摘要
利用且末1958—2005年的降水、气温、径流量、卫星遥感等资料,分析了车尔臣河下游生态环境变化的成因。指出全球气候变暖使得山区冰川融解加快,车尔臣河径流量增加有利于车尔臣河下游生态恢复;人类活动的增加如修防渗渠、人工造林、人工增雨、围湖育苇、人工输水等活动改变了小气候,改善了绿洲生态环境,是车尔臣河下游生态环境恢复的主要原因。
Make use of the data such as precipitation, temperature, runoff, satellite remote sensing etc. in 1958--2005, this paper analyzed the causes of recovering ecological environment in Che＇erchen River downstream, the results indicated that global climate warming speeded up to melt mountain area glacier, the increased runoff amount of Che＇erchen River was favorable for the restoring ecological environment in its downstream; and human activity such as building seepage control canal, artificial afforestation, artificial precipitation enhancement, artificial cultivating reed, artificial to input water etc. changed the microclimate and improved the ecological environment in the oasis. These are the main reason of resuming the ecological environment in Che＇erchen River downstream.
