摘要
河口是具有高生产力与多样性的水陆物质交换区域。受小流域环境的影响,不同入湖河口的地貌与水文特征差异显著,致使河口种类繁多。从自然地理与水动力两方面独立分析了影响入湖河口形态及冲淤变化的主要因素,分别以此为基础划分河口类型。根据水动力分类指标,得出环太湖河口的6种基本类型。针对不同的环境压力,预测入湖河口形态受人类活动影响的演变趋势,为建设入湖河口管理区与生态修复模式提供思路。
The estuary is a highly productive and diverse exchange area of land and water.Affected by the environment of small watersheds,the landform and hydrological characteristics of different estuaries into the lake are significantly different,resulting in a wide variety of estuaries.In this study,the main factors affecting the morphology and dredging changes of estuaries into the lake are independently analyzed from the aspects of physical geography and hydrodynamics,and the types of estuaries are divided on this basis.According to the hydrodynamic classification index,6 basic types of estuaries around Taihu Lake are obtained.In view of different environmental pressures,the evolution trend of the inlet estuary morphology affected by human activities is predicted,and useful ideas are provided for construction of estuary management area and ecological restoration model.
