基于国产卫星影像的自然资源动态监测

准确及时地掌握山、水、林、田、湖、草系统变化状况，是自然资源管理重点关注的问题。卫星遥感技术具有宏观、综合、动态、快速的特点，能够应用于自然资源领域开展目标识别、信息采集与处理、分析与评估等工作，可作为自然资源监测的有效手段。本文以“土地、矿产、海洋”等重要自然资源要素为动态监测研究目标，基于多源多时相国产卫星遥感影像数据和各类审批、规划专题资料数据，开展自然资源动态监测研究。研究结果表明，深入挖掘国产卫星影像资源潜力，实现自然资源精细遥感监测服务模式是切实可行与高效的。

Dynamic monitoring of natural resources based on the domestic satellite images

It is an important problem of natural resources management to master the overall change of the mountains, rivers, forests, farmlands, lakes and grasslands accurately and timely. With the characteristics of macro, comprehensive, dynamic and fast, satellite remote sensing technology can be applied in the field of natural resources to carry out target identification, information collection and processing, analysis and evaluation. It can be used as an effective means for natural resources monitoring. This paper takes land, mineral and ocean as the research objectives to carry out the dynamic monitoring of natural resources based on multi-source and multi-temporal domestic satellite remote sensing data and kinds of approved and planned data. The results show that it is feasible and efficient to explore the potentials of domestic satellite images deeply as a way to realize the precise remote sensing monitoring of natural resources.
