摘要:对流溪河27个水源林汇水区地下径流、5个河段、3个湖水中12项元素检测,各检测区的水温、pH、DO、TDS、BOD5、Pb、Cd范围分别为19.0~22.5℃,6.36~7.65,82%~94%,7.65~95.6mg·L-1,0.20~3.30mg·L-1,0.04~<0.0001mg·L-1,≤0.0001mg·L-1;其中17个集水区径流的氨氮、硝态氮、Cl-、SO42-均值分别为0.484mg·L-1,0.292mg·L-1,2.792mg·L-1,2.264mg·L-1,总磷在0.0108~0.1143mg·L-1之间.采用水质指标叠加统计及GB3838-88评价,84%的检测区径流为清洁优质水.8.5%的检测区径流为尚清洁水,检测区径流水质聚类结果也相吻合,水源林具有贮滤净化水质效应.
The measured data in 35 forest watersheds with 12 indexes of water quality were analyzed by means of the average index. The results show that there is high quality water in the forest watershed. The water quality index of the 30 investigated watersheds achieved the first standard (water quality index P≤0.2). Contrasting with the rainfall, the forest ecosystem has purifying function on the NH4+-N, Cl- and P in precipitation. At same time, the similar analysis has identical views with the appraising of the average index of water quality. The water quality of Liuxihe forest watershed is good. The research has provided basic reference material for the regional water environment.
