Abstract

Land as one of the integral parts of production inputs, not only, plays a critical role in agriculture and natural resource management but also is important part of national economy. LANDUSE CHANGES as a function of environmental and human driving force has caused serious impacts on environment, economy and society over the past decades. Thus, having knowledge on the type of LANDUSE and its CHANGES over the time is one of the main issues for planning and policy making. Current research was conducted to investigate the trend of land use CHANGES in Taleghan throughout remote sensing and GIS. For this purpose, based on multi-temporal data of TM (1987) and ETM+ (2000), land use maps were extracted by digital image classification and maximum likelihood procedure. The extracted maps with the field observation data were imported into GIS and the amount and type of CHANGES were calculated using change detection extension. According to the results the trend of LANDUSE CHANGES in range and ABANDONED LANDS was considerable. ABANDONED LANDS have been increased from 8% to 16%, while rangelands showed the major reduction of 11%. The amount of reduction is very low fpr orchards, agricultural lands and rainfed lands. Due to spectral similarities between abandoned areas and rangelands the necessity of application of more accurate method for land use change detection is needed. On the other hand, because of close relationship between LANDUSE CHANGES and human driving force it can be concluded that such a LANDUSE CHANGES pattern are related to population status that calls for more researches.
