This study was conducted to examine the state of confusion about those azalea cultivars(hereinafter, Azalea Cultivars) that are used among practicians in landscaping businesses(designers, constructors, and producers). Which Azalea Cultivars would be delivered when they were ordered to producers using the names of Azalea Cultivars notified by the Public Procurement Service. In addition, the situations of azalea cultivar planting designs in the planting design drawings of three apartments completed recently and whether the Azalea Cultivars on the design drawings were the same as those Azalea Cultivars that were actually planted were examined. When Azalea Cultivars were ordered using the notified names, three Azalea Cultivars; Beni, Three, and Daewang were delivered for the name Yeongsanhong and two Azalea Cultivars; Zasanhong and Hancheol were delivered for the name Zasanhong. Yeongsanhong was perceived as a common name of Beni, Three, and Daewang by producers. Therefore, this caused confusion between producers and purchasers. In the case of Zasanhong, as the traits of Zasanhong are similar to those of the cultivar Hancheol, the producers or purchasers might have been unable to clearly distinguish between the cultivars and thus two cultivars might have been delivered without being distinguished from each other. The names of Azalea Cultivars used in planting design drawings were the names notified by the notifying agencies or comprehensive and unclear names such as azalea and Yeongsanhong. Completely different Azalea Cultivars from those written in planting design drawings were planted in actual construction sites in many cases. These situations should have occurred because designers did not write accurate cultivar names in planting design drawings and constructors could not accurately perceive the classification characteristics of individual Azalea Cultivars but planted those Azalea Cultivars with similar flowers colors or those that could be easily bought to fit the conditions of construction sites.

This study was carried out to analyze the problems on several steps of the establishment of the Nature Ecological Forest in Yeouido Park, Seoul, and also to suggest improved approaches on each step. For execution drawing, planting models and plans seemed to be uncertain, and the quantity and size of planting trees seemed to be impractical. For construction, the woody plants planted on the site were different in species and size from the planting plan. Ecological planting was somewhat limited because of the inappropriate soil properties. For management, replacement of the dead trees was not executed properly, and no management scheme was prepared after the replacement period. We suggested improved approaches for the establishment of ecological forests in urban areas as follows: for execution drawing, overstory, understory and herbaceous ground cover layers should be composed based on standard plant community structures. Trees that are available from tree markets should be specified in the planting plan. For construction, trees for planting need to be tagged to identify species and size. When tree species and size are changed, they should be checked to ensure that they are proper to the plant community model. Soil information should be collected to check that they fit the target plant community model. For management, the proper amount of trees needs to be specified in the planting plan by applying regular discount rates, especially for trees supplied from the government sector. The replacement period should be extended from two years to five years. The change of plant communities should be monitored during first five years after establishment.

As most landscape drawings tend to be recorded in electronic format, the need for layer standards is growing. While the categorization system of planting drawings has been progressing, landscape facility drawings are being delayed. So, the purpose of this study was to establish the categorization system of computerized landscape facility drawing documents. In the beginning of this study, it found that the layer categorization system of "The Standards of Construction CALS/EC computerized drawings v1. 1" and "The submit instructions of electronic design documents" are not suitable for the landscape facility drawings. 1,154 drawings drawn by 10 landscape architect offices were used to analyze the current layer categorization status. As a result, it found that "The Standards of Construction CALS/EC computerized drawings v1. 1" were not introduced in landscape facility drawings and 46% of layers were produced indefinitely. The new layer categorization system consisting of 15 facility items was drawn by applying the ISO construction information categorization system. The new layer categorization system is set on the basis of the legal code, landscape design standards, and design guidelines of public institutions. This new layer categorization system is expected to propagate at the landscape architect offices in the early.

This paper categorized the functions of and investigated the characteristics of planting in Pyeonghwa Park near the Seoul World Cup Stadium as a preliminary study for improving tree planting in the park. The functions of planting were deduced based on related theoretical studies and an analysis of the intention of design and environmental factors. The characteristics of planting were analyzed after drawing the distribution and stratification of dominant planting species and setting samples by function. The functions of planting were classified into natural landscape planting, buffer planting, and shade planting. For dominant planting species, pine trees and elm-like trees have been widely observed while various species in addition to pine trees in natural landscape planting areas have been introduced in terms of the function of planting. These trees that were randomly planted before the park was developed have been obstacles in the formation of natural landscapes. For buffer planting and topographical correction, tall trees were planted. However, it seems that comprehensive complementary measures should be taken on the under-story planting.

The main purpose of this study is to examine the use of plant species in ecological restoration projects. To this end, planting drawings from 58 sites that had completed the return of the ecosystem conservation cooperation fund for the past six years were collected and analyzed. The analysis used the construction completion and design drawings to determine the overall selection status and analyze frequency by classifying planted plants into wild and cultivated plants by nature, size, vegetation climate, and upland and wetland habitat. The investigation and analysis process found many cases of wrong plant names, so an analysis was also performed on the matter. In the 58 investigation sites, 282 plants were used for planting: 91 tree species, 69 shrub species, 11 vine species, and 111 herbal species. The most commonly used plant species was Spiraea prunifolia f. simpliciflora, followed by Sorbus alnifolia, Quercus acutissima, Zoysia japonica, Callicarpa dichotoma, and Weigela subsessilisin that order. The most commonly used tree species was Sorbus alnifolia,followed by Quercus acutissima, Zelkova serrata, Chionanthus retusus, and Cornus officinalis, in that order. The most commonly used shrub species was Spiraea prunifolia f. simpliciflora, followed by Weigela subsessilis, Callicarpa dichotoma, Rhododendron yedoense f. poukhanense. and Euonymus alatusin that order. The most commonly used herbal plant species was Zoysia japonica, followed by Dendranthema zawadskii var. latilobum, Aster koraiensis, Miscanthus sacchariflorus, and Pennisetum alopecuroidesin that order. In the analysis by vegetation climate, Spiraea prunifolia f. simpliciflora, Callicarpa dichotoma, and Sorbus alnifoliawere most used in that order in both the temperate central and the warm temperate forest zones, but the pattern does not properly reflect the climate characteristics. In the analysis by habitat, Miscanthus sacchariflorus and Lythrum salicariawere most used in the wetland. In particular, the ratio of wild plants to cultivated plants was 76% to 24%, indicating the ratio of selecting cultivated plants was high. The names of plants on the drawings were mostly common names that did not appear in the Korea National Arboretum or the National Species List of Korea. It is necessary to use proper plant names in the future. Regarding the use of planting plants for ecological restoration, it is necessary to adopt the approach of diversifying selected plants, selecting plants according to characteristics of climate zones, and lowering the specifications of plants used for ecological restoration. Moreover, it is important to fully understand the ecological characteristics of wetland plants and minimize the ratio of using cultivated plants to ensure the plant selection centered on wild plants.

경기도를 사례로 검토한 결과, 가로수관리의 공통업무는 현황도면관리, 식재방법, 대장 관리, 자료관리, 상세업무, 통계관리로 나타난다. 그러나 겸무가 많아 이러한 주 업무에 대한 투자시간이 짧고, 대부분 수작업의 관리대장을 이용하고 있어 대체로 체계적인 관리가 이루어지고 있지 않다. 또한 관리시스템이 갖춰진 고양시의 경우도, 시스템이 범용GIS 이전에 구축되어 국가설계안과의 조합이 불가능하며, 가로수업무가 도로의 일부분으로 취급되어 업무가 불명료하고, 투자비용에 비해 활용도가 크게 떨어지는 것으로 나타난다. 본 연구에서는 동두천시를 사례로 이러한 관리업무의 흐름과 문제를 더욱 구체적으로 밝혀, 국가범용GIS에 대응하는 가로수관리시스템 기본설계안을 제시했다. 이 설계안은 가로수관리상의 문제 및 현실여건을 고려하여. 1)가로수관리 담당자가 관리업무를 체계적으로 수행할 수 있도록 업무기능을 설계하고, 2)효율적인 가로수 관리를 위하여 대장을 조회/수정/저장 및 출력할 수 있을 뿐 아니라, 노선/수종별 가로수현황 및 환경상태파악을 할 수 있도록 가로수통계현황 기능과 공간검객 기능을 설계했다는데 특징이 있다.

The flora of the Chuwangsan National Park was surveyed. The field works was done for three times from February to October, 1994. The total number of vascular plants in this area were surveyed as 433 taxa ; 94 families, 260 genera, 365 species, 60 varieties, 2 subspecies, 5 formas, and 1 cultivars. The twenty seven taxa which were artificially planted could be found at the temple and abandoned cultivated areas. The population of Jeffersonia dubia Benth, one of the rare and endangered plants in Korea, were surveyed and mapped for an ecological monitorings in the future. Since this population is restrictly located in the vicinity of the mountain trails, the protection measures should be urgently needed in the future.

With the changing of social needs and paradigms, citizens are concerned about aesthetic and cultural community gardens from productive urban farms in Korea. It is still difficult, however, to cultivate a beautiful garden with a community to design, install and manage it. Therefore, this study analyzed the community garden design guidelines of other countries to derive the characteristics and implications. The research method analyzed six guidelines for community garden design in the UK, Canada, the USA, Australia and Japan. As a result of the study, most community garden design guidelines are opened freely via on-line service. The guidelines are composed with chronological processes such as intro, site selection, design, construction and maintenance. The introduction section treats definition, purpose, meaning, efficiency and success factors for community gardens. Site selection emphasizes site conditions (soil, light, shadow, water, etc.), landholding and insurance. The design section, however, lacks adequate drawings and case images. These guidelines offer little explanation with few illustrations and sentences. Construction sections explain about plantings, facilities, expense and details. The maintenance guidelines of community gardens contain how to control members, funding, harvesting, pests and plants. In addition, some guidelines include vandalism, organic cultivation methods, recording and advertisement. Lastly, the appendix contains a variety of checklists, administrative documents, guidelines, drawings, and contacts. This study will help understand the trends and characteristics of overseas community gardens design guidelines so as to also supply directions for guidelines to be introduced in Korea.

Design of a vegetation type sound barrier was presented as a noise barrier on the boundary of neighborhood facilities including schools, and apartments. The suggested noise barrier is made of unit blocks that are to be formed by stacking over the wall structure containing the plant and soils in the blocks. The advantage of the vegetation noise barrier is to acquire not only sound absorptive effects of plants and soils, but also sound diffusive effect caused by the irregular surface of the barrier which could eventually mitigate the noise. First, the optimum size of the units to obtain the highest noise reduction was investigated using 1/10 scaled model experiment, and sound attenuation experiments were carried out using a 1/2 mock-up model which is 2 m high and 5 m long. Total 1,137 unit blocks were made of synthetic woods with the size of $10{\times}10{\times}9cm$. These unit blocks were installed on the both side of the 1/2 mock-up steel framed noise barrier. As a result, it was revealed that the block typed vegetation noise barrier has 7 dB higher insertion loss in comparison with the general plane noise barrier. Also, it was found that the appropriate size of unit blocks is $20{\times}20cm$ which has large effect of sound insertion loss.
