耕地变化智能检测系统设计与实现

Design and Implementation of Intelligent Detection System for Cultivated Land Change

随着城镇化的快速发展,大量耕地被占用为建设用地。利用遥感手段进行耕地变化检测具有宏观性和便捷性,同时现有的土地利用矢量数据能够提供先验知识信息,故研究基于基期土地利用矢量数据和新时期遥感影像数据的耕地变化自动检测方法,构建耕地变化解译知识库,通过知识驱动实现耕地变化的自动检测,具有重要的现实意义。

With the rapid development of urbanization,a large number of cultivated land is occupied as construction land.Using remote sensing to detect cultivated land change is macroscopic and convenient,and the existing vector data of land use can provide prior knowledge information.Therefore,it is of great practical significance to study the automatic detection method of cultivated land change based on the vector data of land use in the base period and remote sensing image data in the new period,build the knowledge base of cultivated land change interpretation,and realize the automatic detection of cultivated land change through knowledge driving.
