基于GIS的崂山区地下空间利用适宜性评价

为了更好地利用青岛崂山区地下空间资源，在全面分析该区地形、地质、水文等条件的基础上，结合岩土工程勘察原始数据和现场水样调查分析报告，根据模糊数学理论和专家经验，遴选出地形地貌、地质构造、工程地质、水文地质、洪水淹没、人口密集程度为评价因子并确定各因子的权重，研究构建了该区地下空间利用评价模型。将评价模型与GIS相结合，利用ArcGIS强大的空间分析功能，采用定量分析的方法得到地下空间利用适宜性分区。研究表明青岛崂山区地下空间建设适宜区面积为106．1km^2，占评价区域面积的73．8％；一般区域面积为26．5km^2，占评价区域面积的18．4％；不适宜区域面积为11．14km^2，占评价区域面积的7．8％。

Suitability Evaluation of Underground Space Utilization in Laoshan District Using GIS

To make better use of the underground space in Laoshan District, Qingdao, based on an all-round analysis of topography, geology and hydrology, etc, its topography and physiognomy, geological structure, engineering geology, hydrogeology, flood and population density were selected as evaluation factors after incorporating raw datas of investigation of geotechnical engineering and analysis report of water samples on site. The weight of each factor was determined and the evaluation model of underground space exploitation of the distriet was constructed according to fuzzy mathematics and experts experience. The studied underground space in Laoshan District was divided into suitable development area, general development area and unsuitable development area with the evaluation model, GIS, and ArcGIS. The results showed that the suitable development area was 106. 1km^2, as the proportion of 73.8% , the general development area 26. 5 km^2, as the proportion of 18.4%, the unsuitable development area 11. 14 km2, as the proportion of 7.8%.
