径流的产生及其动态是水文学的基础，对水资源管理至关重要。基于同位素过程线方法，对天山山区两条典型内陆河（天山北麓、天山北麓、天山北麓）的产流机制进行了探讨和比较，根据一年来频繁监测的天气、流量和同位素数据，结果显示如下：（1）乌鲁木齐河和黄水沟河的降水、河水和地下水稳定δ 18 O和δD组成具有明显的时空变化，融雪期河水δ 18 O有增加的趋势;（2）同位素过程线分离表明，地下水一般是主要补给源（流量的50%以上），其次是这两条河流的冰川融化、融雪和降水，乌鲁木齐河来自冰川融化的贡献大于黄水沟河;（3）除春季外，黄河与黄河的地下水贡献分量基本相同，春季黄河与黄河的地下水贡献分量基本相同（4）乌鲁木齐河对气温变化的敏感性高于黄水沟河，乌鲁木齐河冰川融化可能引发洪水。
Runoff generation and its dynamics are fundamental to hydrology and very crucial to water resource management. Based on isotope hydrograph method, we explored and compared the runoff generation mechanism of two typical inland rivers in the Tianshan Mountains (i.e., Urumqi River on the north slope and Huangshuigou River on the south slope), based on a year-long frequently monitored weather, flow and isotope data. Results show the following: (1) In both rivers, precipitation, river water and groundwater exhibit noticeable spatial and temporal variations in stable δ18O and δD compositions in the Urumqi River and Huangshuigou River, and there is an increasing trend of δ18O in the river water during snowmelt period; (2) isotope hydrograph separation shows that generally groundwater is the major recharging source (over 50 % of streamflow), followed by glacier melt, snowmelt and precipitation in these two rivers, and Urumqi River has a larger contribution from glacier melt than Huangshuigou River; (3) these two rivers have similar contribution components in all seasons except spring in which Huangshuigou River has similar contributions from groundwater (55.6 %) and snowmelt (44.4 %) whereas Urumqi River has a larger contribution from groundwater (72.7 %) than snowmelt (27.3); (4) the Urumqi River is more sensitive to the temperature change than the Huangshuigou River, which might cause flooding that resulted from glacier melt in the Urumqi River.
