正Salt Lake is one of the lakes in the system,consisting of a huge amount of salt and bitter-salty lakes in Novosibirsk Oblast and Altai Krai.These lakes are unique and highly unstable systems where the parameters of geochemical     

Brussels: Five capitals in search of a place. The citizens, the planners and the functions

The paper describes the different capital city functions that are accomodated in Brussels. There are in fact five different capitals in Brussels in search of a place. Their locations are conditioned by Brussels' eventful history. The analysis subsequently focuses on the rather negative relation between the local public intellectuals and the city's European capital functions. The location of the European headquarters within the existing urban fabric – unlike Luxemburg and Strasbourg – has caused residential expulsion and further confrontations with the local community during all expansions.Brussels has the most politically decisive institutions. The competition with Luxemburg and Strasbourg has in the past given rise to dubious building processes and hidden agendas regarding the further construction of the necessary space for Europe.Unlike most other capitals Brussels has a low degree of esteem from its citizens. The After-May 68- Movement reacting initially against the CIAM-realisations during the 1970s, continues its activities up until today against two highly symbolic projects: the North Station area called the Manhattan Quarter and the European Headquarters. The movement launched the term Brusselization on the international forum and continues to promote the negative image of its city – notwithstanding the complete change of the official urban planning.The article is a plea for the integration of the actual one-sided advocacy planning within a more comprehensive urban planning approach where strong and soft functions are more in balance. This can also improve the quality of the new European campus now under consideration to accomodate the entry of the East European states in the Union.     

北极斯瓦尔巴特群岛及邻区天然气水合物分解对气候、海洋环境和生物的影响

天然气水合物是一种潜在的巨量能源,但其分解释放的甲烷可能对全球气候与海洋环境产生巨大影响。然而,人们目前对天然气水合物分解产生的环境和生物效应的了解还不够全面。北极地区的斯瓦尔巴特群岛及邻区的海底和冻土层中蕴含大量甲烷,对气候变化十分敏感,是人们研究天然气水合物对气候变化的响应机制和其分解对生态环境影响的绝佳场所。系统总结了斯瓦尔巴特群岛及邻区水合物分解的气候与环境效应,发现目前研究区水合物分解产生的甲烷进入大气的年际通量不大,对全球气候的影响可能有限;水合物分解对海底滑坡起到催化剂的作用,但不是首要因素;海底水合物分解释放的甲烷能打破原有的化学平衡、生产力分布规律与输送机制、生物耦合关系甚至不同栖息地间的连通性,进而影响底栖生物群落。这些认识对研究天然气水合物开采对生态环境可能造成的影响和采取相应防治措施具有一定的借鉴意义。     

A political-cultural map of Europe. Family structures and the origins of differences between national political cultures in the European Union

Differences between the national political cultures of the European states are puzzling. They are too often taken for granted or treated as an elusive explanation for residual differences that can not be accounted for in comparative politics. Here they are put at the core of a comparative analysis. This article explores the origins of differences between national political cultures. It deals with national political cultures from the perspective of Cultural Theory or grid-group analysis. A national political culture is conceived as a ‘conversation’ between subcultures associated to national political institutions and practices (and not as an aggregated pattern of individual orientations toward political objects). National political cultures can be characterised on the basis of ideal typical patterns of relations between the basic cultures or rationalities distinguished by Cultural Theory. After an assessment of the differences between the national political cultures of the Member States of the European Union, the paper considers traditional family structures as possible sources of differentiation, elaborating upon the work of the French political historian Emmanuel Todd who has documented the correspondence between the geography of traditional family structures and the geography of ideologies in Europe. This revised version was published online in August 2006 with corrections to the Cover Date.     

Quantifying Storm Tide Risk in Cairns

The United Nations International Decade for Natural Disaster Reduction (IDNDR)gave rise to an increasing level of attention to the risks posed by a range of naturalhazards and the development of strategies by which to reduce those risks. It waswidely recognised that in order to evaluate risk treatment strategies it was necessaryto `measure' the level of risk that already existed and the level of risk that would beencountered with the treatment strategy(s) in place.This paper outlines the methodology developed under the AGSO (now GeoscienceAustralia) Cities Project to quantify the risk associated with storm tide inundation. It includes the methodology for `measuring' the level of community exposure to storm tide hazards and the methodology for `measuring' community vulnerability. The Far North Queensland city of Cairns is used as the case study to demonstrate the application of these methods.     

Growth Dynamics of the Middle Devonian Jukoupu Bioherm,Xinshao, Hunan

The growth process, palaeoecological features and the function of organisms in reef-building of the Jukoupu bioherm in Hunan are discussed in detail. The bioherm is divided into 10 microfacies. Organisms are very abundant in the reef. Thirty-two genera Belonging to 7 phyla have been recognized. They make up 5 communities composed mainly of stromatopoids, Corals and algae, each of which has its own salient ecological features. An analysis of all communities shows that the organic functions are very complex. The same organisms may possess diverse functions simultaneously as the reef growth enters the late stage. The growth process of the reef may involve five stages' (l)biostrome stage, (2) stabilization stage, (3) frame-type reef-building stage, (4) binding and covering-type reef-building stage, and (5) baffle- type reef -building stage.     

Can dynamite-blasted reefs recover? A novel, low-tech approach to stimulating natural recovery in fish and coral populations

Throughout Southeast Asia, blast fishing creates persistent rubble fields with low coral cover and depauperate fish communities. We stabilized a 20-year-old rubble field in a Marine Protected Area in the Philippines, using plastic mesh and rock piles in replicated 17.5m(2) plots, thereby increasing topographic complexity, fish habitat, and recruitment substrate surface area. Multivariate analysis revealed fish community shifts within the rehabilitated area from that characteristic of rubble fields to one similar to the adjacent healthy reef within three years, as measured by changes in fish abundance and body size. Coral recruitment and percent cover increased over time, with 63.5% recruit survivorship within plots, compared with 6% on rubble. Our low-cost approach created a stable substrate favoring natural recovery processes. Both rehabilitation and the elimination of poaching were integral to success, emphasizing the synergism between the two and the need to incorporate both when considering mitigation.     

M L Determination for Local and Regional Events Using a Sparse Network in Southwestern Germany

A method for the determination of consistent local magnitude M _L values (Richter scale, or M _WA) for earthquakes with epicentral distances ranging from 10 km through 1000 km is demonstrated. The raw data consists of nearly 1300 amplitude readings from a network of six digital seismographs in Baden–Württemberg (Southwestern Germany) during 26 months starting in 1995, later extended by another 1000 amplitude readings until 1999. Relying on most of the basics introduced by C.F. Richter a three-parameter attenuation curve (distance correction, magnitude-distance relation) for Baden–Württemberg and adjacent areas is presented. Station corrections are evaluated and the attenuation curve is calibrated with respect to other agencies for distances greater than 650 km. Reasonable parametrisations are discussed and meaningful error bars are attributed. Finally, a seventh station is incorporated by means of its station correction alone, without needing to update the attenuation curve.     

BJ-RUC产品在小区供暖供回水温度预报的应用研究

利用气象部门快速更新的BJ-RUC(Beijing-Rapid UpdateCycle)数值预报系统获得的24 h逐时的室外温度预报资料,应用能量平衡原理,建立建筑物热损失方程和供热量方程,从而推导出室外温度和室内温度、供水、回水温度的预报模型。用此模型对2010年3月1—15日期间的供、回水温度进行预报模拟,与北京市海园物业供热单位实况值进行对比分析。检验结果表明,该模型模拟的室内温度与设计要求的室内温度(20℃)之间的均方根误差为0.25℃,海园物业室内温度监测点数值与20℃之间的均方根误差为1.53℃。模拟的供、回水温度与海园物业监测点供水温度的均方根误差分别为3.69℃和3.80℃。
