내장산국립공원에 자생하고 있는 굴거리나무 개체군의 분포와 식생구조를 분석하였다. 굴거리나무 개체군은 내장사지구의 금선계곡과 원적계곡, 백양사지구의 운문암 주변에서 분포하고 있으며, 그 면적은 각각 1.8km2, 0.6km2 이었다. 굴거리나무 개체군의 밀도는 금선계곡 전망대 주변이 가장 높았고, 금선계곡과 운문암 주변에서 비교적 높았다. 굴거리나무는 경사가 급한 전석지대에서 생육하고 있으며, 대팻집나무, 산딸나무, 작살나무와 생태적 적소가 유사한 것으로 생각된다. 식생구조분석 결과 내장산국립공원 산림의 아교목층과 관목층에서 굴거리나무의 우점도가 증가할 것으로 예상된다.

This study was carried out to analysis the vegetation status, the habitat size and the meaning of new natural habitat, and to provide basic data for conservation or management on the newly augmented natural habitat of Abeliophyllum distichum Nakai in Yeoju-si, Gyunggi-do, Korea. A. distichum is a Korean monotypic endemic species. Most natural habitats of A. distichum have been reported in South-Central area around Chungcheong-do. The extent of occurrence of A. distichum can be enlarged to Central area due to the Yeoju-si habitat. The new habitat is located on a hillock which is composed of rock field at $37^{\circ}20{\sim}21^{\prime}N$, $137^{\circ}43{\sim}21^{\prime}E$, and 99~120m a.s.l.. The habitat size is small as about $530m^2$, and a small stream runs aside. The number of individuals of A. distichum was about 1,200. But most individuals were smaller than 0.5m height, so just about 300 individuals are taller than 1.0m height. A. distichum on Yeoju-si seemed to be maintained and distributed by vegetative propagation from elongated roots of branches. Pinus rigida and Quercus aliena dominated tree layer, and Lindera obtusiloba, Q. aliena and Acer tatricum appeared frequently in subtree layer. The shrub layer was dominated by A. distichum with Stephanandra incisa, Euonymus alatus for. ciliatodentatus, Ligustrum obtusifolium, etc. The coverage of herbaceous layer was low.

This study investigated the actual vegetation and plant community structure of Geumsun valley and Weonjeok valley of Naejangsan(Mt.) National Park to provide the data for park management. As a result of analysis of actual vegetation, Quercus variabilis community(47.3%) and Quercus serrata community(17.0%) are widely distributed but Carpinus tschonoskii community(7.5%) and Zelkova serrata community(6.9%) are distributed in valley forests. Plant communities were divided into 6 communities of Fraxinus mandshurica, Carpinus tschonoskii, Carpinus tschonoskii-Platycarya strobilacea-Zelkova serrata, Zelkova serrata, deciduous broad-leaved mixture(Zelkova serrata-Lindera erythrocarpa-Acer palmatum), and Lindera erythrocarpa-Cornus walteri according to the analysis of TWINSPAN of classification using 20 plots($400m^2$). Geumseon valley is composed of boulder stone area of average slope $20^{\circ}$, and there were distributed Fraxinus mandshurica community of 86 years old, Carpinus tschonoskii community in age from 56 to 79, and Carpinus tschonoskii-Platycarya strobilacea-Zelkova serrata community in age from 48 to 71. Weonjeok valley is composed of boulder stone area of average slope $11^{\circ}$, and there were distributed Zelkova serrata community in age from 52 to 71, deciduous broad-leaved mixture community in age from 49 to 70, and Lindera erythrocarpa-Cornus walteri community in age from 43 to 51. Ecological succession of each community was predicted to maintain same state. The Shannon's species diversity showed from 0.8220(Fraxinus mandshurica community) to 1.3850(Carpinus tschonoskii community) per unit area of $400m^2$.

This study was conducted to investigate and analyze the characteristics of the plant community structure of vegetation distributed on the western slope and ridge connecting Mt. Noja to Mt. Gara. This basic research was executed not only to restore and manage forest vegetation, but also to monitor the trend of change in the long term. As a result of classifying the communitise in 86 survey quadrats, the Pinus thunbergii-Platycarya strobilacea comm. and P. thunbergii-P. densiflora comm. were distributed around the lowlands. The Carpinus tschonoskii-Deciduous broad-leaved comm., Styrax japonicus-Deciduous broad-leaved comm., Acer pictum subsp. Mono-Deciduous broad-leaved comm., Deciduous broad-leaved comm., and Zelkova serrata comm. appeared in the valley and all stone areas. Quercus serrata comm., Q. serrata-S. japonicus comm., S. japonicus-Carpinus cordata comm., Euonymus oxyphyllus comm. were classified as being distributed on steep slopes with relatively high altitude. According to the succession trend of the forest, evergreen conifers will be transition to deciduous broad-leaved trees. However, deciduous broad-leaved arboreous forests, such as Carpinus tschonoskii, zelkova serrata, and Acer pictum subsp. Mono, were considered to maintain their current succession stage because not only the stratified structure was developed over about 50 years tree age, but also ecologically stabilized. As environmental factors, it was analyzed that altitude, pH, content of clay and silt, Mg⁺⁺, Ca⁺⁺, etc. directly or indirectly affect the distribution of plant communities.

This study was carried out to evaluate precipitation, geological and topographical factors from the landslide area occurred in Maeri, Sangdong-myeon, Gimhaesi, Gyeongsangnam-do. The landslide was affected by geo-topographical factors. Talus which is infiltrated easily by runoff was widely distributed in the landslide area. Concave areas on back- and toe-slope were built up colluvial materials and weathered soils. The colluvial materials were consisted of less weathered pebbles and stones (diameter: 10~100 cm) which are easily infiltrated during rainfall events. Also the landslide was mainly affected by an ascending of ground water table which is low in summit and high in toe-slope due to geo-topographical characteristics of the landslide area. The most important reason of the landslide was a lacking of drainage system of ground water despite the high infiltration rates of ground water in talus area during rainfall events.
