  • With the emergence and development of ecological engineering in China, and also the research and demonstration of Chinese Ecological Agriculture (CEA), in recent 10 years many types of ecological engineering have been appeared in Southern China, they could be classified into 4 typical patterns. These typical patterns are; 1. Ecological Building (EB), such as ecological public toilet, ecological garden, ecological integrated building, farmers' ecological household, the combine of ecological building and CEA; 2. Ecological Engineering in Paddy Field (EEPF), like rice-fish system, water caltrop-wild ricestem-fish system, mulberry-silkworm-pig-fish system; 3. Ecological Engineering of Agroforestry Systems (EEAF), as tea-food crops intercropping system, rubber-tea-chicken system, bamboo-chicken system, fruit tree-chicken system, metasequoia-fish-duck system; 4. Ecological Engineering Linked with Biogas (EELB), such as animal (pig)-biogas-fish system, animal (pig)-biogas-fruit tree system, animal-biogas-food crops system. Some case studies were presented in the paper. It is showed that these typical patterns have better ecological, social and economic benefits, now they are deeply been extending in southern China.

  • We implemented ecological linkage assessment, through the connection components of the urban forests, rivers and parks, for the ecological connection of the urban parks which are standing out as the core of the urban green networks, so as to suggest basic data to compare, evaluate and improve urban green networks, as a basic study for the evaluation of the ecological connectabilities between the cities. For the ecological linkage assessment, we analyzed to see if the urban parks of Goyang, Ansan and Yongin, which are the subject cities, are actually ecologically connected with forests and rivers, using distance and roads, which are physical connection elements, in consideration of the mobility of the wild animals, and greening ratios and impervious pavement ratios, which are ecological connectabilities in consideration of the ecological values. The overall result of the ecological linkage assessment the physical connection elements and the ecological connection elements shows that the ecological green network ratio through direct connection states is 36.62% in Goyang, 42.55% in Ansan and 64.00% in Yongin, respectively, giving the ecological connectability ratio of less than half, with the average urban ecological green network ration of 47.72%. The comparison result of the ecological connectabilities between the object cities employing the connection elements indicates that when you set up green networks, you should consider together the physical connection elements, such as the roads, which will lower the ecological connectabilities - rather than do it simply based on areas and distances - while the ecological connection elements with the forests and the streams should be reinforced, so that the ecological connectabilities of the urban parks may be enhanced.

  • The most necessary thing for education now, is an ecological approach to look at and be conscious of the uncertainty of nature and the structural contradiction of society. In brief, we need to make a judgment on what standard and value are required for a forming righteous relation between nature and human being, and include it in the notion of citizenship. Based on this point of view, this study extracted moral virtues, skills and agreement mechanisms of new citizenship from ecologism, environmental justice and the ecological community, and systematized them. From ecologism and environmental justice, virtues that are inner values to lead ecological citizen's act and skills as capabilities required for correcting environmental injustice, were derived. Then, workings of citizens in a community and directions of each society and education were considered from the ecological community as an utopia where ecological citizens ultimately aim for. As the result, the ecological sensitivity, freedom, creativity, a sense of justice, a sense of responsibility, caring were found to be moral virtues that ecological citizens have to have. Next, ecological thinking skills like systemic thinking, quantitative thinking and empathetic thinking, and principles of deliberation and perturbation as mechanisms to improve communication skill and environmental injustice which have been considered importantly as components of democratic citizenship, were selected as skills of ecological citizens.

  • The purpose of this study is to suggest an environmentally friendly energy system of ecological architecture, with the reference to foreign cases, judge feasibility of it. The ecological architecture is very similar to the natural ecosystem. There is growing international scientific consensus that human activities are having a discernible effect on the global climate. Therefore, with a precise understanding of the concept of ecological approach and concrete perception of the necessity it, an establishment of planning which recognizes the ecological architecture as a organism a same time, ensures diversity, stability and cycling stemmed from the ecosystem to various activities through a ecological structure shall bring the introduction of substantial ecological architecture into domestic realm. As a result, in this Age of industrial science, We are proposing useful materials and suggestion regarding the ecological architecture planning of korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

  • The purpose of this study is to develop design model of ecological park as stormwater storage facilities. The results are as follows : First, the design model of ecological park as stormwater storage facilities consider ecological and landscape characteristics such as high efficiency of land use, function as disaster prevention, ecological water purification, formation of habitat for flora and fauna. Second, this study demonstrates two types of plane structure and eight types of designed section. They can be combined and designed depending on conditions of each site. The facilities of stormwater storage conduct disaster prevention system and ecological park. Retention pond in stormwater storage facilities for ecological park also should be made for ecological restoration in the site. Third, the ecological park provide the basis for ecological network from in-site to out-site. Therefore its conservation and restoration plan consider the ecosystems of the site. Fourth, the most important factor for maintenance and management for retention pond is keeping water quality. Sustainable Structured wetland Biotop system is suggested for ecological water purification system in the retention pond which is one of the constructed wetland system using multi-celled aquatic plant and pond. This system can also provide habitat for animals and plants, water friendly park for men, and beautiful landscape.

  • This study was performed to investigate the awareness of an ecological city and its related variables and the willingness to move to an ecological city and its related variables. Data were collected through a questionnaire survey given to 491 residents in Mokpo, Kwangju and Muan in Chollanam Province. Awareness of the ecotogical city was medium level, half of the respondents were not aware of the ecological city. Multiple regression analysis was conducted to estimate the effects of the variables on the awareness of the ecological city. The most significant variable was environmental knowledge. Next, experience in environmental education and homeownership effected on the awareness of the ecological city. Those who knew about environmental pollution and environmental disruption had a self-reported higher degree of awareness of the ecological city. Those who had experience in environmental education as well as those who lived in their own house were more aware of the ecological city. Other variables were not statistically significant. Half of the respondents were willing to move to the ecological city. Seven variables were related with willingness to move to the ecological city. Those who knew about the environmental pollution and environmental disruption preferred to move to the ecological city. Those who lived in multi-housing had more of a willingness to move to the ecological city. People with a higher education as well as the younger group preferred to move to the ecological city. Those who were more aware of the ecological city and had more ecological-oriented values had more willingness to move to the ecological city. Salaried men and professionals were more willing to move to the ecological city than non-employed people. Among those variables environmental knowledge was the only influential variables on willingness to move to the city.

  • Restoration to improve the ecological quality of Mt. Nam was explored in a viewpoint of restoration in both landscape and ecosystem levels. A restoration plan in landscape level was based on the result on the land-use pattern in Mt. Nam including its surrounding area and that in ecosystem level on the ecological quality of each landscape element. A plant to construct the green network, which extending from Mt. Nam to the Han river through the Yongsan family park and through the Eungbong urban park was prepared as a restoration project in landscape level to improve the ecological quality of Mt. Nam as an ecological park. On the other hand, a plan for restoration and creation of biotop as a restoration project in ecosystem level was also prepared to improve the ecological quality of each green area consisting green network. Green areas composing green network include keystone green area (Mt. Nam), green stations (Yongsan family park, Eungbong urban park, and the han river citizen's park), and green pathway (or ecological corridor) connecting those green areas.

  • This Study aims to find out the planning aspects and detailed techniques in terms of concept of the Ecological Industrial Parks. It consists of the three parts : Firstly, according to theoretical review, this study gives a definition of the concept of ecological industrial parks. Secondly, it institutes planning aspects of ecological industrial parks based on the main concept. Thirdly, 8 case studies show us analysis of detailed techniques used each planning aspects. Ecological industrial parks mean industrial systems which make energy and substance circulated in order to reduce environmental pollutions inside and outside of park like natural ecosystem. To actualize ecological industrial parks, we have to adopt 3 planning aspects which are energy and substance recycling system, environmentally-friendly site planning based on ecology concept, constructing of ecological production and management. In case study, detailed techniques from each planning aspects are shown in table 8. As a result of case study, detailed techniques about planning of energy and substance recycling system is accommodated most. On the other hand, environmentally-friendly site planning techniques based on ecological concept is used passively. And detailed techniques about constructing of ecological production and management are very various as each cases. Finally, in terms of analysis, this study shows us appliable planning when we develop domestic Ecological industrial parks.
