采用样带法，以海南岛霸王岭林区典型的热带针叶林与阔叶林交错区为研究对象，分析不同群落类型环境因子变化特征及研究区域内环境因子的综合特征。结果表明：随着林分经针阔交错区的变化，土壤 pH、土壤有机质含量、全氮含量、有效氮含量、有效磷含量和有效钾含量都表现为阔叶林区＞针阔交错区＞针叶林区，全钾含量、凋落物厚度和群落类型光因子表现为针叶林区＞针阔交错区＞阔叶林区，土壤含水量、全磷含量和土壤砂砾含量变化不显著；3种群落类型环境因子的相关性分析表明，除土壤含水量和全磷含量与其他环境因子之间无显著相关外，其他因子间都显著相关；3种群落类型环境因子的主成分分析表明，土壤 pH、土壤有机质含量、凋落物厚度和光因子对第1轴的贡献最大，全氮含量和有效磷含量对第2轴的贡献最大。

Based on 13 typical tropical coniferous-broadleaved forest ecotones, we analyzed the environmental characteristics along/of ecotones using belt transect method. The results showed that,as the stand changed from coniferous forest zone to broadleaved forest zone across coniferous-broadleaved forest ecotone,soil pH,soil organic content,total N, available N,available P,and available K contents showed an order of broadleaved forest zone>coniferous-broadleaved forest ecotone > coniferous forest zone. The total K,litter depth and light factors showed an order of coniferous forest zone>coniferous-broadleaved forest ecotone>broadleaved forest zone,total P. The soil water content and soil gravel content had no significant differences over the different ecotones. In consideration of all these environmental factors studied,Pearson’s correlation analysis showed that the all environmental factors had obvious correlations with each other except for soil water content and total P that had no obvious correlations with other environmental factors. Principal component analysis showed that soil pH,soil organic content,litter depth,and light factors took more effect to the first axis,whereas total N and available P took more effect to the second axis. They were all the main determinants for the distribution of the three different stand zones.
