森林水量平衡是研究森林植被中水分的运动规律,对水分的收入和支出系统进行定量分析。水是森林生态系统中能量和物质循环的主要载体,也是影响森林生产力的重要的生态因子。研究森林水量平衡可以比较全面地认识水的分配状况,以揭示水在运动中所具有的各种形式之间的内在联系,从而使森林生态环境朝着人们所期待的方向转化。 森林水量平衡国内外很多学者曾进行过广泛的研究(William等,1967;中野秀章,1976; Forest water balance is to study the law of movement of water in forest vegetation, quantitative analysis of water income and expenditure system. Water is the main carrier of energy and material circulation in forest ecosystem and also an important ecological factor that affects forest productivity. Studying the balance of forest water volume can fully understand the distribution of water in order to reveal the inherent relationship between various forms of water movement and to transform the forest ecological environment in the direction expected by people. Forest water balance Many scholars at home and abroad have conducted extensive research (William et al., 1967; Nakano Hideo, 1976;
