This study was conducted to investigate changes on burned areas after a forest fire in Geyjoksan which occurred in April 2000. Both soil physicochemical properties and vegetation present were analyzed in burned and unburned sites of pinus densiflora according to two slope aspects(south and north-facing slopes). The results of the analysis are as follows. The appearance species of vegetation were 21, 15 and 18 for burned site, burned site-1 and burned site-2 of pinus densiflora community respectively, indicating that the occurrence of forest fire and slope aspects affect vegetation appearance. The pH values at 0~10㎝ soil depth of unburned and burned sites of pinus densiflora community were 5.04 and 5.12 respectively with no significant difference between them. Mean organic matter, total nitrogen and available P also had no significant difference. This results indicate that the forest recover its former pH, total nitrogen, mean organic matter and available P over time after a forest fire. North-facing slope had relatively higher soil water content thus implying that its pH values of soil lower than south-facing slope. On the other hand, south-facing slope had high organic matter and available P content of soil as compared to north-facing slope. With south facing slope having high water contents, humus was accumulated due to slow organic matter decomposition. The pH values also decreased due to organic acids from humus. However, we observed that organic matter and P concentration in soil increased.

본 연구는 남해군 금산에 분포하고 있는 식생의 구조를 파악하기 위해 2014년과 2015년에 실시되었다. 본 연구조사지의 식생을 식물사회학적 방법과 DCCA ordination으로 분석한 결과, 10개의 자연림(졸참나무군락, 개서어나무군락, 신갈나무군락, 소나무군락, 곰솔군락, 소사나무군락, 굴참나무군락, 느티나무군락, 서어나무군락, 히어리군락)과2개의 식재림(편백군락 및 삼나무군락)으로 구분되었다. 또한 복곡저수지 아래 계곡부에는 환경부지정 보호야생식물인히어리가 아교목상으로 군락을 형성하고 있었으며, 복곡저수지 인근 천하저수지 위쪽 임도에서는 끈끈이주걱이 발견되었다. 식재림을 제외한 전체 군락에서 나타난 중요치는 졸참나무가 가장 높았으며(45.7), 중요치가 높은 주요 종에 대한 흉고직경급을 분석한 결과 졸참나무, 신갈나무 및 개서어나무는 정규분포형을 나타내고 있어 현재의 우점도를 유지할 것으로 보인다. 연구대상지내 군락의 토양을 분석한 결과, 평균 토양 pH는 4.28∼4.76으로 나타났다. DCCAordination 분석 결과, 졸참나무군락은 해발고와 상관없이 고르게 분포하는 것으로 나타났고, 곰솔군락 및 소나무군락은 다른 군락들 보다 해발고가 낮고 남사면에 주로 분포하였다. This study was conducted to classify the vegetation structure of the Geumsan in Namhae-gun. Using the phytosociological method and DCCA ordination, the vegetation was classified into 10 communities of natural forests (Quercus serrata, Carpinus tschonoskii, Q.mongolica, Pinus densiflora, P.thunbergii, C. turczaninowii, Q. variablis, Zelkova serrata, C.laxifora and Corylopsis gotoana var. coreana) and 2 communities of plantation forests (Chamaecyparis obtusa and Cryptomeria japonica). Among the communities other than the plantation forests, the importance value of Q. serrata (45.7) was found to be the highest . According to the results of DBH analysis among the species with high importance values, Q. serrata, Q. mongolica and C. tschonoskii showed normal patterns in the size-frequency distribution, suggesting that these species will continue to hold their current dominance. The average soil pH in the communities ranged from 4.28 to 4.76. The results of DCCA ordination analysis showed that Q. serrata was evenly distributed in the high and low elevation habitats. P. thunbergii and P. densiflora communities were mainly distributed in the lowest elevation habitats on the southern slope.

This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.
