3S技术在土地资源管理与决策中的应用

The Applications of 3S Technology to the Management and Decision-making of Land Resources

3S技术是土地资源可持续利用研究中的高新技术。土地资源日新月异的变化使得传统的土地资源管理手段无法满足土地资源信息及时更新的要求。将 3S技术应用于土地资源科学的研究 ,一方面可弥补传统调查手段的不足 ,另一方面为土地资源的调查研究提供了新的途经与技术支持。本文在介绍 3S技术主要功能的基础上探讨了其在土地资源管理决策中的一些应用 ,对其应用前景进行了展望 ,指出 3S技术在土地资源研究中的系统化应用正朝着数据表达的可视化。

S technology are the modern research methods and tools in resources science. The rapid land use changes result in the difficulties in timely updating the information of land resources by using traditional methods. Applying 3S technology (RS?GPS?GIS) to land resources study can not only give a new method but also provide a strong technique support. On the basis of introduction the main functins of 3S technology, the passage discuses some applications of 3S technology in the management and decision-making of land resources, this paper also analyzed the prospect of 3S technology applied to land resources study.
