南京玄武湖浮游细菌群落结构的季节变化及其与环境因子的关系

应用16S rRNA基因末端限制性片段长度多态性技术和多元统计方法,探究了南京玄武湖浮游细菌群落结构的季节性变化,并找出了浮游细菌群落组成分布的主要影响因子.结果表明,玄武湖4个季节中夏季Invsimpson指数、Shannon-Wiener指数和Pielou指数最高,而春季最低.非度量多维尺度分析结果显示浮游细菌群落结构存在着明显的季节性变化.Mantel检验、典范对应分析、变量分割分析表明影响玄武湖细菌群落结构最显著的环境因子为温度,其次为pH.营养盐浓度对玄武湖细菌群落结构的影响不显著.总的来说,本研究将有助于更好地理解富营养化水体中的浮游细菌群落组成的季节变化规律.     

广西南丹县大厂矿田地球物理找矿方法示范

大厂矿田主要矿床的地质特征有其特殊性,即碳质页岩分布极广。以往该矿田的地球物理找矿研究在方法的投入、资料的解释等诸多方面存在不足,导致找矿效果并不理想。文章认为,选择抗干扰能力强、勘探深度大的地球物理新的技术方法,并采用较为先进的定量解释手段,对异常体进行客观的评价,是取得好的找矿效果的关键。研究结果提出,大厂矿田物探找矿应以主动源大功率电磁法及地下物探方法组合的地球物理方法。

Potential and Suitability Evaluation of CO2 Geological Storage in Major Sedimentary Basins of China, and the Demonstration Project in Ordos Basin

From 2010 to 2012, the China Geological Survey Center for Hydrogeology and Environmental Geology Survey (CHEGS) carried out the project “Potential evaluation and demonstration project of CO2 Geological Storage in China”. During this project, we developed an evaluation index system and technical methods for the potential and suitability of CO2 geological storage based on China’s geological conditions, and evaluated the potential and suitability of the primary basins for CO2 geological storage, in order to draw a series of regional scale maps (at a scale of 1:5000000) and develop an atlas of the main sedimentary basins in China. By using these tools, we delineated many potential targets for CO2 storage. We also built techniques and methods for site selection and the exploration and assessment of CO2 geological storage in deep saline aquifers. Furthermore, through cooperation with the China Shenhua Coal to Liquid and Chemical Co., Ltd., we successfully constructed the first coal-based demonstration project for CO2 geological storage in deep saline aquifers in the Yijinhuoluo Banner of Ordos in the Inner Mongolia Autonomous Region, which brought about the basic preliminary theories, techniques, and methods of geological CO2 storage in deep saline aquifers under China’s geological conditions.     

复合生态区划的系统分级及其实证研究

复合生态区划重在揭示不同复合生态地域单元的人类活动和自然环境的相似性与差异性，是进行区域复合生态系统研究的基础工作，对于研究不同复合生态地域单元的发展方向与功能定位具有重要的实践意义。比较分析了复合生态区划与自然区划、生态区划的异同点，简要回顾了自然区划、生态区划的历史演变与应用成效，阐述了复合生态区划的主要原则，提出了生态大区-生态区-生态省-生态地区的四级区划系统及其相应的指标体系与区划方法。根据复合生态系统结构特征及其生态服务功能定位的相似性与差异性，突出人工生态系统和社会文化要素的地位和作用，将四川省划分为2个生态大区、3个生态区、4个生态省和9个生态地区，该区划方案对于制订四川省的生态功能分区具有重要的参考价值，也可以有效地指导四川省的资源开发、产业结构调整和生态环境保护。

水煤气大数据在芜湖社会化管理中的应用

人房基础数据的准确性是社会网格化管理工作的一项重要依据.在传统网格化的管理模式下,网格员需要挨家挨户走访才能掌握管辖区域内的人口变化,针对性不强,信息滞后,工作量巨大.为了解决这一问题,芜湖市社会服务管理网格化平台创造性地引入水煤气大数据分析来研判预测人口变化,为网格员核查人房数据提供重要的"情报"支持.水煤气大数据分析以户为单位对户内用水、用气能耗数据进行自动化分析,同时引入季节性差异补偿参数,建立户内人口居住变化推测模型,提取出需核查的住户数据.以核查任务的形式发送到移动终端App——"社管通",网格员通过社管通核查任务有针对性地进行上门核查.本文提出的水煤气大数据分析解决方案体现了大数据的价值,改变了传统定期全面核查模式,建立了精准靶向核查的工作模式,对保障社管网格内"底数清,情况明"具有重要意义.

The Yudomian of Siberia,Vendian and Ediacaran systems of the International stratigraphic scale

In Russia, the terminal Neoproterozoic formally includes the Vendian of western part of the East European platform and the concurrent Yudoma Group of Siberia. As is shown in this work, the designated subdivisions correspond in the stratotypes only to the upper, Yudomian Series of the Vendian. In the Siberian platform, the Ust-Yudoma and Aim horizons of the Yudomian are tightly interrelated. The lower of them, bearing remains of Ediacaran Fauna, represents the Ediacarian Stage, whereas the upper one containing small-shelled fossils (SSF) corresponds to the Nemakit-Daldynian Stage divided into the trisulcatus and antiqua superregional zones. In more complete sections of the platform periphery, sediments of these subdivisions conformably rest on siliciclastic succession that should be ranked as basal subdivision of the Yudomian. The succession is concurrent to the Laplandian Stage of the East European platform. According to geochronological dates obtained recently, the Yudomian Series spans interval of 600–540 Ma. In the East European platform, the Upper Vendian (Yudomian) begins with the Laplandian basal tillites of synonymous stage. In the west of the platform, tillites are dated at 600 Ma like the Upper Vendian base in Siberia. The next Ediacarian Stage of the East European platform is stratigraphic equivalent of the Redkino Horizon, while summary range of the Kotlin and Rovno horizons is concurrent to that of the Nemakit-Daldynian Stage. The Vendian of Russia is conformably overlain by the Tommotian Stage of the Lower Cambrian. Intense pre-Vendian events constrained distribution areas of the Lower Vendian sediments in Russia. The Lower Vendian deposits of the East European platform are most representative and well studied in the central Urals, where they are attributed to the Serebryanka Group. In Siberia, separate subdivisions representing the Lower Vendian are the Maastakh Formation of the Olenek Uplift, two lower members of the Ushakovka Formation in the Baikal region, and the Taseeva Group of the Yenisei Range. Chronological interval of the Lower Vendian corresponds to 650–600 Ma. The Marinoan Glaciation dated in Australia at 650–635 Ma is concurrent to basal part of the pre-Yudomian interval of the Vendian in Russia, whereas the Laplandian Tillite and Gaskiers Glaciation (600–580 Ma) correspond to onset of the Yudomian Epoch. The new Ediacaran System (Knoll et al., 2004) legalized in the International Neoproterozoic scale is close in range to the entire Vendian (635–544 Ma), although without basal beds (Marinoan Tillite) it deprives the terminal Neoproterozoic of its original sense. Inferiority of the system consists also in its indivisibility into stages. Hence, it is clear that the Vendian System subdivided in detail in Russia should be retained in the rank of terminal system of the Precambrian, one of the basic in general scale of the Neoproterozoic.
