塔什库尔干河流域是叶尔羌河中上游的主要支流之一,流域主要为高中山区,平均海拔4 630m,高山区终年积雪,冰川发育.降水量的年内分配不均匀,暖季汛期降水量大而集中.塔什库尔干河流域发育有现代冰川862.45 km2,流域冰川覆盖率为8.64%.河流径流过程一般为双峰型,由春季的融雪径流和夏季的冰川融水径流形成,冰川融水占年径流的45%~55%,为典型的冰雪融水河流.塔什库尔干河的水能资源非常丰富,河道末段81 km的河道干流上有天然落差达1 020 m,在此河段上共规划了7个梯级水电站,总装机55.8×104kW,目前尚有40.8×104kW水电装机待开发.开展塔什库尔干河水能资源的开发利用,对增加能源供应安全、改善能源结构、保障能源安全具有非常重要的意义.
The Shishkungan River Basin is one of the main tributaries of the Yarkant River middle and upper reaches, and the basin is mainly a high school mountain area with an average elevation of 4 630m. There is snow accumulation and glacier development in the high mountainous area all year round, with uneven distribution of precipitation during the year and large and concentrated precipitation in the warm season. There are 862.45 km2 of modern glaciers in the Taxkorgan basin and 8.64% of the glaciers in the basin.The runoff of the rivers is generally bimodal, formed by snowmelt runoff in spring and glacial melt runoff in summer, accounting for 45% of the annual runoff, ~ 55%, which is a typical ice-snow melting river.Taskurgan River is rich in water energy resources, with a natural drop of 1 020 m in the 81 km river channel in the last section of the river channel, and a total of 7 cascade hydropower stations , With a total installed capacity of 55.8 × 104kW, there are still 40.8 × 104kW hydropower installed capacity to be developed.To carry out the development and utilization of hydropower resources in the Taxkorgan River is of great significance for increasing energy supply security, improving energy structure and ensuring energy security.
