摘要
通过对哈思山落叶松人工林的调查 ,选择样木进行树干解析 ,建立胸径与树高、高径比的回归方程 ,进一步得出落叶松人工林前期生长过程 ,分析了人工林林分结构和生长规律 。
By investigating artificial plantation of larix in Hasi mountain and doing stem analysis were set up regression equations of breast diameter, tree height and height-diameter ratio .Was obtained growing process of earlier stage of Larix plantation. Stand structure of plantation and growing regularity were analyzed, that provide a scientific basis for production and management.
