  • 한국해역에서 알려진 집게류는 12과 57종, 게류는 20과 183종이다. 집게류는 집게과 (Paguridae) (19종)와 넓적왼손집게 과 (Diogenidae) (12종) 의 종들이 많고 게류에서는 물맞이게 과 (Maidae) (33종) 의 종이 가장 asg고 다음이 바위게 과(Grapsidae) (29종), 부채게 과 (Xanthidae) (22종), 꽃게 과 (Portunidae) (16종) , 달랑게 과(Ocypodidae) (16종)의 순이다. 저자는 한국 해역을 동해, 대한해협, 제주도해역, 황해의 4구역으로 나누고, 집게류와 게류를 북방형, 온대형, 남방형의 3분지형으로 나누었다. 집게류의 경우 북방형 9종, 온대형 40종, 남방형 8종이고, 게류의 경우 북방형 7종, 온대형 87종, 남방형 89종이다. 집게류의 경우 동행 29종, 대한해협에 30종, 제주도해역에 30종, 황해에 21종이 게류의 경우 위의 순서대로 62종, 121 종, 104 종, 74종이 분포하며, 각 해역에서의 분포형도 고찰했다. 각 해역에만 분포하는 종의 수는 집게의 경우 동해에 8종, 대한해협에 3종, 제주도해역에 16종, 황해에 0종, 게류의 경우 위의 순서로 8종, 20종 40종, 12종이다. 집게류는 북방형종이, 게류는 남방형종이 비교적 많으며 동해에는 북방형종들이 제주도에는 남방형종들이 비교적 많다. 4구역 중 2 구역 (6조합) 사이의 유사계수(r=a/a+b+c)를 계산한 바 양 분류군 모두 대한 해협과 황해 사이의 유사성이 가장 크고 (집게류 ; 0.55, 게류 : 0.59), 제주도해역과 황해 사이의 유사성이 가장 적다. (집게류 ; 0.20, 게류 : 0.19). 분포상을 이해하기 위하여 각 해역의 환경조건도 알아보았는바, 분포의 양상과 해황과 잘 부합된다.

  • The purpose of this study is to classify the Korean precipitation regions on the basis of the characteristics of extratropical cyclonic precipitation. From now on, extratropical cyclone is called cyclone in short. By using factor analysis and Ward method in cluster analysis, precipitation regions on the basis of the characteristics of cyclonic precipitation are classified The principal data used in this study are daily precipitation records obtained from 60 weather stations of the Korea Meteorological Service during the ten years($1981{\sim}1990$), and weather charts published by the Japan Meteorological Agency. The results obtained in this study are summarized as follows: (1) In the factor analysis using 43 variables which have relation to the extratropical cyclonic precipitations, They are seven factors whose eigenvalues are above 1.0. This explains 86 percent of total amount. The first factor explains the characteristics of precipitation in the middle-west area and its contribution degree has the highest 10.9 percent. (2) According to the cluster analysis method of Ward, extratropical cyclonic precipitation regions are classified seven macro regions(such as Kyungki and North Youngseo, Youngdong and Ullungdo, Hoseo and South Youngseo, Honam and Northwest Chejudo, Southeast Chejudo, North Youngnam, and South Youngnam), 22 meso regions. (3) The characteristics of precipitation regions have relations to the path of cyclone, the direction of air inflow and the strike of mountain ranges. As the conclusion, the Central China Low brings much precipitation in the southern coast and southern area of Korea as moving to the northeastward. The North China Low moves eastward and brings much precipitation in the western area of the Taeback mountain ranges. The probability of extratropical cyclonic precipitation is the lowest in the inland of Yeongnam and the eastern coastal areas which belong to the rain shadow region. Namely, The seasonal and spatial characteristics of precipitation are closely associated with the path of cyclone and the direction of air inflow according to its passage, and the strike of mountain ranges.

  • The Late Quaternary palynoflora from an archaeological site in Piseo-ri, Muan, Korea consists predominately of deciduous broadleaved angiosperms and subordinately of herbs and conifers. Dominant taxa are Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, Alnus, Carpinus, deciduous Quercus, Compositae and Gramineae. The palynoflora dated 43,000-18,000 yr BP, corresponding to the last glacial period, is similar to the modern vegetation of the cool temperate deciduous broadleaved forest in the middle part of the Korean Peninsula. Based on palynofloral composition, three palynozones are recognized. Zone I represents a cool temperate deciduous broadleaved forest, composed of Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, Alnus and D. Quercus, and is characterized by persistent occurrence of warm temperate taxa. Zone II shows drastic decrease in Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, and increase in herbs. This zone reflects a cool temperate deciduous broadleaved forest with scattered open grasslands. Zone III is characterized by dominance in herbs and increase in conifers. The palynofloral composition suggests a cool temperate climate, and variation in occurrences of main taxa indicates that climatic conditions gradually became cold and dry.

  • Textural analysis of gravels of raised beach (old beach) in the Weaver Peninsula, King George Island, Antarctica has been carried out as a first part study among 20 other sites surveyed in the Weaver Peninsula and Barton Peninsula, King George Island. The raised beach described as WP-5 in this paper is 3.95 m higher than the present beach in elevation. And it is described as old beach. The beach shows typical subenvironment, that is, beach berm and beach face. Mean size, mean roundness and mean sphericity of gravels from beach berm are -4.10ø, 0.44 and 0.66 respectively. However, mean size, mean roundness and mean sphericity from beach face are -4.23ø, 0.41 and 0.67 respectively. In particular, it seems to be worthy to note the differences of textural parameters between Antarctic glacio-marine beach gravels and temperate and normal marine beach gravels. Under such conception the present study wishes to show only textural parameters, i.e., size, roundness, sphericity and shape obtained from the analysis of Antarctic glacio-marine beach gravels.

  • Vegetational structure and successional sere were investigated for Paryeongsan Zone in the Dadohaehaesang National Park incorporated in National Park in 2011. To do so, seventy-five plots($100m^2$) were set up and surveyed. The surveyed plots were divided into six groups according to the analysis of classification by TWINSPAN; (I) Quercus acutissima community, (II) Q. serrata-Carpinus tschonoskii var. tschonoskii community, (III) Pinus densiflora-Q. mongolica community, (IV) Q. variabilis community, (V) P. rigida-Q. variabilis-P. densiflora community, (VI) Chamaecyparis obtusa community. The results of vegetation structure analysis were. I, IICommunity, were expected that the deciduous oak trees with deciduous oak trees or Carpinus tschonoskii var. tschonoskii competing with oak trees would flourish in a deciduous broad-leaved forest. III, VCommunity, were expected that the P. densiflora and P. rigida competing with oak trees would flourish in a deciduous broad-leaved forest. IVCommunity, have expanded the influence of Q. variabilis, but understory will be developed next ecological succession by a high percentage of Machilus thunbergii in frequency of warm-temperate trees. VI Community, Chamaecyparis obtusa community were expected continue. This Chamaecyparis obtusa community is picked thinning Chamaecyparis obtusa as moving purpose of National Park, it will be inducement a plant vegetation succession to the natural forest. Frequency of warm-temperate trees in the Paryeongsan Zone of warm temperate climate zone was a total 9 species, Machilus thunbergii, Eurya japonica, Elaeagnus macrophylla, etc.

  • 지구의 온난화 특히, 도심지의 동절기 기온상승 등으로 난.온대 수종들의 식재 북방한계가 올라가고 있으므로 이제는 중부권지역에서도 남부수종의 활용이 가능하다고 본다. 따라서 본인은 오래전부터 서울경기지역 조경관련 지인들에게 몇몇 남부수종의 식재를 권유해 오고 있으며 중부권에 남부수종을 식재하기 위해서는 기술적인 연구와 검토가 사전에 필요하고 세심하고 철두철미한 준비가 뒷받침 되어야 하므로 지금까지의 경험상을 토대로 남부수종에 관한 소개와 몇 가지 참고사항을 전하고자 한다.
