摘要:
以广西龙胜县龙脊梯田水源区5种天然次生林(Ⅰ)毛竹冬青林、(Ⅱ)杉木毛竹林、(Ⅲ)杉木石栗林、(Ⅳ)密花马尾松林、(Ⅴ)杉木马尾松林为研究对象，采用野外调查与室内浸泡的方法，探究5种林分枯落物的水文作用。结果表明：各林分枯落物厚度在3.4～5.8 cm之间，储量范围为13.43～29.60 t/hm2。5种林分枯落物最大持水率范围在580.46%～725.90%之间，可有效拦截降雨为0.89~2.23 mm。各林分枯落物水文功能杉木马尾松林>杉木石栗林>密花马尾松林>毛竹冬青林>杉木毛竹林。研究表明龙脊梯田水源区杉木马尾松林水文作用最强。
Abstract:
Based on the combination of field observation and analysis on experimental data, a study on hydrological effects of litter layer was conducted in five kinds of forest stands:(Ⅰ) Phyllosta-Stachysedulis+Ilex chinesis,(Ⅱ)Cunninghamia Lanceolata+Phyllostachys edulis,(Ⅲ)Cunningham Lancelot+Alacrities moluccana,(Ⅳ)Rapanea neriifolia+Pinus massoniana,(Ⅴ)Cunninghamia Lanceolata+Pinus massoniana in Longji Terrace. The result shows: the thickness in different forest stands litter layer ranges from 3.4 to 5.8 cm, the storage of litter in different forests ranges from 13.43 to 29.6 t/hm2, the maximam water hoding capacity varies from 580.46% to 725.90%, equivalent to 0.89 to 2.23 mm of rainfall. The hydrological effects are Ⅴ>Ⅲ>Ⅳ>Ⅰ>Ⅱ. The Cunninghamia Lanceolata+Pinus massoniana has the most significant hydrological effect in Longji terrace.
