摘要
在森林资源调查中,常规查表法进行小班计算工作量大而易出错,通过对计算方法和构成特点的分析,将树种组用数字代码代替,按调查规程合理使用数字串,通过反复验算调整,编制出源程序,源程序包括形高子程序、2个主程序和2个附加程序,并进行了操作演示。
Subcompartment calculation by traditional routine table checking costs a large amount of work and easily results in making mistakes in the survey of forest resources. Instead, the source program is composed by repetitive tests and adjustments and is conducted operational show. During the course of programming, groups of tree species were replaced by codes based on analysis of the method for calculating and characteristics of composing, and digital bunches were reasonably applied according to operational regulation. This source program includes subprogram of the height, 2 main programs and 2 additional programs.
