摘要:

通过对东京城林业局落叶松林的调查,运用数量化理论Ⅰ,根据贡献值排序筛选出主导立地因子为海拔、土层厚度和坡向。用3个主导立地因子把样地划分为16个立地类型区,构建落叶松立地质量评价模型,用这一模型对东京城地区落叶松立地质量进行数量化评价。评价结果表明:16个立地类型可区划分出优、中、差3个等级;经模型检验表明,模型精度达到要求。

关键词: 落叶松, 数量化理论Ⅰ, 立地分类, 立地质量评价

Abstract:

Investigation was carried out in larch plantations growing in Dongjingcheng Forestry Bureau,Heilongjiang Province,China.The main factors affecting the growth of the stands were analyzed by Quantitative Theory I.It was found that the main factors were altitude,soil depth and aspect,respectively.With the 3 leading site factors the stands are divided into 16 site types.Through the establishment of the quality evaluation model of larch plantations,the model is used for appraising the quality of larch plantations in Dongjingcheng,16 site types are divided into 3 categories:excellent,middle and poor.The result of examination of the model indicated that it met the precision requirements.

Key words: larch plantations, Quantitative Theory I, site classification, site quality valuation
