Locating garden burial centers in Khodaafrin and Kalibar cities based on Boolean logic model and ANP network analysis in GIS environment
Abstract
Introduction: The lack of proper management and the lack of choosing the right place for disposal and burial of waste creates problems for the human and animal environment. Khoda Afarin city has a population of about 34977 people and Kalibar city has a population of about 48837 people. In the last few decades in these cities, with the increase in population, consumerism, and the change in people's eating habits, the increase in the consumption of packaged materials along with the imitation of people's consumption pattern has caused an increase in the production of a large amount of waste. Despite this problem, there is still no proper way to dispose of waste in these cities. The purpose of this research was to locate landfill centers based on ANP network analysis process model and Boolean logic in GIS environment by using the opinions of expert experts in the form of pairwise comparison questionnaires and descriptive-analytical method.Material and methods: In this research, in order to select landfill centers due to the complexity of the influencing factors, the necessity of using geographic information technologies (GIS) and its integration with other management and planning matters has been proposed; Therefore, in this research, ARC GIS software has been used to create databases, spatial analysis and superimposition of information layers, as well as ANP model and Super Decision software to calculate criteria weight and Boolean logic model.Results and discussion: In this research, 17 layers of information include; Surface water resources, slope, city and village areas, protected areas, fault, soil, road network, litology, land use, erosion, NDVI, dem, climate, land side, dam, aspect Then, in the network analysis process model, Super Decision software was used to apply weights for each of the criteria, and in the ArcGIS environment, the information layers were combined with the final weight, and the value of each cell was determined in the final map. The area of 369221 hectares was divided into four categories: unsuitable 174720 hectares, relatively unsuitable 146677 hectares, suitable 42670 hectares and completely suitable 5154 hectares in terms of landfill location, and in Bolin logic, the estimated area of unsuitable 365457 hectares and suitable 3938 hectares for landfill location Garbage detected. Finally, due to the closeness of the areas to each other, the final maps of both models were overlapped, and after merging the locations of 2679 hectares, a suitable location was determined, which covers 73 percent of the suitable areas of the Boleyn model.Conclusion: The comparative analysis of the results shows that finally, in the ANP model, only 1.4 percent of the area of the area is completely suitable, and in the Boleyn model, 1.2 percent of the area of the area has optimal conditions for the landfill. One of the most important achievements from the results of this research is the use of a completely suitable place and the final result of the map from this research.
