阿克苏河流域无站控制区地表水资源及可利用量评价

The Surface Water Resources and Its Available in the Non-Controlled Area in the Aksu River Basin

阿克苏河是"四源一干"中最大的源流,多年平均地表径流总量为80.6×108m3,入塔里木河水量34.2×108m3,占阿拉尔站以上3条源流输水量的73.5%,对塔里木河的形成、发展、演变和生态环境起着决定作用.无站控制区调查面积7 110 km2,占流域总面积的14.2%.2005—2007年对中国境内阿克苏河无站控制区主要19条河(沟)洪水水量、洪水沟基流和17条泉水水量野外调查计算,阿克苏河流域无站控制区间地表水资源总量为6.68×108m3.其中,洪水沟总洪量0.6050×108m3,洪水沟基流总量2.0569×108m3,泉水天然补给量4.0185×108m3.在6.68×108m3的地表水资源总量中,可利用量为3.2×108m3.

The Aksu River is the largest tributary of the Tarim River,is the exclusive river water conveyance perennially to the Tarim River.The annual average runoff is 80.6×108 m3,and contributed about 73.5% of the total amount of the Tarim River.The Aksu River plays an important role in forming,development and evolution of the Tarim River Basin.The area without hydrological station survey is 7 110 km2,accounting for 14.2% of the total area of watershed.The field survey of the flood,base flow of flood channel of the main 19 small rivers（channels,brooklets and rivulets） and 17 springs in non-controlled area in the Aksu River Basin during the period of 2005 to 2007 showed the total surface water resources is 6.68×108 m3,in which the flood is 0.6050×108 m3,the base flow of flood channel is 2.0569×108 m3,the supply by natural spring is 4.0185×108 m3.The available water is 3.2×108 m3.
