摘要
对城市地下空间资源进行科学、合理的评价,是有效利用地下空间资源、编制地下空间规划的重要依据。基于影响地下空间资源开发利用的地质条件,分别构建了普通因子和敏感因子的地下空间资源地质适宜性评价体系,并对指标体系加以量化,采用熵权法计算指标权重,并利用AHP对熵权法进行优化。在此基础上,利用多目标线性加权函数法和最不利等级判别法进行地下空间地质适宜性评价,并以广东深圳市南山区为例开展地下空间资源评价。评价结果表明,深圳市南山区地下空间资源适宜性好的区域占47.81%,适宜性一般的区域占43.63%,适宜性差的区域仅占1.92%,禁建区占3.30%。该评价结果可为深圳市南山区的地下空间规划提供参考,评价模型和权重确定方法对未来地下空间资源地质适宜性评价具有一定借鉴意义。
Scientific and reasonable evaluation of urban underground space resources is an important basis for effectively utilizing underground space resources and preparing underground space planning.Based on the geological conditions of the development and utilization of underground space resources,this paper constructs an evaluation system of geological suitability of underground space resources based on conventional factors and sensitive factors,quantifies the index system,uses the entropy weight method to quantify the index weight,and uses AHP to optimize the entropy weight method.On this basis,the multi-objective linear weighting function method and the most unfavorable grade discrimination method are used to evaluate the geological suitability of underground space,and the Nanshan District of Shenzhen is taken as an example to evaluate the underground space resources.The evaluation results show that 47.81%of the areas with good suitability of underground space resources in Nanshan District of Shenzhen,43.63%of areas with general suitability,only1.92%of areas with poor suitability,and 3.30%of areas with prohibited construction.The evaluation results can provide some reference for the underground space planning in Nanshan District,Shenzhen.The evaluation model and weight determination method in this paper have certain reference significance for the geological suitability evaluation of underground space resources in the future.
