宽甸地区不同林型枯落物及土壤蓄水功能研究

Function of Soil Water Storage and Litter of Different Forest Types in Kuandian Area

对宽甸地区几种主要林分类型枯落物及其土壤蓄水功能进行了研究,结果表明:各类型林分枯落物现存量依次为人工纯林>针阔混交林,枯落物持水率为针阔混交林>人工纯林;林分的土壤渗透能力和蓄水能力均为混交林>人工纯林。

The function of soil water storage and litter of several main vegetation types in Kuandian Area were studied.Result shows that the litter of all types of plantation were artificial forest＞ coniferous and broad-leaved mixed forest;the descending order of water holding capacity of litter is coniferous and broad-leaved mixed forest＞ artificial pure forest;the descending order of forest soil penetration capacity ＆water storage capacity are all mixed forest＞ artificial pure forest.
