Feasibility Study of Olive Cultivation in Fars Province by Applying Weight Ranking Models of GIS

Abstract

Nowadays, the problem caused by human’s incorrect usage of productive lands has led to researchers and experts’ great attention to land preparation and ecological models. In order to do so, they need to measure ecological resources of the earth by proper methods. This project intends to identify the effective ecological factors and elements in planting olive in Fars province, Iran. Also, it intends to zone the productive lands for planting olive based on ecological and environmental factors; to achieve this aim, geographical information system in combining different information levels is being used, also they are arranged in different models. In this research, through some studies on province ecological status, then comparing them with ecological olive prerequisite, an ecological and environmental data base of the province is provided based on Arc GIS software. Then it tries to clarify the resulted maps based on olive planting capability; it should be mentioned that this clarification is done based on the relationship between any of the effective environmental and ecological parameters in planting olive and function of olive products. Afterward it determines the values, the weight models (rank sum, reverse ranking, exponential ranking). Indeed, the achieved maps are mixed together in the context of Arc GIS. Then based on achieved results from the maps, 14 percent of the province area in average are considered proper to be planted with the olive. These special areas are mostly located in the middle part of the province.
