海平面上升对珠江三角洲咸潮入侵的影响

海平面上升，潮汐作用加强，在无其它因素影响下，通常认为必然导致包括盐水入侵灾害加剧。根据河口盐淡水混合扩散原理，结合珠江三角洲河口整治延伸规划及河口淤积发展趋势，动态分析了海平面上升对珠江三角洲咸潮入侵的影响，认为海平面上升后，盐水入侵对珠江三角洲的影响总的来说不会加剧，而且还会逐步减弱。

EFFECT OF THE RISE OF SEA LEVEL ON THE SALINITY INTRUSION IN THE PEARL RIVER DELTA AREA

It is generally considered that with the rising of the sea level, if there is no other influencing factors, the tidal effect will be increasing, and the effect of salinity intrusion will also be increasing. According to the Principle of diffusion of the fresh and salt water at river mouth, in combination with the consideration of the planning reclamation projects at river outlets, and the trend of siltation at the river mouth, the effect of sea level rise on the salinty intrusion in the delta area is analyzed. The result shows that with the rise of the sea level, the effeCt of the salinity intrusion on the delta area will basically not be elhanced . On the contrary, the effect will gradually be weakened.
