基于黑龙江省穆棱市5个主要树种,对所有样木进行枝条解析从而获得树叶的生物量数据。把树冠分为上层、中层和下层,分别研究探索三层的树叶的生物量与林龄的关系,旨在为进一步分析和探索穆棱市5个主要树种的叶量分布奠定基础条件。结果表明:椴树和红松的三个层次叶量与年龄的相关性都比较显著,对于椴树和红松而言,上层的叶量与年龄的相关性最大,而中层的叶量与年龄的相关性最小,而白桦、云杉、冷杉三个层次的叶量与年龄的相关性则比较低。
Based on the five major tree species in Muling City, Heilongjiang Province, all samples were analyzed for their branches to obtain leaf biomass data. The crown was divided into upper, middle and lower strata. The relationship between the biomass and the age of three layers of leaves was explored respectively. The purpose was to lay the foundation for further analysis and exploration of the leaf quantity distribution of five major tree species in Muling. The results showed that there was significant correlation between age and leaf volume of three levels of lime trees and Korean pine trees. For lime trees and Korean pine trees, the correlation between the upper leaves and the age was the highest, while the middle leaves and the age The correlation between leaf volume and age at the three levels of white birch, spruce, fir is relatively low.
