摘要：3a对海南岛尖峰岭热带山地雨林集水区岩石、土壤及水化学质流含量的检测 ,雨林集水区降雨、总径流水体 COD、NH+4 - N、酚、Zn、Cu、Pb、Cd、Ni的加权浓度含量远低于地面水质 类标准 ;岩石组成属钾长石类 ,其 8项测定的重金属中 Zn、Mn、Pb含量相对较高 ,水质迁移中以溶解、水解及氧化为特征 ;在降雨—径流水循环中 ,山地雨林冠层减少降雨中 COD、NH+4 - N、酚、Zn、Cd、As、Ni、Fe浓度含量范围在 32 %～ 82 % ;土壤层对进入林内的雨水中的 COD、Cu、Zn、Mn、Fe产生吸附效应 ,雨林系统对降雨中 COD、NH+4 - N、酚、Cu、Zn、Cd、Fe贮滤强度分别达 44.4%、2 3.7%、40 .2 %、8.9%、5 7.0 %、2 7.7%、88.3% ,热带山地雨林生态系统具有显著的水化学贮滤净化的生态效应。
Based on measuring of elements contents for rock,soil and hydrochemistry flow since 1995 in Jianfengling tropical mountain rainforest, concentration values of COD,NH + 4 N,phenol,Zn,Cu,Pb,Cd,Ni in precipitation and total runoff for two rainforest watershed were more low than that of the first standard of area water environment. Main consisting of the rock belongs to the potash feldspar in which content of Zn,Mn and Pb is high relatively for measuring of 8 weight metal. Elements migrating of rock in water is main chemistry effloresce with dissolve,hydrolyze and combustion in the system. Concentration content of COD,NH + 4 N,phenol,Zn,As,Cd and Ni in rainfall was decreased range from 32% to 82% by the canopy layer.The soil layer could bring the absorb effect on COD,Cu,Zn,Mn,Fe by net rainfall.The rainforest system could store contents of COD,NH + 4 N,phenol,Cu,Zn,Cd and Fe by rainfall input of 44.4%,23.7%,40.2%,8.9%,57.0%,27.7%,88.3% respectively.The tropical mountain rainforest ecosystem has a marked purify function of water quality.
