Abstract藏北高寒草地系统生态脆弱且区位重要,草地退化和沙化的治理是目前学者们重点关注的领域之一。本文采用遥感解译、模型模拟、地面取样验证等相结合的方法,分析了藏北高寒草地生态系统退化的现状、趋势和原因,以实验为基础,总结了退化草地恢复的几种重要模式。数据分析表明:藏北羌塘高原轻度退化草地占62.0%,中度和重度退化草地占15.1%,1991年以来,退化面积快速增加,2000年以来重度退化面积增加趋势明显。藏北西部的草地轻度退化可能由气候暖千化所引起,而中部、东部的重度退化主要由超载过牧引起。总结出轻度退化草地的“封育”、中度退化草地的“施肥+封育”、重度退化草地的“补播+施肥+封育”三种草地恢复模式。提出了退化草地恢复和保护的间接途径“南草北上”生态工程的战略构想。
