Abstract
This paper analysed the changing feature of rainfalL-runoff relationships in the north mountainous area of Daqing river basin before 1980 and after 1980. The result showed that the rainfall-runoff relationship of the river basin was not linear and had been partly altered after 1980 due to the increasing influence of human activities. Through analyzing the rainfall-runoff relationship under the natural and human-impacted conditions, the rainfall-runoff correlations before 1980 and after 1980 are very significant,but the runoff changing rate with annual precipitation was reducing after 1980. This change of rainfall-runoff relationship was related to the level of water resources development and utilization except for the influence of underlying surface factors in the river basin. The study of the rainfall-runoff relationship is important for the exploitation and assessment of water resources.关键词
