تعیین موقعیت بهینه دفن پسماندها در استان زنجان

   In the recent years there has been attention on the management of dangerous wastes because of their incremental growth, since ignorance toward this problem will result in numerous environmental, social and economical problems. Finding an optimized place for the urban and rural waste burial, with least environmental danger and economical optimality is one of the main objectives of this paper. In the presented study, the research method and the type of practical research is description-analysis and for data gathering, we used the library and athletic studies. The data analysis has been done by a scoring method (5-0) and the web analysis method which is a multi-objective decision-making method. Since in the ANP method the qualitative and quantitative factors and the correlation of the factors have been taken into account, we used social, economical and environmental factors for evaluation of the waste burial centers and their impacts on the towns and villages of the Zanjan province. The process of evaluation of the optimal waste burial centers is done in some stages including preparation of distance maps, prioritizing from the importance point of view using the geographical information system technologies (GIS), determination of the weights and at last, merging the resulted maps using the ANP method. The research results show that the prioritized regions in the map are based on the waste burial places. Based on this method, the 5th priority in the maps and especially in the final map shows the most suitable place and the 1th priority shows the least value and the 0 priority has no value for the waste burial places.
