中文摘要：

湖泊的岸线特征是表征湖泊形态特征的一项重要内容，应用分形理论对岱海湖泊的湖岸线形态变化进行研究，计算了湖泊岸线发育系数和湖泊岸线分维数。探讨了这两个标度的关系，并用来表征湖泊形态的动态变化。结果表明单一标度不能完整地表征湖泊的形态变化情况，还需要作长序列的研究。

英文摘要：

The characteristics of lake shoreline is one of important features of lake morphology. Based on the fractal theory, the morphology change of the lake shorelines in Daihai Lake was studied, and the shoreline development index and shoreline fractal dimension were calculated. The relationship between the two parameters were discussed and used to indicate the dynamic changes in the morphology of lake shorelines. It is concluded that one single parameter cannot adequately reflect the change in the morphology, and therefore further study is needed.
