Application of genetic algorithms to problems where the fitness landscape changes dynamically is a challenging problem. Genetic algorithms for such environments must maintain a diverse population that can adapt to the changing landscape and locate better solutions dynamically. A niching genetic algorithm suitable for locating multiple solutions in a multimodal landscape is applied. The results ...

This paper addresses the long-standing problem of generating fractal mountains with rivers, and presents a partial solution that incorporates a squig-curve model of a river’s course into the midpoint-displacement model for mountains. The method is based on the observation that both models can be expressed by similar context-sensitive rewriting mechanisms. As a result, a mountain landscape with ...

Urbanization brings biophysical changes in the composition of the landscape. Such change has an impact on the thermal environment locally. The urban mosaic of land use and land cover is thus characteristically composed of local climate zones. The spatial variation in the land surface temperature across specific zone is studied for Bhopal city. The objective of the study was to understand how th...

Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...

Urbanization is developing unprecedentedly on a global scale. One of the chief repercussions of urbanization, caused by man-made alterations in land-use/land-cover (LULC), is the formation of urban heat islands. Albeit, differences among landscape structures and its accompanied effects on the environment are mostly neglected. Accordingly, the main objective of this study is to survey the variou...

Habitat and ecosystem fragmentation and, consequently, the loss of landscape connectivity are major causes of biodiversity destruction, leading to disruption of material, energy, and information flow at the landscape scale. Given the importance of this issue, the current study aimed to evaluate the ecological connectivity and spatial planning of Qazvin Province, in order to re-establish and pro...

Landscape can be explained both fro� positivistic and constructivistic positions. Confusion and contradictions around the landscape paradig� arise fro� different definitions (e.g. geoco�plex versus cultural landscape), the role of landscape boundaries and landscape classifications. �he deli�itation and classification of (natural) landscape units in Saxony (Ger�any), the concept of landscape fun...

linear green infrastructures along rivers and canals serve different functions: green corridors, or ecological network, maintain biological diversity, improve water quality, and provide areas for fauna and flora to grow and thrive. greenways connect people with landscape resources and serve as recreational areasthat are easy to use and accessible to the greatest number of potential human users....

With the acceleration of urbanization, human needs to connect with the nature and experience the aesthetic qualities such as landscape aesthetic, fresh air, topographic diversity and green infrastructures. Hence, landscape aesthetic quality is regarded as a valuable source of conservation. The purpose of landscape visual quality assessment is to identify the criteria for preserving and rehabili...
