摘要
利用GIS的空间数据管理和分析功能,在GIS平台上对东营市中心城区浅层地下空间资源进行了评估。首先就东营市区的工程地质特征和城市地下空间资源开发及需求状况进行了调查和分析,在此基础上系统地研究了影响东营市地下空间资源质量主要因素,建立东营市地下空间资源评价指标体系,并给出了相应指标值,在GIS平台上运用所建数学模型对东营市地下空间资源质量进行了综合评估,划分出不同质量等级的地下空间单元。初步将其浅层地下空间资源质量划分为3个等级和1个特殊区,其所占地下空间资源总量分别为79.2%、8.8%、8.5%、3.5%。
Using the features of data management and analysis of GIS,this paper carries out the evaluation of shallow underground space resource in Dongying City.First of all,a systematic research is made on the engineering geological characteristics.The demand and situation of the exploitation of underground space resources are researched.On these bases,the influencing factors are analyzed for the underground space resource in Dongying City.An evaluation index system is made.Every index is calculated.By combining GIS with established mathematical model,a comprehensive evaluation of underground space resource in Dongying City is done.As a result,the survey region can be preliminarily divided into three levels and one independent zone,respectively. They make up 79.2%、8.8%、8.5%、3.5%of the overall area.
