| 摘 要： | 科学技术本来就是双刃剑。“数字地球”战略可能有助于全球信息资源的共享，全球化经济贸易的繁荣，同时也威胁着发展中国家的权益与安全。中国既要积极参与，更要独立自主。实现国家信息化建设是基础；应付“数字地球”的挑战是对策，不能混淆，不能等同。各国不是站在同一起跑线上出发的。必须扬长避短，发挥优势，及时占据制高点。

| Abstract: | The strategy ofthe Digital Earth While it could be athoughtforglobalstrategy,itcould also bea sword of Damocles,foritnotonlyinvolves knowl edge property ,international collaboration ,data sharing and so on ,itservesinternationaltrade,economic development, remote education as well.Additionally ,it hasinfluence on nationalsecurity,governmentalrights and ethnic dignity. (2) The basic policy of China For developing countries,the Digital Earth Strategyis more like a challengethan an opportunity. While China in sistsits opening policy ,italso needsto enhanceits ability to compete in a global context,formingits own independent andintegrativeframeworkin data acquisition ,updating,storing ,circulation and mining .There exitneedsto distinguish the domestic needs from international exchange,and national informationalization from countermeasures to the Digital Earthstrategy.Theseshould be no mixtureofconceptsandidenticalactions.Chinathrowsspecialattention onthe Digital Earth strategy forthe world peace and Regionalsustainable. (3) The starting pointin science and technology Since countries are notstarting atthesome place,China mustrely on its advantage and avoid itsinferior positionin developing science and technology to take the master point.In the Agenda 21st, Chinese government introduced more than 40 projectsinvolvinginformation systems;and Chinesescientistsalsoforesaw the digitaltrendin geo science andits prospectsin servingthe society,therefore have been taken partin much cooperation in globalresearches context. In 21st century ,the Digital Earth strategy should not bethe arms of hegemony,instead itshouldimprovethe pros perity of human society in following areas;(1)specialization ofsmallsatellite;(2) database update through satellite in formation and data sharing;(3) contentofchlorophylland assessmentofprimary productivity ;(4) thermalfield ofearth surface and monitoring on radio temperature;(5) spectral difference of geo chemicallandscape.Itcan help solve some environmentalproblems brought by the global change,and help reallocate resources in achieving sustainable develop ment. |
