【摘要】：车尔臣河是塔里木盆地东南部最大的一条河流,主要依靠雪冰融水和地下水补给。上游山区由于有库木库里盆地和吐拉盆地对径流的调节,水量各季节变化比较平稳,特别是春季占全年径流量的29%,是新疆春季径流所占比例最大的河流之一,春灌基本不缺水。农业灌溉和生态用水各占水资源总量的一半。绿洲虽不断扩大,但中游地下水位仍较高,植被未发生明显退化,同时还向台特玛湖输送一定水量。因此,对车尔臣河水资源利用应保持原生态状况,不宜人工修建大型水利工程。由于车尔臣河出山口有巨大的洪积冲积扇,渗漏量占出山口径流量约30%,是一个比较理想的天然地下水库,所以今后经济发展用水应以开发地下水为主。
[Abstract]:The Chellchen River is the largest river in the southeast of the Tarim Basin, which mainly depends on snow-ice melting water and groundwater recharge. Due to the regulation of runoff by the Kumukuli basin and the Tula basin, the water volume varies steadily in each season in the upper mountain area. In particular, spring accounts for 29 percent of the annual runoff and is one of the largest rivers in Xinjiang in spring runoff. Spring irrigation basically does not lack water. Agricultural irrigation and ecological water use each account for half of the total water resources. Oasis continues to expand. However, the groundwater level in the middle reaches is still high, the vegetation has not degenerated obviously, and a certain amount of water is transported to Lake Taitema at the same time. Therefore, the utilization of water resources in the Chellchen River should be maintained in the original ecological condition. It is not advisable to build a large water conservancy project manually. Because of the huge alluvial fan at the exit of the Cherchen River, the leakage accounts for about 30 percent of the runoff at the pass, so it is an ideal natural underground reservoir. Therefore, the future economic development of water should be based on the development of groundwater.
