Through analyzing the natural geographical background economic development situation of Hutuo River, this paper divided it into three water resource areas: the region above Jiehepu (Ⅰ zone was forming and watering environment), the region between Jiehepu and Jisheng bridge (Ⅱ zone was watering environment), the region from Jisheng bridge to Nanzhuang (Ⅲ zone was watering environment). The paper probed the water resources evolution law of Hutuo River in mountainous area in recent 55 years by using the hydrological and meteorological data since 1950s. The result showed that the surface water resources reduced year by year in Hutuo River in mountainous area, and the turning period of the positive and negative anomaly was in the 1970s. The groundwater mainly reflected in the level declining year by year in Xinding basin. It dropped 1.04 m per year on average. And the exploitation district area increased. The decrease of water resources was affected jointly by climate change and human activities in Hutuo River in mountainous area. The influence of climate change, water conservation and water conservancy accounted for 38.6%,26.4%,35.0% of he declined total runoff, respectively. And human activities accounted for about 61.4%. Due to climate change, the water resources in Ⅰ zone, Ⅱ zone, Ⅲ zone reduced by the rates of 0.88%, 0.61%, 0.41%, respectively, per year on average. Human activities made the water resources respectively reduce by the rates of 1.31%,1.14% and 0.71% per year on average. Climate change and human activities on water resources changes had the same degree of obvious regularity: The impact degree decreased from the source to the downstream. Two ways of human activity had obvious regional differences. The influence size order of soil and water conservation activities was Ⅲ zone, Ⅰ zone, Ⅱ zone. And the influence size order of water conservancy project activities was Ⅱ zone, Ⅰ zone, Ⅲ zone.
