Mark Francis, FASLA is professor of landscape architecture at the University of California, Davis. Trained in landscape architecture and urban design at Berkeley and Harvard, his work has focused on the use and meaning of the built and natural landscape. Much of this research has utilized a case study approach. He developed the case study method for the Landscape Architecture Foundation and ser...

suffering from disorder and chaos, tehran is a city capable of introduced as one of the most beautiful cities in the world for its historical and geographical capacities. unfortunately, in the modern era and after the islamic revolution when urban development destiny started to depend on engineers due to their increasing authority in urban management, culture role was undermined and tehran unde...

Landscape patterns are closely related to ecological processes. Different spatial scales and research methods may lead to different results. Therefore, it is crucial to choose suitable research methods when studying different landscape patterns and ecological processes. In the present study, the methods of source-sink landscape theory were applied to the interactions between urban landscape cha...

Evapotranspiration estimation has benefitted from recent advances in remote sensing and GIS techniques particularly in agricultural applications rather than urban environments. This paper explores the relationship between urban vegetation evapotranspiration (ET) and vegetation indices derived from newly-developed high spatial resolution WorldView-2 imagery. The study site was Veale Gardens in A...

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...

As complex dynamic systems, urban landscapes emerge from the local interactions of socioeconomic and biophysical agents and processes. These complex systems are highly heterogeneous, spatially nested, and hierarchically structured (Wu and David 2002). They are prototypical complex adaptive systems, which are open, nonlinear, and highly unpredictable (Levin 1998, Portugali 2000, Gunderson and Ho...

We present an image analysis flowchart, based on the use of object-oriented software (eCognition). The maps obtained identify the urban landscape at different scale levels (urban areas and buildings – settlements) and at different organization levels (dense, discontinuous or low-density urban landscape). A particular effort has been made to assess the quality of the results (confusion matrix, K...

By considering certain factors like those mentioned by Ian Thompson (2005) in his definition of landscape, i.e. ecology, community and delight, in designing landscapes, one can find the vocation more applicable and useful. City rivers can play a very important role with regard to such values. In fact, the presence of nature and wildlife could not only be the lifeline of a city, but also a facto...
