落叶松人工林密度效应及优化选择研究

The research of Manmade larix Gmelinii Forest with Density Effect and Optimization Selection

在标准地数据调查的基础上,经拟合得出落叶松人工林产量密度模型,推算出林分地位指数14-20之间落叶松人工林基准年龄时的最优密度。研究成果对牡丹江地区落叶松人工林合理经营密度的确定提供了科学的理论依据,亦对林业生产具有一定的指导借鉴意义。

This paper on the basis of investigation data in the standard,by the fitting model of manmade larix gmelinii forest with the production of density,calculates the most appropriate standard age density when forest stand site index between14-20. the study result supports the scientific theoretical foundation by which manmade larix gmelinii forest could be confirmed in Mu Danjiang region,and has some certain guiding significance to the forestry production.
