| The paper puts emphasis on the study the problem of the irrigated area reservoir dispatcher in Baojixia , has probed into the method which is solving short of water of regional resource of Guanzhong area. The present situation of water resource shortage in Baojixia irrigation area is very severe, therefore, to use hydraulic engineering is very important to increase the irrigation water supply. This paper according to the characteristic of comprehensive reservoir, based on the theory of "decompose-coordination" for large-scale systems, the optimal model has been built to achieve the minimum surplus water for utilizing water resource. First of all , optimize the progress that the dispatcher studies after reviewing the domestic and international reservoir , has analyzed the subject matter of the existence, direction of development after the discussion . Because the Baojixia irrigation area is very severe, t is the area lacking of water of the resource, alleviate or solve the imbalance between supply and demand of water resource of the irrigated area , besides taking measures of economizing on water, building water storage project and stepping the basin to adjust water project etc, should fully give play to the role of already becoming the water conservancy projects at first , realize the project of many kinds of sources of water is jointly used , allocate in unison, make the water resource get effective , abundant application. The project of source of water is jointly used , allocates in unison, make the water resource get abundant , effective use . However, the project of regional large and medium- sized source of water in area within the Pass has the system of one's own, separate basically for a long time, measure it is which form organic for dispatcher, can't surplus and deficiency not complementary, make water resource that develop not own unable to last use not abundant, have caused certain resources to waste. Allocate the problem from main key element – quantity, time , space , comprehensive analysis and research Baojixia irrigation area optimization , irrigated area of water yield , user of nature , water of resource distribution, it is analyses that the project of source of water optimizes the necessity and feasibility allocated , more rational than to elect project of source of water optimizes the scheme of allocating. This have certain reference function to many resource of water,many goal development and utilization of water resources planning in the future too.This text proceeds from thought , theory of the system engineering, regard abundant , rational utilization of the water resource as the goal, gorge equilibrium of supply and demand , irrigated area of water yield is it for main content , analyzed Baojixia to be current situation annual mainly to analyses with Baojixia irrigation area, Linjiacuen canal add floodgate and Xiaoshuihe reservoir is it support influence of water requirement to whole irrigated area to build up 2010 for the first time and Taohe river supply Weihe river in2020,2030. Adopt and optimize technology and carry on overall, deep studying to the irrigation works in the irrigated area most, put forward the feasible suggestion and feasible measure and scheme of optimizing the dispatcher. Through introduction of project of regional source of water in area within the Pass, is it step basin transfer feasibility and his main project measure of water to prove emphatically finally.Show through analyzing and researching: Linjiacuen irrigated area irrigate guaranteeing rate to be very much difficult to satisfied with under the terms in existing project, only through Weihe river tributary Xiaoshuihe reservoir benefit water , Xiaoshuihe reservoir make present lack of water state alleviate in Linjiacuen.To fort irrigated area of the Weijiabu, because riverhead of system have water , irrigated area lack water and abandon water synchronous very strong, in time have surplus and deficiency complementary terms basically at the course, can only meet the water yield demand of the irrig...
