ABSTRACTPopulation increase and its impact on natural ecosystem may lead to land use change and destruction of nature Consequently evaluation of the land use changes gives us an opportunity to plan and to manage the lands in order to reduce the destruction effects of the exploitation of the lands Hence detection and evaluation of the changes can be performed by remote sensing and geographical information system GIS with the least cost and time Satellite images with their high spectral and spatial resolution as well as having various image processing techniques are able to estimate the lands use changes and to manage them This study was an attempt to evaluate the percentage of the grounds coverage and the land use changes in Qazvin plain during the period of 1987 to 2002 For this purpose the map of Qazvin plains land use during 1987 to 2002 years with the supervised classification method and algorithm of maximum similarity likelihood was provided by using TM and ETM satellite images and geometric atmospheric error correction as well as choosing the best combination band The accuracy of the map was computed by utilizing overall accuracy test and Kappa statistic The result indicated that the rate of variability of the orchard increased from 16 to 21 percent irrigated cultivation increased from 17 to 27 percent and the salt marsh increased from 24 to 26 percent On the other hand two decreases from 19 to 9 percent and 24 to 15 percent were reported for dry and arid lands respectively According to the obtained results it can be concluded that the dominant trend of the land use change has been positive in the period The produced maps were investigated by control points in the field and previous studies in order to evaluate the accuracy of the classification results The Kappa coefficient of the maps from ETM and TM images was calculated 80 and 77 percent respectively Keywords land use land use change
