The epigeosphere is a complex dynamic open gigantic system. With the development of human society，the interaction between man and nature in the epigeosphere composes a compound system of nalure，society and economics, namely，man一land system. In the epigeosphere and man-land system，material，energy and information are migrated，exchanged and transported among the inner of each sphere and the boundary surface，the inner of each region and the regional boundary.  With the rapid
increase of population and quick development of industry and city，resource exhaust and environmental demage seriously influence economical development and social progress day by day. So we must deeply study the epigeosphere dynamics and its mechanism，probe into man一nature interaction and the regulation principle of man-land system，explore coordinate developmental models of population，resource，environment and economics.
    This paper analyzes the research aim,significance,international development and national foundalion of the epige}phere dynamic mechanism and regulation of the man-land system，and put forward concrete proposals of the guiding ideology，research aim and content of this project.
