南方丝绸之路对大理的影响及当前的对策

大理历史悠久,文化灿烂,风光秀丽,古道纵横。过去南方丝绸之路对大理的经济、政治、交通、文化、宗教等有较大的影响,今天在国家"一带一路"的大战略背景下,大理应该怎么办,大理学院应该怎么办,这是当代学人的新课题。以古代南方丝绸之路为出发点,建议今天大理的"一带一路"定位为交往之路、人情之路。

华南黑色岩系铂多金属矿成矿流体地球化学及其矿床成因意义

较系统的流体包裹体观测显示:①华南黑色岩系铂多金属矿中存在两种不同体系的流体包裹体,一为具中低盐度、NaCl-H2O体系者(Ⅰ型);二为具中高盐度、CaCl2-NaCl-H2O体系者(Ⅱ型);其中后者为该类矿床中首次确定;②存在2个不同期次的成矿流体,其中铂多金属矿层和其下伏磷块岩中碳酸盐石英网脉的流体包裹体特征基本一致,可能代表主成矿期流体,其均一温度峰值为170℃左右,而盐度具双峰式特征,峰值分别为27%～31%和4%～6%;矿层之上碳酸盐石英脉中流体包裹体可能代表了晚期成矿流体,其均一温度多为130～170℃左右,盐度峰值在12%～14%;③在早寒武世,接受了巨厚沉积的扬子克拉通南缘加里东冒地槽中的盆地热卤水受挤压而顺层侧向迁移,从地层中汲取Ni、Mo、V和PGE等成矿元素,形成中高盐度的CaCl2-NaCl-H2O体系成矿热液,沿断裂上升并与NaCl-H2O体系海水混合,形成黑色岩系中的铂多金属矿床(点).     

南宋雅词之探

雅俗之辨是中国古代文学史上一个争议颇多的话题。宋词作为一代文学样式，在雅俗的演变上更有其特点。南宋词坛经过自北宋以来的长期探索与辨析，在词的雅化之路上逐渐形成了自己的理论。内容上反对淫艳猥亵，提倡骚雅；风格上“涉谐谑”、“鄙俗”、“侧艳”则去之；在词体源头的探求上，认为诗词同源，推尊词体；语言和音律求雅，反对俚俗。姜夔、张炎、王沂孙等是南宋雅词的代表。通过南宋词学的雅俗之辨，词的创作发生了根本变化，词人的创作规范化、理性化了，人们认可了词这种文学体裁，并使词体定型，渐成为与诗比肩的一种文体。

Response of the northwestern Pacific upper water δ~(13)C to the last deglacial ventilation of the deep Southern Ocean

The deglacial δ~13C minimum events that originated from the ventilation of the deep Southern Ocean around Antarctica, have been recorded in a range of marine sediments from the southern to tropical oceans in late Pleistocene. However, the broad δ~13C minimum event was also reported as far as to the northern middle latitudes, in northwestern Pacific marginal sea areas, during the last deglaciation. In the northwestern Pacific, forcing from the northern high latitudes is strongly expressed, while the records of in- fluence from the southern high latitudes are few. The Kuroshio Source Region (KSR) forms a boundary between the northwestern Pacific and the southern, tropical Pacific. So, high-resolution planktonic foraminiferal records in core MD06-3054 from the KSR are well positioned to identify signals from the southern hemisphere in the northwestern Pacific. Planktonic foraminiferal tests from the upper 1030 cm of the core were subject to AMS14C, carbon and oxygen isotopic measurements. A negative excursion was found to occur from about 20.0-6.0 ka BP in δ~13C records of both surface (Globigerinoides ruber) and subsurface (Pulleni- atina obliquiloculata) dwellers, but the overall trends of the two curves have reversed since 26.5 ka BP. Moreover, the δ~13C rec- ord of G. ruber (the surface dweller) shows a robust link to the record of atmospheric CO2, and its changes precede the records of P. obliquiloculata (the subsurface dweller). According to the hydrologic conditions, the broad δ~13C minimum event recorded in the KSR is also a response to the increasing ventilation of the deep Southern Ocean around Antarctica during the last deglaciation. The inconsistency between the records of the surface and subsurface dwellers was possibly caused by the ways that the low δ~13C signal was transmitted. Subsurface water primarily received the low δ~13C signal from the Antarctic Intermediate Water (AAIW), whereas the surface water was probably mainly impacted by atmospheric CO2 in the KSR. The records from the KSR confirm the deduction that the broad δ~13C minimum event in the Okinawa Trough was due to the impact of tropical Pacific surface water dur- ing the last deglaciation, and suggest that signals from the southern high latitudes also can be delivered to the northern middle latitudes.     

江苏省人均粮食地域格局变化特征及其驱动力研究

应用GIS技术和空间自相关分析方法,探讨了1995年以来江苏省县域尺度人均粮食地域格局变化特征及粮食生产与经济发展的空间匹配格局,初步分析了粮食生产地域格局变化的驱动因素.结果表明:县域人均粮食存在显著的空间自相关特征,高高聚集和低低聚集趋势增强,全省粮食生产在经济发展相对滞后的洪泽湖流域、里下河地区和沿海农业区中部得到加强,而逐渐从经济发达的苏锡常地区退出;县域经济发展和粮食生产的地域格局呈现出日益显著的空间差异化特征;县域经济发展和政策导向是人均粮食地域格局变化的重要驱动因素,农业自然地理条件对粮食生产布局的决定性作用已有所减弱,在土地和劳动力等资源的比较优势利用基础上形成的社会经济发展综合驱动力对粮食生产布局产生着日益显著的影响.图4,参21.     

The non-marine Crustacea of Antarctica and the Islands of the Southern Ocean: biodiversity and biogeography

A total of 101 verified species and eight ordinal taxa represent the non-marine Crustacea on Antarctica and the islands of the Southern Ocean. The largely terrestrial Isopoda and Amphipoda are confined to some sub-Antarctic and cool temperate islands while the predominantly freshwater Anostraca, Anomopoda, Copepoda (=Calanoida, Cyclopoida, Harpacticoida) and Ostracoda (Podocopida) occur throughout the region. Holocene sea-level rises fragmented freshwater and terrestrial species ranges on New Zealand, Auckland, Campbell, and possibly other South Pacific islands, leaving a legacy of vicariant taxa. Tertiary species probably survived Pleistocene glaciation in aquatic refugia on the New Zealand/South Pacific, Falkland, Crozet and Kerguelen archipelagoes, but there are no valid records of Tertiary Antarctic Crustacea. All 40 Continental and Maritime Antarctic freshwater records can be ascribed to the historic introduction of anthropogenic aliens, Holocene immigration of colonists, returning re-colonists and marine species 'marooned' in epishelf and other coastal lakes.     

Biodiversity and biogeography of non-marine Mollusca on the islands of the Southern Ocean

There are no terrestrial and freshwater molluscs associated with Continental nor Maritime Antarctica. The malacofaunas of the cool-temperate and sub-Antarctic islands of the Southern Ocean are extremely depauperate, comprising a mere 68 site-records of 51 species from 27 genera in 13 families. The South Atlantic records are confined to the Falkland Islands, which harbour nine species (one bivalve, five pond snails and three terrestrial aliens), and South Georgia, where there is one Notodiscus sp. (Charopidae). The fauna of the South Indian Ocean islands of Prince Edward, Crozet, Kerguelen and Heard, comprises two alien slugs and endemic Notodiscus hookeri (Charopidae). The majority of species occur on the South Pacific Ocean Islands of Macquarie, Campbell, Auckland, Snares, Antipodes, Bounty and Chatham to the south and east of New Zealand. The Chatham fauna is dissimilar to that on the other South Pacific Islands, though both represent vicariant remnants of common South Pacific Is./New Zealand Athoracophoridae, Charopidae and Punctidae. There is, other than the broad South Indian Ocean distribution of Notodiscus hookeri, little evidence of Holocene dispersal and colonization. Indeed the Southern Ocean is an effective barrier and the different regional (South Atlantic/Indian/Pacific) faunas are principally vicariant and derived from local survivors of Pleistocene glaciation.
