本文分析了“数字地球”这一全球战略思想带给我们的一些启示 ,这些启示包括 :战略眼光 ,大国地位 ,自主发展和技术引进 ,盲目追随、整合的意义等。笔者认为 ,宏观的、全局性的战略眼光 ,冷静思考与明确的目标 ,紧抓对地观测和国家基础信息设施建设以维护中国作为大国的形象和利益 ,在发展“数字中国”过程中走自主发展与技术引进相结合的道路 ,以及加强行政管理机制、智能化数据、科研机构和学科领域的整合 ,是我们在数字地球的挑战面前应有的基本思路。

This paper expounds some inspirations from Digital Earth, including strategic view, position of big power, self reliance & technical absorbing, blind following, importance of reorganization, etc. The author’s ideas are as follows: At first, we must have macroscopic & overall view of China’s development, analyzing the influence of DE to China, so as to lead China’s way of construction in a global oriented mode. Secondly, we should keep calm and make definite scheme about Digital Earth, and not follow the wave or DE blindly, thus utilize the idea of DE scientifically and rationally. Thirdly, in order to maintain its position of big power in the world, China should accomplish our scientific objectives, such as strengthening our development & construction on National Earth Observing System, Nation Spatial Data Infrastructure, etc. Fourthly, we should not only absorb and import the technologies from the developed countries, but also develop our own software & hardware system in self reliance way, and thus can construct Digital China successfully. Finally, we also have to make reorganization on administrative mechanism, intelligent data, science & technical units, as well as different academic realm. A wholly new science, Earth Information Science, will be created in the process of reorganization.
