随着遥感技术逐步趋于成熟以及今后几年内计划将要发射的空间飞行器数量日益增长，一个重要的问题摆在了我们的面前，即在过去的２５年内对地观测系统产生了何种重要的经济影响？又因为对地观测系统耗资如此巨大，所以更重要的也许是系统对未来经济和社会将造成什么影响、它的重要性何在、我们又将怎样使其超越过去以加强其对未来社会和经济的影响等问题。本文根据几个简单但却很能说明问题的模型来讨论上述问题。 As remote sensing technologies mature and the number of space vehicles planned to be launched in the coming years is growing, an important issue lies before us: what is the important economy for earth observation systems in the past 25 years influences? And because the Earth observation system is so costly, perhaps more importantly, what is the impact the system will have on the economy and society in the future, what is its importance and how we can move it beyond the past to strengthen its future social and economic Impact and other issues. This article discusses the issues above based on a few simple but very informative models.
