摘要
径流是降雨及冰雪融水等在重力作用下沿地表或地下流动的水流,对地形地貌的形成、下垫面的发育、流域生态环境的发展、以至于人类生活供水和工农业生产等多个方面都产生了重要的影响。水利工程的建成对于经济发展、社会进步起到巨大作用,但也改变了径流的原始产流汇流模式和河床形态,形成径流变异,甚至对流域的自然地理和生态环境产生重要影响。本文以北江流域的飞来峡水库为研究对象,以对飞来峡水库下游的石角站的流量数据为研究基础和数据依据,确定年平均径流等13个研究指标,通过石角站的数据,利用Mann-Kendall等3种趋势分析方法总结相应指标的变异趋势,利用IHA法对比飞来峡水库建成前后各个指标的变化情况,分析并评价飞来峡水库建成对流域径流的影响。
Runoff is rain and snow melt water flowing under the action of gravity in the surface or underground water, impacting greatly on the formation of topography, the development of underlying surface, the development of River basin ecological environment, the human life water supply, industrial and agricultural production, etc. However, these projects also change the original runoff confluence model and the river bed form, informing the runoff variation, even the basin natural geography and the ecological environment. This paper studies on the Fei Lai Xia Reservoir on Beijiang river basin, based on the runoff data of Shijiao station, located at the downstream of Fei Lai Xia Reservoir. 13 indicators are calculated and 3 trend analysis methods such as Mann-Kendall method will be used to summarize the variation trend of the indicators. It also compares the changes of the construction of the reservoir, and estimate the influences of Fei Lai Xia Reservoir on the Variation of Beijiang River Basin Runoff.
