objective: soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. so, this research has been done for achieving this purpose. methods: this...

the present study was carried out in kharkeh research station, kurdestan province, western iran to investigate the effects of the change in land use on the degradation of mol-lisols, their organic carbon content, clay mineralogy and k+ status. the study area was partly under cultivation (for over 40 years) and partly preserved as rangelands. the re-sults revealed that mollisols are the dominant...

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...

A major challenge in gauging long-term and cumulative impacts of fisheries management on coastal fishing communities is the lack of understanding of the interactions between changes in fish stocks and waterfront land uses. This study examines these interactions in the New Bedford/Fairhaven area using parcel level data and geographic information system (GIS) tools. Logistic regression models wer...

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...

With the development of global changes, researchers from all over the world attach attention to land use changes increasingly, and large scale land use changes which have resulted from urban expansion catch people’s eyes. In this paper, urban expansion and their spatial and temporal variability of the Beijing city has been studied over a period of 21 years (1984–2005) via statistical classifica...
