一、前言四川大小金川和木里地区是我国主要林区之一,那里蕴藏着大量的云杉和冷杉针叶林。对这两地区的森林,过去很少有人做过测树因子的研究,这次我们就几年来收集到的有关资料,对该两地区云杉和冷杉两树种的形率、形数进行了研究,其目的是为了探讨在不同地区不同树种的树干形数和形率的变化规律,与其相互关系。这一工作不仅在理论上,而且对生产实践具有很现实的意义。过去在我国生产实践中,由于缺乏具体资料,都应用苏联的研究成果,但是,苏联的研究成果在中国西南地区的适用程度如何?这也是值得探讨的问题。为了达到这个目的,我们通过了分析和验证,以便进一步证明苏联学者的研究结论,是否与中国实际情况完全 I. Introduction Sichuan’s Jinchuan and Muli areas are one of the major forest areas in China, where a large number of spruce and fir coniferous forests are stored. In the past two years, there have been few studies on tree-fixing factors in forests in these two regions. This time, on the basis of relevant data collected over the past few years, the shape and number of spruce and fir species in these two regions were studied , Its purpose is to explore the tree species in different regions of different types and the rate of change, with their relationship. This work is of great practical significance not only in theory but also in production practice. In the past, in the production practice of our country, the research results of the Soviet Union were all applied due to the lack of specific information. However, what is the application of Soviet research achievements in southwestern China? This is also worth discussing. In order to achieve this goal, we passed the analysis and verification in order to further prove that the conclusions of Soviet scholars, whether with China’s actual situation completely
