【摘要】 将伊春林区落叶松人工林的调查资料,按不同的坡向和坡位分成六个立地类型组,分别建立立地质量数量化模型,并对伊春林区的落叶松人工林的主要立地类型进行立地质量评价。不同的立地类型组的数量化模型,确定了各立地类型组中影响林木生长的主导因子及各因子的得分贡献。更多还原

【Abstract】 This paper introduces six groups of site types divided according to different aspects and slopes and the establishment of their quantified site quality models based on the survey in formation of the larch plantations in Yichun forest area.It also gives the evaluation to the site duality of the main types of sites of larch plantations in Yichun forest area.The quantified models for different groups of site types determine the scoring contribution of each factor and the leading factors impacting tree growth in each group of site types.更多还原
