Inhabitants near Poyang Lake, in the Central Yangtze River Basin, China, are vulnerable to loss of life and livelihood because of the interactions of flooding and land-use policies and decisions. We analyzed implications of land-cover patterns for vulnerability to flooding in the Poyang Lake Region. Land-cover and change were mapped using multitemporal Landsat TM/ETM images at high and low wate...
Remote sensing has been widely used for mapping land cover and is considered key to monitoring changes in forest areas in the REDD+ Measurement, Reporting and Verification (MRV) system. But Remote Sensing as a desk study cannot capture the whole picture; it also requires ground checking. Therefore, complementing remote sensing analysis using participatory mapping can help provide information fo...
Land use is one of the basic factors for controlling the hydrologic behavior of watersheds. Therefore, it is generally assumed that land use change is the cause of variation in hydrological dynamic of watersheds. In this paper, the land use effect in present and optimum conditions on sedimentation of watershed was studied using GIS and applying the HEC-HM model in Shoor-Shirin watershed in Fars...
the devastating impact of land use change in the watershed is increasing the generation rate of sediment and entrance to rivers and sedimentation in reservoirs. according to this, studying on impact of land use change on hydrological process is necessary. aim of this study was investigating the impact of land use change on suspended sediment during 1994 to 2010 by swat model in dinevar watershe...
In order to study the effects of different land uses on soil development, a loess hillslope was selected in Agh-Su area, eastern Golestan Province. Six profiles in four land uses including pasture, Quercuse natural forest, Cupressus artificial forest and a cultivated land, were dug and studied. Samples from different horizons were collected for physico-chemical and microscopic analyses. Importa...
Change in land use and tillage practices has great influence on soil physical and chemical properties. The present study has focused on the effects of converting undisturbed soil to agricultural lands. Chemical and physical soil properties, infiltration, cation exchange capacity (CEC), electrical conductivity, pH, bulk density, porosity, sodium, potassium, total Ca + Mg, organic matter percenta...
The significant objective of this paper is to describe how Cellular Automata (CA) can be used to predict land use land change in the settlement growth and show the advantage of integrating the Neural Network with CA. Cellular automata have been utilized as a prediction technique in the study of an impressively wide range of dynamic phenomena. A spatial simulation model comprises an assortment o...
"Climate dice," describing the chance of unusually warm or cool seasons, have become more and more "loaded" in the past 30 y, coincident with rapid global warming. The distribution of seasonal mean temperature anomalies has shifted toward higher temperatures and the range of anomalies has increased. An important change is the emergence of a category of summertime extremely hot outliers, more th...
extended abstract 1.introduction today the role and the importance of open and green spaces are significantly increasing in the environment and the quality of building complex. therefore, open and green spaces are considered as intrinsic, parts of land use planning decision in most countries. the gardens in the city of jahrom are the indexes of iranian thought and creativity and also the climat...
Keywords: land-use change, land-cover change, determinants of land-use and land-cover change
