  • 한국에서의 $C_3$$C_4$CAM 식물의 지리적 분포를 알아보았다. 한국 전체에서 258 군데의 지역에서 모든 초본식물들의 목록을 작성하고 각 식물들의 중요값을 통해 우점종을 결정하였으며 이들 식물의 분류에는 크란츠 해부구조의 존재 관찰을 비롯한 여러가지 방법들을 사용하였다. 이 연구의 결과에 따르면 우리나라의 $C_4$형 초본식물은 총 7개과 92종이었으며 $C_4$식물의 대부분은 화본과 식물이었다. 대한민국에서의 $C_3$$C_4$형 초본식물의 분포는 초본식물의 서식지와 관련되어 나타났다. 야외 및 해변의 건조지역에서는 $C_4$형 초본과 조건적 CAM 식물이 주로 서식하고 있는 반면, 습윤 지역에서는 주로 $C_3$형 초본식물이 많이 나타났다. 조사된 총 258개 지역 중에서 잔디가 우점종인 지역은 6개 지역이었다.

  • The purpose of this reserch is to investigate the flora of Dumi Island. This island locates at $128^{\circ}$ 13' E. longitude and $34^{\circ}$ 41' N. latitude. As a result of our investigation, the distribution of plants on Dumi Island could be summarized as follows. The vascular plants through this investigation were 66 families, 121 genera, 127 species, 16 varieties, 2 forma, and 145 kinds. From 1945 to 1960, most Pinus densiflora and Quercus mongolica were cut and sent as fuel to the cities of Masan, Chungmu and Samchunpo. After these deforestation years, there was a change of policy in the area and then wood was substituted by coal blacks as fuel and along with this occurs reforestation. Because of the reforestation by the present administration and natural means of suctrees, Castamopsis cuspidata var. thunbergii, Camellia japonica and Machilus japonica; they were found to exist near Sheonangdang in the northern region at Hakli and at Kuchun in the south. In the central part of the island at Mt. Chunhwang there are slopes of 20-30 degrees which are cultivated by the islanders this mountain which can be cultivated and 65% or 830 islanders are farming this land. Although this 125.4 hectors is not a large portion, this mountain with its variety of growth at different elevations, seems to be very fertile causing thick growth at any level.

  • To evaluate the natural environmental conditions of the local areas, the methods using the plant species and plant community are discussed here, Based on Ohba's(1979), Nakanish's(1980a: 1980b), Okuda and Nakamura's(1989), and Haber et al.'s systems(1991), as the evalution-items, 9 in plant species level and 16 in plant community level are proposed. The evalution-items are classified as 3 criteria in plant species level and 4 criteria in plnat community level. The evalution method could be used to promote the spacial planning and to alleviate other administrative problems. Also it could be applied to decide conservation level of plant species and plant community.

  • Feeding plants of rice water weevil(RWW) adult and larvae were observed. Thirteen families including 104 species were found as host plants of RWW adult, and 74 species of them were newly identified as its host. Thmedia triandra var. japonica, Luzula capitata, Agropyron tsukushiense var. ransiens, and Zoysiama crostachya were most favorable hosts of adult RWW. Host plants for larvae were 9 species of weeds including Cperus nipponicus, Eleccharis kuroguwa, Sagittaria trifolia, and Claviceps purpurea in the rice paddy fields.

  • The vascular flora of Mt. Deokhang (a.s.l. 1072.5m, $37^{\circ}17^{\prime}{\sim}37^{\circ}20^{\prime}N$, $128^{\circ}09^{\prime}{\sim}129^{\circ}03^{\prime}E$), one of the limestone areas in Korea and is located between Samcheok-si and Taebaek-si, Gangwon-do, is surveyed from 10 Oct. 2003 to 4 Oct. 2005. The characteristics of the flora from the phytogeographical point of view is also discussed. The number of the vascular plant taxa identified in this study is 590 in total which belongs to 90 families, 337 genera, 537 species, 4 subspecies, 46 varieties and 3 forms. Of them, 30 taxa are endemic to Korea, 4 taxa are legally protected ones, and 17 taxa are generally regarded as rare and endangered species in Korea. Naturalized plants are 19 taxa. The phytogeographical importance and the conservation strategy of the flora of Mt. Deokhang focusing on either rare, endemic or phytogeographically important species are discussed.

  • The floristic target species (FTS) has been widely used as a important tool for environmental assessment in Korea. Here the floristic district is a key criterion for the selection and evaluation of FTS. The aim of this study is to clarify the intellectual meaning of the floristic district i.e. a sort of phytogeographical subunit. We reviewed 7 main literatures related to the floristic district. Nakai's 1919 Ulleungdo flora survey report was first to mention a region and/or province in terms of general geographical divisions. In 1977, the floristic district map of the Korea vascular plants was first described by Oh. In 1978, Lee & Yim proposed a new floristic district map dividing the central and southern regions, and the district boundaries have been adjusted by many other researchers. In the end, the floristic district map modified slightly from Lee & Yim's map was nationally recognized in 2018. However, the boundaries of floristic districts were inconsistent, both in their setting and adjustment, as well as the indicator species of the district. No basis for this inconsistency could be confirmed. We concluded that all district maps depend on arbitrary lines drawn a priori, and finally proposed the following two ecological strategies to ensure the effectiveness and practicality of the FTS as a scientific means for environmental impact assessment and national flora evaluation: (i) designing to achieve the flora list and the floristic district based on nativeness of plant distribution, (ii) constructing a habitat-based floral monitoring system.

  • This study was performed to investigate species diversity of understory in Mt. Biryong. The quadrat size was installed based on the result of analysis of Species-Area Curve. The vascular plants were enlisted 107 taxa: 47 families, 80 genera, 91 species, 11 varieties, 2 subspecies, and 3 forms. The three taxa such as Carex okamotoi, Philadelphus schrenkii var. schrenkii, and Weigela subsessilis were enlisted from the surveyed sites as the Korean endemic plants. Due to the list from the Korea Forestry Administration, Rhododendron micranthum was enlisted as the rare plant. The growth from was categorized followed by forbs, shrubs and trees, respectively.
