Estimation of Vegetation and Land Use Changes Using Remote Sensing Techniques and Geographical Information System (Case Study: Roodab Plain, Sabzevar City)
Land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. So far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. This paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...
متن کاملAssessment of mountainous ecosystems in Central Asia by using remote sensing based vegetation cover fractions
Mountainous regions are especially vulnerable to climate and land use change. For a monitoring of subtle changes detailed and continuous land cover information is necessary. Therefore vegetation cover fractions are derived for the Naryn river catchment in Kyrgyzstan using a remote sensing multi-scale approach. First a very high resolution QuickBird image is classified into discrete classes usin...
متن کاملQuantifying the trend of vegetation changes using remote sensing (Case study: Fars Province)
Investigating the sustainability of vegetation changes is one of the most important issues of vegetation management in the direction of sustainable development. It is necessary to conduct studies in this regard to select appropriate management for greater compatibility with new conditions. In this research, changes in the vegetation dynamics trend of Fars province were studied using the NDVI in...

15 صفحه اولApplication of Remote Sensing in Assessing Land Use Changes in Haraz Watershed
Aims: Land-use change due to human activities is one of the important issues in regional and development planning. The aim of this study was to detect land-use changes using Landsat TM, ETM+, IRS and ASTER satellite imagery. Methodology: In this quasi-experimental study, land-use changes in the Haraz watershed over a 23-year period were evaluated. For this study, images of 1992 TM, ETM + 2002, ...
