区域海洋地质数据库建设纲要

区域海洋地质数据库是中国地质调查局基础数据库的一个重要组成部分，是实现地质调查基础性与公益性战略部署的依托。根据区域海洋地质数据库建设的目标与任务，在数据结构和实施步骤等方面进行了初步研究。区域海洋地质数据库及其管理信息系统适合采取基于Web系统的三层体系结构，在数据构成上亦分为区域海洋地质调查原始资料与成果资料，其中元数据库的建设对数据库的应用非常重要，用户可以通过元数据了解数据的存在性、适宜性、有效性等，确定数据的使用方法，因此，元数据库的建设应采用国际已经普遍认可的ISO/TC211发布的ISO19115空间元数据标准。     

我国海域分等定级指标体系研究

长期以来,海域的无偿使用导致海洋开发活动秩序混乱、海洋环境污染加剧、海洋生物资源枯竭、海洋生态环境遭到破坏,严重阻碍和制约沿海地区的可持续发展.本文试图根据经济学的“地租级差”理论和运筹学中的“层次分析法”并结合我国沿海11个省、市和自治区的社会、经济、基础设施、自然资源等因素进行理论探讨,给出了我国管辖海域的等级.为今后我国制定海域有偿使用金的征收标准奠定基础.     

Embryonic and larval development of Babylonia formosae habei (Altena and Gittenberger, 1981) (Gastropoda:Buccinidae) on China''''s coast

The development of embryos and larvae of Babylonia formosae habei living along the southeast coast of China is observed under laboratory conditions. The egg masses are laid by females on hard substrate at night and each capsule contains 100-500 eggs. Each egg is 250-280 mm in diameter. The first two cleavages of the embryo are meridional and equal, and a polar lobe is produced. Larval kidney, which only consists of a single cell, appears during the gastrula stage on each side of the embryo. The right tentacle develops prior to the left one. At 25-27℃, an intracapsulate veliger stage is reached about 4.5 d after deposition. The larvae hatch on the fifth day as swimming veligers with a shell length of 360 -500 mm. The newly hatched larva can ingest suspended algal cells from the water column and remains in the pelagic stage for 8-10 d. The newly settled juveniles are 900-1 200 mm in shell length.

皱纹盘鲍对氯霉素的通透性吸收与扩散

在海水溶液中的氯霉素分子可以越过皱纹盘鲍Ｈａｌｉｏｔｉｓ ｄｉｓｃｕｓ ｈａｎｎａｉ Ｉｎｏ的体表结构进入其血淋巴液中。鲍血淋巴液中氯霉素的浓度与药浴液的氯霉素浓度，温度均呈线性关系，药浴时间的效应表现的Ｓ形逼近曲线。在２０℃的海水中，鲍血淋巴液中的氯霉素向体外扩散的半衰期为４２ｍｉｎ。

2-D TIDAL FLOW BY OPERATOR-SPLITTING METHOD

In this paper, the method of operator splitte is applied to simulate the tidal flow in the Hang-zhou Bay. Different schemes of splitting have been devised and compared.Results of the study indicate that good simulation can be achieved. Besides being simpler in form, this method is flexible and allows much freedom in selecting the mode of splitting and the scheme of computation.

基于二次散射的水污染遥感模型及其在珠江口水域的应用

根据水中悬浮物、污染物和水分子等的散射和吸收物理机制建模是实现水污染定量遥感的有效途径.基于一次散射的水污染遥感模型简单易行,但在浑浊度较大时其精度不高.在基于一次散射模型的基础上分析了多次散射的能量组成特点,提出再考虑二次散射可使模型的精度显著提高且不至于使模型过于复杂;导出了二次散射的补偿因子,同时给出了考虑二次散射因子的简单计算方法.将该模型应用于珠江口水域的水污染遥感的结果表明,较之基于一次散射的模型,考虑二次散射的水污染遥感模型在精度上有明显改进.遥感提取结果显示,珠江口水域重污染区主要分布在伶仃洋东北部,香港维多利亚港和深圳湾.
