华南全新世高海滩岩与海岸大震构造

笔者在世界上首次发现的华南海岸全新世高海滩岩中，又发现了海滩岩断代序列模式及其中蕴藏的重大科学信息。本文重点讨论高海滩岩与闽粤琼大震、大震构造与地震周期序列的关系，以及大震构造的定量标志。此外，继发现２５０年左右阶段的海岸升降年垂直活动速率后，又发现了５０年左右阶段的年活动速率。     

渤,黄海冬季强冷空气智能预报决策系统

冬季强冷空气造成的大风对海上船只影响较大，所以对于强冷空气影响的时间和强度的预报至为重要。本文借鉴了决策支持系统的研制方法，建立了渤、黄海冬季强冷空气智能预报决策系统。该系统拥有数据库及其管理系统、模型库及其管理系统、知识库和内部通讯系统；该系统采用了定量预报加定性分析的方法，把数学模型与预报员的经验有机地结合到一起。     

1994年西太平洋副高异常的前期特征分析

本文通过相关普查，分析了影响夏季西太平洋副热带高压的北太平洋海温场和北半球５００ｈＰａ高度场的前期特征，找出了影响１９９４夏季酉太平洋副热带高压异常的强信号及其所在区域．以较高的信度和精度建立了夏季逐月副高强度和脊线位置两特征量的预报方程，进一步发现，中、东部太平洋海温场存在与副高强度高相关的对偶相关区，该区同前一年６月加利福尼亚寒流和北赤道暖流间形成的海温梯度相对应，而初夏副高脊线位置则决定于前一年１０～１２月赤道东太平洋一线的海温分布．

Relating hydrograph components to rainfall and streamflow: a case study from northern Taiwan

Abstract

This study investigates the characteristics of hydrograph components from a watershed in Taiwan. Hydrograph components were modelled by using a model of three serial reservoirs with one parallel reservoir. Mean rainfall was calculated by using the block kriging method. The model parameters for 38 events were calibrated by using the shuffled complex evolution optimization algorithm. The model verification was made using 18 events. Based on the study results, the following findings were obtained: (1) for single-peak events, times to peak of hydrograph components are an increasing power function of the peak time of rainfall; (2) peak discharges of hydrograph components are linearly proportional to that of total runoff, and the ratios of quick and slow runoff are approximately 83% and 17% of total runoff, respectively; and (3) the total volume of quick runoff component is 52% of total runoff and that of slow runoff is 27%.

公益性油气基础地质调查的进展与发展方向

在我国油气资源对外依存度不断攀升,能源安全形势日益严峻的背景下,油气调查评价和勘探开发仍是能源工作的重中之重.近年来,公益性油气调查工作聚焦自身优势,积极服务于国家能源安全,支撑油气资源管理与矿权体制改革成效显著,在油气勘探的新区、新层、新类型方面不断取得突破性成果.公益性油气调查在新疆塔里木盆地西北部温宿凸起新近系、沙井子构造带志留系,准噶尔盆地南缘的二叠系和三叠系均获得了工业油(气)流;在南方鄂西宜昌、黔北武陵山等复杂构造区的页岩气、松辽盆地的页岩油、四川盆地南部煤层气等资源的勘探均取得了重大突破,这些成果有力带动了能源企业的积极投入与勘探,有效彰显了公益性油气地质调查的引领和示范作用.深层油气资源的安全勘探、油气矿权空白区的基础地质调查及非常规油气的调查与勘探将是我国未来油气勘探重要的接替领域.公益性油气调查将以油气基础地质问题为抓手,积极探索油气勘探接替领域,为油气资源规划和管理做好支撑,力争为国家能源安全保障与重大发展战略做出更大的贡献.     

A review of comminution age method and its potential application in the East China Sea to constrain the time scale of sediment source-to-sink process

The East China Sea(ECS) is a river-dominated epicontinental sea, linking the Asian continent to the northwestern Pacific via the large rivers originating from Tibetan Plateau. The relevant huge influx of riverine detritus has developed unique sedimentary systems in the ECS during the Quaternary, offering ideal terrestrial archives for reconstructing Quaternary paleoenvironmental changes and studying land-sea interactions. Overall, two characteristic river systems dominate the sedimentary systems and sediment source to sink transport patterns in the ECS, represented by the Changjiang(Yangtze River) and Huanghe(Yellow River) for the large river system and Taiwan rivers for the small river system. Given this, the sediments derived from both river systems bear distinct features in terms of parent rock lithology, provenance weathering and sediment transport. Previous studies mostly focus on either the ‘source' discrimination or the ‘sink' records of the sedimentary system in the ECS, while the source to sink process linking the land and sea, in particular its time scale, has been poorly understood. Here we introduce a newly-developed dating technique, the ‘comminution age' method, which offers a quantitative constraint on the time scale of sediment transfer from its ultimate source to the final depositional sink. This novel method is of great significance for improving our understanding on the earth surface processes including tectonic-climate driven weathering, and sediment recycling in relation to landscape evolution and marine environmental changes. The application of comminution age method in the ECS will provide important constraints on sediment source-to-sink process and more evidences for the construction of late Quaternary paleoenvironmental changes under these unique sedimentary systems.
