摘要
森林生态系统是陆地生态系统中重要的组成部分,枯落物又是森林结构中重要的一环,具有涵养水源、拦蓄降水、减少径流、维持土壤湿度、防止土壤水分散失和土壤溅蚀等重要的水文生态功能。研究影响枯落物持水特性的因素,揭示各因素与枯落物持水特性之间的关系,对研究森林的水土保持能力,合理规划和利用水资源方面具有重要的意义。笔者综述了影响枯落物持水特性的重要因素(如森林类型、林分特征和成土因素等),探讨了各因素与枯落物持水特性之间的关系及影响程度,以期为人工林立地环境的筛选、造林树种的配置、以及天然林与人工林的营林措施选择方面提供合理的建议和参考。
Forest ecosystem is a significant part of terrestrial ecosystem.Litter,as an important part of the forest structure,has key hydrological and ecological functions such as conserving water resources,impeding precipitation,reducing runoff,maintaining soil moisture,and preventing soil water loss and soil erosion.Studying the factors affecting the water-holding characteristics of litter and revealing their relationship are of great significance for studying the soil and water conservation capacity of forests and rationally planning and utilizing water resources.In this paper we summarize the crucial factors affecting the water-holding characteristics of litter(such as forest type,stand characteristics and soil formation factors),and discuss the relationship between each factor and the water-holding characteristics of litter and their affecting degree,so as to provide reasonable advice and reference on the selection of forest site environment,the allocation of afforestation tree species,and the selection of forest management measures for natural forests and plantations.
