利用卫星遥感技术监测赤潮的研究

赤潮灾害的频繁发生，给海洋生态环境和海洋渔业经济造成了严重危害。卫星遥感技术的不断完善，为快速、有效地动态监测赤潮灾害提供了可能，通过卫星图片的校正、合成、分析、解释、判断分析，可以迅速连续地掌握赤潮的发生状况，对于研究防控和治理赤潮灾害有着十分重要的意义，本文就如何利用卫星遥感技术监测赤潮进行了探讨。     

An ecological study on the fouling organisms in Yantai Harbour

Yantai Harbour (37°33′15″N , 121°23′42″E) is situated at the north coast of Shandong Peninsula and is a large fishing and commercial port of North China. From June 1983 to May 1984, a yearly panel test on fouling organisms was carried out at the non-fixed jetties in the inner and outer harbour. The test method was according to "the Marine Survey

Summer Arctic sea fog

I~IOXSea fog is a kind of dangerous weather. Chinese sea fog experts, Wang Binhua (1983),Hu Ruijin and Zhou Faxiu (1998) and Hu Jifu et al. (1996) studied sea fog rather Systematically. FOreign Experts also Paid great attention to sea fog. Ernlnons and Montgomery(1974), chipper (1994) and Rayrnond et al. (1989) have studied sea fog thorOUghly.HOwever, studies on Arctic sea ice have rarely been carried Out becauSe of the sever environment and less htnnan activity in the region. There …     

青岛文昌鱼的生活史──年龄、生长和死亡研究

于１９８９年８月－１９９０年７月对青岛文昌鱼的生活史进行研究。结果表明：（１）青岛文昌鱼种群由４个齿组组成，它至少生产４ａ以上，甚至可达６ａ左右。（２）在Ⅰ、Ⅱ齿时生长较快，平均年生长１３－１５ｍｍ，Ⅲ龄后生长速度减慢，即使同一年龄组的文晶鱼，在不同季节其生长速度也不同。（３）在冬春采集的文昌鱼中Ⅲ龄组的峰值较小。（４）繁殖季节过后，老龄文昌鱼因衰老而死亡。     

Molecular identification of bloom-forming species Phaeocystis globosa(Prymnesiophyta)and its dispersal based on rDNA ITS sequence analysis

Abstract-The colony-forming Phaeocystis species are causative agents of dense bloom occurrences incoastal waters worldwide. It is difficult to separate them because of the different morphologies associatedwith their colonial stages. In this study we applied molecular approaches to analyze the genetic variationof Phaeocystis globosa and Phaeocystis pouchetii from several geogrtaphic regions, and to assist in tracingthe dispersal of bloom-forming Phaeocystis species in coastal waters of China. The Sequences of the inter-nal transcribed sacers (ITS1 and ITS2) of rDNA and the 5.8S ribosomal RNA gene of Phaeocystisstrains were determined. Sequence comparison shows that P.globosa was the most divergent toP. pouchetii, exhibiting sequence divergence higher than 0.08. However, lower genetic divergences ex-isted between strains of P.globosa. The sequence comparison of the Phaeocystis rDNA ITS clearlyshows that the species isolated from the southeast coast of China is identified as P. globosa rather thanP. cf. po     

关于我国金枪鱼围网渔业发展问题的几点探讨

本文通过对联合国粮农组织公布的1989－1998年金枪鱼渔获量的分析，清晰了我国发展金枪鱼围网渔业的趋势，并着重对于围网生产密切相关的渔场选择、捕捞技术进行了几点探讨，还对开发科研工作谈了个人看法。     

舟山外钓山海岸边坡泥沙动力与冲淤演变特征

通过对研究区海域的水文泥沙进行现场测验,对比1960-1962年海图、1995年和2001年水下地形图三期地形数据和分析浅地层探测数据等方法,分析了舟山外钓山岛西海岸边坡的水动力、悬浮泥沙及冲淤特征,探讨了海岸边坡发育演变的模式与机制。研究结果表明,在基岩岬角海岸与潮流深槽的边界控制及往复潮流的作用下,舟山外钓山岛西海岸边坡演变是一个"上淤下冲"的模式,即边坡变陡至边坡土体失稳并在不定期外力触发下滑塌堆积坡脚,然后上部重新淤积、下部滑坡体不断被侵蚀的循环过程。     

海岸带可持续发展及其指标体系研究--以辽宁省海岸带部分城市为例

海岸带有着丰富的资源，能够为人类社会的可持续发展提供强大的物质基础，而它对外界的影响又是相当敏感的，因此海岸带自身的可持续发展理应受到人们的关注。本文根据可持续发展理论的基本原理，提出海岸带可持续发展的概念，阐述了海岸带可持续发展的基本内涵，并建立了其评价指标体系。文章最后以辽宁省海岸带部分城市为例，介绍了海岸带可持续发展的具体评价方法，为合理开发利用海岸带提供了依据。
