【摘要】 本文根据日本落叶松人工林林分蓄积量、生产力与林龄、立地条件、林分密度等因子的关系,选取21个样地,采用标准地调查、树干解析方法对其人工林的蓄积量、生产力以及与立地条件之间的关系进行了较为系统的研究。研究表明:日本落叶松人工林在四川盆地中山地带生长良好,林分生产力与林分所处立地条件、林分密度、经营管理等密切相关。更多还原

【Abstract】 Based on the relations of factors of Japanese larch atand such as stand volume,productivity and age,site conditions and stand density,21 plots are selected,aiming at researching into the relation between its productivity and its site conditions.The results have indicated that Japanese larch plantations grow well in medium mountain areas of the Sichuan Basin,and its stand productivity,site conditions,the stand density and management are closely connected.更多还原
