Urban landscapes form the main parts of the city. One of these spaces is urban streets, in whichsocial interactions and urban vitality reach its maximum quality and quantity. One of the principles and properties ofurban landscape design is its intelligibility. A viewer who takes a look at an intelligible city and knows it can attract newemotional manifestations of city without damaging its orig...

Urban sprawl is a hot topic of global concern with increasing dramatically and impact on ecological environment. But there is not a mature method to explain the detail of process of urban sprawl and dynamic changes. In this paper, the dynamic changes of urban is studied based on 1980, 1988, 1994, 2000 and 2005 five remote sensing images of Shenzhen. It is distinguished three types including inf...

Urban planning exerts influences on environmental, social and economic system related with the city. Processes of land transformation and city growth determine radical changes in urban landscape morphology and as a consequence they affect air temperature and energy exchange. The urbanization can bear on local climate more intensively than the global warming does. This is due to the rapidity of ...

Bio-cultural landscapes are characterized by anthropogenic pattern features, of which the measurement constitutes a key step in landscape analysis. Metrics and strategies for this measurement of anthropogenic patterns and their dynamics are discussed, considering the pattern/process paradigm, the patchcorridor-matrix model and the complementarity of landscape composition and configuration as co...

Urbanization is the most drastic form of land use change affecting biodiversity and ecosystem functioning and services far beyond the limits of cities. To understand the process of urbanization itself as well as its ecological consequences, it is important to quantify the spatiotemporal patterns of urbanization. Based on historical land use data, we characterize the temporal patterns of Phoenix...

BACKGROUND Habitat loss is one of the principal causes of the current pollinator decline. With agricultural intensification, increasing urbanisation is among the main drivers of habitat loss. Consequently studies focusing on pollinator community structure along urbanisation gradients have increased in recent years. However, few studies have investigated how urbanisation affects plant-pollinator...

the expansion of major cities regardless of the scientific planning principles has led to theemergence of negative urban development impacts in iran such as the degradation of natural resources andvarious forms of pollution. undoubtedly, urban rivers can enhance the ecological value of the earth to anoptimal extent. however, to benefit from these potentials, appropriate planning looks inevitabl...

Urban open spaces are invaluable assets in maintaining ecological health in a highly developed urban matrix. Unfortunately, habitat values and ecological quality of these areas are often challenged by consecutive urbanization. The assessment of changing structure and function of an urban open space system is crucial in maintaining livable cities. General characteristics and types of open spaces...

Over the last 50 years, the world has faced an impressive growth of urban population. The walled city, close to the outside, an “island” for economic activities and population density within the rural land, has led to the spread of urban life and urban networks in almost all the territory. There was, as said Margalef (1999), “a topological inversion of the landscape”. The “urban” has gone from ...
