摘要: 气候与土地利用变化的水文响应研究是水文水资源领域的一个重要研究课题。本文利用旬河流域1980~1990年的降雨、土地利用等数据资料,采用基于DEM的分布式流域水文模型来模拟该时段的径流过程,并计算气候变化和土地利用变化对径流量变化的贡献率。结果表明:1980~1990年间旬河流域土地利用变化很小,导致径流量减少的主要因素是气候变化。
Abstract: The research on hydrological responses to land use change and climate variability is a significant topic in hydrology and water resource researches. With the precipitation data, land-use data etc. of the Xunhe catchment in the year 1980-1990, a DEM-based distributed hydrological model was applied to simulate the rainfall-runoff processes in the study period and to calculate the contribution of land use change and climate variability to the change of streamflow. The conclusion can be drawn that the land use change of the Xunhe catchment as well as its impact is small during the period of 1980-1990, and the climate variability is the main cause of the decrease of the streamflow.
