摘　　要：草原退化是自然因素和人为因素综合作用的结果。而同全国其他草地退化相比,西藏天然草地退化的原因既有共性,也有独特的原因。全球气候变暖、脆弱的生态环境、严重的草地鼠虫害、草地建设滞后、投入不足等问题一致是影响西藏天然草场保护与建设的主要原因。Grassland degradation is the result of the combined effects of natural and human factors.Compared with the degradation of other grasslands across the country,the reasons for the degradation of natural grasslands in Tibet are both common and unique.In terms of commonality,serious grassland rodent and insect pests,delayed grassland construction,and insufficient investment are the main reasons affecting the protection and construction of natural grasslands in Tibet.
