利用2012年和龙林业局森林资源规划设计调查样地数据，从龄组结构、树种结构和径阶组结构进行统计分析，结果表明：全局以中龄林、近熟林为主；各龄组株数随径阶增大而递减，株数集中在小径阶组和中径阶组；红松、云杉等珍贵针叶树种和水曲柳、胡桃楸、黄檗、怀槐等珍贵阔叶树种资源偏少。针对林分具有异龄、复层林结构、珍贵树种少、林分株数密集的特点提出了经营建议。
利用2012年和龍林業跼森林資源規劃設計調查樣地數據，從齡組結構、樹種結構和徑階組結構進行統計分析，結果錶明：全跼以中齡林、近熟林為主；各齡組株數隨徑階增大而遞減，株數集中在小徑階組和中徑階組；紅鬆、雲杉等珍貴針葉樹種和水麯柳、鬍桃楸、黃檗、懷槐等珍貴闊葉樹種資源偏少。針對林分具有異齡、複層林結構、珍貴樹種少、林分株數密集的特點提齣瞭經營建議。

The analysis was carried from the age group structure, species structure and diameter-class groups structure by using forest resources design and investigation sample plot data of Helong Forestry Bureau in 2012.The result showed that Helong Forestry Bureau relyed mainly on immature timber and near-mature forest.The number of seedling reduced along with the increase of diameter class.The number of seedling was focused on small diameter class and middle diameter class group.The resource of coniferous species Pinus koraiensis and Picea asperata and broad-leaf species Fraxinus mandschu-rica, Juglans mandshurica, Phellodendron amurense and Maackia amurensis was few.The management suggestion was raised aim at the forest stand characteristic of uneven-aged, multi-storied forest structure, less precious tree species and intensive stand number.
