摘　　要：本文以奎屯河流域平原区为研究对象,梳理了奎屯河流域降水量、河道径流量和渠道引水量等资料,采用极值比K、Mann-Kendal显著性Z和基于R/S方法计算的Hurst指数H,分析了地下水资源量各组成项演变趋势及持续性,判断地下水资源量演变情势,并分析其原因。结果表明:①地下水天然补给量呈略微增加趋势,转化补给量中河道渗漏补给量总体上呈上升趋势,田间入渗补给量与渠系渗漏补给量先增加后减小,库塘渗漏补给量保持稳定;②奎屯河流域平原区地下水资源量在2008年以前增速缓慢,2008年后增速加快,显著性检验值Z和Hurst指数H说明地下水资源量呈显著增加趋势,且短期内有较强的持续性;③河道渗漏补给量的增加是地下水资源量增加的主要原因。This article focuses on the plains of the Kuytun River Basin.First,we classified rainfall data,river runoff data,water drained from canal data,and other data in the Kuytun River Basin.Second,the authors focused on the evolutionary trends and sustainability of several variables,using extreme value ratio K,Z-test,and Hurst exponent H based on the R/S(Rescaled Range Analysis)method to analyze several variables that contribute to groundwater resources.Finally,the above analysis determines the evolution of groundwater resources and explains the reasons for the related changes.The results showed that(1)the natural recharge amount consisting of precipitation recharge and lateral groundwater recharge showed a slightly increasing trend.Among the transformation recharges composed of other recharges,the leakage recharges of the river channel showed an upward trend.The infiltration recharges in the field,and the canal leakage replenishment increased first and then decreased.Then,the reservoir recharges remained stable,(2)prior to 2008,groundwater resources in the plains of the Kuytun River basin increased slowly,but since 2008 groundwater resources have increased faster.Both the calculated Z-test and the Hurst exponent H proved that the volume of groundwater resources increased significantly.This increasing trend persists strongly in the short term,and(3)the article concludes that the increase in recharge due to river leakage is the main reason for increasing groundwater resources.
