초록

경상남도 진주시 수곡면 시루봉에서 산불이 난 1994년부터 2000년까지 식생회복에 따른 종조성을 조사하였다. 소나무를 비롯한 목본과 풍산포 종자를 가진 초본류는 산불 이후 3년 이내에 왕성한 성장을 보였다. 산화지의 생활형 조성은 H-Dl-R5-e로 다른 산화지와 크게 다를 바 없었다. 산화지 6지점의 평균 종다양도지수는 2.135(1996년), 2.784(1998년), 2.948(2000년)이였다. 6지점의 균등성지수는 1.816(1996년), 2.641(1998년), 1.925(2000년)였다. 천이 분석에서 식생의 회복과 더불어 종수는 증가하여 산화 3년 후에는 주변지역과 거의 유사하거나 약간 높은 지점도 나타났다. 우점도지수 등의 결과에서 추정되는 바는 산불 후 수목의 식재시 산불 후 3년 이전에 실시하는 것이 적합할 것으로 사료된다

The recovery of vegetation in the burned area after forest fire was investigated in Mt. Sirubng, Jinju city, from 1994 to 2000. The floristic composition of a burned area was 37 kinds in 2000. The life from spectra of six sites showed H-D1-R5-e type. This type is similar to the life form which has been usually showed in most of burned areas. Total diversity index of six burned sites showed 2.135 (1996), 3.784 (1998), and 2.948 (2000). whereas, total diversity index of six unburned sites was 2.642 (1996), 2.516 (1998), and 2.723 (2000). Evenness index of six sites showed 1.816 (1996), 2.641 (1998), and 1.925 (2000). The dominant index of burned and unburned areas were 0.012 and 0.250 (1996), 0.031 and 0.261 (1998, and 0.110 and 0.275 (2000), respectively. The degree of succession in the unburned area gradually increased and the burned area was recovered to be similar to the unburned area after three years.
