层次分析法在工程建设适宜性评价中的应用——以广州市某镇为例

The analysis of Hierarchy Process(AHP) in Suitability Evaluation of Engineering Construction——A Case Study of a Town in Guangzhou

地质环境是城市规划建设的载体,综合分析各地质环境要素,判定工程建设适宜性,降低城市建设成本与风险,是实现科学化、精细化、品质化城市设计的有效手段。本文以广州市某镇为例,采用层次分析法对研究区的地质环境质量进行量化计算,划分工程建设适宜性亚区,提出针对性的城市用地建议,便于规划设计和决策人员全面认识和把握地质环境容量,为优化城市规划布局提供决策性依据。

Geological environment is the carrier of urban planning and construction,comprehensive analysis of the geological environment elements and determining the suitability of engineering construction are effective ways to reduce the cost and risk of urban construction,as well as to satisfy a scientific,refined and high-quality urban design.Taking a town in Guangzhou for example,an analytic hierarchy process is used to calculate the geological environment quality of the study area,to further divide sub-areas by construction suitability and put forward targeted urban land recommendations,which is energy and time-saving for urban planners and decision-makers to understand and grasp geological environment capacity comprehensively,in order to optimize the layout of urban planning by providing decision-making basis.
