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。     

Numerical modeling of long waves in shallow water using Incremental Differential Quadrature Method

Incremental Differential Quadrature Method (IDQM) as a rapid and accurate method for numerical simulation of Nonlinear Shallow Water (NLSW) waves is employed. To the best of authors’ knowledge, this is the first endeavor to exploit DQM in coastal hydraulics. The one-dimensional NLSW equations and related boundary conditions are discretized in space and temporal directions by DQM rules and the resulting system of equations are used to compute the state variables in the entire computational domain. It was found that the splitting of total simulation time into a number of smaller time increments, could significantly enhance the performance of the proposed method. Furthermore, results of this study show two main advantages for IDQM compared with other conventional methods, namely; unconditional stability and minimal computational effort. Indeed, using IDQM, one can use a few grid points (in spatial or time direction) without imposing any stability condition on the time step to obtain an accurate convergent solution.

南麂列岛潮间带环境本底调查

本文系根据１９９２年８月和１９９３年２月（夏、冬两季）对南麂列岛潮间带的环境本底调查以及对水质、底质、生物样监测结果的资料整理而成。调查结果表明，潮间带水质、底质除个别断面外，均处于良好状态。生物体重金属残留量全部低于全国海岸带调查时统一的标准，生态环境条件较好。

Water mass formation variability in the intermediate layer of the east sea

Long-term variability in the intermediate layer of the eastern Japan Basin has been investigated to understand the variability of water mass formation in the East Sea. The simultaneous decrease of temperature at shallower depths and oxygen increasing at deeper depths in the intermediate layer took place in the late 1960’s and the mid-1980’s. Records of winter sea surface temperatures and air temperatures showed that there were cold winters that persisted for several years during those periods. Therefore, it was assumed that a large amount of newly-formed water was supplied to the intermediate layer during those cold winters. Close analysis suggests that the formation of the Upper Portion of Proper Water occurred in the late 1960’s and the Central Water in the mid-1980’s.

台湾海峡南部灯光围网捕捞的水温选择及其季节变化

对1989－1998年台湾海峡南部渔场生产记录资料分析结果表明：灯光围网捕捞主要捕捞年适宜水温16．1－30℃，年较佳水温20．1－30℃，年最佳选择水温21．2－29℃。环境水温过高或过低，不利于灯光围网生产。各季度的选择水温，冬季为21．2－24℃，春季为21．1－27℃，夏季为26．1－29℃，秋季为25．1－28℃；各月选择水温为该月环境水温的中间值至偏高2℃，多数比中间值偏高1－2℃。选择水温范围的宽幅3－5℃；随环境水温升高或降低，鱼类对水温选择发生同的、同步的变化，是一种渐进的过程；在环境水温上升或持续高温，温跃层存在、底层低温涌升水强盛的条件下，灯光围网的作业效率均受影响。
