目前，全国范围内开展了第二次土地利用更新调查，在应用传统技术方法的基础上，随着遥感、航测、RS、GPS、GIS等新技术的发展应用，土地利用现状更新调查技术、方法得到了显著的改进,出现了很多新的技术路线和方法。调查技术和方法的全面多样、高效实用，提高了土地利用现状更新调查成果与实际状况的符合性和正确性。这些使我国土地利用更新调查进入了一个新的技术阶段。但土地利用更新调查作为一项基础性的调查工作，技术难度高、涉及面广，仍有许多关键技术问题需要突破。今后，应该进一步加强新方法的研究，拓宽研究思路，实现多种方法综合应用，实行土地利用动态监测使国家实时掌握土地利用变化的变化情况Currently, the country launched its second update of land use survey methods in the use of traditional technologies on the basis, along with remote sensing, aerial survey, RS, GPS and GIS technologies, such as the development of new applications, land-use status update investigative techniques, methods been marked improvement, there has been a lot of new technical routes and methods. Investigative techniques and methods of a comprehensive and diverse, efficient and practical, improved land use survey results and update the line with the actual situation and correct. These land use to update our investigation has entered a new stage of the technology. But updating land use survey as a basis of the investigation, technical difficulty, involves many areas, there are still many technical problems to be key breakthrough. In future, new methods should be further strengthened research, expand research ideas and methods to achieve a variety of integrated applications, a land-use dynamic real-time monitoring of the country's master land-use change change
