    APPLICATION OF GRAY EVALUATION METHOD IN ENGINEERING CONSTRUCTION SUITABILITY EVALUATION BASED ON GIS AND AHP: A Case Study of the Downtown Huangshan City

    • 摘要: 随着城市现代化进程的加快,工程建设活动日趋频繁.在城市规划、工程建设前进行地质条件分析、适宜性评价是十分必要的.工程建设适宜性受多种因素影响,各因素间相互关联但影响程度不同.文章以黄山市中心城区为实例,从地质环境条件角度出发,介绍基于地理信息系统(GIS)和层次分析法(AHP)的灰色评估法在实际评价工作中的具体应用.该方法首先选取与工程建设适宜性密切相关的影响因素作为评价因子,在对评价单因子定性评价的基础上,用AHP确定各评价单因子的权重,最后用灰色评估法对工程建设适宜性进行综合评估.该应用效果较好,可在同类评价中推广.

       

      Abstract: With the acceleration of urban modernization, engineering activities are becoming increasingly frequent. It is necessary to analyze the geological conditions and evaluate suitability before urban planning and engineering construction. The suitability of engineering construction is affected by multiple interrelated factors in different degrees. Taking the downtown Huangshan City for example, the paper introduces the application of GIS- and AHP-based grey evaluation method in suitability evaluation from the perspective of geoenvironment. The method first selects the influencing factors closely related to the suitability as evaluation factors, then determines the weight by AHP on the basis of the qualitative evaluation on single factor, and finally evaluates the suitability comprehensively with the grey evaluation method. The effect proves to be good, which can be extended to the same kind of evaluations.
