Abstract

The indicators of water quality of rainfall and stream water from secondary forested watershed in Qianjiangyuan Forest Ecology Station were measured from monthly collected samples, and then analyzed through comparing and contrasting. It was found that the average of concentrations of DO in water from secondary forest watershed was 8.10 mg·L-1, 1.12 times of that in rainfall. The corresponding value for TN was 7.68 mg·L-1 and 4.49 times. The average of concentrations of BOD5 in rainfall water was 2.10 mg·L-1 and 1.31 times of that in secondary forest watershed.The corresponding values for CODMn were 2.05 mg·L-1 and 1.16 times, for NH3-N were 0.97 mg·L-1 and 7.46 times, for TP were 2 times of that in secondary forest watershed. The results showed that most water quality index (DO, COD, BOD, TP and NH3-N) under secondary forest ecosystems were improved significantly. Except TN and pH, other water quality index conformed grade I of "Environmental Quality Standards for Surface Water".
