中文摘要	在干旱区研究分析流域径流量的变化特征,是流域管理的重要科学问题。利用19642012年艾比湖流域博尔塔拉河径流、降水数据,采用变异系数、集中度和集中期等指标,对艾比湖流域博尔塔拉河的径流量、降水量在多时间尺度上进行分析,并用集中期来反映径流对降水变化的响应。结果显示,博尔塔拉河径流年际变化较平稳,增长趋势不明显;流域径流主要集中在68月,季节上主要集中在夏季。径流集中期主要集中在6月下旬至7月中旬之间。降水集中期主要集中在57月;年降雨和年径流间存在较高的相关关系,(r=0. 2372>0. 23292 = R0.1,49,回归显著水平超过0.1),径流对降水具有滞后效应,多年平均滞后时间为21 d左右,且滞后天数随着时间推移呈缩小趋势。
英文摘要	To reveal the change characteristics of runoff and their influencing factors has been an important scientific topic for drainage basin management in the arid regions. Taking the Boertala river of Ebinur lake basin as study area,this study analyzed the change trends of the runoff and precipitation in multi-time scales and runoff response to precipitation change according to the precipitation and runoff data in 19642012 based on assessment indices of coefficient of variation, concentration degree, concentration period. Resulting indicated that runoff interannual changes were relatively stable and increased insignificantly in Bortala River; the runoff of Boertala River was mainly concentrated from June to August, concentrated in the summer season. Runoff concentration period mainly concentrated in late June to middle of July and rainfall concentration period mainly concentrated from May to July. Correlation between annual runoff and annual precipitation has high relevance (the significant level is more than 0. 1,r=0. 2372, R0.1 =0. 2329). There is a hysteresis of runoff to precipitation and hypsteresis period is about 21 days, and the hysteresis period becomes short over time.
