[目的]研究南京城市森林枯落物及土壤持水能力. [方法]对南京紫金山地区四种典型林分的枯落物储量、土壤容重、土壤孔隙度、枯落物和土壤持水量等因子进行了研究. [结果]马尾松纯林枯落物储量最高,整个枯落物层的蓄水量为马尾松纯林>枫香马尾松混交林>枫香栎树混交林>落叶阔叶杂木林;枫香栎树混交林的总孔隙度、非毛管孔隙度要远大于其他3个林分,并且土壤持水量也最高;不同林分枯落物和土壤的综合蓄水能力的大小顺序为枫香栎树混交林>落叶阔叶杂木林>枫香马尾松混交林>马尾松纯林.[结论]就4种林型的水源涵养能力来说,枫香栎树混交林为最优林型.

[Objective] The urban forest litter in the Nanjing city and its water-holding capacity in soil was studied.[Method] The reservation of forest litter,soil bulk density,soil porosity,kind of litter,water-holding capacity of the litter in soil and other factors of four stand types in Zijingshan region of Nanjing was studied.[Results] The results showed that the reservation of pure masson pine litter was highest and the order of the water-holding capacity of entire layer of litter was as follows:pure masson pine > mixture of masson pine and liquidambar > mixture of liquidambar and oak > broad-leaved forest. The total porosity and non-capillary porosity of mixture forest of liquidambar and oak were much larger than these of other three stand types,and also it was with the highest water-holding capacity in soil.The order of the different forest litter and its water-holding capacity in soil was:mixture forest of liquidambar and oak > broad-leaved forest > mixture forest of masson pine and liquidambar > pure masson pine.[Conclusion] The mixture forest of liquidambar and oak was the best type among four stand types in the capacity for water conservation in soil.
