摘要:
为了研究江西信丰森林健康示范区林下土壤的水源涵养功能，本文主要采用环刀法，比较分析了6种主要林分土壤孔隙度、持水量、渗透性等水文指标。结果表明：6种林分土壤最大持水量为880.88～1007.36 t/hm2，其大小顺序为：毛竹林>杉木林>常绿阔叶林>火炬松林>湿地松林>马尾松林；各林分土壤的入渗过程均可用Horton入渗模型进行较好拟合，各层土壤初渗和稳渗速率分别变动于0.163～4.433 mm/min和0.112～1.788 mm/min，毛竹林土壤渗透性较好，火炬松较差。6种主要林分土壤水源功能的大小顺序为：毛竹林>杉木林>湿地松林>常绿阔叶林>马尾松林>火炬松林。
Abstract:
Based on core cutter method, an investigation on the porosity, water-holding capacity, infiltration rate of soils (0-60 cm) in 6 forest types was conducted at the Demonstration Area of Forest Health Management Project in Xinfeng County of Jiangxi Province in order to analyze their soils water conservation function and to evaluate forest health. The results indicated that the maximum of soils in 6 forest types ranged from 880.88 t/hm2 to 1 007.36 t/hm2, sequence of water-holding capacity was Phyllostachys pubescens forest>Cunninghamia lanceolata plantation>evergreen broad-leaved forest>Pinus taeda plantation>Pinus elliotⅡ plantation>Pinus. massoniana plantation; The infiltration processes of all soils could be fitted properly by using Horton model, the primary permeability rate and stable permeability rate of all soils varied from 0.163 mm/min to 4.433 mm/min and from 0.112 mm/min to 1.788 mm/min, respectively. The soil permeability of Ph. pubescens forests was the highest, and P. taeda plantation was the relatively lowest. All these findings suggested the order of water conservation function of soil for 6 forests was: Ph. pubescens forest>C. lanceolata plantation>P. elliotⅡ plantation>evergreen broad-leaved forest>P. massoniana plantation>P. taeda plantation.
