摘　　要：若尔盖高原位于青藏高原东部边缘地带,地处阿坝藏族羌族自治州北部,黄河与长江分水岭将其划为东西两部,区内物种丰富,是青藏高原上当之无愧的"绿色明珠"。而近几十年来,由于自然因素的作用和人类活动的干扰,昔日红军经过的若尔盖草原,正沿着"湿地→草甸→退化草甸→沙化草地→沙地"模式逐渐恶化,湿地面积逐年萎缩,沙化面积增大,生物多样性受到破坏。本文主要阐述了沙化的现状、原因以及对沙化引起的生态环境问题提出了一些防治沙化和治理措施建议。Ruoergai Plateau is located in the eastern fringe of Qinghai-Tibet Plateau,located in the northern part of the Aba Tibetan Qiang Autonomous Prefecture,Yellow River and Yangtze River watershed to classify it as two part,the east and west,local species are richness.It is the welldeserved ＂green pearl＂ on Qinghai-Tibet Plateau.But in recent decades,due to the role of natural factors and interference of human activities,the Ruoergai grassland that the former Red Army came over once is a gradual deterioration along the mode of ＂ Wetlands →Meadow →Degraded meadow → sandy grassland→ Sandy＂,Wetlands is shrinking year by year,an area of increased desertification,biodiversity has been damaged.This paper describes the status of desertification,the reason and the outlook of the desertification and puts forward some proposals that can be implemented.
