The phytosociological study was carried out to investigate the Corylopsis gotoana var. coreana community structural characteristics and soil environment of Mt. Baegun in Pochen. The vegetation data of total 9 relev$\acute{e}$s were analyzed by the Z$\ddot{u}$rich-Montpellier school's method. Three communities of Mt. Baegun were recognized : Corylopsis gotoana var. coreana - Quercus mongolica community, Corylopsis gotoana var. coreana - Carpinus laxiflora community, Corylopsis gotoana var. coreana typical community. The reanalysis to Corylopsis gotoana var. coreana community structural characteristics in south area classified 8 communities by literature. PCA analysis of Corylopsis gotoana var. coreana community distributed in the middle and southern area showed that the Corylopsis gotoana var. coreana community of the Mt. Jiri in the southern area was highly correlated with the one of Mt. Baegun in the middle area.

The plants medicinal resources of Mt. Baegun were investigated 21 times from March 1, 1986 to December 30, 1987. In order to analyze the vegetation of Mt.Baegun area, herb plants structure and distribution. Herb plants of Baegun Mt.consisted of 60 families, 250 species in all, The resourees of important herb drugswere Campanulaceae, Salicaceae, Moraceae, Polygonaceae. Amarantaceae, Plant-aglnaceae, Labiatae, Compositae, Asclepiaclaceae, Leguminosae, Gentianaceae, Liliaceae, lilicaceae, Dioscoreaceae, Caprifollaceae, Ranunculaceae, Lauraceae, LardicaDalaceae, Araliaceae, Solanaceaer Cornaceae, Fagaceae and Rosaeeae. Theherb durgs were eomparatively more than in other mountains in our country.

Evaluations of the fish farm influences on stream water quality may provide basic informations on watershed management to reduce environmental impact due to fish farm development and to conserve stream water quality in forested watershed area. In this research influent, effluent water in the fish farm and stream water qualities around Mt. Baegun area were monitored seasonally for six years and the following results were obtained. Due to the increase of pH in effluent water from the fish farm it was believed that alkalization of stream water can be accelerated by large scale development of fish farms in the forested watershed area. Also, effluent water from the fish farm increase of EC higher than influent and stream water. As a result of regression analyses, pH, EC, DO, water temperature, total amount of cation and anion in influent and effluent water of fish farm show high significance.

This study was aimed to investigate the elevational and seasonal variation of moth diversity of Mt. Baegun-san, Gwangyang-city, Jeonnam. Moth collecting was carried out using a UV light trap at three different elevational sites from September to October 2014 and from April to October 2015 (9 times) except winter. A total of 288 moth species and 1,444 individuals in 15 families were identified. Geometridae (97 species and 740 individuals) were the most dominant in the numbers of species and individuals, followed by Noctuidae (62 species, 193 individuals), Erebidae (52 species, 177 individuals) and Notodontidae (16 species, 111 individuals). Elevational change showed that the lower elevation, the higher number of species and individuals. Seasonal change of numbers of species and individuals showed the M-shaped pattern with June and August peaks. Compared to the previous records from historical literatures, 197 species were newly added and the total moth species richness of Mt. Baegun-san comprised 449 species in 20 families. The Chao 2 estimated number of species using the observed species including unpublished data set was 1,530 species that comprised about 43% of the Korean Lepidopteran fauna. This large number of estimated species requested the more extensive and long-term survey for better understanding of the total moth fauna in this area.

Analysis of fish farm influences on stream water quality may provide basic informations on watershed management to reduce environmental impact due to fish farm development and to conserve stream water quality in forested watershed area. In this research stream water qualities around Mt. Baegun area were monitored seasonally for three years. Due to the increase of pH in effluent water from the fish farm it was believed that alkalization of stream water can be accelerated by large scale development of fish farms in the forested watershed area. As a result of regression analyses, the linear equation of pH of influent and effluent water of fish farm was, pH of effluent water of fish farm = $0.6234{\times}pH$ of influent water of fish farm + 2.6263. Also, the linear equation of electrical conductivity of influent and effluent water of fish farm was electrical conductivity of effluent water of fish farm = $1.7275{\times}$electrical conductivity of influent water of fish farm - 14.007. Negative effects on stream water quality were observed by indications of increase in electrical conductivity and water temperature of effluent water from the fish farm. Decreases in physicochemical indices such as the amount of dissolved oxygen, total amount of cation and total amount of anion in effluent water from the fish farm were also negative aspects in downstream ecology. It is recommended that water purification system as well as environmentally-friendly fish farm design should be incorporated to large scale fish farm development plan in forested watershed area.

The comparison of Corylopsis coreana populations between natural groups and deforestation groups is carried in five regions such as Seungju, Woldeung, Hwangjeon in Suncheon, Myeongseok in Jinju and Mt. Baegun in Pocheon. The number of sprouting per both $100m^2$ and each individual stump were appeared more in deforestation than in natural groups. In contrast, the height and the diameter of individuals by the number of sprouting are higher and larger in the natural groups. The relationship between the floristic composition and vegetation in the two groups of C. coreana populations was not appeared. Corylopsis coreana are propagated sprouting as well as seedling in deforestation groups located an opening area. Because of the powerful environmental adaptability through growth of the sprouting and the seedling in deforestation groups, the population of C. coreana are not extinction of species oneself, and on the contrary are showed expansion of C. coreana population after temporary disturbance.

This study was investigated to tile influences of clearcutting of timber harvesting on stream water quality at a natural deciduous forest catchment within the Seoul National University Research Forests in Mt. Baegun, Chunnam province during the periods of 1993 to 2001. Soil chemical ingredients and stream water qualities were monitored at 13 ha clearcutting site, non-treatment site and included in these catchment nearby. After the harvesting first and End years, the levels of total- N,　and exchangeable ions ($K^+,\;Na^+,\;Ca^{2+},\;Mg^{2+}$) were decreased the values of before　harvesting, and after the harvesting 111th years and eighth years, respectively. But the chemical characteristics of soil were not changed at all. pH of water in the harvesting area was 6.5 in stream water. Among the nutrient, Cd, Pb, Cu, and phosphate were not found, and the level of BOD reached at the level of the domestic use for drinking. Turbidity, odor, taste, $NH_4\;^+-N,\;NO_3\;^--N$, standard plate count, and coliform were also low enough to be used as the domestic use for drinking in the near villagers. Total amount of cation, total amount of anion and total amount of ion in clearcutting site, non- treatment site and included in these catchment nearby were higher than clearcutting site and non- treatment site. But, there was no great difference.
