《Chinese Geographical Science》杂志刊登“干旱地区水分输移特征及其对环境的影响”

作者:Xin Li,Yu-dong Song,Fu-hua Nian

关键词:干旱地区;水分输移;人类活动;环境

摘要:水流在山区形成,在流入平原地区的过程中不断蒸发和渗透,最终消失在沙漠中或流入下游的湖中,这就是干旱地区水量平衡的特点。但是,在人类活动的影响下,中国新疆水资源的分布和输移已经发生了改变。人类活动的影响发生在较短的时间和区域内,特别是在以水作为环境主要因素的干旱地区。绿洲内的水量有所增加,绿洲外或河湖下游的水量则有所减少。通过改变水循环及其分布,人类活动已对环境产生了各种正面和负面的影响。在人类活动的影响下,新疆的绿洲不断扩大,同时,一些湖泊的荒漠化严重,自然植被减少,绿洲外的自然环境也在衰退。

Abstract: The characteristics of water balance in arid regions is that the streams are formed in mountain area and continuously evaporates and infiltrates in the process of flowing to plain area, streams finally disappear in the desert or flow into the lakes, which are the low reaches of the rivers. But the distribution and transformation of water in Xinjiang, China have changed under the influences of human activities. The influences of human activities take place in a short time and regionally, especially in arid land where water is the key factor of environment. Water inside of oasis has increased, and water out of oasis or at the lower reaches of the river has decreased. Human activities have caused the environment changes in both positive and negative aspects by changing the circulation and distribution of water. Under the influence of human activities, oases in Xinjiang have expanded, meanwhile some lakes have contracted desertification is serious, natural vegetation has declined and natural environment out of oasis has degenrated.
