摘　　要：该文以群落代表性种群空间分布信息为切入点,利用Max Ent模型拟合种群适宜生境,再结合Arc GIS平台完成海南热带山地雨林的空间分布数据获取,尝试探索一种快速、准确、大面积获取植被分布数据的方法。结果表明:不同代表性种群适宜生境模型拟合精度均高于0.98,拟合结果可靠性高,海拔和温度是种群分布的主要环境影响因素;热带山地雨林空间分布范围预测结果良好,通过比较霸王岭、鹦哥岭、尖峰岭、吊罗山等地区的山地雨林分布特征,明确了海南热带雨林国家公园内山地雨林总面积约612.68 km^(2),分布海拔区间为600m~1480m。该文在植被分类和空间分布范围获取方面做了一些新的尝试,期望可为森林植被的精确分类、快速获取以及保护修复工作提供参考。Vegetation classification and spatial distribution data acquisition are the basic work of vegetation ecology research and one of the most complex ecological problems.In this paper,the spatial distribution information of the representative population of the community is taken as the starting point,and the MaxEnt model is used to fit the suitable habitat of the population.Combined with the ArcGIS platform,the spatial distribution data of the tropical Montane rainforest in Hainan are obtained,and a fast,accurate and large-scale method for obtaining vegetation distribution data is explored.The results showed that the fitting accuracy of the suitable habitat models of different representative populations was higher than 0.98,and the reliability of the fitting results was high.Altitude and temperature were the main environmental factors affecting the population distribution.The prediction results of the spatial distribution range of tropical montane rainforest are good.By comparing the distribution characteristics of montane rainforest in Bawangling,Yinggeling,Jianfengling and Diaoluoshan,it is clear that the total area of montane rainforest in National Park of Hainan Tropical Rainforest is about 612.68 km^(2),and the distribution altitude range is 600m~1480m.In this paper,some new attempts have been made in vegetation classification and spatial distribution range acquisition,which is expected to provide reference for accurate classification,rapid acquisition,protection and restoration of forest vegetation.
