Abstract
Rangelands are one of the most vulnerable resources in Iran which have been invaded in various ways since the nationalization. Land reform law and its enacting clauses are among the main reasons for condescension of the national lands. The purpose of this study is to investigate the land use changes based on documents available in the records of implementation of natural resource regulations, land affairs, the situation at that time and the current situation. This research is of quantitative and practical type and its statistical population consisted of six registration plaques of Bileh Savar city of Ardabil province. Possibility of access to the registration files of these plaques and their proximity to each other were the reasons for choosing this area. After receiving the information, the maps were investigated in the Arc GIS environment. The overlap extent of all maps was examined using the Kappa coefficient in Idrisi Selva environment. Using aerial photographs of 1962 as well as the current situation using Google Earth satellite images (2015), all areas of national lands and exceptions in different periods were compared. To perform this comparison, a pair T test was applied. The results showed that there was a significant difference between the area of national lands and exceptions at the time of implementing natural resource regulations and aerial photographs of the same period. While the land affairs documents at the same period did not have significant difference from aerial photographs. In addition, the implementation of various land assignment laws until 2015 has led to the assignment of more than 90% of national lands in this region. At the time of the nationalization of the rangelands, by plowing most of the national lands, the beneficiaries were trying to change the national lands to agricultural lands. Recognition of the waste land and formerly-utilized land was another reason for difference in statistics of these two offices. It is proposed to protect the national lands by fully implementing the cadaster system and adopting laws against land grabbers.
