摘要:
 探讨有利于人工水源涵养林碳汇功能与水源涵养功能协同发挥的最佳间伐强度，为黄浦江水源涵养林经营管理提供科学依据，选择上海市奉贤区杜英林和香樟×重阳木混交林2种人工水源涵养林进行不同强度间伐处理，对其恢复4 a后的碳储量及其垂直分布进行了研究。结果表明：1）间伐4 a后，各间伐强度样地的乔木层地上部分及其根系碳储量均未超过对照样地；2）对于林下层碳储量而言，无论地上部分还是根系，杜英林和香樟×重阳木混交林均在中等强度间伐样地中最大，且大于对照样地；3）各间伐处理均显著地增加了杜英林和香樟×重阳木混交林的凋落物碳储量及其在植物碳储量中所占的比例；4）间伐处理显著地改变了2种林分的土壤碳储量的垂直分布，相较于对照样地中土壤碳储量随深度分布较为均匀，间伐样地中土壤碳储量更为集中于土壤表层，且随深度增加逐渐减少。经过4 a的短期恢复，47%和24%的间伐强度可能分别最有利于杜英林和香樟×重阳木混交林的碳汇功能和水源涵养功能的协同发挥。
Abstract:
Elaeocarpus decipiens plantations and Cinnamomum camphora×Bischofia polycarpa mixed plantations,two common water conservation forests for Huangpu River in Shanghai,were thinned with three thinning intensities.The effects of thinning on carbon storage and the distribution among vertical layers were compared after 4-year recovery.The results showed that:1) After 4-year recovery,carbon storage of tree layers of all thinned stands were lower than that of control stands for both aboveground parts and roots in each plantation type.2) The carbon storage of understory layer was the highest in stands with moderate thinning intensity and even greater than the control stand,for both aboveground parts and roots in each plantation type.3) Comparing to the control stand,thinning management increased the carbon storage of litter layer for each plantation type,as well as its percentage of the whole plant carbon storage.4) Comparing to the control stand,thinning management also altered the vertical distribution of soil carbon storage in depth,from a relatively uniform distribution pattern to a decreasing tendency pattern with more aggregation in topsoil.In conclusion,47% and 24% of thinning intensity were suggested to be the most suitable for Elaeocarpus decipiens plantations and Cinnamomum camphora×Bischofia polycarpa mixed plantations,respectively,which could have the biggest potential to maximize their eco-services of carbon sink and water conservation synchronously.
