This study presented the analyses of temporal and spatial change of land use dynamics and landscape pattern in the Huai river basin during the period 1986-2005 by using the land use dynamic degree model, the land use centroids and the landscape metrics; and discussed the driving forces of land use change over the period employed the gray relational analysis method. The main results showed that:...

Located in Qinghai Province of China, the Three Rivers Headwaters Region is the source region of the Yangtze, Yellow and Lantsang Rivers, and plays an important role in biodiversity conservation and regulating water supply. Despite many efforts on land use change in Qinghai, knowledge of the spatial variation of land use change is still lacking. This study examines the patterns of land use chan...

Tibetans view the environment as an interrelated balance upon which humans and nature coexist. Overconsumption of resources is discouraged, and the taking of life is forbidden by Buddhist practice. However, as traditional people meet the modern world, checkerboard patterns are carved into forested mountain slopes, pollution runs freely in once pristine waters, erosion lays grasslands bare, and ...

This paper describes and evaluates the application of the interactive landscape visualisation system Biosphere3D in a case study of cliff erosion in Norfolk, on the eastern coast of England. The study builds upon previous work on coastal zone management by the Tyndall Centre for Climate Change Research at the University of East Anglia. Biosphere3D is an open-source system, which supports multip...

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...

Aims and Background: The present study purpose to investigate and predict the changes of metrics and Landscape change processes in the Gorganrood watershed in Golestan province.  Methodology: First, land cover maps were prepared in 1990, 2000, 2010 and 2020. Then predict land cover changes for future conditions, under two scenarios (1) continuation of the current trend of change for 2040 and (...

Land cover has rapidly changed due to the relatively high population density, high rate of seasonal and permanent migrants, favorable conditions of natural and cultural, frequency of industrial units, coastal border and harbour and great rate of construction in the mazandaran province in recent years. Land cover changes are led to fragmentation, perforation, dissection, shirinkage, attrition an...

The composition of a landscape is a fundamental indicator in land-cover pattern assessments. The objective of this paper was to evaluate a landscape composition indicator called ‘landscape mosaic’ as a framework for interpreting land-cover dynamics over a 9-year period in a 360,000 km study area in the southern United States. The indicator classified a land parcel into one of 19 possible landsc...
