摘　　要：针对空间数据库教学中存在的学科背景弱、系统性低、理论知识与实验设计脱节、实践平台成本高、与课程衔接差、传统内容与新技术脱节等问题,本文提出科研-教学-应用新型空间数据库课程体系。在理论部分,引入并加强空间数据模型、空间索引、空间直方图和空间查询优化等内容,配合相关课程形成课程链,丰富学生理论知识,引入区块链等前沿技术以开拓视野和创新思维。在实践部分,构建跨领域、多尺度、具有地理特色的系列实验案例和基于开源软件的实践平台,强化学生专业理解力、实验沉浸感和学科归属感,同时降低实践成本和门槛。本文研究成果能够为国内空间数据库教学提供有益参考。Aiming at solving the problems of weak disciplinary background,low systematicity of curriculum content,disconnection between theoretical knowledge and experimental design,high cost of the practice platform,poor connection with curriculum,and disconnection of basic theory and the rapid-developing emerging technologies,this paper proposes a new spatial database curriculum system of research-teaching-application.In terms of theoretical knowledge,spatial data model,spatial index,spatial histogram and spatial query optimization are introduced and strengthened to form a curriculum chain to enrich students’ basic theoretical knowledge of the discipline.And the introduction of blockchain and other cutting-edge technologies develop students’ vision and innovative thinking.In terms of practical cases,a series of experimental cases with cross-disciplinary,multi-scale,and geographic characteristics and a practical platform based on open source software are constructed to strengthen students’ professional comprehension,experimental immersion,and sense of belonging to the discipline,as well as to reduce the cost and threshold of practice.This study can provide a useful reference for teaching spatial databases in China.
