There are many bay-drowned-valley tidal inlets and Sandbar-lagoon tidal inlets in Hainan island. This paper selected two tipical deputies──Yanpu Bay-drowned-valley tidal inlet and Sanya sandbar-lagoon tidal inlet, analysed and compared their geomorphological structure and surface sedimentation. and got some conclutions: (1) The difference and the similarities of developmental models about bay-drowned-valley tidal inlet and sandbar-lagoon tidal inlet: (a) The bay-drowned-valley tidal inlet system has three...

There are many bay-drowned-valley tidal inlets and Sandbar-lagoon tidal inlets in Hainan island. This paper selected two tipical deputies──Yanpu Bay-drowned-valley tidal inlet and Sanya sandbar-lagoon tidal inlet, analysed and compared their geomorphological structure and surface sedimentation. and got some conclutions: (1) The difference and the similarities of developmental models about bay-drowned-valley tidal inlet and sandbar-lagoon tidal inlet: (a) The bay-drowned-valley tidal inlet system has three geomorphological units──tidal inlet and its flood tidal delta, ebb tidal delta. and so does sand bar-lagoon tidal inlet system; (b) The developmental scale of bay-drownedvalley tidal inlet is greater than that of Sanya sandbar-lagoon tidal inlet; (c) The developmental coefficients of flood tidal delta and ebb tidal delta of Yanpu tidal inlet are 0. 12 and 0. 44 respectively,those of Sanya tidal inlet are 1 and 2. 8 respectively. (2) The difference and similarities of sedimentary models about bay-drowned-valley tidal inlet and sandbar-lagoon tidal inlet: (a) In Yanpu baydrowned-valley tidal inlet, the grain size of sediments in tidal inlet is smaller than that on ebb tidal delta and flood tidal delta. In Sanya sandbar-lagoon. the grain size of sediments is greater than that on ebb tidal delta and flood tidal delta; (b) The grain size of sediments on all geomorphological units of bay-drowned-valley tidal inlet system is smaller than that of sandbar-lagoon tidal inlet system;(c) The heavy mineral contents and ZTR of sediments in Yanpu bay-drowned-valley tidal inlet are higher than those in Sanya sand bar-lagoon tidal inlet: (d) The heavy mineral combinations of sediments on bay-drowned-valley inlet and its ebb delta and flood tidal delta are different. The heavy mineral combinations of sediments on sandbar-lagoon tidal inlet and its ebb delta and nab tidal delta are the same; (e) The foraminifer genus-Ammonia and Elphdium are common in both of the two type tidal inlets; (f) The sediments of Sanya Yuzan stream outlet have many Nummulites and Cellanthas, but that in the Yanpu area has no such materials. (3) The stability of bay-drowned-valley tidal inlet in better than that of sand-bar-lagoon tidal inlet.

海南岛存在着大量港湾溺谷型和砂坝泻湖型潮汐汊道。本文以两类潮汐汊道的典型──三亚砂坝泻湖型潮汐汊道和洋浦港湾溺谷型潮汐汊道为例,分析了两类潮汐汊道的成因和地貌发育体系;研究了两类潮汐汊道的现代沉积特征(粒度、重矿、地球化学、有孔虫);对比了两类潮汐汊道的发育模式和沉积模式;探讨了两类潮汐汊道的稳定性。

On the basis of environmenta1 va1ue classification and the view of environmenta1 economics, the concept of scarcity degree of environmental resource is put forward with the consideration of the characteristics environmental resource and the social and economic relationship between the supply and requirement of environmental resource. A new method to measure ecological value is also set up by using the developmental coefficient. This makes the method perfect to the others which talks about environment just according to the environment or uncomprehensive background of its social econmmics. It has been used in the case of water environmental function loss of Beijing, and the result is that a cumulated loss of 8. 569 billions yuan has been brought out which is caused by water pollution in the past 20 years.

在介绍环境价值一般分类的基础上 ,从环境经济学角度考察环境资源的供给与需求的社会经济关系及其环境资源的自身特点等 ,提出了环境资源紧缺度的概念并利用环境生态价值的发展阶段系数 ,构造了环境生态价值的估算方法 ,解决了其他算法就环境论环境或没有充分考虑其社会经济背景的缺陷 ,并以北京市水污染造成的水环境生态价值损失为例进行了估算 .计算结果表明 ,近 2 0年来 ,北京市由于水资源紧缺造成的环境生态价值损失累积为 85 .69亿元 .
