摘要：在小集区技术和定位观测综合实验测定的基础上，研究分析了尖峰岭热带山地雨林更新林生态系统３年间的水文学过程、水质的动态变化、营养元素积累。结果表明：水量及营养元素的输入、再分配和输出量主要集中在雨季的５～１０月份，两者月动态变化特征密切相关，年降水输入营养元素的７８％被森林生态系统积累。
Based on the technique of small catchment and the measurement of integratedexperiment,the nutrient tendency with the hydrological processes of rainfall,throughfall,stemflow and total runoff for 3 years were studied and analyzed at the regenerative forest oftropical mountain rain forest in Jianfengling,China. The results showed:(1)85.4 percent of annual precipitation was distributed in rainy reason May to Octo-ber, 15.1 percent of rainfall was intercepted by the forest canopy in rainy reason,19.7 per-cent of rainfall was intercepted by that in dry reason. 50 percent of annual rainfall waswashed away by the total runoff. The system had marked a lag-phase on the runoff with therainfall processes. (2)There was a close relation between tendency changing of the nutrient storage and hy-drological changing,Main storage of hydrochemical matter was at rainy reason. Except Ca,annual nutrients input of the internal rainfall of forest could be increased by 1.5～18.7 timesmore than that of the precipitation,and main input by both distributed in the rainy season. (3)Except Si,annual accumulation of the nutrients in the catchment amounted to about78 percent of the nutrient input amounts by rainfall,particularly Org. C,K,Ca and N. Theaccumulative order of elements in the catchment as follow:Org. C>K>Ca>N>Mg>Mn>P>Al>Si. Analysis results displayed that the system not only had significance hydrologic benefitbut also had store function of hydrochemical matter.
