| 摘 要： | 采用径流小区法,对中亚热带地区的杉木人工林和米槠次生林在不同雨强下径流量和可溶性有机碳（DOC）流失浓度进行比较研究。结果表明：在小雨、中雨、大雨和暴雨4场降雨过程中,米槠次生林和杉木人工林的地表径流量和DOC流失浓度变化趋势一致,即降雨强度增加,地表径流量也随之增加。DOC浓度均呈现了随着雨强的增加而逐渐降低的趋势。说明降雨强度对径流量和DOC浓度均产生了较为明显的影响;米槠次生林和杉木人工林的地表径流量之间差异不显著,米槠次生林和杉木人工林的DOC流失浓度除大雨外均达到显著性水平差异（P〈0.05）,说明植被类型对地表径流量影响较小,对DOC浓度具有较明显的影响。

| Abstract: | Taking the method of runoff plots,this study compared runoff and the amount of DOC loss from different rainfall intensities in Chinquapin secondary forest and Chinese fir plantations. The result showed that runoff and concentrations of DOC of the plantations were the same regarding the changes.With the increase of rainfall intensity,the runoff increased. However,the concentrations of DOC were going down with the increase of rainfall. This showed that rainfall intensity has a significant impact on runoff and concentrations of DOC. The difference of runoff was not significant,and the DOC was significant except heavy rain between the two types. It showed that vegetations affected less on runoff,and affected more on the concentrations of DOC. |
