树高方程的求算是林业生产和科研中的一项广为采用的技术工作。它主要用于导算材积表、研究树高规律、模拟林木有关因子间的相互关系等。过去此项工作多用笔算,从选配曲线到求解参数,计算特征数,常常需要花费大量人力,而且质量难以保证。为此,我们编制了相应的BASIC程序,利用APPLE—Ⅱ微型计算机进行计算,经在生产中应用表明,可比传统笔算提高工效15倍以上,成果的质量也大大提高。该程序结构紧凑,通用性强,可在PC—1500, Calculation of tree height equation is a widely used technical work in forestry production and scientific research. It is mainly used to guide the calculation of volume tables to study the high laws of the tree, simulate the relationship between the factors related to forest. In the past, this work used pen calculations, from matching curves to solving parameters and calculating the number of features, often takes a lot of manpower, and the quality is difficult to guarantee. To this end, we have compiled the corresponding BASIC program, using APPLE-II microcomputer for calculation, the application shows that in the production, compared to the traditional pen-based work more than 15 times, the quality of the results also greatly improved. The program is compact, versatile, available in the PC-1500,
