基于多源遥感的皖江经济带资源环境调查应用研究

Research and application of resource and environmental survey in Wanjiang Economic Belt based on multi-source remote sensing

近年来,我国对地观测体系建设已进入快速发展的新时期,如何更好地发挥遥感卫星“巡天”的优势,及时、全面、客观地掌握区域资源环境的变化,具有重要的意义。本文以皖江经济带为研究区,着重在岸线资源、水环境、矿山环境、土壤湿度、地形地貌等方面开展图像分析和应用研究。结果表明,多载荷传感器的综合应用与分析可快速采集和定量提取有价值的专题信息,具有互补优势,可为本区域资源开发、保护利用和空间规划等提供数据支撑。

In recent years,the construction of our country’s earth observation system has entered a new period of rapid development.How to make better use of the advantages of remote sensing satellites for"surveying the sky"and to grasp the changes in regional resources and environment in a timely,high-frequency and comprehensive manner is of great significance.This paper took the Wanjiang Economic Belt as the research area,and focused on image analysis and application research in the aspects of coastline resources,water environment,mine environment,soil moisture,topography and landforms.The results showed that the comprehensive application and analysis of multi-load sensors could quickly collect and quantitatively extract valuable thematic information to provide data support for resource development,protection and utilization,and spatial planning in the region.
