| 摘 要： | 对中亚热带木荷和杉木人工林(monocu1ture plantations of Schima superba and Cunninghamia lanceolata,15年生)枯枝落叶层(包括Oi、Oe和Oa层)DOC浓度及季节动态的研究表明:木荷人工林枯枝落叶层DOC浓度高于杉木人工林;两种群落枯枝落叶层中,Oi层的DOC浓度均高于Oe和Oa层;木荷和杉木人工林枯枝落叶层不同分解层次DOC浓度的季节变化模式相似,均在秋季出现最大值;枯枝落叶层DOC浓度及季节变化与温度、湿度、生物活性及枯枝落叶层中有机质数量等有关.

| Abstract: | The concentrations and seasonal dynamics of DOC in forest floors of two plantations of Schima superba(SS) and Chinese fir(Cunninghamia lanceolata,CF) in jianou,Fujian were studied.The results showed that the SS had higher DOC concentration in the forests floor than the CF.DOC concentration in the Oi horizon was higher than those in the Oe and Oa horizons for both forests.Concentrations of DOC in different horizons of forest floors in both forests showed similar seasonal trends with the maximal value in autumn.The concentration and temporal change of DOC in study forests were probably related to the variation in moisture,temperature,biological activity and quantity of organic matter in the forest floor. |
