下荆江河流是一个耗散系统，其平面形态具有分形结构，这种分形结构形成的物理机制之一是河流系统内部诸因素之间（如河床与含沙水流）及河流内部与外部环境（如流域）因素之间存在复杂的非线性依存关系和非线性相互作用，系统外界的扰动如洞庭湖顶托或各种人类活动（如沿江围垸）等是下荆江河型突变的触发力量。
下荊江河流是一箇耗散繫統，其平麵形態具有分形結構，這種分形結構形成的物理機製之一是河流繫統內部諸因素之間（如河床與含沙水流）及河流內部與外部環境（如流域）因素之間存在複雜的非線性依存關繫和非線性相互作用，繫統外界的擾動如洞庭湖頂託或各種人類活動（如沿江圍垸）等是下荊江河型突變的觸髮力量。

The Lower Jingjiang River is a dissipative system .Its platform has fractal structures .One of the physical mechanisms to generate this fractal sinuosity is the complex nonlinear connections and nonlinear correlations among various factors in the river system such as bed system ,muddy water ,as well as factors between the river internal and its external environment such as basin factors .The external distur-bance such as jacking of the Dongting Lake and activities of the mankind are the touching forces leading to the sudden change of the river pattern of the Lower Jingjiang .
