长江河口盐水入侵影响因子分析

The Analysis of Factors Affecting the Saltwater Intrusion in Changjiang Estuary

本文根据大量实测资料，研究了径流、潮汐、地形等几个重要因子对长江口盐水入侵的影响，并对长江口盐度变化的一些特殊现象作了初步解释，还探讨了北支盐水倒灌的基本规律及其对南支盐度变化的重要意义。

Based on several - years observation data in Changjiang estuary, this paper analyse the main factors including discharg, tide and estuarine geometry which affect the vallation of saltwaer intrusion.Some special slatwater intrusion phenomena in the estuary are studied in detall. The variation and importance of 'backward fiowing' of saltwater from North Branch are also discussed.
