Though the method of citizen participation in urban planning is quite well established, for a specific segment of residential environment, however, existing participation system has not coped adequately with the issue. The specific residential environment has detailed aspects that need positive and high level involvement of the citizens in participating in all stages and every field of the plan. One of the best and systematic methods to obtain a more involved citizen is through a citizen workshop. To get a more “educated” citizen who participates in the workshop, a special session to inform the citizen on what was previously gathered through a survey was revealed to be prerequisite before the workshop. The computer support system is one of the best tools for this purpose. This paper describes the development of the computer support system for residential environment evaluation system, which is an essential tool to give more information to the citizens before their participation in public workshop. The significant contribution of this paper is the educational system framework involved in the workshop on the public participation system through computer support, especially for residential environment. The framework, development and application of the computer support system are described. The application of a workshop on the computer support system was commented on as very valuable and helpful by the audience as it resulted in greater benefit to have wider range of participation, and deeper level of citizen understanding. 展开更多

Cultivated land transition and its driving mechanism are the hotspots among studies on land use change. In this study, we constructed a framework to study the driving mechanism of cultivated land transition from the quantitative perspective. Based on the vector data of land use in 1990, 2000 and 2009 of Yantai Proper, Shandong Province China, 11 explanatory variables were chosen from two aspects: the elevation, slope, cost distance to major water area and cost distance to minor water area, which presented physical factors; cost distance to district center, cost distance to town center, cost distance to city expansion center, cost distance to major roads, cost distance to city roads, cost distance to county roads and cost distance to rural roads, which presented the socio-economic factors. Combined with spatial analysis tools and Logistic regression analysis model, we construct Logistic regression analyses with four objectives that were urban construction land, rural residential land, orchard and other lands. The results show that, cost distance to district center, cost distance to town center, cost distance to city expansion center and cost distance to city roads are the significant explanatory variables for the transition of cultivated land into urban construction land. The main explained factors on the transition of cultivated land into rural residential land are slope, cost distance to town center, cost distance to county roads and cost distance to rural roads. Slope, cost distance to minor water area, cost distance to town center, cost distance to county roads and cost distance to rural roads are the significant explanatory variables for the transition of cultivated land into orchard land. Elevation, slope, cost distance to major water area and cost distance to minor water area are the main explanatory variables on the transition of cultivated land into other land uses. 展开更多

The cooling effects of urban green vegetation cover, which can help decrease LST (land surface temperature) in urban area. When air temperature decreases, the electricity consumption of household will also mitigate loading. Meanwhile, that lack of assessment of green vegetation coverage impact to LST and electricity consumption, so that it could not clearly quantify the environmental contribution of green coves. In Taipei city, for example, FVC (fractional vegetation cover) value and LST was collected from Aster satellite remote sensing images, and data of household electricity consumption was acquired from Taiwan Power Company. Based on these three factors, it analyzed relative model. In the urban area, fractional vegetation cover might influence with land surface temperature and electricity consumption. The result shows that when the value of fractional vegetation cover is low, the air temperature is high. While fractional vegetation cover is increase, not only the land surface temperature is decreasing but the electricity consumption is also reducing. This study hopes can be the reference materials for the future metropolis plan and to inhibit the spread of urban thermal environment. 展开更多

Recent studies by the Hong Kong Observatory show that the urban centre of Hong Kong has considerable Urban Heat Island (UHI) effect that arises from the different thermal properties between urban and the surrounding rural areas. The studies have also shown that the urban-rural temperature difference or UHI intensity in the urban centre of Hong Kong can be greater than 10℃. However, the characteristics of UHI in Hong Kong would not be unique were it not for its complex topography and the significant spatial variation in the degree of urbanization within the territory. Making use of the extensive spatial coverage of the automatic weather stations operated by the Observatory, this study attempts to document the spatial variation of the characteristics of UHI effect in Hong Kong in summer and winter through cases studies. Cases in summer and winter with meteorological conditions typical for high UHI effect (that is, clear sky, light wind and stable atmospheric condition) are selected for the study. The characteristics of UHI effect in terms of the daytime warming rates, nocturnal cooling rates and diurnal temperature ranges at the selected automatic weather stations are analysed. The territory of Hong Kong is then classified into different categories according to the identified characteristics with a view to portraying the spatial morphology of UHI effect in Hong Kong. 展开更多

This paper tries to discuss everyday life and its relation to urban experiences in different aspects of Taipei City in Human Condition, performed by Greenray Theatre in Taiwan since 2001. The serial play, including six parts,1 displays the life of ordinary people, primarily the middle and labor classes. Historically, Human Condition tells about Taiwan Residents' life from the period of Japanese occupation in Taiwan to the present day. The public's everyday life and their cultural activities are delicately represented on the stage. Human Condition especially focuses on people living in Taipei city, the capital and most populated place of the country. In different historical periods and political atmospheres, the characters' economic and social activities, nostalgic feelings about the past, passions for love and friendship, and awakening of fighting for humanity and freedom construct their social positions as well as establish different aspects of Taipei. We can see the transformation of the city by means of people's social relationships and economic activities. Drawing on Henri Lefebvre's concept of everyday life as rhythmic movement and spatial practice in the process of urbanization, this paper aims at studying the characters' social practice that defines their position and formation of identity within place. Human Condition unravels the characters' connection and disconnection from place in each period of Taiwan's historical and political conditions. The life in Taipei differs from each historical, economic, and political system that defines people's attitudes and perspectives toward this land. The characters within every historical background and political system tell us what Taipei represents and symbolizes to people. The transition of Taipei produces impacts on people that endow them with different personalities and perspectives toward life. As globalization invades into this city, the definition of human in city life has to be reconsidered. As a place of encounter, accumulation of cultural hybridity in Taipei formulates multiple dispositions and social structures. By analyzing the characters represented in every historical period of Taipei, this article interrogates to what extent of "in-place" or "out-of-place" of the characters is interpreted in this space and, in the progress of urbanized development of Taipei, what the value is to affect and connect people's relationships. 展开更多
