A STUDY ON LOCATION OF TOWNSHIP INDUSTRY IN SHANGHAI SUBURBS

The township industry in Shanghai suburbs has undergone a rapid development in the past few years. Aimed at studying the spatial law of the township industry in Shanghai suburbs, three kinds of indexes including distribution density, economic benefit, and regional structure are selected and analysed using correlation analysis method. There are 12 indexes in total. It is found that the locational variation of the township industry in Shanghai suburbs conforms to the following distribution equation:y=ae-bx (x> 5)The above equation has been more and more conforming to the real distribution of the township industry. It is obvious that decreasing trend from inner suburban districts to outer suburban districts is an important character of the locational variation of the township industry of Shanghai suburbs. The fact is closely related with the radiation intensity of the urban economy and the locational superiority for the development of township industry. The regional strategies of the township industry of S

INDUSTRIAL LINKAGES AND RURAL INDUSTRIALIZATION: A CASE STUDY OF HENAN PROVINCE, CHINA

The fast growth of rural industry in China has generated regional development of large rural areas. What role does industrial linkages play in Chinese rural industrialization? This is a same question as the relation between industrial linkages and regional development which has been discussed for decades and no final conclusion reached. The paper pursues the discussion and focuses on rural areas in China with special reference to Henan Province. On the basis of data from an investigation on nearly 200 industrial enterprises, this study emphasizes that the linkages play a very important role in spreading development of industry in rural areas. It is recommended that the national policies should prompt industrial linkages to upgrade the technological level of rural industry and to integrate rural industry with urban industry.     

日本"中京圈"的可持续发展及其启示--兼论2005年爱知世博会

日本的中京圈和首都圈、关西圈并列被称为具有代表性的三大经济圈。中京圈和首都圈、关西圈相比规模和人口略小，但是以技术密集型工业为主体的产业结构使其在全日本占有举足轻重的地位。战后尤其是以汽车、航空工业为主的运输器械工业得到了空前的发展。进入90年代以来，随着经济全球化和信息化的到来，以重型工业为中心的中京圈迎来了极大的挑战。因此，中京圈在制定产业功能定位、发挥中心区位优势的作用以及基础设施配套建设等方面提出了新的发展规划。2005年在中京圈举行的爱知世博会是21世纪第一个世界博览会。爱知世博会的主题是“自然的睿智”。大会将探讨一些全球性课题的解决方向和可持续发展问题，体现人与自然的和谐。此外，日本也希望通过这些战略性的思考，为中京圈的可持续发展寻找出路。     

全球化背景下武汉城市圈经济发展的思考

以大城市为中心的城市圈域经济是当今世界经济发展的普遍趋势。在经济全球化的新形势下，城市圈域经济的发展与世界经济的宏观环境息息相通。本文在分析了世界经济一体化下区域经济发展的宏观环境条件的前提下，剖析了武汉城市圈经济发展的优势与劣势，并以此为基础提出了武汉城市圈的经济发展思路。     

简评《地质辞典》中的“煤层气”词条

简要评述了《地质辞典》中“煤层气”词条释义方面存在的谬误；指出该词条作者不仅没有给读者任何正确、有用的信息，更为严重的是对煤层气资源工业价值的否定性评价阻碍了我国煤层气的研究、勘探开发进程。因此《地质辞典》再版时，应对煤层气词条进行全面修订，以免继续误导读者。     

大兴安岭北部金矿床类型及地质特征

大兴安岭北部是我国重要的金成矿区之一。区内13处岩金矿床(点)均与中生代岩浆活动有关，形成于中生代(晚侏罗世一早白垩世)。金矿床(点)具有NE成带，NW成行的分布特征。EW、SN和NE向断裂是主要的容矿构造，多组断裂的交汇处是矿化的有利部位。根据区域成矿特点及成矿条件可划分出3种矿床类型，即蚀变岩型、石英脉型和隐爆角砾岩型。成矿物质以深源为主，有部分地壳物质的加入；成矿溶液是岩浆热液和大气降水的混合流体；成矿温度为200-300℃，属中低温热液型金矿床。     

Contrasting stratified plutons exposed in tilt blocks, Eldorado Mountains, Colorado River Rift, NV, USA

Roof-to-floor exposures of mid-Miocene plutons in tilt blocks south of Las Vegas, NV, reveal distinct but strongly contrasting magma chamber statigraphy. The Searchlight and Aztec Wash plutons are well-exposed, stratified intrusions that show a similar broad range in composition from 45–75 wt.% SiO₂. Homogeneous granites that comprise about one-third of each intrusion are virtually identical in texture and elemental and isotopic chemistry. Mafic rocks that are present in both plutons document basaltic input into felsic magma chambers. Isotopic compositions suggest that mafic magmas were derived from enriched lithospheric mantle with minor crustal contamination, whereas more felsic rocks are hybrids that are either juvenile basaltic magma+crustal melt mixtures or products of anatexis of ancient crust+young (Mesozoic or Miocene?) mafic intraplate.

Despite general similarities, the two plutons differ markedly in dimensions and lithologic stratigraphy. The Searchlight pluton is much thicker (10 vs. 3 km) and has thick quartz monzonite zones at its roof and floor that are absent in the Aztec Wash pluton. Isotopic and elemental data from Searchlight pluton suggest that the upper and lower zones are cogenetic with the granite; we interpret the finer grained, slightly more felsic upper zone to represent a downward migrating solidification front and the lower zone to be cumulate. In contrast, the upper part of the Aztec Wash pluton is granite, and a heterogeneous, mafic-rich injection zone with distinct isotopic chemistry forms the lower two-thirds of the intrusion. Similar mafic rocks are relatively sparse in Searchlight pluton and do not appear to have played a central role in construction of the pluton. Large felsic and composite dikes that attest to repeated recharging and intrachamber magma transfer are common in the Aztec Wash pluton but absent in the Searchlight pluton. Thus, although both intrusions were filled by similar magmas and both developed internal stratification, the two intrusions evolved very differently. The distinctions may be attributable to scale and resulting longevity and/or to subtle differences in tectonic setting.     

河西走廊祁连山山前缺水区找水方向

本文根据近20年来在河西走廊从事水文地质工作所掌握的资料，结合前人研究成果，将山地与平原的接触关系归纳为3种类型，每一种类型都具有特定的水文地质条件，它们的共同特点是存在于山体与走廊平原之间的“叠瓦状”大型逆冲隐伏断裂带及其所派生的山麓中新生界皱褶，阻止了山区基岩裂隙水与走廊平原第四系松散岩类孔隙水之间的水力联系，使山林与走廊平原衔接地带地下水位突变，产生100～200m或更深的“地下跌水”，也正是这一原因，使历年来在这一缺水区的地下水勘察变得尤为慎重，正确找水方向在于根据山体与平原的接触关系的不同，因地制宜地开发利用地下水（泉水）资源。
