运用信息熵时2004-2008年广东省及其六大流域用水结构系统的无序程度进行测算.结果表明,广东省用水信息熵和均衡度呈增长趋势,西江流域、北江流域、东江流域、珠江流域、韩江及粤东诸河和粤西诸河六大流域用水信息熵和均街度也有不同程度的增加,表明广东以及六大流域的用水结构系统在不断调整的过程中由非平衡状态向平衡状态演变,同时根据各大流域用水结构系统演变的特点,呈现了4种不同演化类型.%Information entropy was applied to measure disorder degree of watershed complex meta-system in Guangdong Province and other six rivers from 2004 to 2008. Results suggested that the balance degree and information entropy of water resource structure was rising and the water resource structure system was being stable in Guangdong Province. The Xijiang River, North River Basin, the East River Basin, the Pearl River, Hanjiang and the western Guangdong River, and other basins information entropy and balance degree of water resource system was also increasing in different scales. The results showed that the water structure system in Guangdong and other six rivers evolved from nonequilibrium to equilibrium in the process of continuous adjustment. In the meantime, according to the characteristics of water structure system evolvement in each rivers showed four different transformation types.
