| 摘 要： | 通过对珠江口30多年相对海平面和近15年绝对海平面变化的研究，比较1992年12月～2008年12月南海卫星观测和珠江口验潮站观测的海平面变化趋势，认为珠江口的相对海平面（RSL）上升最主要原因是全球气候变暖、海平面上升所致；通过研究29个冬季各月西、北江冬季径流量、海平面、表层盐度的变化趋势，以及强咸潮月份的径流、海平面、盐度的对应关系，得出海平面上升是加大咸潮影响的重要因素。

| Abstract: | By analysis on the change of the relative sea level （RSL）in recent 30 years and the absolute sea level （ASL） in recent 15 years around the Pearl River Estuary and by comparison of the trends of sea level change between from satellite over South China Sea and from the tide gauges during Dec 1992 to Dec 2008, it is found that the cause of RSL rise around the Pearl River Estuary is mainly due to global warming and the consequent ASL rise; and that the rise of sea level plays an important role in the increase of the saline water disasters by analyzing the change trends of water discharge, sea level, and sea surface salinity of Xijiang and Beijiang River in recent 29 winters as well as the related severe saline water intrusion. |
