摘要
为了分析上下游区域水量分布特征,以临沂流域为研究区,结合流域水量平衡分析理论,构建了临沂流域分布式水文模型SWAT,进行了临沂流域产水模拟。在此基础上,给出临沂流域上下游区域水量时空分布图,并结合临沂上下游流域经济发展及用水情况,分析了临沂流域上下游区域的水资源分布及供需状况。研究结果表明:对于半干旱区中尺度流域采用多站点多时段多要素的率定方法,能够提高SWAT模型的模拟效率;临沂流域上下游水资源均较丰富,能够满足工农业生产和人们生活需要;临沂流域水量在时空分布上极不均匀,容易发生旱涝灾害,应加强水利设施建设。
To study the water balance between upstream and downstream, the SWAT model in Linyi basin is built coupling water balance theory, and the runoff generation in Linyi basin is simulated. The temporal and spatial distribution of runoff map in Linyi basin is built. With the analysis of economic status and water-use upstream and downstream in Linyi basin, the demand and supply of water is researched. The results show that multi-site and multi-variable method can greatly improve the efficiency of SWAT model in middle basin on semi-arid area;the abundant water re- sources in Linyi basin can meet the needs of local production and living, but the water in the basin was heterogeneous in time and space, which make drought and waterlog occur easily, thus irrigation works should be reinforced.
