This study was carried out to provide the basic informations on the sustainable management methods for soil resources by determining the soil physico-chemical properties of specialized plant gardens (Sedum garden, Fern garden, Medicinal plant garden, Ornament plant garden, Rare & endemic plant garden, and Shrub garden) and forest in Korea National Arboretum. Soil particle size showed similar distribution except for Sedum garden and Medicinal plant garden. Soil bulk densities were significantly difference among forest and specialized plant garden (p<0.05) and ranged from 0.79 g/cm 3 in Sedum garden to 1.13 g/cm 3 in shrub garden. Sedum garden and medicinal plant garden showed significantly low of soil moisture content (p<0.05). Soil pH ranged from 4.87 in Sedum garden to 5.41 in rare & endemic plant garden. Soil organic matter content ranged from 2.61% in Sedum garden to 4.71% in forest. The lower value in total N content was 0.11% in Sedum garden and 0.18% in medicinal plant garden. Available phosphorus was significantly lower in Sedum garden and medicinal plant garden than in other specialized plant garden of ranging from 16.90 ppm to 20.34 ppm (p<0.05). The contents of inorganic NH4 + and NO3 - were significantly different among the specialized plant gardens (p<0.05). The ratios of NO3 - to total inorganic N content ranged from 28% in Sedum garden to 44% in fern garden and forest. N mineralization and nitrification rate were also significantly different among the specialized plant gardens (p<0.05).

This study was conducted to provide the basic information for effective conservation and management of coastal forest by analysis the vascular plant in Daewangam park. The vascular plant in Daewangam park was 204 taxa, 73 families, 156 genera, 183 species, 2 subspecies, 4 forma, and 15 varieta. Among them, seashore plants accounted for 6.4% of total plants and they were 13 taxa such as Andropogon ischaemum and Tetragonia tetragonoides, and the Pteridophyte index (Pte-Q) was 0.49. The plants of Compositae, Rosaceae, Graminea, Leguminosae, and Liliaceae showed high distribution. Korean endemic species were 3 taxa such Campanula takesimana, Aster koraiensis and Forsythia koreana. Three rare species of Campanula takesimana, Magnolia kobus and Glehnia littoralis listed as rare plants by the Korea National Arboretum were found in Daewangam park. Naturalized plants were identified 18 taxa including Cerastium glomeratum, Bidens frondosa, and so on, and Naturalization index was 8.8%. The specific species of I～V grades by phytogeography were 28 taxa including Campanula takesimana, Magnolia kobus, Rubus ribisoideus, and so on.

This study was conducted to provide the basic information for making the plans on reasonable conservation of inland wetlands by analysis the vascular plant and life form at Dongpan and Sannam wetland in Junam reservoir, Changwon City. The vascular plants at Dongpan and Sannam wetland were 162 taxa, 58 families, 130 genera, 148 species, 2 subspecies, 1 forma, 11 varieties, and 117 taxa, 45 families, 97 genera, 107 species, 1 forma, and 9 varieties, respectively. The Pte-Q (Pteridophyta Index) was 0.31 at Dongpan and 0.43 at Sannam. The endangered plants by designated Korea Forest Service were 3 taxa including Euryale ferox, Aristolochia contorta and Hydrocharis dubia. The specific plants by floristic region were 11 taxa at Dongpan wetland, and 8 taxa at Sannam wetland. The naturalized plants were 28 taxa including Rumex crispus, Phytolacca americana at Dongpan wetland, and 12 taxa including Lepidium apetalum, Erigeron annuus at Sannam wetland. Therophyte by life form had the highest ratio at two wetlands. Hydrophyte at Dongpan and Sannam wetland were 22 and 21 taxa, respectively.

우리나라의 을릉도에 자생하고 있는 우산고로쇠나무를 대상으로 흉고직경급별 수액 채취량과 수액 내 성분을 분석하였다. 우산고로쇠나무의 총 수액채취량은 376l 이었으며 흉고직경이 증가할수록 수액 채취량도 많았으며 총채취량에 대해 소 중 대경목이 각각18%, 32%, 50%의 비율을 나타내었다. 수액 채취량은 온도와 밀접한 관계가 있으며, 많은 양의 수액이 채취된 날의 기상조건은 일최고 최저기온의 온도격차가 크게 나타났다. 우산고로쇠나무 수액내의 고형분, 회분, 당도는 각각 3.04%, 0.06%, 3.06%로 나타났으며, 유리당은 자당 (30.6 g/l)이 높은 함량을 나타내었으나 포도당, 과당, 맥아당은 검출되지 않았다. 우산고로쇠나무 수액은 총 7종의 무기성분중 칼슘 (522 mg/l)과 칼륨 (309 mg/l)의 함량이 높은 것으로 나타났다.
