快速的城市化和物质发展在Bonab产生了大量的建筑和拆除废物,伊朗西北部的一个城市。为了达到较高的准确性和最大限度地减少主观偏差,在地理信息系统(GIS)环境中结合了突变理论(CT)原理,以确定安全处置废物的合适位置。Bonab市建筑垃圾填埋场(CWLF)的选址过程包括准备和整合12张代表海拔的地图,斜坡,地质学,土壤类型,土地利用,植被,距离人口中心,宝贵的生态系统,河,地下水并使用CT进入主要道路,以减少与主观评估相关的不确定性。对变量相对重要性的评估表明,海拔,斜坡,与城市的距离,植被覆盖,和通信网络的距离在建筑垃圾填埋场的选址中具有更大的重要性。相反,距离河流,地下水位,距离村庄,有价值的生态系统影响最小。在城市北部和西部的部分地区确定了合适的区域。确定的地点有一个平缓的斜坡,农业潜力低,良好的通信网络接入,到城市的距离合适,对地下水位没有限制,地质构造,和植被覆盖。
Rapid urbanization and physical development have produced a significant quantity of construction and demolition waste in Bonab, a city in northwest Iran. In order to achieve a high level of accuracy and minimize subjective bias, catastrophe theory (CT) principles were combined in the geographic information system (GIS) environment for identifying suitable locations for safe disposal of the waste. Site selection process for construction waste landfill (CWLF) in Bonab city involved preparation and integration of 12 maps representing elevation, slope, geology, soil type, land use, vegetation, distance to population centers, valuable ecosystems, river, groundwater, and access to the main roadways with the CT to reduce uncertainty associated with subjective evaluations. Evaluation of relative importance of the variables showed that elevation, slope, distance to the city, vegetation cover, and distance to communication networks have greater importance in site selection for construction waste landfill. On the contrary, distance to the river, groundwater level, distance to villages, and valuable ecosystems have the least impact. Suitable areas were identified in parts of the north and west of the city. The identified sites have a gentle slope, low agricultural potential, good access to the communication networks, suitable distance to the city, and no limitations regarding the groundwater level, geological formations, and vegetation cover.
