中文摘要：
沿海地区由地面沉降问题引起的地质灾害严重影响着城市可持续发展。本文提出了基于天地图面向县级城市地面沉降信息管理方法。首先提出并设计了基于天地图的城市地面沉降信息管理框架;其次,设计了城市地面沉降历史观测数据入库和管理模型,最后,以长江三角洲某县级城市为例,设计并开发实现了县级城市地面沉降信息管理系统,能够实现历史沉降观测信息的在线入库、可视化管理、动态预测和In Sar数据分析等,具有良好的应用前景。
英文摘要：
Geological hazards in coastal district caused by land subsidence have greatly affected urban sustainable development. In this paper,a Tianditu based urban land subsidence information management approach for country-level city is proposed. Firstly,the urban ground subsidence information management framework is presented and designed based on MAPW. Secondly,the data storage and management model of urban land subsidence history observation data is designed.Finally,a county-level city in Yangtze River Delta is taken as an example and a county-level city ground subsidence information management system is devised and implemented. It can achieve online storage,visual management,performance prediction and In Sar analysis on the settlement history observation information,which has promised applications.
