| 摘 要： | 海平面上升加剧了珠江口门咸害入侵。在概述了珠江伶仃洋海区、磨刀门、鸡啼门、黄茅海各入海口门一般、枯期及汛期、高潮时，咸害入侵特点的基础上，根据Ｉｐｐｅｎ和Ｈａｒｌｏｍｅｎ的扩散理论和方法失算当海平面上升０．４～１．０ｍ时，各河口区咸害入侵距离的变化情况，得到枯期高潮时，虎门水道咸潮入侵距离增加１～３ｋｍ，最大约４ｋｍ，磨刀门水道咸潮入侵最大距离增加约３ｋｍ，黄茅海区，最大入侵距离增加５ｋｍ的结论。

| Abstract: | Rise of sea level has aggravated saline water intrusion at Pearl River's outlets. This paper gives a brief acanmt of characteristica of saline water intrusion in Lingdingyang Bay, Modaornen, Jitimen and Huangmaohai during different periods. Based on Ippen and Haromen' s diffusion theroy and method, the change of saline water intrusion in distance at the above-mentioned areas when the sea level rises by 0. 4m- 1. Om can be reckoned. It is concluded that during high tide in dry period,distance of saline water intrusion will increase by 1km- 3km with maximum distance about 4km in Humen Channel, maximum intrusion distance by about 3 km in Modaomen Channel and about 5 km in Huangniaohai area. |
