人类的发展正在受到环境不断恶化、资源日益匮乏的挑战。但是由于受自然条件限制,许多丰富的资源至今仍处于“养在深闺人未识”的局面。在那些人迹罕至的深山老林、茫茫沙漠和浩瀚的大海,蕴藏着人类赖以生存的资源。怎样去发现它们?对于地球大气环境的勘查、自然灾害的观察、农作物生长情况评估、水土资源调查等等。都给人类提出了一道道严峻的课题。在长期的生产实践中,人们越来越感到用传统的方法,即便是航空遥感也无法满足人类的要求。气象卫星的发射成功,开创了人类从新的高度和新的视角观察地球的新天地。因此,地球资源卫星应运而生。 Human development is being challenged by deteriorating conditions and increasingly scarce resources. However, due to the restriction of natural conditions, many rich resources are still in a situation where “they are not recognized by the purdah”. In those inaccessible deep forests, vast deserts and the vast sea, contains the human resources on which to live. How to find them? For the Earth’s atmospheric environment exploration, observation of natural disasters, crop growth assessment, water and land resources survey and so on. All of them pose a serious issue to mankind. In the long-term production practice, people are more and more aware of the traditional methods, even the remote sensing of the air can not meet human needs. The success of the launching of meteorological satellites has created a new world for mankind to observe the earth from a new height and a new perspective. Therefore, the earth resources satellite came into being.
