新变化形势下克拉玛依市地表水资源可利用量的估算

The Estimation of Available Quantity of Surface Water Resources in Karamay under the Condition of New Changes

为克拉玛依市在新的变化形势下更好的应对水资源短缺问题,并及早谋划相应的应对措施,对工农业、经济和社会的可持续发展提供一定的技术支持,结合克拉玛依市所在区域水资源特点,充分收集相关水文气象资料,并对部分周边河流实地测流勘查的基础上,进行新变化形势下克拉玛依市地表水资源可利用量的估算。结果显示:1白杨河730水文站和克拉苏河径流量呈弱的减小趋势,而白杨河水库入库站断面和达尔布图河径流量呈增加趋势;2上游实施调水后,克拉玛依市可利用的地表水资源量比现状年将减少10.4%,频率为50%、75%、95%下将分别减少11.4%、12.5%和8.8%;3由于上游拦蓄工程修建,特枯年份可供克拉玛依市利用的地表水资源量只能靠调水工程补给,克拉玛依市社会经济的发展将面临严峻的考验,应及早的制定相应的应对措施及应急预案。

In order to cope with the water shortage problem in Karamay under the condition of new changes,and fully consider the local conditions and developing appropriate responses in advance,it will provide some technical support for the sustainable development of industry,agriculture,economy and society.Combination of the characteristics of regional water resources in Karamay,hydrological and meteorological data are fully collected,and based on the site investigation of the part of the surrounding rivers and water flow measurement,the available quantity of surface water resources in Karamay under the New Changes Situation is estimated.It is found that the runoff in 730 Hydrological Station of Baiyang River and Kelasu River showed a weakly decreasing tendency,the runoff in storage station section of Baiyanghe Reservoir and Darbetu River showed an increasing tendency.After the implementation of upstream water diversion,the surface water available in Karamay will be reduced by 10.4% compared with the current frequency of50%,75% and 95% will be reduced by 11.4%,95%,12.5% and 8.8%.Due to upstream impoundment engineering construction,particularly dry year available surface water resources in Karamay can only rely on the use of the diversion project supplies,the socio？economic development of Karamay will face a severe challenge;it should try to early develop appropriate measures and contingency plans.
