摘要
地下空间开发是城市建设快速发展的重要途径,而地下空间开发适宜性评价是城市地下空间资源开发利用的首要工作。滨海城市相对于内陆城市环境更为复杂,影响地下空间开发的因素也更为丰富。以山东省潍坊市北部沿海平原浅层(0~20 m)作为研究区,充分调查分析影响地下空间开发的指标因子,构建滨海城市地下空间开发适宜性评价指标体系,采用改进的结构CRITIC主客观相结合的赋权方法进行指标确权,同时,基于ArcGIS地理信息系统进行综合评价及结果可视化处理。结果表明:(1)提出的改进的结构CRITIC赋权方法既增加了客观性又保留了重要因子权重,相较于传统单一的赋权方法,主客观相结合的组合赋权更为科学;(2)断裂构造、地下水富水性、水位埋深在指标体系中占据重要地位,权重分别是19.4%、12.2%和11.3%;(3)研究区地下空间开发非常适宜面积占比12.6%,较适宜区域占31.84%,一般适宜地区占31.03%,较不适宜地区占18.93%,最不适宜占5.59%。
The underground space development is an important way for the rapid development of urban construction,and the suitability evaluation of underground space development is the primary work for the development and utilization of urban underground space resources.Coastal cities are more complex than inland cities,and the factors affecting the underground space development are also quite abundant.Taking the shallow layer(0~20 m)of the northern plain of Weifang City,Shandong Province as the research area,the index factors affecting the underground space development are fully investigated and analyzed,and a combining subjective and objective weighting method of the improved the structural CRITIC is used to determine the weight of the index.At the same time,the results of the suitability of underground space development in the study area were also visualized by weighting the sum of evaluation factors based on ArcGIS.The results show that:(1)The proposed improved the structural CRITIC weighting method not only increases the objectivity but also retains the weight of important factors.Compared with the traditional single weighting method,the combining subjective and objective weighting method is more scientific.(2)Fault structure,groundwater abundance and water level depth occupy an important position in the index,and the weights are 19.4%,12.2%and 11.3%respectively.(3)The percentage of area in the very suitable part is 12.6%,the more suitable area is 31.84%,the generally suitable area is 31.03%,the less suitable area is 18.93%,and the least suitable area is 5.59%.
