摘要：根据尖峰岭热带山地雨林 3个对比集水区的研究 ,天然更新 4 0 a山地雨林生态系统在 5～ 9月份 ,蓄养降水资源的51 .8% ;1 0～翌年 2月份 ,补枯径流水量 1 4 3 .5mm;特大暴雨的径流响应从 3 2 .7%～ 62 .5%、随系统蓄满程度变化。集水区降雨、径流水体 COD、氨氮、酚、Zn、Cu、Pb、Cd、Ni的浓度含量远低于地面水环境质量 类标准 ;山地雨林系统对降雨中氨氮、酚、Pb、Cd、Zn浓度贮滤强度分别达 2 3 .7%、1 4 .1 %、1 6.3 %、2 5.5%、3 2 .3 %、年贮滤流失强度分别为 4 7.2 %、4 0 .6%、4 2 .1 %、4 8.2 %、91 .8% ;特大暴雨洪峰消减时段变化中 ,Cu、Pb流量贮滤达 66.4 %、50 .3 %、Zn浓度含量贮滤强度在 4 9%～ 77.8%、Cd浓度含量贮滤达 92 .9%。天然恢复 4 0 a山地雨林较人工恢复杉木幼林系统 ,台风特大暴雨年的水分循环中 ,山地雨林系统年减少泥沙流失量 6.0 1 t/hm2 ,保存养分 2 4 1 .5kg/hm2 ,无台风特大暴雨年 ,其减少泥沙流失0 .4 3 t/hm2 ,保存养分 1 7.3 kg/hm2。显示出热带林极其显著的水文生态功能。
According to the comparison research of 3 watershed of tropical mountain rain forest in Jianfenling,nature recovery raniforest ecosystem with 40 years could store 51.8% of rainfall from May to September, and could recruit runoff of 143.5 mm from October to February. At the same time,the response of runoff ranged from 32.7% to 62.5% on heavy rainstorm.Concentration of COD,NH + 4 N,phenol,Zn,Cu,Pb,Cd,Ni in precipitation and runoff were lower than the first standard of area water environment in virgin and nature recovering rain forest watershed.And by water cycling,the concentration of NH + 4 N,phenol,Pb,Cd,Zn by rainfall input could be cut down by 23.7%,14.1%,16.3%,25.5%,32.3%,respectively;and 47 2%,40 6%,42 1%,48.2%,and 91.8% of that by rainfall input was effectively stored in the mountain rainforest meanwhile.In the heavy storm process,input output of microelement has marked changes including that the input of Cu,Pb was stored by 66.4%,50.3% respectively,and concentration of Cd was decreased by 92.9% after the peak flood;concentration of Zn was decrease range from 49% to 77.8% with all process.comparing the measurement between the nature recovering and Fir young forest system from 1996 to 1997,It has been found that the former could decrease loss of sand and nutrients with 6.01 t/hm 2 and 245.1 kg/hm 2 than that of the latter per year as influence of typhoon and super storm.Otherwise the former only decreased loss of sand and nutrients by 0.43 t/hm 2 and 17.1 kg/hm 2 respectively than that of the latter per year.
