This study was conducted to investigate the plant community and to propose ecological planning methods for urban environmental forest on Gaepo neighborhood park, Gangnamgu in Seoul. Thirty-six plots that the size of each plot was 10$\times$10m(100\ulcorner) were set up and the vegetation analysis was carried out. Field survey was executed Apirl, 1994. The actual vegetation was consisted of Poplulus$\times$albaglandulosa community(73.03%), Robinia pseudoacacia community(8.30%) P. $\times$ albaglandulosa-R.pseudoacacia community(1.81%) and environmental forest (15.22%) in the survey site. According to mean importance values of each plot, survey area were divided into ten forest communities. As for the analysis of plant community structure which was classified into ten forest communities, the importance values, ecological diversity, number of species, number of individuals, basal area and crown coverage of urban environmental forest were relatively lower than those of the native community. In urban environmental forest of Gaepo neighborhood park, it showed problems for the planting method. So urban environmental forest should be constructed considering ecological characteristics based on above results.

식물종 다양성이 높은 하천변 복원을 위해 8개 하천 13지점에서 자연하천변 식물군락의 이질성을 ${\beta}$-diversity로 조사하였다. 그 결과, 하천에서 내륙으로 들어감에 따른 이질성의 평균값은 0.32이었다(0.23~0.37범위). 이 값은 식물군락의 종 구성이 6번 완전히 바뀌는 community turnover를 나타낸다. ${\beta}$-diversity는 섬진강, 한강, 낙동강, 금강 수계 간에 차이가 없었고, 각 수계 안에서 하천 유역은 하류(0.23)보다 상류(0.36)에서 더 높았다(p level<0.05). 환경요인과의 관계를 알아보기 위해 다중회귀분석을 실시한 결과 ${\beta}$-diversity는 경사도에서 유의성이 나타났다. Belt-transect를 통해 나타난 종들과 ${\beta}$-diversity 값을 통해 하천변의 우점종 모식도를 그려보면 상류의 종조성은 6번 바뀌고, 하류의 종조성은 약 5번 바뀌었다. 본 연구 결과를 통해 하천 계획에 실질적으로 활용할 수 있는 식재 수종과 식재 패턴의 기초를 제시하였으며, 하천변 식물군락의 종 다양성을 높이기 위해서는 경사도를 높이는 것이 가장 중요하다.

본 연구에서는 식생 복원 유형별 토양동물의 변화를 알아보기 위해 비오톱이식공법, 산림표토포설, 소경목군락식재, 다층구조군락식재를 적용한 조사구와 이를 비교할 대조구를 선정하였다. 토양동물의 변화를 통한 토양동물자연도 분석 결과, 대조구는 환경에 민감한 동물군과 둔감한 동물군이 골고루 출현하고 있어 토양동물자연도가 높게 확인되었다. 식재를 통해 복원된 조사구의 경우, 비오톱이식공법의 토양동물자연도가 대조구와 유사한 수준까지 도달해 있었으며, 이보다 낮은 수준이긴 하나 소경목군락식재, 다층구조군락식재지역의 토양동물 또한 점진적으로 회복되고 있었다. 가장 낮은 토양동물자연도를 보인 조사구는 산림표토포설지역으로 확인되었다. 이를 통해 비오톱이식공법이 식재를 통해 복원된 조사구가 다른 조사구에 비해 토양동물의 회복이 좀 더 빨리 이루어지고 있음을 파악할 수 있었다. 이는 산림 내부의 숲을 그대로 굴취한 후 이식하는 것으로 표토와 심토의 일부분이 함께 옮겨지기 때문으로 판단된다.

Regional development and community design has become very important these days. Especially in Hyogo Prefecture after the Great Hanshin Awaji Earthquake, voluntary works have become more popular. With citizen participation, environmental circumstances change a lot. It is becoming very difficult for municipal governments alone to achieve every desirable project. NPOs made of professional members in the Hanshin area have conducted notable activities after the earthquake. At the same time it is necessary also to educate citizens for community design with greenery. These people will support their town design along with professionals. Awaji Landscape and Horticulture Planning Academy provides an excellent educational program, an introduction and examination of which should be valuable. The main concept of the education program is to foster the growth of local community design leaders. Students appreciated the programs very much even if initially they expected a more practical program about planting than programs that teach community design. Many people are active in their own towns to create better environments and communities. The network system "Alpha Green-Net" is functional to support graduates of the course. In the future these educational programs for citizens will becomes very important. Other cities are starting to have their own progrms, but they are still very short term. "Alpha Green-Net" is in the process of growing. Many members are very keen to develop their own abilities. In the future these NPOs should become independent. To help these NPOs become independent and active the educational programs should consider and teach about how to do this more in the future.

In order to make plan for landscape construction by ecological methods in Yukong R & D Complex site, environmental factors and structure of plant community were investigated and analyzed around Yukong R & D Complex site of Daeduk. The result of this study were as follows: 1. In the result by the classification of TWINSPAN and ordination (DCA) techniques for analysing of plant community structure, thirty plant community structure, thirty plots were divided into four groups according to soil moisture and succession trends were seem to be from the development of subsidiary vegetation through Pinus densiflora, Quercus spp., Robinia psudoacasia community to Q. acutissima community. So this result was proposed to validity of vegetation introduction for planning of ecological landscape construction in studied site. 2. On the analysis of environmental factors by ordination techeniques, the plant community were divided by soil moisture. Soilcondition will be fertilized by introduction of broad-leaved tree and the development of succession trends from the present state of plant community to Q. acutissima community. 3. The problems of horiticultural places happened to studied site, so horiticultural places for ecological landscape construction was proposed planting techniques that were considered to soil suitability, economical efficiency, native species and wildlife. 4. If we attempt to ecological landscape designs on natural systems and use natural processes to achieve desired end-points, we are more likely to produce self-sustaining solutions.

The purpose of this study is to figure out the structural characteristics of urban plant community and suggest restoration model of Quercus mongolica in the case of Korean national Capital Region. The investigation areas were selected from urban area of Mt. Nam at Chung-Gu, suburban areas of Mt. Bong at Eunpyoung-GU, Mt. Sungju at Buchon City and non-urban areas of Mt. Suri at Kunpu City and Mt. Chonma t namyangju-City. After the main study field had been classified into the evaluation of the ecological characteristics and the modeling of the vegetation. We analyzed to evaluate the ecological characteristics of the forest structure -- successional stage, naturalness, multi-layer structure of the forest and species diversity, and the plant community structures. We have proposed vegetation restoration model based on the selection of proper plants, the number of individuals, diameter short area of breast height, the shortest distance between plants in non-urban area. As for successional stage, It was judged that the ecological succession may not be followed like the present stage of the surveyed areas in urban, suburban and non-ruban areas. As for the retention of naturalness and multi-layer structures of vegetation, In Quercus mongolica community, Robinia pseudo-acacia and Ailanthus altissima occurred in each layers at Mt. Nam, Mt. Bong and Mt. Sungju, and Eupatorium rugosum occurred in herbaceous layer at Mt. Nam. Consequently, the ecological restoration plan following the structure of the vegetation in Mt. Chonma seemed to be advisable in Q. mongolica community, there were less number of species and individuals in urban areas than those of non-urban areas. Planting of trees following the simulated native plant community of non-urban areas seemed to be required to promote the plants in urban areas. Considering the number of individuals up to three layers in each 400$m^2$ area, it was composed of twenty nine in canopy layer, forth nine in understory layer, 367 in shrub layer and 33.7% herbaceous ground cover in the Q.mongolica community. The suggested restoration model in this study is nan applicable model for the introduction in the cities, and this study shows that continuous experiments and field investigation on this model should be performed in the future.

Urban problems raised by the concentration of population in urban areas have caused residents to migrate to other regions while causing other problems such as deteriorated infrastructure, traffic and environmental pollution problems in existing urban areas. As an alternative to improve this phenomenon, urban regeneration has emerged, and under the assumption that creating community vegetable gardens is effective in revitalizing cities considering their physical, social and cultural environment, frequency and descriptive analyses were conducted on the vegetable gardens in Jungnosong-dong, Wansan-gu, Jeonju-si, Jeollabuk-do, Korea to examine differences in the components of the surrounding environment and the settlement, and community spirit of the two groups comprised of 30 and 35 persons who did not and did participate in gardening respectively. Regression analysis were conducted to determine whether there were changes in community spirit after participating in gardening. As a component of the surrounding environment, gardening and fence management were found to be important for both the groups, and they seemed to have high satisfaction with their residence because they wanted to continue to live in their neighborhood. Overall, the satisfaction evaluation results showed that those who participated in gardening showed a higher satisfaction level than those who did not. Based on the changes in community spirit after participating in the activity, it was found that there was a high level of perception in all the components, indicating that the gardening had a positive effect on the cultivation of community spirit. As such, the spaces called vegetable gardens are not only for doing physical activities but also as shared conversation topics, and through the activities in the gardens, changes in the awareness of local residents can be brought about through the formation of social networks and natural communication between neighbors. It can be concluded that they encourage residents to actively participate in improving the urban environment through activities such as planting.

Root-knot nematode disease is a widespread and catastrophic disease of tobacco. However, little is known about the relationship between rhizosphere bacterial community and root-knot nematode disease. This study used 16S rRNA gene sequencing and PICRUSt to assess bacterial community structure and function changes in rhizosphere soil from Meloidogyne incognita-infected tobacco plants. We studied the rhizosphere bacterial community structure of M. incognita-infected and uninfected tobacco plants through a paired comparison design in two regions of tobacco planting area, Yuxi and Jiuxiang of Yunnan Province, southwest China. According to the findings, M. incognita infection can alter the bacterial population in the soil. Uninfested soil has more operational taxonomic unit numbers and richness than infested soil. Principal Coordinate Analysis revealed clear separations between bacterial communities from infested and uninfested soil, indicating that different infection conditions resulted in significantly different bacterial community structures in soils. Firmicutes was prevalent in infested soil, but Chloroflexi and Acidobacteria were prevalent in uninfested soil. Sphingomonas, Streptomyces, and Bradyrhizobium were the dominant bacteria genera, and their abundance were higher in infested soil. By PICRUSt analysis, some metabolism-related functions and signal transduction functions of the rhizosphere bacterial community in the M. incognita infection-tobacco plants had a higher relative abundance than those uninfected. As a result, rhizosphere soils from tobacco plants infected with M. incognita showed considerable bacterial community structure and function alterations.

This study investigated the composition and distribution of the soil microarthropods community in plantations of the Korean pine(Pinus Koraiensis SIEB. et ZUCC, the sudong area, Namyangju-gun, Korea) , which had been planted in different years. The soil samples intended to collect soil animals were taken monthly from June 1988 to July 1989. The composition of soil microarthropods community included Arachnida, Chilopoda, Insecta, Collembola, Diplopoda, Crustacea, and Symphyla. The Acarina were composed of 82.4% of Cryptostigmata, 8.0% of Mesostigmata, 7.9% of nymphs, and 1.7% of others. The Insecta included six orders including Hymenoptera(65.8%) and Diptera(13.9%). Population densities increased from when the plantations were first established until the planting were 25 years old, after which they declined. Population densities of the soil microarthropods were highest in July and lowest in January. The Collembola/Acarina ratio is 0.16 overall, and was highest in January and lowest in August.
