점봉산 일대 천연활엽수림의 군집 유형별 천이지수 추정

초록

Since the forest succession is changing process in the structure and function of a forest for the longperiod of time, the objectivity of the proces could be improved through the development of model or statisticalmethodology. This study was carried out to estimate sucesion index based on climax index and speciesto grasp the information of quantitative sucesional process for the six comunity types in the naturaldeciduous forest of Mt. Jumbong area. The results indicated that Quercus mongolica-Tilia amurensis comunityhad the greatest succession index of 67.5, followed by Abies holophylla-Fraxinus mandshurica comunity with67.4. Juglans mandshurica-Cornus controversa comunity was recorded the smallest value of 60.5. Thesuccession index of overstory tended to increase considerably at the stage of steady state for all comunitytypes except Quercus mongolica-Tilia amurensis comunity. However, The index of midstory hardly varied asto wind-water dispersion type of life form and positively to animal dispersion type at the 5% probability level.On the other hand, the index was not significantly correlated to the species richnes and Shannon's speciesdiversity index.
