摘 要:用全省范围内调查所得的220块标准地作为编图、检验材料,以林分密度效应规律为基础,根据湿地松林分密度与林分各测树因子之间的数量关系,建立各种数学模型,编制出广东省湿地松人工林密度管理图。经精度和适用性检验表明,该图的编制精度达94%以上,适用性F检验差异不显著。This paper discusses the compilation methods of management density map of slash pine plantations in Guangdong province. The map is compiled by some of the mathmatical models that is established according to the quantiative relations between the stand density of slash pine and the different factors of tree measuration, on the basis of data of 220 plots of slash pine in Guangdong, and the law of stand density effect. The results show that the accuracy is above 94%, and there is no significant by fitness testing. The map is suitable for using in practice.
