近年来新疆盆地平原区域湖泊变化原因分析

ANALYSIS ON THE CHANGING CAUSES OF THE LAKES IN THE BASINS AND THE PLAINS IN XINJIANG SINCE RECENT YEARS

由绿洲及其所在荒漠盆地平原与周边山地系统共同组成的新疆地域系统 ,是我国西北干旱区的主要部分之一。由于荒漠盆地平原系统不产生径流 ,因此 ,地表水、浅层地下水和泉水、湖泊都必然地以相邻的山地系统为供给水源地。从山地进入荒漠盆地平原的河流就成为主要供给渠道。博斯腾湖、艾丁湖、艾比湖 1995年以来 ,湖水水位明显升高 ,湖水面积的不断扩大 ,从湖泊水面面积的演变过程 ,主要水源变化 ,气温略微上升 ,降水显著增多诸因素综合系统分析 ,说明在全球气候背景下 。

Consisted of the oases, desert basins, plains, and surrounding mountains, the Xinjiang territory system is one of the main arid areas in northwest China. The adjacent mountain systems are the water source areas of all the streams, shallow groundwater, springs, and lakes because runoff does not occur in the desert basin and plain systems. The rivers from the mountains to the desert basins and plains are the main water feeding channels. Since 1995s, the water level of Bosten Lake, Ayding Lake and Aiby Lake raises obviously, and their water area is continuously enlarged. Under the effect of global climate change, it is considered that the change of the lakes in Xinjiang is mainly caused by regional climate change, hydrological period varication, and human to eco environment activities according to the analysis on the change of the water sources, slightly rise of temperature, increase of precipotation, etc.
