Abstract:: Within the dark coniferous with elevation from 2 900~3 100 m in Gongga Mountain, the variation characteristics of pH, ion content, TN, TP in precipitation, through-fall, stem-flow, swamp, soil and runoff are analyzed. The results indicated that: (1) because through-fall and stem-flow absorb amount of acid material, pH value increased; the swamp can absorb and deposit acid material, which makes water quality be better; when the water flow through soil, its pH value increased; surface water can dilute acid material; (2) the ion content of HCO₃^- is the highest in negative ion, Ca²⁺ is the highest in positive ion, the content of total ions in dry and wet season is different. All the ion content is higher when drop through canopy except Na⁺, swamp have stronger absorb ability on K⁺, Ca²⁺, Mg²⁺, while soil can absorb more HCO₃^-, swamp and soil can purify water; (3) the ratio of N/P of swamp, soil and surface runoff in Gongga Mountain is more than 16, which indicated that the limited factor of vegetation is P; the variation curve of N, P in precipitation, through-fall, stem-flow, surface runoff, swamp, soil is similar, swamp have the highest N, P content. So, swamp and soil can leach and absorb lots of ion, N, P, which have the function of purifying water.
