Analyze the unique advantages of UAV remote sensing technology and discuss the feasibility of using UAV remote sensing for rapid detailed investigation of land -use.Study on the UAV remote sensing data and then expound the data processing technology . Summarize the work process of rapid detailed investigation of land -use based on the UAV remote sensing and GIS technology and fo-cus on the land information extraction , analyze the advantage of the classification method of object -oriented remote sensing image . According to the requirement of rapid detailed investigation of land -use, the building of the land-use database is analyzed deeply . This paper describe database storage structure , spatio-temporal data model and the feedback of land -use detailed investigation , which avoids the data redundancy issues and increase the proportion of valid information in the database .%分析了新型无人机遥感技术相对于传统遥感的先进性，并结合土地快速详查的任务需求，表明利用无人机遥感进行土地利用快速详查是可行的。根据无人机遥感数据的特征详细阐述了图像的后处理技术，提出了基于无人机遥感和地理信息系统（ GIS）技术的土地利用快速详查工作流程，重点研究了土地信息的提取，并分析了面向对象的遥感影像分类方法的优点。针对土地利用快速详查的要求，对土地利用数据库的构建做了深入分析，详细阐述了数据库的存储结构、时空数据模型和土地利用详查追溯三个方面，很大程度上避免了数据冗余问题，提高了数据库中有效信息的比重。研究成果可为新时期国土资源管理工作提供有益参考和借鉴。
