| 摘 要： | 文章以流溪河林场5 种不同林分为研究对象，分析其枯落物和土壤持水特性。结果表明：（1）
5 种林分枯落物持水能力表现为：荔枝（Litchi chinensis）林> 针阔混交林> 杉木林> 阔叶混交林> 毛竹
林；（2）5 种林分0 ~ 60 cm 土壤容重随土层深度增加而增大，60 cm 土层平均容重大小依次为：毛竹林<
针阔混交林< 阔叶混交林< 杉木林< 荔枝林；（3）5 种林分土壤总孔隙度平均大小依次为毛竹林> 针阔
混交林> 阔叶混交林> 杉木林> 荔枝林；（4）5 种林分土壤贮水量大小为毛竹林> 针阔混交林> 荔枝林>
杉木林> 阔叶混交林。总体而言，荔枝林枯落物持水性最好，毛竹林土壤持水性最强。

| Abstract: | In this paper, five types of forest stand in Liuxihe forest farm were selected as research objects
to analyze the water-holding capacity of litter and soil. The results showed that: (1) The water-holding capacity
of litter showed as follows: Litchi forest > coniferous-broadleaved mixed forest > Chinese fir forest > broadleaved
mixed forest > Moso bamboo forest. (2) Soil bulk density in 0 ~ 60 cm depth of five kinds of forest stand
increased with the depth of soil layer increasing. The order in 60 cm was: Moso bamboo forest < coniferousbroadleaved
mixed forest < broad-leaved mixed forest < Chinese fir forest < Litchi forest. (3) The order of the
total soil porosity of five stands was Moso bamboo forest > coniferous-broadleaved mixed forest > broad-leaved
mixed forest > Chinese fir forest > Litchi forest. (4) The order of the soil water-holding capacity of five stands was
Moso bamboo forest > coniferous-broadleaved mixed forest > Litchi forest > Chinese fir forest > broad-leaved
mixed forest. In general, the water-holding capacity of litter in Litchi forest was the best, and the water-holding
capacity of Moso bamboo forest was the strongest. |
