large scale land use/cover changes and habitat fragmentation is a major factor in the distribution and functioning of ecosystems. for analysis the relationship between land use changes and their impacts on biodiversity, land cover and land use information is needed at different scales. the main goal of this study was to quantify the land use/ cover changes in arasbaran biosphere reserve, northw...

land use change is driven by interaction in space and time between humans and the environment that can be captured by computer simulation models (veldkamp and verburg, 2004). in the last few decades, land use change models have played an important role in understanding the causes, mechanisms and consequences of land use dynamics. sleuth is an open source cellular automata based land use change ...

green belt is defined as a narrow green area surrounding an urban area. shiraz green belt has been developed through 9 projects with a variety of purposes since 2005. the development of green belt is being considered in a number of iranian cities, and therefore, investigation of shiraz green belt’s purposes and challenges could contribute to an appropriate planning by decision makers. the main ...

in recent years, changes in catchments water balance due to land use management have become the main concern of water resources authorities in iran. due to rapid population growth and land use changes, especially construction of taleghan dam, taleghan catchment has undergone rapid changes such as urban development, declining of rangelands, and deterioration of environment and erosion of soil re...

BACKGROUND Although researchers have explored associations between mixed-use development and physical activity, few have examined the influence of specific land uses. PURPOSE This study analyzes how the accessibility, intensity, and diversity of nonresidential land uses are related to walking for transportation. METHODS Multinomial logistic regression was used to investigate associations be...

planners have regarded understanding urban use per capita since the beginning of new thinking of urban development. this was stared with its pragmatics toward primary comprehensive urban plans and became a source for urban development plans that have tried to adapt per capita and standards with country’s conditions. iran's supreme council for planning and architecture, determined standards per ...

Fleas associated with different rodent species are considered as the major vectors of bubonic plague, which is still rampant in different parts of the world. The objective of this study was to investigate the contribution of land use to rodent flea load distribution at fine scale in the plague endemic area of north-eastern Tanzania. Data was collected in three case areas namely, Shume, Lukozi a...

Training of object-based land cover classifications is often performed with objects generated via image segmentation. The objects are commonly assumed to be thematically pure or excluded from training if a mixture of classes is associated with them. However, excluding mixed objects has several consequences such as reducing the size of the training data sets. In this study, it is hypothesized th...
