任良宰 仁川敎育大學校 1969 論文集 Vol.4 No.-
群落周邊部의 生産에 對해서 農業實踐上 關心을 가져온지는 오래이나 그 生産構造나 環境에 對해서 아직 科學的으로 調査된바는 없다. 여기에서 分明해진 �p가지를 들면 다음과 같다. 1. 群落內의 吸光은 葉層이나 非同化器官에 依한 것 外에 群落周邊部에서는 側面으로 부터의 光의 入射를 넣어야 한다. 吸光係數 K 에는 α가 包含되어야 한다. K=KF+Kc/a+α 2. 吸光係數 α는, 葉層이나 非同化器官이 윗面으로부터 遮光하는 量以外, 卽 垂直과 一定한 角을 이루는 側面으로부터의 照射의 效果를 나타낸다. 3. 吸光係數 α값은 上層에서 下層에 移動함에 따라 커진다. 4. C/F의 比는 群落周邊部로 부터 中心部로 向함에 따라서 커진다. 이 값은 大體로 吸光에 奇與하는 C와 F의 役割의 比를 나타낸다고 볼 수 있다.

Mt. Nam (265m), a city park of Seoul, was originally covered with a typical deciduous broad-leaved forests in Central Korea. However, the park forests have been changed the development for various purpose such as the construction of castle wall, road way, broadcasting station, theater, hotel and apartments, in addition, to thoughtless plantation or alien plant introduction. Human population growth from ca. 100 thousands persons less in that time established Seoul as the capital of choseon dynasty in 1394 to ten millions over persons at present, accelerated the vegetational changes of the park. mt. Nam boundary in those days of sunjong (1908) also was much shrinked as much the range of 300 m distance in the northern most to 700 or 800m distance in some places. The actual vegetation of Mt. Nam largely can be classified by floristic composition into two plant communities of Quercus mongolica community and Pinus densiflora community, four plantations of Pinus rigida, Robinia pseudo-acacia, Populus tomentiglandulosa and other tree species, and on mixed forest with native and alien tree species in secondary succession stage (Yim et al. 1987). The restoration movement of Mt. Nam toward to the natural condition of forest or biodiversity is moving now. However, in the movement there are some problems such as the lack of ecological consideration and the undesirable decision of priority in the practice. A warning should be given, especially, on the undesirable plantation of non-native tree species restricting the forest succession, as in the case of southern slope of Mt. Nam. First of all, the most importance in Mt. Nam management is that the restoration for natural forest and biodiversity should be carried on the basis of integrated ecological principles based on the site evaluation.

任良宰,李愚喆 한국식물학회 1976 Journal of Plant Biology Vol.19 No.2
A survey was conducted on the vegetatation of Judo and Gamagseum in warm temperate zone of Southern Korea. They are covered with natural vegetation, evergreen forest dominated with Castanopsis cuspidata in Judo and Machilus thunbergii in Gamagseum. Judo is a small island, ca. 1.75 ha, located within the Wando port. Since the flora of Wando including the Judo was reported in 1924, some investigator have reported evergreen trees of Judo. But the list of plant species of Judo is still unavailable. Gamagseum, located at the 15㎞ north of Judo, is a small island, ca. 1.45 ha, cosisting of two islands, Dae-o-do and So-o-do in low tide, and the report of its flora and any other survey on it is almost none. The vegetations of Judo and Gamagseum are an example of natural forest vegetation occured rarely in warm temperate zone because of human disturbance in the southern coast zone of the Korean Peninsula. However, the ecological study of those vegetation has not ever been made, and the ecological or plant geographical situations of their vegetation is not clear. To determine the vegetation type, listing of plant species in the islands, calculation of basal area of trees over DBH=4.5㎝, Raunkiaer's life form, leaf size class, Pte.-Q and etc., were studied. Total plant species of Judo was 110 species and that of Gamagseum was 99 species. In Judo, Castanopsis cuspidata was 1384 individuals among 2359 individuals over DBH=4.5㎝, and in Gamagseum, Machilus thunbergii was remarkably abundant and Castanopsis cuspidata could not be found.

任良宰 仁川敎育大學校 1963 論文集 Vol.1 No.-
1. 各群叢은 5層 乃至 2層의 層位를 볼 수 있으며 高度에 따라 層位數가 減少되고 있다.. 2. 標高 1,300∼1,500m사이에서 喬木帶와 灌木帶와의 漸移帶를 볼 수 있었다. 3. 大體로 落葉闊葉樹가 優勢하고 針葉樹는 山麓, 稜線과 標高 1,200m 附近에서 볼 수 있었고 常綠樹도 若干있다. 4. 老姑壇 山頂에는 妨害極相을 볼 수 있었고, 高山으로서 野生種以外의 栽培種이 相當數 있다. 5. 標高 500m以下에서는 暖帶性植物인 대나무가 優占種을 나타낸 곳이 많고, 華嚴寺 境內에는 동백나무 群叢을 볼 수 있다. 6. 日本 本州에서의 水溫線과 植生과 關係를 智異山 附近의 50 年間平均(中央觀象臺報)의 것과 比較하여 볼 때, 智異山은 暖帶落葉樹林帶에 屬함을 알 수 있다. 7. 針葉樹는 山麓과 稜線, 傾斜地에 發達하였는데, 이것은 地形의 影響에 依한다는 것 (稜線), 人爲的인 影響에 依한다는 見解(山麓)가 이곳에서는 모두 合當한 것으로 보인 다. 8. 大體로 樹齡이 낮은 樹木이 많으나 優占種은 重要値로 보아 뚜렷하게 나타나 있다. 9. Quercetum serratae, Carpinetum erosae, Pinetum clensiflorae, Ledpedef-etum bicolorae, Miscantheto-sanguisorbetum, Diarrhenetum japonicae 의 群叢을 볼 수 있다. 本 硏究를 進行하는데 있어, 많은 敎示와 文獻을 參考케하여 주신 서울大學校 師範大學 金遵敏 敎授와 智異山 植生의 遷移에 關하여 指導하여 주신 Catholic 醫科大學 朴萬奎 敎授에 感謝의 뜻을 表한다. The Mt. Chi-Ri, 1915 m. heights above sea level, in located in the suothern part of the So-Back mountain chain, and in view of the Hythergraph, it belongs to the deciduous broad-leave forest zone. In Principle, author has studied on the character of vegetation at southwestern vallies of Mt. Chi-Ri from Hwa-um temple to Ro-Go-Dan. Based on the Transect method, a quadrat was provided for this research work, and which was sized to minimum area. According to the importance percentage of overstory, the dominants are captured and named to each associations. Phytographs show the relative importance of dominant species and subdominants in those forest stands. The summary of appeared items in this work are as follows :, 1. The associations are consist of two to five layer of stratifications, and reduced by heights. 2. The econtone between tree and shrub zone are found at the 1,300-1,500m. above sea level. 3. The pinus are abundant at the edge or foot of mountains, and other deciduous non-conifer prevailed to others, And it seems that the reason of conifer prevail at the edge of mountain is due to topographical, and also the conifer is prevailing at the foot of mountain is derived from human influences. 4. There are associations of Quercetum serratae, Carpinetum erosae, Pinetum densiflorane, Ledpedezetum bicolorae, Miscantheto-Sanguisorbetum and Diarrhenetum Japonicze in this research district . 5. In the summit of mountain, a grassland is formed and which is not natural plain zone but a series of secondary succession that perform a kind of disclimax.
