This study aims to present an evaluation scheme to improve the problems in tree shapes and tree growth which were identified through shape and growth assessments of landscape trees currently planted in Haedoji Park, Songdo, Incheon Metropolitan City after plant structure status and propriety review for funtion of space and concept of planting. Suitability the planting concept was evaluated according to function of space. The result indicated that the shade planting areas accounted for 29.5% of the the shade spaces area. 58.7%, respectively planting areas of visual landscape. And 11.8%, respectively planting areas of buffer. Because the planting areas was lacked according to the park established spatial configuration of central facilities and the result of plant young trees. Plant structure status required consideration with plant structure, density, size, growth status for improve planting function. The tree assessment was performed on a total of 28 species and 600 trees of which 22 species and 209 trees were planted in the buffer zone, 8 species and 71 trees in the shade zone, 16 species and 266 trees in the visual landscape zone, and 4 species and 54 trees in the ecological landscape zone. The trees were divided into grades based on their assessment score and were statistically grouped by the functional zone in where they are planted and by tree species to verify their significance. The tree shape assessment was an average of 56.6 points and the tree growth assessment was an average of 76.0 points. Using the results of the tree assessments, the tree standards for each functional space were identified and a concept of optimum planting and cultivating was applied. When applying the shape assessment results by zone to the concept of planting, since trees for buffering require high functionality they received E's, the lowest grade; as trees for ecological landscaping require diverseness and naturalness, they received D's; since trees for shading require utilization, they received C's as trees with branching at the main stems were considered; and since trees for visual landscaping required aesthetical value, they received A's and B's. When applying the growth assessment results by zone to the concept of planting, based on planting foundations of favorable and poor, for buffering, visual landscaping, and ecological landscaping, trees from grades A to E could be planted, and for shading, trees from grades A to C could be planted. For a cultivation plan that could improve the growth of the trees, we proposed that the topography of the land be selected considering the tree's characteristics and that a method of pot seeding be used. Also, to improve the shape of the trees, we proposed that poles be used to improve the growth of vertically-straight stems, an appropriate planting density be applied for reasonable branch growth, manage tree shape to maintain good crowning, and better manage fertilization to maintain a reasonable crown density.

To investigate the plant community structure in Pinus densiflora forests of Odaesan National Park, fourty plots(each size was 100m$^{2}$) were set up in Sogumgang and Woljongsa area. The classification by the TWINSPAN and DCA ordination techniques were applied to the survey area. Pinus densiflora forests were divided into five community types, which were Betula schmidtii-Acer pseudosieboldianum-Styrax obassia, Quercus variabilis-S. obassia, Q. serrata-Q. vareabilis, Q. mongolica, Abies holo[hylla. The successional trend of Pinus densiflora forests was seem to be seral stage from Pinus densiflora to Quercus spp.. And Abies holophylla was competition species with Pinus densiflora in Woljongsa area. So, management of Pinus densiflora forests requires to conserve for the diversity of mountain landscape resource and gene science.

The aim of this study is how to understand of structural and elemental landscape image in suburban village. Nowadays, it is well known fact that suburban villages are most likely to be invaded by urbanization. Therefore, the research is focused on how the image of suburb has been changed, what patterns have been created in residential area, what are the different outcomes from different distance, and what are the changes in types of buildings, at particular village called Doojeong in Pyeongtaek city. When collecting supplemental information, elders in village have been participated in comparison of traditional and foreign. The village shows significant characteristics of such phenomenon. According to the research, there are three results. First, ironically, the structural patterns of the village is concentric as seen on urban garden, yet they do not have central function. Second, traditional homes are transformed into functional shape. The most popular roof design that takes 65 percent of whole is modernized flat roof shape. Hanok (Korean traditional house) style is disappearing. Third, due to the massive barn buildings and their monochrome, the beauty of community and architectural harmony are buried.

Modern railway construction by Japanese had a great influence on the urbanization, transformation of urban structure and landscape during the Japanese imperialism and compressive increasing period in Iri(Iksan). This paper aims to find out the effect of railway on the modern urban structure and urban landscape in Iri(Iksan). Railways in Iri, Honam railway, Kunsan railway, Jeonla railway have been constructed progressively during 1911 and 1915 with Iri and old Iri(east-Iri) station. From the analysis of land registration maps and street plans, old photographies and historical records, some significant features underling railway construction can be followed in view of modern urbanization process in Iri. Firstly railways cut off the possibility of developing urban structure based on traditional spatial structure of Iksan. Secondly railways made dual spatial structure in Iri. Japanese and Korean life zone were divided into separate district around urbanization area and market place. Thirdly traditional space cognition system based on four cardinal directions were changed to front and rear space of railway station. Fourthly railways and stations caused neo-baroque spatial order and imperialistic urban landscape of Iri with axis, vista and gridiron plan. Fifthly break points and fringe belts garbling modern urbanization process are created. Sixthly modern cultural and consumptive urban spaces were taken their seats in relation with daily urban life.

하천 내 설치하는 수제는 제방보호 및 유로변경의 목적으로 하천내 시공되는 구조물 중의 하나로서 하천복원과정에 있어 필수불가결한 구조물 중의 하나로 인식되고 있다. 수제는 대개 하나 이상의 일련의 군집형태로 수로 자체의 특성을 고려하여 설치가 되고 있다. 그러나 이러한 수제의 무분별한 설치는 주변 경관을 저해하는 요소로 나타날 수 있을 뿐만 아니라 시공에 따른 비용에 적지 않은 부담을 야기 시키기 충분하다. 그러나 적절한 간격 조절을 통해 생태, 호안보호, 경관 등의 수제의 기능을 만족한다면 이보다 더 효율적인 것을 없을 것이다. 따라서 본 연구에서는 수제간격에 따른 하상변동 실험을 통해 효율적인 배치간격을 제시할 목적으로 수행되었다. 실험은 폭 1.2m, 길이 50m, 높이 1.5m 인 직선수로에서 수로폭의 15%길이를 갖는 연직수제를 2개를 대상으로 각각 수제길이의 2~8배의 간격 조절을 통해 하상변동실험을 수행 하였다. 실험용입자는 중간입경($d_{50}$)이 0.15mm 인 모래를 사용하였으며 6시간 동안 통수하였다. 실험결과 유수에 의해 첫 번째 설치된 수제에서 지배적으로 많은 영향을 받게 되면서 후면부에 설치된 수제는 비교적 영향을 덜 받고 있었다. 그러나 그 영향권을 점차 벗어나게 되면서 수제 간격이 4배 이상일 경우 후면부 수제에서도 세굴이 발생하고 있음을 확인할 수 있었다. 이러한 자료는 추후 수제설치에 따른 효율적인 배치 간격 결정에 중요한 자료로 이용될 수 있을 것이다. 그러나 수제들이 시공되는 대다수의 하천들은 어느 정도의 만곡도를 갖고 있기 때문에 이를 간과해서는 않될 것으로 판단된다.
