| 摘 要： | 根据林分起源不同考察林分树种结构和林龄结构面积、蓄积、单位蓄积2个调查期的发展动态，然后再根据起源不同，林分结构按树种结构、林龄结构两向分组交叉组单产，进行动态分析和比较，以指示林分起源不同，结构所产生的变化表征的消长规律。

| Abstract: | According to the different origination, the development trend of species frame and forest age frame, area, volume, unit volume during two periods of investigating were examined. Stand frame which was divided into two cress group of species frame and forest age frame was dynamicly analyzed and compared. In order to instruct the different origination of stand and the regular of change from frame. |
