustainable development in rangeland area were recommended based on these analysis.
