人——地系统的结构、潜力和演化——以河南省东部平原为例

STRUCTURE, POTENTIAL AND EVOLUTION OF MAN-EARTH SYSTEM IN PLAIN OF ZAST HENAN PROVINCE

本文就河南东部平原区用模型方法分析了平原类型的人—地系统的结构、潜力和演变过程。

The structure of a regional man - earth system frequently is in a state of dynamic equilibrium through the interaction and feedback among the basic factor sets. Food as a core junction point between man and earth decides the spatial structure of the man-earth system. The interactive potential between man and earth has a hierarchizatior, in which the most foundational potential is the input-output potential. The spontaneity in evolution of the man-earth system demands to be adjusted and controlled. Regulating some controllable parameters of the system, we can harmonize the relation between man and earth. Taking the plain of east Henan Province as a instance, this paper initially analysis the structure, potential and evolution of the man-earth system of plain types with modelling methods.
