An Application of Analysis of Concentration for Ecological Study of Foliose Lichens

엽장지의식물의 생태학적 연구에 대한 집중도분석법의 적용

Lichen communities at the Duckyoo National Park were studied by the analysis of concentration. Thirty three species of lichen identified were divided into three vegetational groups and fourty two stands into three environmental groups by sum of square algorithm. The sharpness of the nine blocks table is low, that is C=0.05, which means the divergency of lichen communities to be high. The result reveals that canonical first variate is 0.313 (91%) and second variate 0.100 (9%), and calculates the expected deviation from the first variate. The intermediate zone of environmental group is more important area to distribute lichen species than other zone. The computer program for this study was made by APPLE SOFT BASIC (DOS 3.3).
