摘要
要素流是人地关系地域系统内和系统同外界环境之间联系的纽带与桥梁.正是通过要素的有机滚动及其组合,各个系统之间才产生正反馈与负反馈,才构成一定时空条件下的人地关系地域系统.研究要素流是人地关系地域系统进行研究的根本.本文对要素流的概念进行了界定,总结了要素流动与组合的特点,阐释了要素流动的影响机制及其遵循规律.
Man - land relationship areal system is made up of many sub - systems, such as population system, resource system, environmental system, society system and so on. In fact, each of them doesn＇ t exist by itself. They contact closely and interat by element flow, and promote the movement of whole system. The key elements are the bridge, which contact inside and external world together. Through the flow and association of the key elements, a subsystem is connected with each other, and then form man- land relationship areal system under the conditions of special space- time. With the evolvement of man- land relationship areal system, the element＇s quantity, kind, arrangement, combination mode, collocation efficiency and function mechanism of the sub- system change accordingly. So,the element flow is the base of research. The paper puts forth the concept of the element flow and summarizes the characteristics of the flow and combination of dey elements, then sets forth the affection mechanism and following rule on the flow of dey elements. The paper gives and eamphases on the study of element flow in the socioeconomic system, and only simple in the nature ecology system.
