摘要：

【背景】气候变化和人类活动可能导致流域水文环境变化，进而影响整个水文系统的稳定性。河道演化是流域水文过程变化的直接体现，分析河道演化规律及驱动因素是评价流域水文情势和预测河道形态未来变化趋势的前提。【方法】本文选取渭河流域甘肃段2008-2015年河道变化为研究对象，以流域地形因子、气象数据、土地利用类型和水文水利工程分布数据驱动地理探测器方法，分析了气候变化和人类活动作用下渭河流域（甘肃段）河道的变化特征及其对各类影响因子的响应程度。【结论】研究表明：1）天水市是渭河流域甘肃段河道变化最多的区域；2）与流域水沙过程相关自然条件的综合作用是河道变化的主要原因；3）人类活动对河道演变的贡献程度正随着社会经济的发展逐渐增加。

Abstract:

[Objective] Climate change and anthropogenic activities may lead to changes in the hydrological environment of the basin, which in turn affects the stability of the basin’s hydrological system. As a direct reflection of the changes in hydrological processes in the basin, analyzing the river channel evolution patterns and driving factors is a prerequisite for evaluating the hydrological situation in the basin and predicting the future trends of the river channel morphology. [Methods] In order to study the evolution of the river channel under the effect of climate change and human activities, this paper selects the river channel change of the Gansu section of the Weihe River Basin from 2008 to 2015 as the research object and analyzes the change characteristics of the river channel in the Weihe River Basin using the GeoDetector method. The method is driven by spatial data including basin topographic factors, meteorological data, land use types and hydrological and hydraulic engineering distribution data. The degree of the response of the river channel morphology to various influencing factors is calculated. [Conclusion] The study shows that: 1) Tianshui City is the region with the most channel changes in the Gansu section of the Weihe River Basin. 2) The combination of natural conditions related to the water-sand process is the main cause of river channel changes. 3) The degree of contribution of human activities to channel evolution is increasing with the socio-economic development.
