1.长白山露水河施业区主要有属于四个土类的六种土壤。它们在分布、剖面性态和森林植物性质(化学性质、物理性质和水分状况)等方面有着明显的差异。2.林型的分布和土壤的森林植物性质,特别是和水分条件有着非常密切的关系,每种土壤上都有自己特定的原生林型。3.在不同的土壤上和不同的林型中,树种的分布有明显的规律性。树种分布的广狭在一定程度上反映了它们对于土壤水分条件和其他性质的相对适应能力。4.当地几种主要树种的生长状况与土壤条件有着非常密切的关系。看来,对于当地的具体土壤和树种来说,在土壤因素中,水分起着最主要的作用,其次为养分。5.对于当地的林业实践来说,如何应用抚育、采伐和其他经营措施,使偏干而不够肥沃的土壤保持水分和养分,使偏湿的土壤减少水分和促进水分的消散,是一个重要的任务。
1. Changbai Mountain Lushuihe Shi mainly four soil belonging to four types of soil. They have obvious differences in distribution, profile and the nature of forest plants (chemical, physical and water conditions). 2. The distribution of forest types and the nature of the forest plants in soil have a very close relationship with the water conditions, and each soil has its own specific primary forest type. In different soil and different types of forest, tree species distribution has obvious regularity. The wide distribution of tree species reflects to some extent their relative adaptability to soil moisture conditions and other properties. 4. The growth of several major tree species in the local area has a very close relationship with soil conditions. It seems that for the specific soil and tree species on the ground, water plays a major role in soil factors, followed by nutrients. 5. For local forestry practices, how tending, harvesting and other management practices are applied make it important for dry and less fertile soils to retain moisture and nutrients so that moisture-poor soils can be reduced and dissipated task.
