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

对岩手县、秋田县至冲绳县的亮叶林进行了区系调查。根据我们的调查结果，整个日本的透明植物林的植物区系由1066种组成(包括。亚种和变种)。根据美国环境署关系数据库(RDB)标准，将1066种植物分为Ex、DD、A、B、C、D和+7类。对南海岛和各地州1066种亮叶林组成种的分布情况分别进行了统计，并编制成两个表。各县亮叶林组成种的数量与各县冬季低温(最冷月平均气温)呈高度正相关。利用我们的绿叶林植被记录和文献资料，建立了原始或天然亮叶林分布数据库。每株样本树上附生植物的数量与乔木胸径呈高度正相关。附生植物在高寒草本林物种丰富度中起着重要作用。对附生植物的调查结果表明，附生植物是反映高寒草本林原始阶段的最好指标。

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.
