硇洲岛潮间带软体动物分布和区系研究

对硇洲岛的潮间带软体动物进行了采集调查，共鉴定软体动物148种（未包括头足纲），分属51科，其中多板纲1科1种，腹足纲33科84种，瓣鳃纲17科63种。分析表明，其区系特点是以南海亚热带-热带种和东海、南海亚热带种为主要成分，且有部分热带种已发展成优势种。     

台湾岛南部海域温跃层个例特征分析

利用台湾岛南部海域若干观测点的水温垂直分布资料,计算了各研究个例的温跃层要素,并进行了较为详细的分析.结果表明：台湾岛南部海域春、夏、秋、冬均有温跃层存在,其中以多跃层为主,每一跃层厚度较小.太阳辐射的强弱会影响跃层的强度;大风、寒潮等灾害性天气对第 1层温跃层的深度影响较大,但对强度和厚度的影响不明显;海流因素会影响到第 1层温跃层的深度和强度;地形也可能是影响第 1层温跃层深度和强度的重要原因之一.分析结果对认识该海域海洋温跃层的分布特征可以提供有益的参考.     

High—resolution records of Holocene from the Shuangchi Maar Lake in Hainan Island

The results of sedimentary characteristics,grain-size,clay mineral,C/N and pollen analysis reveal the evolution history of the Shuangchi Maar Lake of Hainan Island as well as the short-term climate variations in tropical areas.It is testified that the Maar sediment system was sensitive in recording the rapid climate changes in the Holocene.These multidisciplinary results demonstrate that the thermal maximum in the Holocene climate lasted from 7200 to 2700 aBP,with serveral abrupt ephemeral vibrations occurring between 7250-6120aBP and at around 4460,3850 and 2700 aBP.In the late Holocent,particularly at -2700 aBP,a distinct environmental change indicating an important climate transition in the tropical eastern Asia was recorded,probably responding to the enhancement of ENSO phenomena in the Pacific Ocean.In addition,the high-resolution algae record clearly indicates periodical climate fluctuations at 500 a cyclicity during the last 2500 years.

浙江洞头岛潮间带软体动物的生态调查

作者在历年的海滨动物采集中，整理出洞头岛潮间带贝类１０８种。不同底质条件下，以岩礁相的种类、生物量、栖息密度最高；砾石块石相次之；泥滩中生物较贫乏，沙滩中最少。本文还就贝类在潮间带的生活类型、在不同潮区的分布及数量分布作了描述，对几种经济贝类的利用、资源保护作了分析。     

Body size variability and water balance: A comparison between mainland and island populations ofMastomys huberti (Rodentia: Muridae) in Senegal

Generally rodents are found to be larger on islands than on the mainland. However, there are some exceptions to this rule, and the aim of this paper is to examine one of them. On the mainland of Senegal,Mastomys huberti occupies humid habitats. However, it occurs also on dry and sandy islands (Saloum delta), where its representatives are dwarf. Since water availability appeared to be the limiting factor in these islands when compared to the mainland, we studied water turnover characteristics in relation to body size, in mainland and island populations at the end of the dry season, under both field and laboratory conditions. All populations were found to be water balanced in their natural habitats. They presented similar rates of water turnover, even though island animals were subjected to stronger constraints than mainland ones. Laboratory experiments suggested that the physiological plasticity of one of the island populations may be reduced. Island populations have a higher kidney size to body weight ratio than those from the mainland. We propose that smaller size in the islands allows the maintenance of water balance with a smaller amount of water, and that a higher ratio of kidney filtration surface to body size may helpMastomys huberti to survive in dry islands. We discuss the factors responsible for body size variability and variation in water exchange characteristics and conclude that different factors could explain body size variation among island populations, depending on the species considered and the ecological constraints met within the islands.

南海和东海板块构造演化的几个问题

本文就南海、东海及台湾板块构造演化的若干问题展开讨论。我们认为南海海盆是在被动大陆边缘的基础上张开的，而不是弧后扩张的产物；台湾不是活动岛弧．而是典型的岛弧‘大陆碰撞带，并将台湾与鲁马拉雅地区的构造作了对比；吕宋至台湾的板块边缘显示出板块俯冲至碰撞的转化．南海东缘板块边界演化的基本趋势是．从俯冲到碰撞．进而形成极性相反的新俯冲带．南海海盆终将成为被地块全面包围的残留盆地；南海的开合表现为威尔逊旋回的复杂形式。认为冲绳海槽尚未出现伴有新洋壳形成的海底扩张作用．冲绳海槽是弧后裂陷．而非弧后扩张的产物。     

英国“光辉孤立”政策的文化渊源浅析

英国在19世纪下半叶的外交政策被描述为“光辉孤立”，这是英国在强国林立的欧洲保持自身政策灵活性和追求利益最大化的关键。就政治因素来看，“光辉孤立”是均势外交的一种表现，但深究其文化渊源，“光辉孤立”是英国政治传统中的保守主义和功利主义、外交文化中的制衡观念以及不列颠民族特性和岛国文化的综合结果。
