中文摘要	哈思山位于我国西北干旱半干旱地区,具有非常重要的区域生态效应。2013年5月到2014年1月,对该地区9个采样点的泉水流量进行了逐月采样,并测定了水体氢氧稳定同位素,研究了泉水流量的变化规律及氢氧稳定同位素的特征。调查结果显示,哈思山泉水为基岩裂隙水,泉水流量无明显的季节性变化,可能受包气带、土壤的持水性及汇水面积和海拔高度等因素的影响。同位素研究结果显示,氢氧稳定同位素值没有明显的季节性变化,且呈现deltaD=5.7439delta~(18)O-10.6535的线性关系,表明泉水的补给来源主要是大气降水,且林区受到强烈蒸发作用的影响;此外,delta~(18)O值与泉所在海拔高度之间存在显著的线性关系,deltaD值也存在一定的海拔效应,但并不显著。最终研究表明,位于半干旱地区的哈思山山区的水文过程十分复杂,泉水流量影响因素较多。
英文摘要	Hasi Mountain is located in the arid and semi-arid areas of the northwestern China. This mountain plays a very important ecological role in the local environment. Based on the spring flow and the stable isotopes of hydrogen and oxygen of the 9 sampling springs in the mountain area, we analyzed the sources and influencing factors of the spring flow as well as the characteristics of hydrogen and oxygen stable isotopes and its implications. The results show that the springs belong to bedrock fissure water. The flows show no obvious seasonal changes,which indicate that the flow may be affected by the aeration zone, water hold capacity of soil, catchment area and altitude.The spring hydrogen and oxygen stable isotopes present a linear relationship (deltaD = 5.7439delta~(18)O -10.6535), without seasonal variations.This suggestes that spring is supplied mainly by the precipitation, and affected by the strong evaporation. There is a significantly linear relationship between the altitude of the spring and delta~(18)O. Similarly,deltaD values show a linear relationship with thealtitude,while the correlation is not statistically significant. The results show that the hydrological processes in the Hasi Mountain eco-hydrology of forest in the semi-arid region is very complicated.
