The management and quality analysis of the primitive images have been analyzed and studied in this paper, of which the content and structure are as follows:Firstly, the developing background and the meaning of the management and quality analysis of the primitive image, as well as the trends of the management and data quality of the image database studied both in and out of our country, have been discussed in detail.Secondly, the developing direction of the technology of the remote sensing image and the importance of the remote sensing images in the field of economy nowadays have been analyzed systematically. And it is pointed that the primitive image with the elements of interior and exterior orientation will become more and more important as a sort of image production.Thirdly, the hierarchical structure of database, especially the SQL Server adopted in this system, has been deep studied and analyzed in the aspects of Applying Program Interface, Internet Data Connector and ActiveX Data Object.Fourthly, the methods of assessing the quality of the remote sensing image have been put forward in the terms of geometry, construction and the integrality of the assistant information.Fifthly, the model of propagation of errors of the precision of the ground coordinates has been calculated in the steps of inner orientation, spatial resection and answering based on the deep analysis of the principles and processes of inner direction and space resection, which have also been experimented and analyzed in term of numerical value.Finally, the total design and the idiographic realization of the sub-modules have been introduced in detail, based on which the design and development of this system are realized in combination with the program languages such as VB6.0, VC6.0 and SQL.

Futures Studies conceptualized in 1940, from 1960 to 1970 went through the peak of development in Philosophy of Science. The main proponents of Philosophy of Science, such as Positivism, Postpositivism and Critical Realism deeply influenced the futurists' ideas of the time concept in Future Studies. The understanding of time in Philosophy of Science continues the linear time frame of modern physics. Future is happening after the present event. In the field of Futures Studies, people expect futurists to predict futures accurately. When futurists are predicting futures, and mapping possible futures, they employ Holism and Utopian thinking. Karl Propper opposed Historicism of trying to plan a blueprint for society.

中文摘要未来学萌芽於一九四○年代，从一九六○年到一九七○年未来学历经了科学哲学发展的巅峰时期，科学哲学的思想滋养了未来学家的思考，其中实证论、后实证论与批判实在论这三种论点影响了未来学家在时间概念上思考方向，科学哲学对时间概念的理解延续了现代物理时间观上线性式看待时间的方式，未来是当前事件必然发生的结果；在未来学的领域里，成功预测未来是大众对未来学者的期待，当未来学者在预测未来，进行未来规划时，思想中预含了整体主义与乌托邦式的思考，Propper从反对历史定论主义的思想来驳斥建立社会蓝图的可能。
