日前，歷時近五年建設，由(you)中國電(dian)建所屬水電(dian)基礎局(ju)、水電(dian)十(shi)五局(ju)參建的新疆維吾爾自治區重點水利工(gong)程(cheng)吐魯(lu)番大河(he)沿引水工(gong)程(cheng)建成蓄水。
新疆吐(tu)魯(lu)番(fan)是典型的干旱地(di)區，年(nian)降水(shui)量(liang)僅16毫(hao)米，蒸發量(liang)卻高達(da)3000毫(hao)米以(yi)上；同時(shi)由(you)于(yu)盆地(di)地(di)形，四面高山(shan)(shan)環繞，特殊的地(di)形條件使水(shui)資源阻隔在中高山(shan)(shan)區地(di)段，難以(yi)補(bu)給山(shan)(shan)口以(yi)下平原地(di)區地(di)表(biao)水(shui)和地(di)下水(shui)，導(dao)致(zhi)該地(di)區長期面臨缺水(shui)難題。2015年(nian)底(di)，國家開始啟(qi)動實施大河沿引(yin)水(shui)工程，在吐(tu)魯(lu)番(fan)山(shan)(shan)區上游處建造一(yi)座(zuo)以(yi)農業灌溉、防洪和工業供(gong)水(shui)為主的水(shui)利樞紐，將發源于(yu)博格達(da)山(shan)(shan)的大河沿河引(yin)入下游，徹(che)底(di)解決(jue)吐(tu)魯(lu)番(fan)市生(sheng)(sheng)產(chan)生(sheng)(sheng)活用水(shui)問題。
該工(gong)(gong)(gong)程(cheng)是(shi)吐(tu)魯(lu)番市重要水(shui)(shui)源工(gong)(gong)(gong)程(cheng)，位于高昌(chang)區大河沿鎮北部山(shan)區，距吐(tu)魯(lu)番市約(yue)60公里，水(shui)(shui)庫總庫容(rong)3024萬立方米，是(shi)一座以城鎮供(gong)(gong)水(shui)(shui)、農業灌溉和(he)工(gong)(gong)(gong)業供(gong)(gong)水(shui)(shui)為主的綜(zong)合性水(shui)(shui)利樞紐(niu)工(gong)(gong)(gong)程(cheng)。該工(gong)(gong)(gong)程(cheng)每年將向(xiang)高昌(chang)區和(he)221團生活、工(gong)(gong)(gong)業和(he)農業用(yong)水(shui)(shui)供(gong)(gong)水(shui)(shui)達到6900萬立方米，同(tong)時能夠滿足(zu)高昌(chang)區10萬畝的農業用(yong)水(shui)(shui)需求。
完(wan)成蓄水(shui)(shui)后，大河(he)沿(yan)水(shui)(shui)資源(yuan)配(pei)置將得到進一步優化，當地灌區灌溉保證率將提高至(zhi)75%，灌區春(chun)季(ji)灌溉季(ji)節(jie)性缺(que)水(shui)(shui)問題(ti)將得到極大地緩解。
