In recent years,with the high speed development of economy in Pearl River delta, infrastructure investment for water resource,traffic,environmental protection is growing.It is increasingly urgent for understanding river nets system and discharge distribution ratio variation of main connection nodes.Discharge distribution ratio of each nodes is relative to the runoff of upper boundary and the tidal power of lower boundary.The Pearl River estuary is divided into far mouth section,near mouth section and estuary section.Discharge distribution ratio of every section varieties with upper and lower boundary conditions.In this paper,Based on the observational data of June in 1998 and June in 2005,combining with history data,analysis discharge distribution ratio variation of main connection nodes of the Pearl River delta.and set up a mathematical model to simulate flow variation characters.The conclusion is, in recent years Discharge distribution ratio of the east four outlets increases, namely the ratio of West River flowing into North River and North River into the main channel of the Pearl River.with the flood discharge increasing,The ratio of the longitudinal branches occupies the smaller proportion than that of latitude branches.
