Abstract

Land use type has been an important part of human societies. As it gradually develops, and the human society demands change, the necessity of changing the land use is becoming more obvious.The objective of this study was to determine the qualitative LAND CAPABILITY of Mashhad sheet map based on multipurpose land classification- FAO & Data Bank Softwares of Land Evaluation (DBSLE). Method of simple limitation was used for qualitative evaluation of both methods with scale of 1:250000. In this study, physical and chemical factors which affect the LAND CAPABILITY were evaluated without considering the crop yield and socis-economic factors. The location of evaluated area is between 37o -38o E latitude, and 57o -58.5o N longitude with an area of 1472205 ha. Based on FAO method, LAND MAPPING UNITs were formed according to physiographic types, limitations and available facilities. Then using DBSLE method, three maps of physiographic type, slope and sensitivity of rocks to weathering (geology) were combined by using GIS software, to produce LAND MAPPING UNITs. Capability map for both methods was prepared based on field observation and profile description. The results of this study showed that all the capabilities of physiographic types for both methods were similar, but the capability of hills, plateaus, flood plains and complex lands were different. According to FAO methods, hill, plateau & complex lands were suitable for pasture, but the results of DBSLE methods showed that hills and complex lands were appropriate for irrigation and plateaus were suitable for orchards. With regard to land characteristic, it was found that FAO method has a better evaluation.The results of FAO method showed, flood plains were suitable for pasture, but they were also good for irrigation based on DBSLE method. Unfortunately, chemical factors have not been considered in DBSLE method. Therefore, the results of this method for flood plains were not reliable.Finally, based on these results it was suggested that determination of capability in hills, plateaus and complex lands by DBSLE method must be revised, and for flood plains, important soil chemical factors should be considered.
