Abstract


PARK, Bong Kyu (Dept. of Biology, Coll. of Education. Ewha Womana Univ.) An ecological study of several grazing grasslands in the branch station of the Taiguan-ryong livestock experiment center. Kor. Jour. Bot. V(3): 1-4. 1962.
A district (Sae-Bong) and 13 district (Sae-Jang Dong) grassland could be dlvided into four type of Community: Miscanthus-Community, Glyceria-Community, Festuca-Community, and Plantago-Community.
Chose 17 or 20 stands from each district A and B and calculated F. I. with the Curtis method, finally vegetational continuum could be recognized while discontinuous boundary line of species distribution could not be recognized.
As a rule the distributional curve of species was binominal or bell shaped. It had a distribution pattern peculiar to itself.
As to the relationship of cattles density and vegetation, I found that the tendency of F. I. moving from small to large paralleled that of disturbance-pressure from weak to strong.
Found that the more the steepness of environmental facters be controlled by a rule "from large to small", the more F. I. might he controlled by a rule "from small to large" and that pH, soil-moisture-content, loss on ignition was in relation with the steepness.
