摘　　要：为研究人为活动与全球气候变化对安阳河流域水资源的影响,采用了流域水文模型模拟的方法,计算了人为活动和气候变化对流域水资源量的影响及其贡献率,利用聚类分析方法计算了两者的权重,判定了影响安阳河流域年径流量的主要因素。分析结果表明,人为活动是安阳河流域年径流量变化的主要影响因素,气候变化对流域年径流量的影响在流域内存在空间差异。Hydrological simulation model has been applied to examine the impact of human activities and climate change on annual runoff of Anyang River Basin. Calculation is made to the influence of human activities and climate change on water availability of the basin as well as the rate of contribution. The weight functions of the two are calcu- lated by means of clustering analysis and the key factors that have influences on annual runoff of the basin are decided. The result shows that human disturbance is the main contributor, and spatial difference is existed in the influence of climatic change to annual runoff.
