收获表是表示经营措施相同的同龄纯林的株数、材积、生长量等因子的标准数值按林龄排列的林业数表。而收获预测表作为现实林的简易收获表,所反映的内容则是有大面积实现可能性的森林未来的平均值。这类简化的收获表,主要用来预测森林的生长和收获,以及进行定量间伐和为林业应用数学规划提供依据。收获预测表实际上是通过数学模型来模拟收获预测这样一个系统的实际行为的一种成果。一般认为,根据密度效应规律建立的数学模型进行编表是比较理想的方法,但这需要相当数量的基础资料、一定的理论知识和计算手段。笔者感到,如果生产单位有当地
The harvest table is a table of forestry in which the standard values of factors such as number of trees, volume, and growth of same-age pure forests of the same management measure are arranged according to age. The Harvest Forecast Table, as a summary harvest of the actual forest, reflects the future average of the forest with a large potential for realization. These simplified income tables are mainly used to predict the growth and harvest of forests, as well as for quantitative thinning and provide a basis for the mathematical application of forestry. Harvesting predictive tables are in fact a result of simulating the actual behavior of a system such as harvest forecasting through mathematical models. It is generally believed that the mathematical model established according to the law of density effect is an ideal method for cataloging, but this requires a considerable amount of basic data, certain theoretical knowledge and calculation means. I feel that if the production unit has a local
