Abstract

The mushrooms collected at seven areas of Mt. Chiak in 2002 and 2003 were classified to analyse the distribution and species diversity. Frequency (number of mushroom : N), number of species (S), relative species density (RSD), similarity index (C), richness index (R1), variety index (V1), evenness index (E2), and dominance index(D1) were investigated. Total N and S was 143 and 84, respectively. The RSD was 0.179 ~ 0.226 of the 7 areas. The yearly C of the total area (0.213) was 8.2%. more higher than the average C of 7 areas (0.131). The order in the coefficient of variation (CV) of the indicator for 7 areas was N (10.5%) > D1 (9.2%) > V1 (8.9%) > S (8.5%) > R1 (7.4%) > E2 (2.2%). The average R1 of the 7 areas was 5.36 with the range from 4.85 to 6.01, and 16.72 for the total area. The average V1 of the 7 areas was 16.24 with the range from 14.44 to 18.66, and 68.82 for the total area. The average E2 of the 7 areas was 0.95 with the range from 0.926 to 0.982, and 0.819 for the total area. The average D1 of the 7 areas was 0.071 with the range from 0.055 to 0.073, and 0.081 for the total area. The correlation between N and 5 kinds of diversity indicator (S, R1, V1, E2, D) was not statistically significant, but the correlation between R1, E2 and D1 was statistically significant each other.

치악산 지역의 7개 세부조사구에서 2002~2003년도에 수집 분류 동정된 버섯은 총 53속, 84종, 143개체이었다. 지역 간 중복 발생된 버섯은 총 43종이었으며 이중 2개 및 3개 구역에서 중복 발생된 버섯은 2002년 12개 및 3개종, 2003년 7개 및 4개종이었다. 상대 종 밀도지수(RSD)는 7개 구간에서 0.179~0.226 범위 이었으며 종 다양성 지표 중 유사도(Similarity index: C)는 지역(7개 조사구)간 11.3%~15.9% 범위이었고 평균 13.1% 이었다. 조사지역 전체의 버섯발생은 같은 시기에 인근 지역에 중복 발생할 가능성이 있는 지역 간 유사도보다 다음연도에 동일 지역에서 다시 발생할 가능성인 년차간 유사도가 8.2% 더 높았다. 전체 조사기간의 버섯 종 다양성과 관련된 6가지 지표 중 지역 간 변이계수(CV)는 개체수(10.5%)>우점도 (9.2%)>다양도 (8.9%)>종수 (8.5%)>풍부도(7.4%)>균등도(2.2%) 순 이었다. 버섯 종 다양성 지표 중 풍부도지수(Richness index: R1)는 지역 간 4.85~6.01 범위의 평균 5.36 및 지역전체 16.72, 다양도 지수(Variety index: V1)는 지역 간 14.44~18.66 범위의 평균 16.24 및 지역 전체 68.82, 균등도 지수(Evenness index: E2)는 지역 간 0.926~0.982범위의 평균 0.95 및 지역전체 0.819, 우점도 지수(Dominance index: D1)는 지역 간 0.055~0.073 범위의 평균 0.071 및 지역전체 0.018 이었다. 개체수는 종 다양성 지수들과 유의성 있는 상관관계를 보여주지 않았으나, 종수는 풍부도, 다양도 및 우점도 지수와 유의성 있는 상관관계가 있었다. 종 다양성 지수 간 상호 유의성 있는 상관관계를 보여주는 지수들은 풍부도와 다양도 및 우점도이었다.
