五、主要树种的成林特性在此,我们从幼树产生到成林的整个过程就天然林的三种主要构成树种(槲树、蒙古栎、五角枫)的幼树的产生与消长,从株数、生长、成林环境三个方面来测定林床状况与日照量等因子,以分析海岸林成林所需要的时间。成林木则主要通过树干解析来研究其生长过程。六、幼树的消长与生育
Fifth, the characteristics of the main tree species into the forest Here, we from the sapling to the whole process of the formation of the natural forest of the three main tree species (Quercus, Quercus mongolica, Pentagon maple) the emergence and decline of saplings from Number of trees, growth, forest environment into three aspects to determine the state of the forest bed and the amount of sunshine and other factors in order to analyze the forest Lin Chenglin the time required. Forest trees are mainly through the trunk analysis to study the growth process. Sixth, growth and decline of young trees and fertility
