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.

Purpose - The study on the consumption structure of urban residents can help us to understand demand law and to grasp the changing consumption trend of people. Consumption structure is an important indicator reflecting the people's living standard. It is of realistic significance to study urban consumption structure. Research data and methodology - This study is carried out with data connected with urban residents from Shandong Statistical Yearbook for the period 2000-2010 analyzing eight commodity groups. The almost ideal demand system (AIDS) is one of the important models related to consumption structure. Results - This paper shows that firstly gives a brief introduction to AIDS. Then it makes an empirical analysis on the urban residents' consumption structure in Shandong province, China on the basis of AIDS model. Conclusions - the authorities are supposed to control the prices of HC, Foodstuff and Housing and encourage the consumption of HC, Housing, EE accordingly. At the same time, local government should increase the supply of goods connected with housing, HA, HC, and EE so as to attract more consumption from the urban residents in Shandong.

In urban environments, the surface land impermeability fundamentally related to urban growth emphasizes the environmental problems such as the storm water peak flow (so-called the urban flooding) and the pollution. The conventional urban drainage system provides a number of temporary reservoirs intercepting and retaining surface-derived pollutants following their introduction to and deposition upon the impermeable surface. Gully-pots are common features in urban drainage systems in Korea, which were installed for draining rainwater to prevent regurgitation in rainy season and retaining larger particles, hence minimizing pipe blockage problems. When the road runoff conveying sediment enters a gully-pot, the sediment mixes with the gully liquor causing direct pollution of receiving waters. The characteristics of local sediment contamination are usually related to the types of land use activities that take place or have taken place within the area., This study was undertaken to evaluate the spatial and temporal variations of the contamination of gully-pot sediments in Seoul with respect to heavy metals such as As, Cd, Co, Cr, Ni, Pb, Cu and Zn. The heavy metal data were examined according to the land use type. In this paper, sampling sites in Seoul were divided into six groups (commercial area, industrial area, residental area, motor way, rural area, and local pollution).

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.

In less favored areas, it is getting more difficult to manage Satoyama according to aging of rural residents and depopulation. Some support of urban residents are necessary for management of Satoyama. In this paper, the role of Satoyama management activities was clarified through the analysis of the feature of activities for managing Satoyama. The questionnaire and interview surveys were done in order to clarify the actual conditions for management of Satoyama and activities of urban residents who are participating in NPO in Hyogo Prefecture. The results of analysis are as follows. (1)The form of rural-urban exchange in Satoyama is different in each Satoyama. (2)The urban residents are contributing to the region very much on both sides of the manager and the visitor in Satoyama. (3)Many urban residents visit Satoyama for the purpose of enjoying the variety of nature and culture programs in rural area. (4)There are some urban residents who participate in activities for managing Satoyama even if Satoyama is far from their residence. So it is important for rural residents to arrange the condition that they can visit rural area without difficulty.

The number size distribution of urban aerosols ranging from 0.02 to 20 ${\mu}{\textrm}{m}$ in diameter was measured by using a scanning mobility particle sizer (SMPS) system and an aerodynamic particle sizer spectrometer (APS) at Seoul from November 30,2001 to January 14, 2002. The gaseous species such as CO, NO, NO$_2$, and $O_3$ were also continuously monitored. The daily average concentration of urban aerosols sorted into three groups (0.02~0.1 ${\mu}{\textrm}{m}$, 0.1~1 ${\mu}{\textrm}{m}$ and 1~10 ${\mu}{\textrm}{m}$) and the typical number, surface, and volume distributions of urban aerosols were discussed in this paper. The weekly variation of aerosol concentration was compared with those of gaseous concentrations. relative humidity, and visibility. The results showed that the particle number concentration seemed to increase in the morning and the number concentration of fine particles less than 1 fm in diameter seemed to increase when the concentrations of CO, NO, and NO$_2$ were high. The number concentration of fine particles was relatively high when the relative humidity was greater than 70％ during the increasing period of relative humidity. The visibility was weakly correlated with the concentration of aerosols ranging 0.1 to 1 ${\mu}{\textrm}{m}$, and the number size distribution for high visibility episode was apparently different from that for low visibility episode.

The urban renewal type redevelopment project is a project to improve the urban environment for the recovery of urban functions and revitalization of commercial districts in commercial and industrial areas. Urban regeneration projects are not progressing smoothly. The urban renewal type is not so for landowners, who require a high level of professional knowledge and experience to carry out smooth projects. In addition, the core part of business conflicts can be seen as the problem of management and disposal methods. Therefore, as landowners, etc. become the actual subjects, the public will take charge of project execution, but all development gains and losses will be attributed to the owner of the land, etc.

With global warming and the rapid increase in urbanization accompanied by a concentration of population, the urban heat island effects (UHI) have become an important environmental issue. In this study, rooftop greening and permeable asphalt pavement were selected as measures to reduce urban heat island and applied to a simple virtual urban environment to simulate temperature change using ENVI-met. A total of five measures were tested by dividing the partial and whole area application of each measure. The results showed that the temperature range of the base experiment is 33.11-37.11 ℃, with the UTCI comfort level described as strong heat and very strong heat stress. A case applied permeable asphalt has a greater temperature difference than a rooftop greening case, the larger the area where each condition was applied, the greater the temperature change was.
