论我国南海资源的特点及开发利用对策

南海我国可管辖的海域面积近200万km^2，具有丰富的生物，油气，矿产等资源，是我国经济与社会可持续发展的强大支持和保障因素，具有海域面积大，资源丰富，区位优势明显，未来开发潜力大等特点，应从强化“寸海寸金”的海洋国土意识出发，通过创新管理体制和运行机制，建立强有力的海上统一执法队伍，按照统一规划，相对集中，由远及近的原则实施重点区域开发战略，全面提升南海国土资源开发利用的水平和效益。     

蔚蓝色：中华文明的再度辉煌

在数千年的历史长河中，中华民族既有因亲近海洋，在航运及船舶制造、海上贸易、海洋渔业等方面谱写下了壮丽的篇章，创造出了灿烂的海洋文明的辉煌时期，也有过因疏远海洋、丧失了世界文明领先地位，沦为“东亚病夫”而遭受任人崭割的悲惨岁月。回顾过去，展望未来，开发海洋、经略海洋，必将带来中华文明的再度辉煌。     

Foreword

Ocean circulation in the Yellow and East China Seas is very rich in mesoscale phenomena, such as eddies, fronts, upwellings, river plumes, etc. Among others, having drawn tremendous attention from oceanographic community in the past for nearly 50 years are mainly the Yellow Sea Cold Water Mass (YSCWM) and its related circulation, the Yellow Sea Warm Current (YSWC), the East China Sea     

Marine Ingressive Events Recorded in Epicontinental Sequences:Example from the Cretaceous Songliao Basin of NE China in Comparison with the Triassic Central Europe Basin of SW Germany

Songliao Basin is filled predominantly with continental facies sediments including alluvial fan, fluvial plain, fan delta , lacustrine delta, shore ?shallow lacustrine, beach salty flat, semi - deep to deep lacustrine, subaqueous gravity flow, lacustrine swamp and pyroclastic sediments. However, some event units were formed during lake - marine linking periods of the Mid - Cretaceous in the basin, which include black shales with high values for salinity ( Sr/Ba) , alkalinity (Ca Mg)/ (Si Al) , reducibility ( Ni Zn)/Ga and sulfide sulfur as well as heavy isotopes. The Breitenholz ?section to be represen-ted for facies comparison with the Cretaceous evaporitic series in Northeast China is localized in Southwest Germany. Stratig-raphically it belongs to the Crabfeld Formation of Keuper of the Germanic Triassic corresponding to Ladinian - Camian of the international reference scale, and is generally called Lower Gipskeuper. The Germanic Triassic was deposited in the epiconti-nental(cratonic) central Euro     

八十年代英国中学地理教学

八十年代,地理教学在英国学校中占有众所承认的地位,英国学校把地理教学纳入教程的方式因地方教育机构所管理的学校学制不同而异。最普遍的学制是5～11岁的儿童上小学,9—13岁的儿童上中学,这些学校均将地理纳入综合的教学课程中,或做为环境教育的部分内容。     

Life's origin: the cosmic, planetary and biological processes

From elements formed in interstellar furnaces to humans peering back at the stars, the evolution of life has been a long, intricate and perhaps inevitable process. Life as we know it requires a planet orbiting a star at just the right distance so that water can exist in liquid form. It needs a rich supply of chemicals and energy sources. On Earth, the combination of chemistry and energy generated molecules that evolved ways of replicating themselves and of passing information from one generation to the next. Thus, the thread of life began. This chart traces the thread, maintained by DNA molecules for much of its history, as it weaves its way through the primitive oceans, gaining strength and diversity along the way. Organisms eventually moved onto the land, where advanced forms, including humans, ultimately arose. Finally, assisted by a technology of its own making, life has reached back out into space to understand its own origins, to expand into new realms, and to seek other living threads in the cosmos.
