论地理系统结构

On The Structure of Geographic System

以现代系统科学理论为依据，结合一些生动的地理系统演变事例，对地理系统的结构特征与构型作了总结和探讨，并着重分析了系统的稳定性和可变性对地理系统结构的影响．提出：要改变系统地理环境的功能，就必须先识别其结构构型，认清系统内部的相互作用机制，然后才能改变系统要素，调整系统结构。

The structure of geographic system is discussed.They are time structure,space structure,quantity structure,balance structure and unbalance structure etc.The writers think that the structure of geographic system has double stability and changiblity.If you want to change geographic cycling,you have to differentiate its model of structure at first.Untill the geographic system work well,you must not stop adjusting systematic actors.
