摘 要：
1.自然条件克里雅河源出昆仑山北麓,是塔里木盆地南缘较大的河流之一。流域面积7358平方公里,河流全长740公里,出山后中下游平原地段438公里。多年平均径流量6.99亿立米,最大径流量10.76亿立米(1966年),最小径流量5.25亿立米(1979年),径流模数3.01立米/秒平方公里;径流深95毫米;侵蚀模数406.78吨/平方公里;多年平均含沙量4.68公斤/立米,输沙率111公斤/秒。河水pH为8.2,矿化度山口水文站0.51克/升,英巴克0.76克/升,米萨来1.38克/升。克里雅河属冰雪融水与降水混合补给类型,径流年际变化较小,Cv=0.17,水量较稳定,对农业利用有利。但年内季节分配极不均匀。春季占11.7%,夏季66.4%,秋季14.7%,冬季7.2%;洪水期7-8月,枯水期9-5月;1月份流量最小6.31立米/秒,

摘 要：
The Keliya river is one of the larggest riversthat locate in the southfringe of the Tarim Basin.In ancient time, this regions belonged to Yeimecountry. In the historical periods of mankind, with the enlarge of oasesin the upper reaches, the amount of water flowing to lower reaches wasdecreased constantly, the river course became shorter and shorter,the plant cover withered gradually. Meanwhile, the oases that locate inthe lower reaches moved back from north to south and the area ofdesert was enlarged.In order to protect the green corridor moved back the inner of theydesert in the Keliya river, we must controle the irrigating water supplin the upper reaches, increase the amount of water for lower reachesand stop destoring the plant cover on the banks of the river.
