摘要：对浙江钱江源生态站大气降水和天然次生林生态系统的径流水质指标进行逐月取样测试和对比分析。结果表明:天然次生林集水区水体中溶解氧含量年平均值达到8.10 mg·L-1,是大气降水的1.12倍;总氮含量年平均值达7.68 mg·L-1,是大气降水的4.49倍。大气降水的生化需氧量年平均值达2.10 mg·L-1,是天然次生林集水区的1.31倍;化学需氧量年平均值达2.05 mg·L-1,是天然次生林集水区的1.16倍;氨氮含量年平均值达0.97 mg·L-1,是天然次生林集水区的7.46倍;总磷含量年平均值是天然次生林集水区的2倍。研究区大气降水经过天然次生林生态系统后,溶解氧、生化需氧量、化学需氧量、总磷和氨氮等水质指标有明显改善,除总氮和pH值外,其它指标均达到地表水Ⅰ类水质标准。
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＂.
