The region in the altitude f rom 4400 to 4600 meters , which is mainly covered by alpine meadow and alpine swamp meadow , is st rongly degraded by the stock raising with it s influence radius of about 24 kilometers. The influence distance perpendicular to roads is also 24 kilometers , since road const ruction accelerates human2induced destruction to vegetation. Vegetation in shade aspect is rising due to the increase in precipitation , while vegetation in sunny aspect tends to be stable or degraded because of the enhancement in sunlight . Furthermore , the vegetation coverage is influenced by the groundwater level . In near riverbed fields , where the depth of groundwater is shallow , plant s can easily grow ; while in far riverbed fields , vegetation is prone to degrade due to drainage. The radius of river influence is 24 kilometers.

海拔4400～4600m的较低海拔地带退化最强烈，主要为高寒草甸与高寒沼泽草甸受牧业影响较大；牧业影响半径为24km；道路的影响范围为24km，道路的修建加速了人类对高原植被的破坏作用；阳坡植被呈现趋于稳定和退化的趋势，阴坡植被表现为增长的趋势，降水量增加是源区植被，尤其是阴坡植被变好的重要原因，而太阳光照增强是导致阳坡干旱和植被趋于退化的潜在原因；近河床区地下水位埋深较浅，植被生长具有稳定的地下水源；在远离河床的一定区域内，地下水易于疏干，植被易于退化，河流影响范围为24km。
