Abstract

A lucidophyllous forest in Kawanaka, Aya, Miyazaki Prefecture, was studied in order to clarify the distribution of the lucidophyllous elements and species richness according to micro-scale geomorphic and the physical-soil conditions. In this area, 5 micro-scale geomorphic units (foot slope, lower sideslope, upper sideslope, crest slope and rocky site) were recognized, and 26 stands for a vegetation survey and 8 plots for a soil survey were investigated. The 26 stands were classified into 5 stand groups according to their microscale geomorphic units. The lucidophyllous elements were assorted into the 8 species groups according to the distributional center of frequency (%) of occurrence and mean coverage (%) of each species along the micro-scale geomorphic gradient. The distributional patterns of the lucidophyllous elements in this area along the micro-scale geomorphic gradient corresponded to those in other areas. It was recognized that in many cases species of the same genus had different distributional centers along the micro-scale geomorphic gradient. Species richness (mean number of species per stand) in each stand group for the micro-scale geomorphic unit ranged from 62.6 to 44.0, and foot slope had the highest species richness which depended on the number of herbaceous plants and lucidophyllous shrubs. On foot slopes, this high species richness seemed to be due to high values of minimum air capacity, indicating highly developed soil conditions.
