郑州市地下空间资源开发利用地质适宜性评价

地下空间资源作为郑州市一种尚未大规模开发的城市建设载体,已成为城市发展的宝贵资源。在系统分析了郑州市地质条件的基础上,研究了该地区地下空间资源与地质环境之间的相互关系,从而建立了基于地下空间开发利用的适宜性评价指标体系,并采用层次分析法确定指标权重,运用敏感因子—综合指数评价模型对该地区的地下空间资源开发利用适宜性进行了评价。评价结果表明,郑州市各层地下空间资源开发利用适宜区及较适宜区占研究区面积的一半左右,总体情况较好。

Geo-environmental Suitability Assessment of Underground Space Resources Exploitation and Utilization in Zhengzhou City

The underground space resources of Zhengzhou city have not been a carrier yet in the large-scale development of the urban construction and become the precious resources for the urban development. In this paper, based on the system analysis on the geological conditions in Zhengzhou city, the relationship between the underground space resources in this region and the geological environment had been examined. The appropriate suitability assessment index system for the underground space resources exploitation and utilization was established. The weights of indexes were determined using the Analytic Hierarchy Process (AHP) and the sensitive factor-integrated index model was used to evaluate the suitability of underground space resources exploitation and utilization in this region. The results show that the suitable and less suitable areas for each layer of underground space account for approximately 50% of the total area in Zhengzhou city.
