The urban transformation of the planet has spurred interest across a wide variety of disciplines in the fundamental changes to human society and the environment that result from urbanization. Landscape ecology is no exception. Since the late 1980s, the number of papers devoted to the study of the ecology of urban landscapes has risen dramatically. This trend prompted the question I address in t...
The Historic Urban Landscape (HUL) of the city is shaped by several layers of explicit and implicit contextual values that distinguish it from other landscapes. Sustaining these contextual characteristics and values as a whole is made possible by a thorough understanding and putting in place measures to preserve and enhance them. This article, in the absence of methodologies to delineate an...
The key focus of this paper is to establish a procedure that combines the use of Geographical Information Systems (GIS) and remote sensing in order to achieve simulation and modeling of the landscape impact caused by construction. The procedure should be easily and inexpensively developed. With the aid of 3D virtual reconstruction and visualization, this paper proposes that the technologies of ...
Green space plays an important role in sustainable urban development and ecology by virtue of multiple environmental, recreational, and economic benefits. Constructing an effective and harmonious urban ecological network and maintaining a sustainable living environment in response to rapid urbanization are the key issues required to be resolved by landscape planners. In this paper, Nanchang Cit...
This study intends to identify both general trends and subtle patterns of urban land changes of the past three decades in metropolitan Kansas City area. Landsat images were used to generate time series of land cover data from the early 1970s to the early 2000s. Based on remotely sensed land cover data, landscape metrics were calculated. Both the remotely sensed data and landscape metrics were u...
Urbanization is a key global driver in the modification of land use and has been linked to population declines even in widespread and relatively common species. Cities comprise a complex assortment of habitat types yet we know relatively little about the effects of their composition and spatial configuration on species distribution. Although many bat species exploit human resources, the majorit...
Cities are home to more than half of the world population. Cities have been the centers of economic and social developments, as well as sources of many major environmental problems. Cities are created and maintained by the most intense form of human-nature interactions. Cities are spatially extended, complex adaptive systems—which we call landscapes. The future of humanity will increasingly rel...
trifolium spp. are native plants in iran exhibiting good ground cover po-tential. salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. the main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...
Urbanization has been cited as an important factor in worldwide amphibian declines, and although recent work has illustrated the important influence of broad-scale ecological patterns and processes on amphibian populations, little is known about the factors structuring amphibian communities in urban landscapes. We therefore examined amphibian community responses to wetland habitat availability ...
Hann, Wendel J.; Wisdom, Michael J.; Rowland, Mary M. 2003. Disturbance departure and fragmentation of natural systems in the interior Columbia basin. Res. Pap. PNW-RP-545. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 19 p. We integrated landscape data from science assessments of the interior Columbia basin (basin) into one variable that func...
