在大数据背景下，针对动态遥感监测研究领域面临的数据处理方法相对落后、国土数据资源存储规模大且管理复杂、监测图斑数量庞大、数据安全保障等问题，设计并实现了一种面向国土数据资源的动态遥感监测原型系统，结合项目组前期“数字国土平台”、“面向数据的架构”、“分布式计算框架”等研究成果，对原型系统在数据注册中心、数据存储、数据处理、数据服务以及数据安全等五方面进行研究。测试结果表明，该系统能够在顾及数据全生命周期内的安全性同时，实现对监测区域的变化信息自动提取和图斑类型自动判识，为进一步数字国土建设、土地利用变更调查等研究提供了技术支持。

To solve the new problems (outdated Dynamic Remote Sensing Monitoring data processing,complicated management of the land data resources requiring large capacity storage,enormous number of monitoring map spots,data security and etc) appearing with the rising of big data,we designed and implemented a prototype of dynamic remote sensing monitoring for land data resources.Based on the prior research achievement of the project team,like digital land platform,data oriented architec-ture,distributed computing framework,the research on five aspects of prototype system (data registry center,data storage, data processing,data services and data safety)was completed.The test results prove that the system can automatically extracts varied information in the monitor area and automatically detects the types of map spots while simultaneously ensures the safety of the whole data lifecycle,and provides technical support for further construction of the digital land,the land use change sur-vey and etc.
