Abstract

The problem of environmental degradation and pollution resulting from quarry operations is becoming a critical problem. Therefore, the selection of optimal quarry sites is a prerequisite for safe operation and economic viability. The present study was carried out around Harer and Dire-Dawa towns to identify the optimal location of quarry sites by using an integrated AHP and GIS approaches. The selection was carried out by considering environmental and socio-economic factors. For each of the factors, appropriate classifications and criteria were formulated. Finally, a weighted overlay analysis was applied to produce the preliminary quarry site suitability map. About 136 km2 of the area is highly suitable, 1,587 km2 is moderately suitable, and 2,166 km2 has low suitability for quarry site. The approach followed by the study helped to narrow the area to the suitable sites that may further be studied through detailed field investigation. Hence, it can be adopted elsewhere as a guide for economical quarry site selection.

基于GIS-AHP的埃塞俄比亚东部哈雷和迪雷达瓦镇采石场选址优化方法

采石场作业造成的环境退化和污染问题正在成为一个严重的问题。因此，选择最佳采石场是安全运行和经济可行性的先决条件。本研究在Harer和dre - dawa镇周围进行，利用综合层次分析法和地理信息系统方法确定采石场的最佳位置。选择是在考虑环境和社会经济因素的基础上进行的。对于每一个因素，都制定了适当的分类和标准。最后，应用加权叠加分析得到了初步的采石场适宜性图。高适宜采石场面积约136平方公里，中等适宜采石场面积约1587平方公里，低适宜采石场面积约2166平方公里。这项研究采用的方法有助于将研究范围缩小到合适的地点，这些地点可以通过详细的实地调查进一步研究。因此，它可以作为经济采石场选址的指导。
