Making of the database for the lucidophyllous forests related to biodiversity andconservation of those h-eats.

对岩手县、秋田县至冲绳县的光叶林植物区系进行了调查。调查结果表明，日本光叶林的植物群由1066种（包括1000种）组成。亚种和变种）。根据环境厅RDB（ed.）的分类标准，将1066个组成种分为Ex、DD、A、B、C、D和+7类。调查了各都道府县和南西诸岛的1066个光叶林组成种的分布，编制了两个表，各地区光叶林的组成物种数与冬季低温呈高度正相关（最冷月份的平均气温）利用我们的森林植被记录和文献资料，建立了原始或天然光叶林分布数据库。各样地的附生植物数量与光叶树种胸径（cm）呈高度正相关。附生植物对明叶林的物种丰富度起着重要的作用。通过对附生植物的调查，认为附生植物是反映明叶林原始阶段的最佳指示植物。

Floristic investigation of the lucidophyllous forests from Iwate and Akita Prefectures to Okinawa Prefecture was conducted. As the results of our investigation, it has become clear that the flora of the lucidophyllous forest throughout Japan consists of 1066 species (incl. subspecies and varieties). 1066 component species were classified into 7 categories (Ex, DD, A, B, C, D and +) by the criteria of RDB of Environment Agency (ed.). Distribution of 1066 component species of the lucidophyllous forest in every prefecture and in the Nansei Islands was checked and compiled into two tables, respectively.The number of component species of the lucidophyllous forest in each prefecture had a high positive correlation with low temperature during winter (the mean temperature in the coldest month) in each prefecture.The database of distribution of the primitive or natural lucidophyllous forests was made by using our vegetational records of the lucidophyllous forests and literatures. The number of these forest attained 550 points.The number of the epiphytes on each sample lucidophyllous tree had a high positive correlation with lucidophyllous tree DBH (cm). The epiphytes play an important role in the species richness of the lucidophyllous forests. As the results of the investigation for the epiphytes, it is concluded that the epiphytes are the best indicators about the primitive stage of the lucidophyllous forests.
