development of remote sensing (rs) and gis techniques and that of landscape metrics in the late 1980s have caused to introduce a new dimension in the landscape ecology arena (the relationship between spatial patterns and ecological processes). however, scale dependence of some of landscape metrics and rs systems of different spatial resolution has resulted in particular attention into selection...

One of the most important natural factors and critical facilities in Tehran is presence of AlborzSlopes River-Valleys which have been considered as natural tourist places for citizens since a long time ago, especiallyin hot summers and play effective role in creating a balance between manmade and natural spaces. Importance ofthese river-valleys as ecological pathways is enhanced with the increa...

Remote sensing imagery has been widely used in urban growth and environment analysis with many effective and advanced strategies being developed. However, most of these approaches are separated from each other. There is an urgent need to combine different modules into some practical processing chains. Firstly, we present a comprehensive analysis of key processing chains in applying remote sensi...

Urban ecosystems are becoming increasingly important as nodes of interaction between humans and nature. Sustainable management of urban ecosystems is therefore a crucial issue that needs to be analysed. The aim of this paper is to explore if adaptive co-management may be a viable approach for managing ecosystem resilience of a biodiversity-rich urban landscape in Stockholm, called the National ...

Urbanization and the resulting changes in land cover have myriad impacts on ecological systems. Monitoring these changes across large spatial extents and long time spans requires synoptic remotely sensed data with an appropriate temporal sequence. We developed a multi-temporal land cover dataset for a six-county area surrounding the Seattle, Washington State, USA, metropolitan region. Land cove...

This research simulates the urban growth and therefore the landscape change of a mountain city of Chongqing, China through a Cellular Automata (CA) based model of SLEUTH. The fundamental data were four Landsat TM images of 1978, 1988, 1993, and 2001 which were utilized for generating maps of land use, road networks, and urbanized area. Three alternative development scenarios, including business...

Urban expansion increases fragmentation of the landscape. In effect, fragmentation decreases connectivity, causes green space loss and impacts upon the ecology and function of green space. Restoration of the functionality of green space often requires restoring the ecological connectivity of this green space within the city matrix. However, identifying ecological corridors that integrate differ...

the notion of sustainable development has rapidly gained considerable attention since the lastdecades of the twentieth century. it has become a locus for global paradigm shift on environment and development issues particularly after rio conference in 1992. the comparative analysis of agenda 21 and major un documents, mdg, and rio+20 as well as some major sources are made to provide a context fo...

Water as one of the most essential natural elements of landscape and consequently urban landscape from yesterday till today has had a great impact on the formation and effectiveness of urban spaces and its various effects have always stimulated human tendency towards beauty. It should be noted that the existential values ​​of water are not merely aesthetic, rather it goes back to the deepest an...
