Abstract:

In order to study influence of quantitative degree of climate factors and human activities (environmental changes) on the surface runoff, clustering analysis was applied to determine the benchmark period of the Luanhe River Basin runoff variation and influence period of human activities, and HBV model was used to restore the natural runoff, identify the quantitative analysis influence degree of climate change and human activities for the Luanhe River Basin. The results showed the period before 1979 was the benchmark period of the runoff series, HBV model has a good simulation effect on the Luanhe River Basin runoff, human activities have an intensified influence on the runoff. After 1980, natural runoff and measured runoff separated. The change of human activities affected period (1980-2007) was compared with the benchmark period (1960-1979). The influence of climate factors and human activities on runoff amount accounted for 55% and 45% of the total reduced runoff. At different levels, human activities have different effects on runoff, but the analysis found that with the intensification of human activities, the impact of climatic factors in the Luanhe River Basin is gradually weakened, the impact of human activities is increased in the basin.

Key words: climate change, human activities, runoff, cluster analysis technique, HBV model
