本文报道应用计算机技术研制供造林设计使用的计算机造林设计系统,以辅助福建省闽北地区五个主要用材树种造林设计。本系统由各树种多种模型组成,采用Basic语言编程序,以Apple-Ⅱ型带汉字系统的微型机为工具,包括一个主程序和五个子程序。对于本系统,只要输入有关立地因子、经营水平,计算机经一系列数学模型运算与方案比较,即可打印出各树种在合理造林密度下的生长表,并打印出造林设计表,供林业工作者参考使用。
This paper reports the application of computer technology to develop a computer-aided design system for afforestation design to assist afforestation design of five major timber species in northern Fujian. The system consists of a variety of models of various species, the use of Basic language programming, Apple-Ⅱ type system with Chinese characters as a mini-tool, including a main program and five subroutines. For the system, as long as the input of the site factors, business level, the computer through a series of mathematical model operation and program comparison, you can print out the tree growth of reasonable planting density table, and print out afforestation design table for forestry workers Reference to use.
