针对艾不盖河流域水流复杂、资料短缺及水库下游河道两岸保护对象实际情况，本文将3S技术与水力学耦合对水库下游防洪方案进行研究，建立了以ArcGIS为平台，实时加载遥感影像资料，耦合HEC-RAS的艾不盖河塔令宫水库下游河道以及两岸区域模型。模拟了天然洪水以及塔令宫水库经水库错峰运用后，水库下游河道及两岸区域的洪水演进情况，确定水库下游河道现状防洪能力。在此基础上确定防洪工程总体布置方案，通过不同方案工程总投资对比分析确定塔令宫水库下游防洪方案为：塔令宫水库通过错峰运用，溢洪道及泄洪洞闸门开启自由泄水，水库不增加防洪库容，水库下游单独整修和新建堤防。

Aimed at the characteristics of complex flow , data shortage , and protected object of Aibugai River basin , the paper coupled 3 S technology with hydraulics to research flood control scheme in the downstream of reservoir , and built the regional model in downstream chanel of Talinggong reservoir of Aibugai river and its two sides coupled with HEC-RAS based on ArcGIS platform , real-time loading of re-mote sensing images .It simulated the flood routing in the downstream after the operation of natural floods and.And then,it determined the actual flood protection ability of the channel .Based on the results of simulation , the general layout of flood control project was determined .The flood protection scheme was determined through comparing the total investment of different programs which is that after the operation of peak-alternation of the reservoir ,to open the spillway and spillway gate for free discharge .The reservoir does not increase the flood storage and the downstream of reservoir is separately repaired and the new dike is built .
