摘要:
作为陆地生态系统的主体,森林对地表圈层的水循环产生了重要的影响,其涵养水源、防止水土流失和维持水质的作用为多数学者所公认,但是对于森林是否增加或减少河川径流量,在学术界还存在较大的争议。作者根据国内外学者在森林水文效应方面的观测结果和理论分析,提出了森林植被的水分自营作用理论。该理论认为,森林具有对环境的正向改造作用,森林植被通过对林区水分分布场的自主营造(改造)机制来增加林地的有效水分供应,改善林区的水文气象环境,创造出有利于森林植被生存的条件,同时引起河川径流量的增加或者降低。森林植被的水分自营作用理论比较好地综合了森林影响径流形成的各个因素,能够统一解释森林水文效应中相互矛盾的试验结果。...
Abstract:
As the main body of the terrestrial ecosystem，forests play an important role in the water cycle of the epigeosphere. It is generally acknowledged by the scholars that the forest has such ecological functions as water and soil conservation，water resources conservancy and water quality improvement. However，it is still controversial in the academic circles whether forests increase or decrease the stream flow. Based on the extensive domestic and foreign observation and theoretical analysis in the field of hydrological effect of forest，a hypothesis which is called water selfsupporting effects of forest was propounded. The hypothesis holds that forests can postively improve water environment. Forest vegetation can add available moisture supply to woodland，modify the forest hydrometeorological conditions，and create favorable living conditions for plant survival through selfbuilding/adjusting the water distribution of the forest ecosystem，leading to the increase or decrease of the river runoff. The hypothesis synthetically consider the various factors affecting runoff formation in forest ecosystem and also can systematically explain the contradictory experimental results in hydrological effects of forest. To further understand and perfect the theory and contribute to forest hydrological effects assessment，some experiment verification methods，such as accurate measurement of radiation energy and water flux in typical forest，researches on distributed forest watershed evaporation calculation model，studies on the key links of the water selfadjusting effects of forest and its quantification，analysis on water selfadjusting relations in forestland，and hydrological process simulation of forest ecological system，were proposed.
