Climate Change in Zoige Plateau and Adjacent Zone and Its Impact on Wetland Environment
2008
We collected and analyzed all climatic data at 8 meteorlogical stations in Zoige plateau and adjacent zone.The result show that the annual mean temperature was gradually ascending at all these zones,the ascending extent was 0.2284℃ per year in Zoige plateau.Every season mean temperature simultaneity was gradually ascending,and we find winter ascend temperature was most obvious.We studied annual occurring time of 0℃ and 3℃ aim at pasture,and we find the time distant shorten,the time occurring 0℃ was delayed.The entire growth time of pasture was extend,and the accumulate temperature was increased during growth time of pasture.Our investigate find it was very severity that pasture was gradual turning to desert.By the inspect compare 1999 with 2004,the area of desert increase 4307.1hm2,the increase rate was 73.46 percent.At one time many lakes are gradual shrinking.
