7月份降雨分布型的预报方法

综述了我国７月份雨型的划分方法，各种雨型的多雨特点及环流特征，总结了各类雨型的预报判据，着眼于赤道东太平洋海温（ＳＳＴ），冬季（１－３月）５００ｈＰａ环流，春季（３－５月）西太平洋副热带高压，夏季（６－８月）赤道平流层纬向风准两年振荡（ＱＢＯ）等方面，分析了与７月雨型的关联。该方法对业务预报有很好的指导意义。

Sediment origin and budget in Sepetiba Bay (Brazil) - an approach based on multielemental analysis

 Sediment origin and transport were determined in a shallow 447 km² coastal lagoon in Brazil, using the distribution of major elements in bottom and suspended sediments. Applying multivariate analysis, the sum of normalized concentrations of Ti, Fe, and Al in sediments was selected to trace the terrigenous influence in bottom sediments, whereas Ca, Si, and K were used as indicators of marine influence. Sepetiba Bay bottom sediments are dominated by up to 80% terrigenous inputs. The open bay sediments are enriched in P, Mg, K, and Ca because of the intensive water column primary production. The inner bay forms an independent circulation cell with a predominance of terrigenous sediments. The results suggest a long residence time for particles in the bay, demonstrated by the magnitude of resuspension flux compared to the total sediment input to the bay.

腾格里沙漠东南缘降尘粒度特征和沉积速率

从多年降尘实测资料入手，分析了粉尘粒度特征、沉积速率和时变过程。提出了气象要素相关估测模型．确定０．２５ｍｍ为本区粉尘沉积粒径上限。周围沙漠是粉尘沉积细砂部分的尘源，粉砂和粘土部分沉积来自一个较大的时空范围，二者几乎各占降尘量的１／２。研究区年平均粉尘沉积速率４３５８ｋｇ／ｈｍ２，每年５月的季风转期具有年内最大沉积速率。     

内陆待开发地区产业发展模式探讨——以内蒙古为例

以内蒙古为例，探讨了内陆待开发地区的产业发展模式，内陆待开发地区经济发展的主要制约因素是缺乏资金，缺乏技术，缺乏人才，因此，其经济发展必须有选择，有重点地优先发展部分行业。一般说来，待开发的内陆地区其经济发展必须以资源优势为依托，以市场为导向，开发优质名牌产品，发展优势产业，建设主导产业，带动地区经济的起飞。

华南（东）变质基底特征、古构造型式及铀、金矿化远景

华南（东）变质基底由杨子及华夏两块不同特征的地质体组成，中元古代之后，该地区分别经过了碰撞对接、拉开、再拼贴的演化过程。碰撞对接带和在古裂谷系基础上成型的陆内推覆及平移、剪切型拼贴带构成了本区基底构造主要型式。铀及金矿远景与基底特征关系密切，铀矿主要产于基底裂隆带部位，金则主要产于裂凹（裂陷）带部位。古基底构造交叉部位是中新生代构造活动活跃部位，受其控制的早期横向火山裂谷盆地，在晚期拉张条件下形成的岩浆杂岩带是铀、金、多金属成矿最佳远景区。     

Current controlled sediment deposition from the shelf to the deep ocean: the cenozoic evolution of circulation through the SW pacific gateway

 The circulation of cold, deep water is one of the controlling factors of the Earth's climate. Forty percent of this water enters the world ocean through the Southwest Pacific as a deep western boundary current (DWBC) flowing northwards at bathyal to abyssal depths, east of the New Zealand microcontinent. South of latitude 50°S, the DWBC is intimately linked with the Antarctic circumpolar current (ACC), which is the prominent force for the shallow-water circulation. The Pacific DWBC is presently the largest single contributor of deep ocean water, and deciphering its evolution is of fundamental importance to understanding ocean and climate history, and global ocean hydrography. The evolution of the DWBC system, and of related circum-Antarctic currents, has taken place since 30–25 Ma when plate movements created the first oceanic gaps south of Australia and South America. The stratigraphic record preserved in sediment drifts of the Southwest Pacific, in eastern New Zealand, is the best available for deciphering the Neogene history of Southern Ocean water masses, and of the circulation of the ACC, DWBC and their precursor systems. Major current activity commenced on the New Zealand margin in the late Eocene or early Oligocene (Hoiho Drift; early ACC) and was widespread by the mid-late Oligocene (Marshall Paraconformity and Weka Pass Limestone drift; ACC). During the Neogene the eastern South Island continental shelf built seawards by accretion at its outer edge of large Miocene current drifts up to tens of kilometres long and hundreds of metres thick (Canterbury drifts). Also commencing in the mid-Cenozoic, but in depths >2000 m, the DWBC emplaced large deep-water sediment drifts. Rates of drift deposition accelerated considerably in the late Neogene, when climatic change (and particularly glacial sea-level falls) caused the delivery of large volumes of turbiditic sediment into the path of the DWBC via the Bounty and Hikurangi channels.
