城市地下空间资源地质环境适宜性评价方法对比分析

为了选择最优的地下空间资源地质适宜性评价模型，对地下空间进行资源科学、合理的评价，给地下空间开发提供合理的规划支持，笔者等选取了3种不同的模型，对其进行对比分析，总结其优缺点及适用条件，并以深圳市南山区为例进行地下空间资源地质适宜性评价，利用 ArcGIS生成了南山区地下空间资源地质适宜性评价分区图。评价结果表明，最不利等级判别法评价模型较为适用于南山区的地质适宜性评价，突出了敏感因子对于南山区地下空间开发的制约性作用。笔者等的研究对未来地下空间资源地质适宜性评价的模型选择具有一定借鉴意义，为深圳市南山区的地下空间规划提供一定的参考。

Comparative analysis of geological environment suitability evaluation methods for urban underground space resources

In order to select the optimal geological suitability evaluation model of underground space resources, realize scientific and reasonable evaluation of underground space resources, and provide reasonable planning support for underground space development. In this paper, three different models are selected for comparative analysis, and their advantages, disadvantages and applicable conditions are summarized, and the geological suitability evaluation of underground space resources is evaluated by taking Nanshan District of Shenzhen as an example, and the zoning map of geological suitability evaluation of underground space resources in Nanshan District is generated by ArcGIS. The evaluation results show that the evaluation model of the most unfavorable grade discrimination method is more suitable for the geological suitability evaluation of Nanshan District, highlighting the restrictive effect of sensitive factors on the development of underground space in Nanshan District. This paper has a certain reference significance for the future model selection of geological suitability evaluation of underground space resources, and provides a certain reference for the planning of underground space in Nanshan District, Shenzhen City.
