中文摘要	黑河为西北地区第二大内陆河,属祁连山-河西走廊水生态二级区。针对其河道基本生态需水不足、河湖面积萎缩、河流地貌及生境形态严重破坏、土地沙漠化加剧等问题,采用Qp法和Tennant法分析了河道最小生态基流和年内不同时期生态流量,确定了全年河道生态环境需水量,研究了黑河张掖市城区段水生态的治理实施方案,提出了适用于内陆河风沙危害严重区段的河(湖)水-生态河岸-滨岸带-防风固沙林带组成横向生态系统结构的治河模式和内陆河筑湖造境的生态治理模式。研究和实施效果表明:生态环境需水量的计算方法能够较好地适应黑河流域水文特征,提出的治河模式和筑湖造境治理方案对内陆河风沙危害区河道的水生态治理工程建设起到了示范效应,具有科学性和实用性,可为同类工程提供借鉴和参考。
英文摘要	Heihe River is the second largest inland river in Northwest China,which is graded as the second class on water ecology in Qilian Mountain-Hexi Corridor area.At present,the unmet basic ecological water demand of the river course,shrinking of the river and lake areas,serious damage to the river landform and habitat form,as well as the aggravating land desertification have caused the degraded ecological function of the river course.In this paper,the Qp method and Tennant method were used to analyze the minimal ecological basic flow and ecological flow in different periods of the year,through which the annual ecological water demand of the river was determined and the implementation scheme of water ecology control in Zhangye urban section,Heihe River was discussed.Based on the study,a new river control pattern suitable for the management of inland lakes suffering from severe threat of wind and sand was put forward.This pattern is composed of the management of river(lake)-ecological river bank-coastal zone-windbreak zone.This approach can not only control the ecological system of the inland river horizontally,but also create new landscapes of manmade lakes.The study and implementation results indicate that the calculation method of ecological water demand can better adapt to the hydrological characteristics of the Heihe River Basin,the implementation effect of the proposed river control pattern can serve as a role model for the water ecological control engineering of the inland rivers suffering from severe threat of wind and sand.This approach is scientifically feasible,it can provide reference for similar engineering projects.
