摘要
自然地理环境中的河道,可以看作是prigogine所定义的开放系统,这时出现的稳定态,一个充分小的宏观局域内热力学性质是一致的,但不同的宏观局域性质不同,它们形成了一种有序结构一一耗散结构。本文试图结合实际问题,探讨地理系统的动力学性质。
River channel in natural geographical environment can be regarded as an open system defined by Prigogine, This paper approaches the formation of dissipative structure and analyzes river channel change with the theory of dissipative structure. The dynamic characteristics of river channels are shown in conclusions 1—5.
