Abstract

|
|
This study was conducted from April, 1972 to Sep., 1972, in native grassland at Mt. Chun-Ma, Kyonggi-Do, where secondary succession took place.
This survey adopted systematic sampling method and sampled 20 of 20x20 sq. cm.
In each investigation, coverage, density, height, frequency of species were analyzed.
The community structures were analyzed by the summed index {SDR_3(CDF, CFH0\), SDR_4, Ⅳ, PI} and the coefficient of homogeneity (CH_D, CH_C) of main herbs in each investigated sites on the 13th, Oct, 1972.
This community can be said to be that of the Miscanthus sinensis-Arundinella hirta-Carex lancealata association.
The dominant type by the combination of biological types are as follows:
H-D_1-R_3-tu...... Sunned dominance ratio
H-D_1-R_5-tu...... Species %
The seasonal fluctuation of the main herbs in this community can be recognized with the summed dominance ratio, coefficient of homogeneity, and A/F ratio.
