Natural disturbances and human development can cause habitat fragmentation. Plant and wildlife can become isolated, and habitat fragmentation and shrinkage have been recognized as a key issue facing the conservation of biological diversity. However, eco-corridors can alleviate the problem by providing linkages between isolated patches. The purpose of this study is to plan the eco-corridor for connecting urban forest via the urban stream with low cost and to restore the ecosystem. The results were as follows (1) Falco subbuteo, and Dryocopus martius inhabit in the study site. They are protected species designated by Korean Ministry of Environment. Thus the study site should be preserved as urban wildlife habitat species biodiversity (2) If the biodiversity of the study site is maintained properly, the eco-corridor can be constructed with low cost.

The urban rivers have unique hydraulic characteristics between natural rivers and artificial canals. These hydraulic characteristics determine the characteristics of urban rivers with small environmental capacity and fragile ecosystems. With the development and utilization of natural resources, the pollutants that have been produced enter the river through different channels, which seriously damages the urban river ecosystem. Therefore, how to restore contaminated water to a normal state and reproduce a natural, self-regulating ecosystem is one of the most concerned issues in recently. Eco-hydraulics is a cross-disciplinary subject of hydraulics biology and ecology. It is closely related to the protection of rivers, wetlands, and ecological self-repair. In this study, The basic principle of eco-hydraulics is concisely described and its approaches to protection and rehabilitation of river are introduced. The conception of establishing gardenesque eco-pond for urban use is suggested. The strategies including changing the hydrodynamic features of rivers, adjusting the breeds and species and constructing the gardenesque eco-pond for improving the exist ing urban rivers are proposed. It provides scientific information and guidance for the restoration of rivers and wetlands by studying the close relationship between river hydraulic characteristics, currents, and rivers and ecosystems.

Urban outdoor playground serves as the space to promote the physical, cognitive, social, creative, emotional and linguistic development of children and the education center to stimulate the imagination and curiosity of them. It is also the place to be used as a basic park for urban residents and the local community space for associating with people of various levels. However, this playground as a banal space did not function properly before now. In 21st century, urban playground requires change and its various changes have been attempted. In particular, there is a need for the change into eco-friendly playground to provide children's health and urban healthy environment. Therefore, it requires much effort to construct and vitalize the eco-friendly playground adequate for domestic circumstances in Korea. This study derived the preferred planning items among eco-friendly playground planning elements focused on the people to use it and provided the data for the construction of local friendly, eco-friendly outdoor playground. For this purpose, we visited the playground of the apartment house built in 10 years with more than 300 households and surveyed 200 adults and investigated the residents' utilization and satisfaction on the current playground and the recognition and preference for eco-friendly playground.

The purpose of this study is to define U-Eco City services and to analyze the possibility and easiness of application in urban space. The most significant meaning of this study is that these results could be used as the design and planning guidelines for integrated U-Eco City. This study progress as follows; First, U-Eco City concept and their services were defined and the spatial units of U-Eco City were distinguished through literature review. Second, U-Eco City spaces are classified into four levels such as building, street, facility and district. Finally, the application of U-Eco city services was analyzed together by the statistical technique of cross-tabulation. 35.7% of U-city services was serviced in urban district and 38.8% of Eco City services was applied to Building. U-City and/or Eco city services were adapted differently according to the urban spatial hierarchy. Those services should be applied in terms of the characteristics of urban space in designing and planning U-Eco City.

This study was carried out to create a master plan for an urban eco-forest, including concepts of forest restoration, forest management, and nature education. The concept of an urban eco-forest is different from the original eco-forest, which pursues the conservation of native species in their habitats, using the resources of special plants, etc. The study site was a hill (128m) managed as an urban natural park. Citizens have usually used the park for fitness purposes, as a place for outdoor exercise early mornings on weekdays and holidays. The result of a questionnaire survey showed that the users knew about the eco-forest, and they wanted to participate in the nature education programs. The flora and actual vegetation were weak about conservation of native species on the site. The framework of the plan consisted of development of the ecological forest and forest restoration, and allowed for recreation and the experience of nature, according to the concepts of the urban eco-forest. The landscape was divided into the experience zone of biodiversity, the experience zone of a valley ecosystem, the forest restoration zone, and the recreation and experience zone in nature. Based on this framework, detailed programs and theme areas were planned, as were forest restoration models and planting plans.

Background and objective: This study was conducted as part of research to promote garden diversity and seek sustainable garden management plans, as well as to determine the trends in understanding and use of companion plants as an eco-friendly farming method and provide the results as the basic data for sustainable urban agriculture. Methods: To determine the trends in garden activities, eco-friendly pest control, and use of companion plants, a survey was conducted on 230 urban residents participating in the Urban Agriculture Expert course. 223 copies of the questionnaire were collected excluding missing values, and IBM SPSS statistics Ver. 25 Program was used for frequency analysis, descriptive statistics, and regression analysis. Results: Most of the respondents were female (71.3%), homemakers (26.5%), were in their 50s (29.1%), and had 2 members in the family (27.8%). 164 respondents (73.5%) had experience in gardening, most of them once a week (31.7%) and for self-consumption (55.5%). Both men and women raised crops for safe food production (32.3%), and they most preferred the city garden type (39.9%). For the preparation of nourishment for eco-friendly garden management, most respondents (60.1%) purchased fertilizers from the market. For the reason why eco-friendly pest control is necessary, all respondents except 4 of them (98.2%) responded that it is necessary 'because it affects my health as I eat it (73.5%)', indicating that they still had a high level of interest in health. Only 43.9% of the respondents said that they had heard of companion plants, 89.2% responded that companion plants were effective in eco-friendly management, and 87.4% showed the will to participate in gardening using companion plants in the future. Finally, the regression analysis confirmed that the awareness of companion plants and satisfaction with gardening activities are key variables that increase the intention to participate in gardening activities in the future. Conclusion: Since plants require special care depending on the period and various diseases and insect pests occur, there must be continuous research on companion plants as an eco-friendly farming method. Moreover, by actively using companion plants in urban gardens with the utility value in not only eco-friendly pest control but also in helping plant growth, urban agriculture is expected to be continuously activated and promoted by increasing satisfaction in gardening activities with aesthetic landscaping and pest control.

With the launch of a new millenium of the 21st century ahead, one of tasks that need to be considered in urban ecological aspect is the understanding of impact of continuing urbanization on urban ecosystem, habitats, and various species of animals and plants. In addition, alternatives and measures to mitigate these impacts including environment restoration should be pursued. In this article, the following points will be reviewed; 1) the definition and significance of an eco-city and "ecological network", 2) the necessity of an eco-network as one of factors composing an eco-city, in the aspects of urban planning and urban ecology, 3) ways to build an urban ecological network and example of foreign countries, 4) as an example of a city in Korea, the present state and impending tasks of the ecological network of Seoul city, and 5) a brief conclusion and suggestion. By providing a basic tool called "an ecological network" for urban space planning, it attempts to contribute in promoting networking of cities (netropolis) and urban biodiversity. It is believed that how to create an ecological network in an artificially developed urban area is a pending issue we are faced with. Herein lies the necessity of natural environment restoration and creation based on the so-called the Third Ecology. Regarding the efforts to return the Nature to urban citizens, there is a need to view the development of a desirable urban ecological network as the starting point and finishing point of the effort. In this way, it is believed that the objectives of urban sustainability through netropolis development would also be achieved.
