Influenced by the only-child policy, traditional old-age support system fails to adapt to new social situation, the institutions have become major subjects in the future old-age support system. Researches on the elderly-fi t architectural design have achieved many fruits, but those on the landscape design of the elderly community has been less reported. This paper studied landscape design of the old-age support institutions from the perspective of both theory and practice, and tried to explore the spatial layout of environmental landscapes in the elderly community. On the basis of sorting out specifi c psychological needs of the elderly group in China and their needs for the layout of landscape spaces, this paper proposed some effective solutions in view of successful elderly communities in overseas countries, then analyzed the development of elderly communities in China, so as to fi gure out landscape design approaches capable of promoting physical and mental health of the elderly group in the old-age support institutions.展开更多

According to the relationship between location and water, die waterfront setdements in northern Jiangxi were classified into tiiree categofies. The structuial commonalities of the three kinds of waterfront settlements were cleady interpreted. On this basis and combined with the field research data and relevant data, the characteristics of the waterfront setdements in northern Jiangxi were summarized： treating water as the main skeleton, choosing location by the distance ￡com watet, magnetic effect and organic textute.

However, the old town of cities has gradually been forgotten by people and its environment is becoming increasingly harsh. The old town usually has diversified space and function. As an important part of the old town, the street canyon that is closely related to human settlements is a public space where people communicate and do activities. Therefore, research on microclimate-based improvement of the street canyon in the old town is of great significance. Six typical street canyons in the White Stupa Temple area of Beijing were selected for research to explore spatial characteristics of the street canyon. Microclimate factors such as temperature, humidity, wind speed, and solar radiation were measured on the spot in summer. These factors were combined with two microclimate assessment indexes of physiological equivalent temperature(PET) and wet bulb globe temperature(WBGT) to evaluate the microclimate of the street canyon. In the analysis of the measured data, the mean value comparison method was used to analyze the average values of the microclimate factors in different time periods. Spatial layout of microclimate included the orientation of the canyon, the ratio of the canyon height to canyon width, and green coverage of the canyon, and an in-depth study was made on the coupling relationship between the spatial layout and the microclimate of the canyon. Research results can provide an optimization strategy for the transformation design of the street canyon in White Stupa Temple area, and provide a scientific reference for the research on spatial layout and microclimate improvement in the old town, so as to improve the living quality of residents in the old town.展开更多

Based on the statistical data of field research, this paper chooses 1264 towns in 51 counties as the scope of evaluation, selects eight indices in the evaluation index system which includes post-disaster population scale, population density, urbanization rate, the percentage of migrant workers, death rate by earthquake, the percentage of minorities, elevation-slope integrated terrain and comprehensive geological condition. Besides, this paper uses AHP supported by entropy technique and fuzzy membership function model to calculate the suitability evaluation index and then divides the disaster areas into five types： highly suitable area （area accounted for 11.03%）, relatively highly suitable area （15.29%）, moderately suitable area （29%）, less suitable area （30.08%） and unsuitable area （14.6%）. According to the result of suitability evaluation, this paper puts forward several suggestions for the reconstruction as follows： the urban system and the building of new countryside should be guided by the suitability evaluation subareas; post-earthquake reconstruction avoids zones near Longmenshan fracture and high-mountain gorge areas as far as possible; the scale of population and settlement should not exceed the capacity of resources and environment; population should be resettled as close as possible by considering adequately the heterogenicity and homogeneity of regional nationality culture characteristics; densely resettle the people at plains and hilly areas; encourage the migrant workers settle in the working place with their families voluntarily; and urban system reconstruction such as industry layout and important projects of lifeline should be guided by the spatial layout suitability evaluation.展开更多
