The purpose of this study is to clearify the role of the forest in the thermal and water interaction between atomosphere and ground, the specific results of the study are as follows.1 The process of the CO2 and H2O exchange between trees and the atmosphere through individual leaves was investigated using a porometer, As a result, the effects of meteorological conditions ton the exchange process of several broad-leaves tress could be estimated.2 The process of the CO2 and H2O exchange between the forest and the atmosphere at a community level using the eddy correlation technique. The effects of meteorological conditions on the conductance of young forests and Hinoki forests are discussed.3 Forest soil have barious porous structures, which contribute to its unique water retention and permeability. In order to quantitatively estimate the porous structures and moisture characteristics of forest soil, the lognormal distribution was adopyed, good results were obtained.4 In order to clearify the hydrochemical development mechanism along with the forest sccession, the changes in pH and CO2 found at different successional stages of forest and soil depth was discussed.

本研究的目的是明确森林在大气-地面热、水相互作用中的作用，具体研究结果如下：1.利用气孔计研究了树木通过叶片与大气之间的CO2和H2O交换过程。研究了气象条件对几种主要大气污染物交换过程的影响，2.利用涡度相关技术研究了群落水平上森林与大气之间CO2和H2O的交换过程。讨论了气象条件对幼龄林和扁柏林电导率的影响。3森林土壤具有多样的孔隙结构，这有助于其独特的水分保持和渗透性。为了定量评价森林土壤的孔隙结构和水分特征，采用对数正态分布，取得了较好的效果。4为了阐明森林水化学沿着的发展机制，讨论了不同森林演替阶段和土壤深度的pH和CO2的变化。
