一、经营计算图的提出经营计算图是在改进林分密度管理图的基础上提出来的。目前国内外的林分密度管理图均是由等树高线,等直径线,等疏密度线和自然稀疏线四组线列组成。在绘制等树高线和等直径线的问题上,我们认为有两点是值得改进的。其一,等树高线和等直径线由 First, the proposed calculation of business management chart is calculated in the management of improved stand density management chart based on the proposed. At present, the stand density maps at home and abroad are all composed of four groups of line columns, such as tree height line, equal diameter line, density sparseness line and natural sparse line. We think there are two points worth improvement in drawing such as tree height and equidistance lines. First, wait for the tree line and equal diameter lines
