The Lagoon of Venice： geological setting,evolution and land subsidence

The paper deals with the geological setting, history and subsidence of the Venetian Plain. Major attention is paid to the Pleistocene-Holocene stratigraphic sequence in the Lagoon of Venice, in relation to its origin that datesback to 6-7 kyr BP. Geological land subsidence, which played an important role in the origin and the evolution of the lagoon, and anthropogenic subsidence, that has recently assumed a major importance for the Venetian environment, are discussed. Considering also the sealevel rise, 23 cm loss in land elevation has occurred in the last century, leading to increased flooding events and environmental problems that require protective works.

台湾海峡中北部表层沉积物中介形类拟生态的研究

台湾海峡中北部介形类共６９属１１５种，受复杂的海底地形及海流、水团等环境因素影响，分为４个分布区；沿岸低值区，西南部高富集区，东北部密集区及中部过渡区，介形类属种以东海、南海组成的分子较多，显示出海流因素起主要作用。     

渤、黄、东海水团多年月平均分布与变化的初步分析

本文从浅海水团的变性特点出发,根据多年月平均的温盐资料,以温盐点聚图为基础,采用模糊聚类法,划分渤、黄、东海逐月表底层水团。文中着重探讨整个渤、黄、东海陆架区各水团的基本特征、消长规律及其与渔场的关系。
