The paper seeks to highlight how the character and values of marginal landscapes can be considered examples of the “third landscape” and how they can enable the mapping of tangible and intangible change (and its relative effects) through the selection of appropriate spatial indicators. A Dynamic Spatial Decision Support System was constructed to help identify the complex values characterizing a...

Ecological security is an important research topic, especially urban ecological security. As highly populated eco-systems, cities always have more fragile ecological environments. However, most of the research on urban ecological security in literature has focused on evaluating current or past status of the ecological environment. Very little literature has carried out simulation or prediction ...

Riparian plants incorporate nitrogen (N) from aquatic, terrestrial, and atmospheric sources, and their stable isotope compositions (dN) may reflect land use impacts on N sources and transformations over scales of sites to watersheds. We surveyed leaf dN values of 11 common riparian tree, shrub, and herbaceous species from 20 streams and rivers spanning three fifth-order watersheds in northern U...

Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...

BACKGROUND Although widely used, area-based deprivation indices remain sensitive to urban-rural differences as such indices are usually standardised around typical urban values. There is, therefore, a need to determine to what extent available deprivation indices can be used legitimately over both urban and rural areas. METHODS This study was carried out in Brittany, France, a relatively affl...

urban space can be the most successful public arena in this century if employ the potentialsfor collective cooperation in creative ways in order to provide further services. the theory of creative city tries tostrengthen the qualities which enhance the image of a city for the citizens and create a dynamic city in terms of cultureand intercultural learning. therefore, the existence of generator,...

in our present research, we focus on the modeling of airflow related to natural disasters, such assand accumulation, with urban form studies. the objective is to find which urban form can promote sand passing andreduce as much as possible stagnation of sand in the building area (streets, alleys, etc.). the urban form design will bediscussed through the simulation of airflow by using computation...

S ince the 1990s, China has undergone astonishing economic growth, and its extensive urbanization has become one of the most striking development signatures anywhere in the world. With the world's largest urban population, China's urbanization experience provides meaningful insights on future urban development in other countries. 1 Because China has an extremely low per-capita land area, constr...
