摘要
根据对海南柚木主要栽培区的综合调查材料，以立地指数为因变量，６项生态因子和６项土壤理化性状为自变量，应用数量化Ⅰ、主分量分析及坐标综合评价方法，对海南地区柚木人工林的立地类型划分及立地质量评价，作了定量的科学分析。结果分为４个立地类型组９个立地类型，揭示了该地区柚木生长与各项立地因子之间的关系和规律，对柚木人工林的经营管理及宜林地选择均有参考价值。
According to the investigation data of 32 plots,the site classification andevaluation of
teak forests in Hainan Island were studied.The site index is used as a criterionvariable and the
6 ecological factors are used as explanatory variable in which the soil fertilityis one of the 6
ecological factors,which are determined by the 6 soil chemical characteristics.Through the
mathematical analysis methods of the theory of quantification I,principal com- ponent analysis
and coordinate comprehensive judgment,the 4 site type groups and site typesare classified
and evaluated.
