【摘要】：收集研究区域内雨量站历年降水量资料,水文站历年径流系列资料以及历年最大洪峰流量、洪水总量成果资料及西土沟敦煌沙漠水文实验研究站实测水文资料,调查该区域内洪水沟道的历史最大洪水。用水文学原理和方法对洪峰流量和洪水总量变化规律进行统计分析,结合敦煌西土沟流域灾害综合治理工程实施情况估算区域水资源可利用量,提出沙漠洪水资源开发利用新模式。结果表明:西土沟流域洪水灾害综合治理工程的实施探索出导流+分洪+工程防护的洪水资源开发利用模式、拦蓄洪水产生地下径流利用模式和沙漠冷水虹鳟鱼养殖到葡萄种植的区域水资源重复利用模式;有效遏制了研究区内沙漠的进一步推进并可显著增加流域内可利用水资源量,实现了区域生态治理与经济发展的良性循环。
[Abstract]:Collecting precipitation data of past years at rainfall stations in the study area, runoff series data of hydrologic stations over the years, maximum Hong Feng discharge over the years, total flood data and hydrological data measured at Xitugou Dunhuang Desert Hydrological Experimental Research Station, This paper investigates the history of the largest flood in the flood channel in this area. The principle and method of water literature are used to analyze the variation law of Hong Feng's discharge and total flood quantity. Combined with the implementation of the comprehensive disaster management project in the Xitugou watershed of Dunhuang, the available amount of regional water resources is estimated. A new model for the exploitation and utilization of desert flood resources is put forward. The results show that the flood resources exploitation and utilization mode of flood diversion and flood diversion engineering protection is explored by the implementation of comprehensive flood disaster control project in Xitugou watershed. The groundwater runoff utilization model and the regional water resources reuse model of cold water rainbow trout cultivation to grape cultivation in desert can effectively restrain the further development of desert in the study area and can significantly increase the amount of available water resources in the basin. The benign circle of regional ecological governance and economic development has been realized.
