在森林土壤学中,森林土壤的生产力评价问题仅是近年来开始研究的。评价这个问题是复杂的,它既受到大量生长的林木和多种多样的自然因素的制约,而且到目前为止还缺少土壤肥力和林分生产力通用准则的指标。因此,评价森林土壤的很多方法问题还未解决,尚需要进行广泛的试验研究。 森林群落的特征是生活周期长。研究自然土壤肥力、土壤深层的生物学循环等等,要排除农业土壤的评价方法机械的运用在林业上。森林土壤的评价具有独立的科学任务,是提高森林生产力极其重要的条件。因此森林土壤的评价应该依赖的手段和方法不仅有土壤学和农业化学,而且还有森林学、测树学、经济学和数学。
In forest soil science, the assessment of productivity of forest soils has only started in recent years. Assessing this issue is complicated by the fact that it is constrained by the abundance of trees and a host of natural factors, and so far there is a lack of indicators of common guidelines for soil fertility and stand productivity. Therefore, many methods for evaluating forest soils remain unresolved and extensive experimental studies are still needed. Forest communities are characterized by long life cycles. Study of natural soil fertility, deep biological cycle of soil, etc., to exclude agricultural soil evaluation method of mechanical use in forestry. Evaluation of forest soil has its own scientific task and is an extremely important condition for improving forest productivity. The means and methods by which forest soils should be evaluated depend not only on pedology and agrochemicals, but also on forestry, tree-finding, economics and mathematics.
