摘要

在对黑龙江省东部水源区5种不同植被土壤层的水分物理性质、蓄水性能、渗透性能以及土壤水分的动态变化进行定位观测分析基础上

对各植被土壤层的水文特征进行了综合比较。结果表明

天然林和灌丛林林地土壤水源涵养能力最强

针叶林地一般

云杉幼林地最差。加强对天然林资源的保护

提高灌丛在当地林木植被资源中的比例

加强人工针叶林林分结构的调整与抚育管理

是提高当地森林植被系统涵养水源功能的有效途径。

Abstract

Based on analyzing soil physical properties

water-holding capacity

infiltration rate and the dynamics of soil moisture of 5 main forest types in east of Heilongjiang province

the hydraulic ecologic effects have been studied comprehensivly.It was indicated that the water resource conservation function of natural forest and shrubs were better than that of the coniferous plantation and young forest.Strengthening the protection of natural forest

enhancing the structure regulation and tending management of coniferous plantation are the effective methods to improve water conservation function.
