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 水系的發(fā)育受氣候構(gòu)造運動和人類活動的顯著影響,構(gòu)造運動狀況的差異必然反映在水系特征上。通過對膠東半島水系的展布方向水系分形諸水系特征的統(tǒng)計分析,揭示出水系受新構(gòu)造運動有較明顯的響應(yīng),桃村東陡山斷裂是本地區(qū)東西部新構(gòu)造上的主要分界。
