摘要:

根据实测资料分析了广州水道的成潮变化规律及其主要影响因素．根据盐度数学模型计算了地形、海平面、风况和流量分配方式4种因素对咸潮的影响程度，结果表明，年内流量分配方式对成界的影响最明显，其次是地形和风况的变化，海平面抬升对成潮影响相对较小．

Analysis of factors affecting saline water intrusion in Guangzhou waterway

MO Si-ping¹,LI Yue²,LU Su-lan²

Abstract:

Based on field data, this paper analyzes the impact of saline water intrusion on Guangzhou waterway and identifies the dominant factors determining the variation of saline water tide. Furthermore, by the use of salinity mathematical model, the degree of effects of four factors, i. e. , terrain, sea level, wind regime and flow rate distribution on saline water tide variation, is presented respectively. Among these factors, flow rate distribution has significant effects on the saline water boundary, terrain and wind regime have less significant effects on it, and the sea level can affect the saline water tide weakly.

Key words: saline water intrusion terrain sea level wind regime runoff salinity mathematical model Guangzhou waterway
