2000-2004年黑河流域生态调水

黑河流域是河西走廊和内蒙古高原西部著名的粮仓和绿洲。随着气候和人类活动等各种因素的影响,特别是中下游地区水资源配置严重失衡,导致下游荒漠化和沙漠化日趋严重,生态环境急剧恶化,下游额济纳地区已成为我国北方地区沙尘暴的沙源地之一,危害之广,波及西北、华北,乃至更广大地区。对此,党中央、国务院十分重视,多次指示加强管理,治理黑河。从2000年开始一场以水资源合理配置为核心的黑河干流水量统一调度以及流域综合治理全面启动,本文主要阐述2000-2004年水量调度情况,对中下游地区调度前后水文、气象资料作对比分析,以期引起社会各界了解、重视,进一步做好黑河水量统一调度工作和水文监督、监测工作。

The Ecological Water Dispatching in the Heihe River from 2000 to 2004

The Heihe River is the famous grain-productive place and oasis in the Hexi corridor and the west of Mongolia altiplano.With the influence of the climate and mankind activities,especially the allocation of water resource is badly overbalance in the middle and downstream of the Heihe River,which lead the downstream to desertification more and more seriously,and the ecological environment is deterioration rapidly,Ejina county,which locates in the downstream of the river,now has been one of the source area of dust storm in North China,which endanger the North-West,the North China and more areas.Now the Party central committee and the State Department of China attach much importance to it,command involved department to strength management and father Heihe.From 2000,enclosed the rational allocation of water resource,the united water dispatching in the trunk of the Heihe River and the comprehensive treatment is all-sided startup.The article expatiates the water dispatching from 2000 to 2004.by contrastive analysis the hydrology and the climate data before and after the water dispatching in the middle and downstream of the river,which expect the society to understand and put a high value of the water dispatching,so as to promote the water dispatching and the supervision and monitoring of hydrology project.
