Vulnerability of soil separates to detachment by water is described as soil erodibility by Universal Soil Loss Equation which can be affected by land use change. In this study it was attempted to quantify the changes of Universal Soil Loss Equation K-factor and its soil driving factors in three land uses including rangeland, rainfed farming, and orchards in Babolrood watershed, northern Iran. S...

The impacts of land utilization change on the ecosystem service values in Daqing during 1995 to 2015 were analyzed based on unit area ecosystem service value of Chinese territorial ecosystem from Mr. Xie Gaodi and ecosystem service value calculation formula from Costanza. Results showed that the ecosystem service value of Daqing decreased from US $4343.1559m in 1995 to US $3824.327m in 2015, wi...

landsat data for 1992, 2000, and 2013 land use changes for ekbatan dam watershed was simulated through ca-markov” model. two classification methods were initially used, viz. the maximum likelihood (mal) and support vector machine (svm). although both methods showed high overall accuracy and kappa coefficient, visually mal failed in separating land uses, particularly built up and dry lands.there...

the concept of land use transition highlights that land use change is non-linear and is associated with other societal and biophysical system changes. changes in human systems has resulted in changes in the natural system such as changes in land use. land use change causes not only environmental factors like geography and topography are important, but social factors examined such as population ...

This paper describes a tool prototype named as Land Use Change Explorer, which was developed to allow different users to generate "GKD process tracking” (discovering land use change patterns) and “GKD process steering" (understanding uncertainty in these patterns as the process unfolds). The Land Use Change Explorer was implemented based on the GeoInsignt approach, previously described in Wacho...
