基于熵权TOPSIS分析法的郑州市三维地质环境承载力评价

Evaluation of Zhengzhou city 3D geological environment carrying capacity based on entropy weight TOPSIS analysis

城市地上地下一体化开发利用成为当代城市发展的必然趋势,城市三维地质环境承载能力是城市整体规划不可或缺的组成部分。本文以郑州市为例,运用工程地质、水文地质、地下空间开发现状、地表生态交通环境等数据对郑州市地质环境进行三维建模,继而选取相应指标,运用熵权TOPSIS方法,对郑州市地质环境承载力进行评价。结果表明,郑州市已开发区域承载能力最弱,北部沿河区域承载能力较弱,城市中部承载能力适中,南部承载能力较强,为郑州市地下空间开发提供了参考。

The integrated development of urban areas above and below ground is becoming an inevitable trend in contemporary urban development.The carrying capacity of the 3D geological environment of the city is an indispensable component of urban master planning.This article uses Zhengzhou city as an example and utilizes data such as engineering geology,hydrogeology,the current status of underground space development,and surface ecological and transportation environments to create a 3D model of Zhengzhou city s geological environment.Subsequently,relevant indicators are selected,and the entropy-weighted TOPSIS method is used to evaluate Zhengzhou city s geological environment carrying capacity.The results indicate that the carrying capacity of the developed areas in Zhengzhou city is the weakest,the carrying capacity in the northern riverside areas is relatively weak,the central urban areas have a moderate carrying capacity,and the southern areas have relatively strong carrying capacity,providing a reference for the development of underground spaces in Zhengzhou city.
