Aimed at spring ditch of no data region in Xinjiang,this paper took runoff investigation computing project of five spring rivers and spring well in Beita mountain of Wulunbulake of Xinjiang as typical example. It used the three methods such as runoff depth regional consolidation method, runoff coefficient method and fold coefficient method to analyze and estimate the average annual runoff of the project area of ditches and springs and compare the calculated results.Finally,the paper recommended fold coefficient method witch provides a feasible way for resolving runoff calculation problem to no data region Spring ditch in Xinjiang.
