摘要

水土保持林对天然降雨起着截流、吸收的作用。系统研究了试验区内马尾松林、湿地松林、板栗林以及马尾松+板栗混交林的冠层、枯落物层及土壤层的水文效应。结果发现

不同林分在这3个方面均表现出差异。(1)林冠层截留量针叶林大于阔叶林

针阔混交林居中

其顺序为:湿地松林>马尾松林>针阔混交林>板栗林。(2)林下枯落物层有效拦蓄量和土壤蓄水功能阔叶林大于针叶林

针阔混交林居中

其顺序为:板栗林>针阔混交林>马尾松林>湿地松林。通过3个层次水文效应研究

揭示出营造和经营管理水土保持林时

应促使3个水文层次功能的同时优化

尽量营造针阔混交林

增加植被层次结构的复杂性

既要发挥针叶林林冠层截留效应

又要发挥阔叶林枯落物层和土壤层的涵养水源功能。

Abstract

Rainfall can be intercepted and assimilated by soil and water conservation forest.Based on the ana- lyses of hydrological effects of canopy

litter fall

and soil for different stands such as Masson pine

Pinus elliotii

Chinese chestnut

and Masson pine &.Chinese chestnut mixed forest

the study showed that in terms of the interception amount of forest canopies

stands ranked in the descendant order of Pinus elliotii

Masson pine

needle-board leaf mixed forest

and Chinese chestnut.Stands

in terms of the effective inter- ception amount and water holding of soil for litter

ranked in the descendant order of Chinese chestnut

nee- dle-board leaf mixed forest

Masson pine

and Pi nus elliotii.When planting and managing soil and water conservation forest

the three layer hydrologic function should be optimized simultaneously and a prior con- sideration should be given to the needle-board leaf mixed forest.The forest had a complicated vegetation structure and was propitious to exert interception eff ect of needle leaf forest and headwater conservation function of litter and soil of board leaf forest.
