The construction of an ecological city must be launched in the dual spatial criteria: in city (urban district) criterion—optimizing the city ecosystem; in city-region (city territory) criterion—optimizing the city-region ecosystem. Luoy-ang has the bright characteristic and the typical image within cities of China, and even in the world. The construction of an ecological city in dual spatial criteria—the city and the city-region—has the vital significance to urbanization advancement and sustainable development in Luoyang. In city-region criterion, the primary mission of Luoyang’s ecological city construction is to create a fine ecological environment platform in its city territory. In city criterion, the basic duty of Luoyang’s ecologic city construction is to enhance the ecological capacity and benefit of the central city.展开更多

The fast developing and uncontrolled urbanization is behind the development of some negative side effects on the urban environment. Many studies demonstrate the ability of remote sensing and GIS (geographic information system) to monitor urban environment quality. Casablanca, Morocco's economical capital is facing a fast growing demographic development amplified by a massive rural depopulation and all this in an anarchic way. This growth of increased urban activity comes often with the proliferation of informal settlement and shantytown to the detriment of farming areas and green spaces. This study is made possible by using a SPOT-5 image of Casablanca city, taken March 16, 2004 merged with 2.5 m spatial resolution and census data. Indicators were defined and listed in social, economic and environmental categories. An index of environmental quality in Casablanca city for the 17 urban municipalities was calculated after the standardization and weighting of indicators used. The results may be useful to city managers and planners who are concerned with urban environment quality issues and sustainable development.展开更多

By analyzing Agadir's urbanistic and architectural content thorough ages, we find ourselves involved in an enthralling and passionate debate concerning two important aspects. The first is the historical temporality of the city's architectural and urbanistic changes. In other words, it is the different architectural transformation related to the political transmutations that Agadir has witnessed since the Portugal settlement until the after earthquake of 1960. While the second is about the perception toward the architectural oeuvre deeply settled in the territory and the memory of the city's designers. This aspect is linked to the society's perception toward the architectural-urban transformations in their territory. In our paper, we are going to focus on two major architectural and urbanistic ages in the history of Agadir. The first period we are going to approach is the architectural and urbanistic features of Agadir during French settlement. The second period is Agadir's architectural renaissance after 1960s earthquakes. Since the core of our study is the architectural acts, it is definitely a matter of interpretation related to the philosophical, mental and ideological representation of the city's architecture and urbanism either by those who artistically invented Agadir during colonialism or those who reinvented Agadir after 1960s earthquakes. Do urbanism and architecture represent for Agadir, a power, a doctrine or a savoir-faire? Can we affirm that Agadir's architecture is truly reflecting the image of its society? Is this society in itself immersed sufficiently in its architecture? Several hypotheses are possible in this research. Nevertheless, the fact that in this paper we use communication as a vehicle to establish a dialogue between arts, politics and socio-ideologic and territorial governance makes us recognize the different bridging relationships between the architectural action, the political and urbanistic content represented in the architectural expression. It also helps us to discover and analyze the ideologies that lead the architects during their conception. Finally, is this architecture which normally must represent the society in tempo-spatial territory admitted by the local citizens? All these are lines of research we are going to shed light on in this paper.展开更多

Focusing on the features of LA's geologic conditions and civil circumstances, we argued that the relationship between LA's low-density pattern and car dependence is more involved than previously deemed simple causality. The low density should be primarily credited to the spacious requirement of the mining industry, frequent earthquakes and multiethnic population of the city. Off reserves in LA fueled its economic boom and fast urbanization that coincided with the start of mass production of cheap cars, and cars became medium-priced consumables for average families. Politicians preference for short constrnction-period projects enabled fast establishment of LA's highway infrastructure. The popularity of car use in return faciliatated further development of the low-density pattern of the city. The low-density urban form and car dependence created environmental and social problems for LA. Looking at P. R. China's motorization and urban development, we found that the trajectory of Beijing's motorization between 197g and 2003 coincides with that of the U.S. in the 1910s and 1920s. Lessons from LA's urban and transportation development should be suggestive to China's urban and transportation planning.展开更多
