Abstract
The purpose of this study is to investigate the developmental process of plant community during the secondary succession through the analysis of floristic composition, life form etcectra in burned site, and the structure of forest stand before forest fire occurrence was estimated by the method of anatomical wood identification for dead trees in burned site, Cheisuk-bong in Mt. Chiri of Korea. Plant community before forest fire occurrence was estimated the high mountain conifer stand of the last successional stage to consist of Pinus koraiensis(75%), Abies koreana(15%) and Picea jezoensis(10%), and Betula costata was survived only one species after forest fire occurrence. The total number of plant species in the investigated area was 19 families and 23 species that was identified. The dominate species in burned site were Festuca ovina and Arrhenatherum elatius, Carex humilis, Ligularia fischeri etcectra in the investigated area flora. The life form of plant in burned site was the erect from 47.8%, the tufted from 30.4%, the branched and the prostrate from was both 8.7%, It was assumed that dominant species in the burned sites were Gramineae (Festuca ovina, Arrhenatherum elatius), Carex humilis
지리산(智異山) 제석봉(1,806m)의 산화적지(山火跡地)에서 고사입목(枯死立木)을 조사(調査)하여 산화발생(山火發生) 전(前) 임분(林分)의 구조(構造)를 추정(推定)하였고, 식생(植生)을 조사(調査)하여 종조성(種組成), 생활형(生活型) 조성(組成) 등(等)을 분석(分析)하였으며, 고산지대(高山地帶)에서 산화(山火) 발생(發生) 후(後) 일어나는 식물군락(植物群落)의 이차천이(二次遷移) 과정(過程)을 밝혔다. 산화(山火) 발생(發生) 전(前)의 임분(林分)은 잣나무 75%, 구상나무 15%, 가문비나무 %로 구성(構成)된 극성상림(極盛相林)의 상태인 고산성(高山性) 침엽수(針葉樹) 임분(林分)으로 추정(推定)되었으며, 산화(山火) 발생(發生) 후(後) 유일하게 생존(生存)한 종(種)은 거제수나무 1본(本) 뿐 이었다. 산화적지(山火跡地) 내(內) 식물(植物)은 13과(科) 23종(種)이 출현(出現)하였으며, 식물군락(植物群落)의 조성(組成)은 우점종(優占種)이 김의털(66.5%)이었고, 개나래새(38.9%), 산거울(24.6%), 곰취(21.4%) 등(等) 순(順)이었다. 식물(植物)의 생활형(生活型)은 직립형(直立型)이 47.8%, 속생형(束生型)이 30.4%, 분지형(分枝型)과 2차(次) Rosette형(型)이 각 각 8.7% 등(等) 이었다. 고산지대(高山地帶)에서 이차천이(二次遷移)가 진행(進行)되면서 우점종(優占種)의 변화(變化)는 화본과(禾本科) 식물(植物)(김의털, 개나래새), 산거울
