Abstract

Various environmental parameters change and ecological succession often lead to decline of Pinus densiflora forest in Seoul. Due to decline of it, we proposed the ecological management for conserving and improving from decrease of its dominant area on there. We analysed the P. densiflora forest's classification and suggested its ecological management that based on relation to competition between dominant species in the upper tree layer, the presence of competitive species in shrub layer and vegetation management standard. The Pinus densiflora forest types has been classified 6 types by ecological characteristics. The results from categorized its types are following as; 1) Pinus densiflora pure forest type; edaphic climax Pinus densiflora forest(26.1%), Pinus densiflora pure forest(21.5%). 2) the forest of Pinus densiflora and other species that compete with each other type; Pinus densiflora-Quercus mongolica forest(28.0%), Pinus densiflora-Pinus rigida forest(13.1%), Pinus densiflora-Quercus acutissima(4.2%). We conclude that the results in these kind of 4 types; Pinus densiflora pure forest type where possible to maintain the forest by edaphic climax, human trampling damage, vegetation management(e.x. remove the competition species, shrub layers management etc.) are mainly need to negative management. Whereas, the others 4 types; Pinus densiflora and other species(Quercus variabilis, foreign species, naturalized species etc.) that compete with each other types are need to positive management such as manage the same niche competition species, shrub layers management, remove the foreign species, naturalized species etc.. In these kinds of ecological management are very necessary to maintain Pinus densiflora forest.

외부환경 변화와 천이의 영향으로 쇠퇴현상이 나타나고 있는 서울시 소나무림의 식생환경을 개선하고자 교목층 우점종의 경쟁관계, 하층식생내 경쟁종 출현 유무, 관리정도 등에 근거하여 유형을 구분하고 생태적 관리방안을 제안하였다. 서울시 소나무림을 생태적 특성에 따라 분류하면 소나무순림에 속하는 토지극상림(26.1%)과 소나무순림(21.5%), 소나무와 타 수종이 경쟁하는 소나무-신갈나무림(28.0%), 소나무-리기다소나무림(13.1%), 소나무-상수리나무림(4.2%)등으로 구분되었다. 이들 유형에 대한 정밀한 식생조사 결과, 토지극상, 답압피해, 식생관리로 인해 교목층과 하층에 경쟁종이 출현하지 않아 소나무림 유지가 가능한 4개 군집은 하층식생 보완 등 소극적인 관리가 필요하였다. 반면 교목층과 하층에 소나무와 경쟁수종인 낙엽성 참나무류와 외래종이 출현하는 4개 군집은 생태적 지위가 동일한 경쟁종관리, 하층식생 도입 등 적극적인 관리기법을 적용해야 소나무군집을 유지할 수 있을 것이다.
