通过对珠江口磨刀门水域包括潮位、径流量、河道深泓、海表水温、盐度、气温、风速、风向、降雨等参数的长期基础历史资料的整理、转换与统计分析，探讨其盐水入侵加强的主要原因。结果表明：珠江口磨刀门盐水入侵受到潮位、径流、降雨、气温、风速的等诸多因素的综合影响，但最直接、最明显的影响因素是径潮相互作用。多因素的综合作用，使得珠江口磨刀门的盐水入侵活动规律复杂多变，给预报和治理工作带来一定的困难。

The principal component analysis on hydrologic and meteorological factors that led to saltwater intrusion was carried out. The statistic results revealed that the relative strength of river flow and tide was the main causal factor even though many other factors including tide,runoff,rainfall,temperature and wind also had effect on the saltwater intrusion occurred in the Modaomen estuary.
