塔里木河中游水资源及其生态环境影响分析

Analysis of Water Resource and it′s Impact on Ecological Environment in the Middle Reaches of Tarim River

借助塔里木河中游英巴扎站和卡拉站1961-2005年径流量数据和其他相关统计资料,对45年来塔里木河中游径流量、损耗量进行时序分析,分别得到45年来中游年径流量及其趋势、中游耗水量及趋势、中游耗水量与径流量相关关系,并对其进行了分析,得出自20世纪60年代以来,塔河上游进入中游的水量减少,同时中游耗水量不断增加,至使下泄到下游的水量越来越少,从而引起下游严重的生态环境问题.研究结果表明,加强中游段水资源的管理对流域生态系统的恢复和健康发展至关重要.

Based on runoff data in Yingbaza and Kala hydrological stations and other related data from 1961 to 2005 ,the runoff and consumption quantity in the Middle Reaches of Tarim River are analyzed by time order during 45 years. The runoff quantity diversification and trend, consumption and trend, the relation of runoff quantity and consumption during 45 years are obtained and analyzed. Analysis shows that the upriver runoff decreases and that in middle reaches also decreases, but at the same time the consumption in middle reaches increases and the runoff in lower reaches becomes less and less, which brings bad ecological environment issue. So we draw the conclusion that to resume ecosystem and develop healthy in Tarim River , it is important to manage effective water resource in the Middle Reaches of Tarim River.
