采用定位观测和多流域检测的方法，研究分析了尖峰岭热带林集水区水质及水质生态效应，４１个检测集水区径流７．０１≤ｐＨ＜８．０４的区域占８１％，ｐＨ值随海拔高度增加而减小；ＤＯ≥６．０ｍｇ／Ｌ的占９０％，随海拔高度增加而增加；ＢＯＤ５≤３．０ｃｍ／Ｌ占９０％，ＴＤＳ≥１１．１ｍｇ／Ｌ占９８％，随海拔高度增加而减小，４项检测值为Ｉ类水质标准；热带山地雨林系统对雨水中水质项的有效功能为：径流中ＤＯ、ｐＨ、ＴＤＳ、Ｍｎ浓度增加，ＢＯＤ５、总Ｎ、总Ｐ浓度降低，热带原始山地雨林系统具有良好的水质净化效益。故实施原始林保护及扩大，对源头水保护、净化、林区居民身心健康是非常有益的。
Positioning and multi-watershed detection methods were used to study the water quality and water quality ecological effects in the watersheds of Jifengling tropical forest. The areas of 41 catchment runoff 7.01≤pH <8.04 accounted for 81%, the pH value With the altitude increased and decreased; DO≥6.0mg / L accounted for 90%, with increasing altitude increased; BOD5≤3.0cm / L accounted for 90%, TDS≥11.1mg / L accounted for 98%, with The results of tropical rainforest system on water quality in rainwater were as follows: the concentrations of DO, pH, TDS and Mn in runoff increased, BOD5, total N, total P Lower concentration, the tropical primary mountain rain forest system has a good water purification benefits. Therefore, the implementation of the original forest protection and expansion of the source of water protection, purification, physical and mental health of residents is very useful.
