冰心中的气候环境记录与全球变化研究

冰心是高分辨地记录全球变化的主要信息载体之一。本文总结了冰心中提取古气候和古环境信息的系列记录，包括同位素、微量气体、阴阳离子、微粒、生物和有机质等。着重讨论了由这些记录提取的古气候和古环境变化方面的研究进展，并提出了今后的研究重点。     

北仑港区宁波组晚大理冰期气候特征

以往认为宁波组沉积时期的古气候为寒冷干燥或冷凉干燥。本文依据北仑B_(12)孔的孢粉资料,阐明在这一冷期中曾有一次相对较暖的气候波动,据此又可分冷凉—温和—温凉三个阶段,湿度以略湿为主。此外,还讨论了本区在晚大理冰期温度、湿度的变化特点。     

Geographical distribution of fish catches and temperature variations in the northeast Atlantic since 1945

Warming of the northeast Atlantic is expected to affect the location and productivity of fish stocks. It is examined whether variations in catches of cod, herring, mackerel, anchovy and sardines in the ICES statistical areas are related to variations in ocean temperature. Temperatures at certain locations along the Norwegian coast are taken as proxies for temperatures in the Norwegian Sea and the North Sea. It is found that the catches of cod in the North Sea are inversely correlated with temperature and that recruitment and catches of cod in the Norwegian Sea and the Barents Sea are positively related to temperature. There is also some indication of a positive correlation between temperature and the catches of mackerel in the North Sea and the Norwegian Sea, and between temperature and the catches of sardines in the North Sea.     

地质环境特征及工程适应性与选择性分析——青岛市城市地质环境研究

根据地形地貌、地质构造、水文地质条件将青岛市划分为６个工程地质亚区，论述了各亚区地质环境特征，结合不同城市建筑工程特点，进行了工程场地适应性和选择性分析评价，为充分合理利用城市地质环境提供良好依据     

广州在沿海开放城市的旅游形象定位研究

根据国际形象设计发展趋势,提出城市旅游形象设计应有３个层次：一是城市旅游整体形象;二是城市旅游吸引物的特色形象;三是旅游企业形象。根据Ｊｅｎｓｅｎ－Ｖｅｒｂｅｋｅ都市旅游产品界定模式,结合广州实际,分析了广州的旅游吸引物,将广州旅游形象定位为（１）商都旅游,包括购物,美食、商务旅游和现代化城市景观的游览;（２）近现代史迹旅游,包括古代史迹和建筑艺术的观赏,其形象口号为“两个中心”,即商贸中心和近现     

加入WTO对中国旅游业的影响及应对措施

加入WTO必然对中国旅游业的发展产生重大影响，既包括创造机遇，也包括提出挑战。对此，应采取加快体制改革、留住高素质的旅游经营管理与服务人才、积极学习和借鉴国际旅游业先进的经营管理模式和经验、适时调整旅游业的产业对策，宣传中华民族文化、抓住奥运旅游的机遇，创造中国旅游的新品牌等应对措施，使得中国旅游业步入按国际惯例办事的轨道。     

新世纪大洋钻探"三角鼎立"中的欧洲联合体

欧洲为了与美国、日本在IODP中处于同等重要的地位，成立了由ODP成员参加的欧洲大洋钻探科学指导委员会（ESCOD）和JEODI组织，并开展了IODP之前的一系列准备活动。在其中的APLACON会议上，论证了IODP中第三类特定钻探平台的必要性，讨论了该类平台在某些研究范围内的重要作用，包括研究地球历史中的极端气候（北极海区）、重建白垩纪－第三纪的水文地理学、气候的快速变化、沉积盆地形成与过程以及固体地球过程等。     

海岛旅游效率空间格局演变及影响因素研究 ——以中国12个海岛县(区)为例

旅游产业是海岛地区的重要产业之一，借助 DEA 模型测度 12 个海岛县 （区） 的旅游效率，采用组合方法对海岛旅游效率的空间特征演变进行刻画，并通过 EVIEWS 软件分析海岛旅游效率的影响因素。 （1） 海岛旅游综合效率总体不高，技术效率是海岛旅游效率发展的主要驱动力，规模效率水平较低，海岛旅游发展能力未得到全面发挥。 （2） 海岛县 （区） 之间旅游效率总体差异不大，相对差异明显。海岛旅游效率空间状态演变由不稳定趋向于稳定，可能存在“贫困陷阱”和“俱乐部趋同”现象。 （3） 经济发展水平、生态环境、科技信息对海岛旅游效率的发展起到积极的推动作用，产业结构、交通条件、城镇化是海岛旅游效率发展的约束性因素。     

Subsurface Water Masses in the Central North Pacific Transition Region: The Repeat Section along the 18° Meridian

A repeat hydrographic section has been maintained over two decades along the 180° meridian across the subarctic-subtropical transition region. The section is naturally divided into at least three distinct zones. In the Subarctic Zone north of 46°N, the permanent halocline dominates the density stratification, supporting a subsurface temperature minimum (STM). The Subarctic Frontal Zone (SFZ) between 42°–46°N is the region where the subarctic halocline outcrops. To the south is the Subtropical Zone, where the permanent thermocline dominates the density stratification, containing a pycnostad of North Pacific Central Mode Water (CMW). The STM water colder than 4°C in the Subarctic Zone is originated in the winter mixed layer of the Bering Sea. The temporal variation of its core temperature lags 12–16 months behind the variations of both the winter sea surface temperature (SST) and the summer STM temperature in the Bering Sea, suggesting that the thermal anomalies imposed on the STM water by wintertime air-sea interaction in the Bering Sea spread over the western subarctic gyre, reaching the 180° meridian within a year or so. The CMW in this section originates in the winter mixed layer near the northern edge of the Subtropical Zone between 160°E and 180°. The CMW properties changed abruptly from 1988 to 1989; its temperature and salinity increased and its potential density decreased. It is argued that these changes were caused by the climate regime shift in 1988/1989 characterized by weakening of the Aleutian Low and the westerlies and increase in the SST in the subarctic-subtropical transition region.
