evaluation and monitoring of agricultural land use changes geographic information system (case study: dastjerdi village- tarom county)

extended abstract 1. introduction land as habitat and place of having the highest importance in human life and the source of all human needs is. any planning requires having information about the phenomena on the land, trappings and paraphernalia land. this information collected is an issue that eventually will lead to the management of land information in one system. organization and operation of information and access to it will be a need for a comprehensive and integrated land information system known in the world, respectively. arable land in the world during the time of political powers and peasant revolution changes that lead to an increase in some of them the size of farm units and in some reduction in the distribution of lands and been, so do land reform in developing countries caused by big owners of lands that culture group myshdnd to farmers who lost occupied and then taking possession of land to sell and transfer the action. this disseminate the agricultural lands of farmers in several parts of the village is. 2. theoretical framework subject of studies land use, how various phenomena and methods of exploitation of its land. land use change is one of the drivers of environmental change at the global level for numerous and therefore sustainable development should be considered. the traditional analysis of land use and understand the process and the preferred approach, the decision notified to advanced civilian applications, probable and gives support to environmental objectives in the future. agriculture, land identified on the basis of segmentation, identification of agricultural territory, dry land and irrigated crops and pasture for the by responsible organizations such as the organization of agriculture and water, the real estate registration and department of natural resources conducted in the province. maps could be the comprehensive information provided on the property and the type of agricultural products that could be in economic planning and identification of resources survey carried out revealed that the years-in (1990-1929) real estate registration law is established on 95% of the territory, which means it is an open list of the phosphating land in macedonia fhrsthay plasticizers use is made of land use and the remaining 5% there is no recorded data. 3. methodology in this research to develop cadastral maps years studied (1998-2011) aerial photographs of 1: 10,000 of the area and after the conversion and digitizing aerial photographs to map ground operation in order to remove the attribute information related to cadastral maps were. ground for the cadastral maps were finally in gis data base (gis) was created. and analysis of existing maps, in medias, auto deskmap, arc gis, idrisi, took place. for quantitative data analysis of software hay like excell, spss and to assess any changes occur, such as changes in the statistical method of evaluation methods used crosstab. 4. discussion the analyzes conducted on cadastral maps of the study area show. the total number of piece parts from 1304 in 1998 to 1658 in 2011 increased by piece the highest number of land parcels in both periods was related to agriculture and the minimum number of pieces of land use is made. were related to agriculture from 18/79 percent to 47/61 percent of the land in 1998 that the change was in 2011, a downward trend during the period according to the view of the study carried out shows that another user had an increasing trend during this period. the increase land use made to other uses that the main reason for its higher-buying and selling of land by investors in the region with the purchase of high-cost rural lands increases the number of factories; industries have been in the area. surveys showed that the decline in the study area mainly due to the conversion of agricultural land use users such as factories made clear the grass, pasta, flour, and livestock industry, etc. there is the main reason these changes are more raw materials to industries and high potential to produce like grapes, it is an agricultural land of the village that creates added value in the sale and export of raisins to other countries in the region is. increase there in the number of components in the study area showed that the dam construction and water shortages channeling agriculture among farmers and gardeners somewhat reduced and increased the price of land in the region and to that is why some farmers of their lands divided into smaller pieces and sold to another person. 5. conclusion according to the results of 1304 the total number of piece parts in 1998 to 1658, the highest number of land parcels segment in 2011 increased in both periods related to agriculture and the lowest number of pieces of land due moderate and severe asthma made its main change is to reduce the problem of water shortage caused by farmers and gardeners and duct-concrete dam between agriculture and an increase in speculative land area respectively. comparing the land use map by cross tab in the region during the period (1998-2011) approximately 04.21% of the total land (614/216 hectares) during the period studied, repurposed with a 76/23% of the parts (394 pieces) contain the most variation tremblay in the area of communication has occurred. the survey conducted showed that the highest use changes related to changes in agricultural land use vineyard lots that 9.9% of the total area land (3/98 hectare) and 171 pieces of parts account that these changes primarily related to a decrease in dam construction and irrigation water shortages by land area and second by concrete and water to be channeled land area by concrete and this harvest and increase product processing industries in the region, respectively.
