一、前言本次判读研究根据森林生态学原理,应用多元统计分析理论,以航片判读为手段,配合少量的样地调查。弄清了某些对飞播林蓄积量影响显著的立地因子(主导因子)。以便准确合理地区划立地条件,为林场非飞播林地区人工造林划分立地条件提供依据,以达到充分发挥地力,科学经营管理森林资源 I. Introduction This interpretation study is based on the principles of forest ecology and applies the theory of multivariate statistical analysis to aerial photos interpretation as a means to cooperate with a small amount of sample surveys. Clarified some of the site factors (dominance) that had a significant impact on the stocks of aerial seeding. In order to accurately and reasonably divide the site conditions, provide the basis for afforestation site allocation in non-aerial seeding areas in order to achieve full utilization of the soil resources, scientifically manage and manage forest resources
