和田河流域水量沿程变化分析研究

Analysis of water change along Hotan river basin

为缓解和田地区水资源供需矛盾,满足和田河向塔河下泄任务,本文根据和田河流域水文站实测资料,分别计算3种工况下的自上游控制站至下游肖塔站的河道水量损失率;由此分析和田河两大支流水量沿程损失的原因。并在此基础上,进一步通过相关分析得到下游肖塔站接收上游来水的临界水量、喀拉喀什河及玉龙喀什河渠首合成最小下泄流量及艾格利亚站和吐直鲁克站的最小下泄流量。其成果对和田河流域水资源开发、管理及向塔河下泄水量具有一定的参考价值。

In order to alleviate the contradiction between supply and demand of water resources in Hotan region and meet the task of sluicing from Hotan to Tahe River, According to the hydrological data in Ho- tan River basin, this paper calculated the water loss rate along the river from upstream control station to downstream Xiaota station under three working conditions and analyzed the reasons of water loss along the two major tributaries in Hotan river. Through further correlation analysis, this paper got the critical water of downstream Xiaota station receiving from upstream, synthesis minimum discharge flow of canal head of Galakashihe to Yulongkashihe River and mimimum diacharge flow of Aigeliya and Dukeluke station. The results have a certain reference value for the development and management of water resources in Hotan River basin, and discharge flow to The Tarim River.
