传统收获表是指某一树种在特定地区和管理体系下，以立地条件和年龄为变量描述林分平均生长过程的数表．林分密度管理图是根据林分密度效果编制的可预测林分平均收获的图．通过与传统收获表和林分密度管理图的概观比较和探讨，该文系统地阐述了系统收获表的概念和功能．系统收获表的基本特点是为预测现实林分在不同立地条件和管理体系下生长过程的计算机程序．因此，系统收获表能描述在多维变量（如年龄、立地条件、林分密度、胸径和树高）条件下的现实林分和单木的无数生长过程
Traditional harvest table refers to a species in a particular area and management system, site conditions and age as a variable to describe the average growth process of the table. The stand density management map is a diagram of the average forecasted stand yield based on the stand density effect. Through the comparison and discussion with the traditional harvest table and stand density management chart, the article systematically expounds the concept and function of the system harvest table. The basic characteristics of the system harvest table is to predict the actual stand in different site conditions and management system of the growth process of the computer program. Therefore, the system revenue table can describe the actual growth of trees and single wood under the conditions of multidimensional variables (such as age, site conditions, stand density, DBH and tree height)
