摘　　要：为了明晰不同人类活动对流域水文情势的影响效果,基于窟野河径流控制站温家川水文站1954—2016年的日径流数据,采用动态时间弯曲(Dynamic Time Warping,DTW)算法分析了不同人类活动影响期的水文情势相似度。结果表明:①水土保持措施和煤矿开采均大幅减小了窟野河的径流量,其中煤矿开采的采空区储存水量减水效应大于水土保持措施涵养水源的作用;②人类活动弱干扰时期(第一时期)、水土保持时期(第二时期)和煤矿开采时期(第三时期)两两之间的DTW距离分别为0.13(第一、二时期)、0.19(第一、三时期)和0.17(第二、三时期),说明水土保持措施和煤矿开采对流域水文情势的影响效果较为相似;③煤矿开采对非汛期流量、基流的影响历时、最大流量出现时间、大/小流量出现次数的影响均比水土保持措施明显。In order to clarify the effects of different human activities on hydrological regime,this paper analyzed the hydrological regime similarity in different anthropogenic influence phases by using Dynamic Time Warping(DTW),based on the daily runoff from 1954 to 2016 in Wenjiachuan Hydrologic Station.The results show that:a)both soil and water conservation and coal mining have made a considerable reduction of the river runoff.The effect of water stored by coal mining goaf is larger than that by soil and water conservation;b)the DTW distance during weak anthropogenic influence(stageⅠ),soil and water conservation(stageⅡ)and coal mining(stageⅢ)is 0.13 between the stageⅠandⅡ,0.19 between the stageⅠandⅢ,and 0.17 between the stageⅡandⅢrespectively;c)and the effect of coal mining is more obvious than that of soil and water conservation in the runoff of nonflood season,effective duration of base flow,the occurrence time of maximum runoff and high or low flow pulse time.
