City growth and environmental difficulties last decades leads the art of urban design and development think more precisely and new approaches for conserving environment and developing urban areas have been evolved.The present study deals with concepts related to ecology in the city and in particular the theory of Ecological Urbanism and its criteria is expressed. Also theory and characteristics...

The rapid expansion of urban construction land has become the major characteristic of urban land-use change in China today. Meanwhile, the rapid urbanization process has led to the great changes of urban landscape in China, and it also has had certain impacts on environmental factors such as climate, soil, hydrology, biodiversity, etc., then it has made the overall ecological environment deteri...

quantifying urban landscape is fundamental for monitoring and assessing ecological and socioeconomic consequences of urbanization. expansion of roads is a significant factor driving urban landscape change. the aim of this research is quantifying impacts of roads on isfahan city landscape. to achieve this aim, land use map of isfahan was created in 6 classes: urban, green spaces, agricultural, b...

It is widely believed that urban ecological landscape regards the city to be an ecosystem built by human activities and supported by natural and man-made functions and processes over time. In the past, human communities have selected their residing places and designed their cities by paying attention to natural environmental resources. The profound influence of technology and industry has broug...

Urban ecological security is the basic principle of national ecological security. However, analyses of the spatial and temporal dynamics of ecological security remain limited, especially those that consider different scenarios of urban development. In this study, an integrated method is proposed that combines the Conversion of Land Use and its Effects (CLUE-S) model with the Pressure–State–Resp...

introduction urban landscape is experiencing rapid changes which put all urban domains under pressures. these processes revolutionize urban landscape into spaces without ecologic values. the sustainability of green patches and corridors has been scathed by lack of ecological approaches in planning and design. therefore, urban green spaces structures and functions have been damaged. green spaces...

This study investigated land use changes, and their ecological effects in Wuhan (1987-2005). Remote Sensing techniques extracted land use data, whilst the spatial analyst software, Fragstats quantified ecological metrics at both landscape and class levels. The results showed increased urban and agricultural land uses (1987-2005); with urban land increasing more than 250 percent. This was largel...

As a fundamental part of greenspace, urban water landscape contributes greatly to the ecological system and at the same time supplies a leisure area for residents. The paper did an analysis on the number of aquatic plant communities, the form of water spaces, and water quality condition by investigating 135 quadrats (90 at amphibious boundary and the land, 45 in the water) in 45 transects of 15...

Applied with remote sensing, GIS, and mathematical statistics, the spatial-temporal evolution characteristics of urbanization expansion of Yantai city from 1974 to 2009 was studied. Based on landscape pattern metrics and ecological risk index, the landscape ecological risk from the landscape pattern dynamics was evaluated. The results showed that the area of urban land increased by 189.77 km(2)...

the distinguishing characteristic in the third millennium is planning based on principles of sustainable development in line with nature and all activities related to urban issues. ecological concepts and consequently ecological park refers to a comprehensive and integrated set of measures which create coordination, balance between the constituent elements of the park in order to establish sust...
