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.
