Abstract: For river networks, its growth subjects are notably influenced by climate, geotectonic movement, and mankind actions. And its character certainly reflects the different conditions of geotectonic movement. Statistical analysis of some characters of the river networks including the river direction's, the geometric fractal of main river's and the river network density's in Jiaodong peninsula showed that the river networks respond obviously to the neotectonic movement. The area is mainly divided into the west part and the east part by Taocun-Dongdoushan fault during neotectonic movement.

Key words: Jiaodong peninsula, river networks, statistical analysis

摘要： 水系的发育受气候、构造运动和人类活动的显著影响，构造运动状况的差异必然反映在水系特征上。通过对胶东半岛水系的展布方向、水系分形、诸水系特征的统计分析，揭示出水系受新构造运动有较明显的响应，桃村—东陡山断裂是本地区东、西部新构造上的主要分界。
