乌鲁瓦提水库是国家“九五”重点工程,承担着和田河灌区供水和电力保障,以及为塔里木河干流输水维持整个流域生态安全的任务。回顾了2003年投入运行情况,总结了供水和发电效益,进一步分析了2007年向塔河输水显著减少的可能原因,并提出了兼顾防洪与生态效益的几项建议。 The Uluwatti Reservoir is a national key project of the “95th Five-Year Plan” and undertakes water supply and power supply to the Hetian River Irrigation District as well as the task of maintaining the ecological safety of the entire river basin by delivering water to the mainstream of the Tarim River. After reviewing the operation status in 2003, summarized the benefits of water supply and power generation, further analyzed the possible reasons for the significant decrease of water conveyance to Tahe River in 2007, and put forward several proposals that take both flood prevention and ecological benefits into consideration.
