基于多源时空数据的特色村镇保护监测研究与应用

Research and Application of Distinctive Towns and Villages Protection Monitoring Technology Based on Multi-source Spatio-temporal Data

  • 摘要: 在我国全面推进乡村振兴的背景下,健全特色村镇监测评估机制已成为一项重要工作内容。随着多源时空数据的爆发式增长,特色村镇保护监测的数据来源更为丰富,但数据集成能力和信息提取能力仍有待提升。本文利用无人机和中高分辨率卫星遥感数据、现场调查数据、互联网信息,系统地开展了监测方法研究与应用。首先,通过整合不同类型的时空数据,系统构建了2个大类9个小类共38项监测指标,并基于面向对象的随机森林算法,建立了一个多维特征的分类器,实现土地利用分类信息的高精度提取;其次,为解决监测指标的规范化应用和系统集成问题,研发了特色村镇监测软件模块;最后,以浙江省湖州市德清县莫干山镇何村村为例,开展特色村镇保护监测应用示范。

     

    Abstract: Under the background of comprehensively promoting rural revitalization, it has become an important task to improve the monitoring and evaluation mechanism of distinctive towns and villages. With the explosive growth of multi-source and spatio-temporal data, the data of protection monitoring in distinctive towns and villages are more abundant, but their integration ability and information extraction ability still need to be improved. In this paper, the data consisting of unmanned aerial vehicle (UAV), medium and high-resolution satellite, field investigation data, and Internet information are systematically used in the research and application of monitoring methods. Firstly, by integrating different types of spatio-temporal data, the monitoring indicators including 38 monitoring indicators enlisted in 2 categories 9 subcategories are constructed, and in this system, a multi-dimensional feature classifier is established based on object-oriented random forest algorithm to achieve the high-precision extraction of land use classification information. Then, the B/S architecture-based monitoring module is designed for a standardized application and system integration. Finally, a case study at Hecun Village, Moganshan Town, Deqing County, Huzhou City, Zhejiang Province is taken as an example for the demonstration of this protection monitoring system.
