山东半岛潟湖湿地发育特征及区域分异演化研究

Study on Developmental Characteristics and Regional Differential Evolution of Lagoonal Wetlands Along the Shandong Peninsula

根据区域环境差异,将山东半岛沿岸划分为6个不同岸段,对不同岸段湖湿地的发育程度进行了统计。计算表明,山东半岛不同岸段湖湿地的发育程度是不同的,其中平直沙质海岸和开敞、半开敞性岬湾海岸的湖湿地比较发育,封闭性较好的岬湾海岸湖湿地则发育程度较差。同时,根据湖湿地的水文特征,把山东半岛湖湿地划分为成水湖、半咸水湖、淡水湖和近代埋藏湖四种类型,并对山东半岛不同岸段湖湿地的区域分异演化进行了阐述。

According to the difference in regional environment, the coasts of Shandong Peninsula can be divided into six coastal sections, and the statistics on development levels of lagoonal wetlands in differentcoastal sections are made. It is shown from the calculated results that the development levels of lagoonalwetlands in six sections are different, among them, the straight and sandy coasts and the coasts with openor semi-closed bays have well-developed lagoonal wetlands, and the coasts with closed bays have poorly developed lagoonal wetlands. Moreover, according to the hydrographic characteristics of lagoonal wetlands,the lagoonal wetlands along the Shandong Peninsula can be classified into four types, saltwater lagoon,brackish water lagoon, freshwater lagoon and modern buried lagoon, and the regional differential evolutionof lagoonal wetlands along the Shandong Peninsula is described as well.
