Based on the data from 2001–2016, we investigated the variation trends in surface water and groundwater reserves of the Narenguole River, their response relationship and influencing factors. The trend distribution of groundwater reserves is uneven and the seasonal variation is obvious. The co-varying change of surface water and groundwater reserves presents a “stable-decrease” trend in the northern part of the basin. In the part of the Tulagt Ar Gol River, the surface water decreases but the groundwater increases, while the “stableincrease” and the “decrease-decrease” co-varying trends are observed respectively in the West and East Taijinar Lakes of the rump area. The main factors influencing the change of water reserve include temperature, soil section thickness, irrigation factors and population factors. Based on the response characteristics of surface water and groundwater changes in different areas of the basin, we get insights into the typical non-consistent response relationship between them, which is very helpful to realize the integrated management of surface water and groundwater and the protection of ecological environment in the basin.

基于2001—2016年的地表水和地下水储量数据, 分别从年尺度和季节尺度研究那仁郭勒河流域地表水与地下水资源变化趋势, 分析地表水与地下水的响应关系及其影响因素。结果表明, 那仁郭勒河流域地表水储量和地下水储量变化趋势分布不均匀, 季节差异明显。地表水–地下水储量变化响应在流域北部集中呈现“地表水稳定–地下水减少”的趋势, 在库拉克阿拉干河段呈现“地表水减少–地下水增加”的趋势, 在尾闾地区东西台吉乃尔湖分别呈现“地表水稳定–地下水增加”和“地表水减少–地下水减少”的趋势。水储量变化的主要影响因素包括温度、土壤断面厚度、灌溉面积及人口密度。流域内不同区域的地表水与地下水储量变化响应特征具有很大的差异, 对二者之间的典型非一致性响应关系的深入认识有助于实现流域地表水与地下水联合管理及生态环境保护。
