基于熵权-层次分析法的地下空间适宜性评价

较为客观地评价城市地下空间开发适宜性,是科学合理有效利用城市地下空间的前提和依据。提出熵权-层次分析法以实现权重的客观分析计算,综合考虑影响城市地下空间开发的主要地质因素,采用层次分析法建立评价指标体系,运用模糊综合评判法评价地下空间开发适宜性,并使用ArcGIS生成地下空间开发适宜性分区图。评价结果表明,郑州市地下空间开发非常适宜区占研究区面积的22.64%,适宜区占34.41%,一般适宜区占35.90%,不适宜区占7.05%。该评价结果较为客观、合理,可以为郑州市地下空间开发整体规划提供参考。

Evaluation Suitability for Underground Space Using Entropy Weight-analytic Hierarchy Process

Objectively?evaluating?the?suitability?of?urban?underground?space?development is the premise and basis for scientific, rational and effective utilization of urban underground space. Entropy weight-analytic hierarchy process is proposed to achieve objective analysis and calculation of weights in this paper. The main geological factors affecting the development of urban underground space are considered comprehensively. The evaluation index system is established by the analytic hierarchy process, the suitability of underground space development is evaluated by the fuzzy comprehensive evaluation method, and the suitability zoning map of underground space development is generated by ArcGIS. Evaluation results show that most suitable area for underground space development is 22.64% of the total area, the suitable area is 63.07%, the generally suitable areas is 31.69%, and the unsuitable area is 63.07%. It is objective and reasonable to provide reference for the overall planning of underground space development in Zhengzhou.
