埕岛油田海上石油平台基础冲刷研究

海洋石油平台的建立会改变平台周围的水动力条件，其中平台的基础及与之连接的海底管缆(输油管道、注水管道、海底电缆等)附近产生冲刷现象，对平台和海底管缆的安全造成威胁。根据对研究区典型平台的4次实洲水深并结合以往资料，分析了埕岛油田海上石油平台基础冲刷的过程及其规律。     

涠洲岛珊瑚礁生态系中浮游动植物与环境因子关系的初步探讨

本文根据1990年4月、10月间的理化分析数据，结合2002年9月涠洲岛珊瑚礁生态环境的调查状况，首次从珊瑚礁生态系的角度初步探讨该岛区浮游动植物与环境因子的关系。结果表明：该岛区浮游动植物的分布具有明显的区域性和季节性，既体现了珊瑚礁生态系具有较高的初级生产力特征，也体现了浮游动植物具有显著的季节交替现象。相关分析显示，水温、盐度、N，P，Si营养盐对浮游植物的种类组成及数量变动均有明显影响，但对浮游动物的影响不大；N是该生态系中浮游植物的限制因子，P限制状况只有在珊瑚礁生长带较深的海域出现，Si呈相对富足状态。     

南海北缘东部盆地油气资源研究

南海北缘东部的珠江口盆地及台西南盆地蕴藏着十分丰富的油气资源，根据区域构造背景、盆地发育分布的特点及中、新生代的油气地质条件，结合含油气构造、油气田、油气井的分布规律，利用油气资源评价的理论、方法，对区内的油气资源进行了综合研究，并按照油气资源状况划分出油气富集区、油气潜力区、油气远景区，在此基础上，再进一步划分出4条油气富集带、11条油气潜力带、8条油气远景带，充分显示了该区石油、天然气的分布规律和油气地质特点，为商业性的勘探开发和理论研究奠定了基础。

赤道西太平洋大气边界层的诊断分析

利用１９９３年ＥＮＳＯ事件爆发（４月）前酝酿时期“热带大洋与全球大气－海洋耦合响应试验”强化观测阶段“向阳红五号”科学考察船１５５°Ｅ，２°Ｓ定点海洋气象和高空大气探测资料，分析了赤道西太平洋大气边界层特征。结果表明：赤道西太平洋上空辐合对流区边界层内也有等温或逆温层存在，大气边界层物理参数变化与大尺度海－气变异有密切关系，赤道太平洋沃克环流加强、东移，边界层上部逆温层出现概率明显增大，边界层内高湿层湿度减小。另外，边界层内实测风速、风向廓线随高度的变化基本上不服从Ｅｋｍａｎ规律，但由其平均，分量合成得到的平均风随高度的变化却基本符合Ｅｋｍａｎ规律。

使用GAMIT进行高精度基线向量解算的方法与实践

GAM IT是国际上常用的GPS定位定轨软件,但由于其安装的平台(UN IX/LINUX)与我们通用的W indow s平台有所差异,使得GAM IT的入门较难。因此本文结合具体实例,介绍GAM IT的安装、基本操作以及应用GAM IT进行高精度基线向量解算,供初学者参考。     

Summer distribution and geochemical composition of suspended-particulate matter in the east china sea

The distribution and geochemical composition of suspended-particulate matter (SPM) in the East China Sea (ECS) were investigated during the summer period of high continental runoff to elucidate SPM sources, distribution and cross-shelf transport. The spatial variability of SPM distribution (0.3–6.5 mg l⁻¹) and geochemical composition (POC, Al, Si, Fe, Mn, Ca, Mg and K) in the ECS was pronounced during summer when the continental fluxes of freshwater and terrestrial materials were highest during the year. Under the influences of Changjiang runoff, Kuroshio intrusion, surface production and bottom resuspension, the distribution generally showed strong gradients decreasing seaward for both biogenic and lithogenic materials. Particulate organic carbon was enriched in surface water (mean ∼18%) due to the influence of biological productivity, and was diluted by resuspended and/or laterally-transported materials in bottom water (mean 9.4%). The abundance of lithogenic elements (Al, Si, Fe, Mn) increased toward the bottom, and the distribution correlations were highly significant. Particulate CaCO₃ distribution provided evidence that the SPM of the bottom water in the northern part of the study area was likely mixed with sediments originally derived from Huanghe. A distinct benthic nepheloid layer (BNL) was present in all seaward transects of the ECS shelf. Sediment resuspension may be caused by tidal fluctuation and other forcing and be regarded as the principal agent in the formation of BNL. This BNL was likely responsible for the transport of biogenic and lithogenic particles across or along the ECS shelf. Total inventories of SPM, POC and PN are 46, 2.8 and 0.4 Tg, respectively, measured over the total area of 0.45 × 10⁶ km² of the ECS shelf. Their mean residence times are about 27, 13 and 11 days, respectively. The inventory of SPM in the water column was higher in the northernmost and southernmost transects and lower in the middle transects, reflecting the influences of terrestrial inputs from Changjiang and/or resuspended materials from Huanghe deposits in the north and perhaps from Minjiang and/or Taiwan’s rivers in the south. The distribution and transport patterns of SPM and geochemical elements strongly indicate that continental sources and cross-shelf transport modulate ECS particulate matter in summer.

Using benthic macrofauna to assess environmental quality of four intertidal mudflats in Hong Kong and Shenzhen Coast

Abstract-Intertidal zone is a significant wetland between land and ocean. It plays an important rolein maintaining local ecological balance. Both Mai Po and Futian intertidal mudflats are located in Shen-zhen Bay and are important "refueling" point along the East Asian/Australian flyway of migratory birds.The environmental quality of Mai Po and Futian mudflats have aroused great concern due to rapid eco-nomic developments in Hong Kong and Shenzhen in recent decades. Microinfauna of Mai Po and Futianmudflats was investigated in December 2000 and the faunal data were used to assess their environmentalquality. Two other mudflats, namely Ma Wan Typhoon Shelter (a more disturbed area) and Luk Kengintertidal mudflat (a place with relatively less human disturbance), were also sampled for macroinfaunaand used as reference mudflats. Shannon-Weaver species diversity index (I_(sd)), biotic coefficient (C_b)and macrofaunal pollution index (I_(mp)) of the macrofauna community on four intertidal mudflats wereused to
