珍惜拥有--SARS后的反思

倘若说“9·11”事件构成了对西方世界的沉重打击的话,那么2003年春夏之交的SARS则构成了对东方世界的沉重打击。这打击带来的沉重气氛,虽然已过去几个月了,但至今想来,仍让国人刻骨铭心。 中国新一届政府面临了考验,每一个中国人都面临了考验。 面对瘟神,举国上下紧紧团结在党中央周围,万众一心,众志成城,与SARS展开了殊死博斗。 危机暴露出旧模式中的弊端,渲染着改革的迫切性。 阳光总在风雨后。痛定思痛,让人震颤,让人了悟。     

BORDER PORT MANZHOULh URBAN FUNCTION AND SPACE DEVELOPMENT

Manzhouli is the largest land port city on the Sino-Russia border, transit cargo through the land port amount-ed to 5.95 million tons, transit tourists were 304 500 in 2000. It stands at the joint place of China, Mongolia and Russi-a, faces to Siberia area of Russia, receives direct support from the Northeast China and Bohai Sea Rim Area, and possess-es priorities in geographical location, land port infrastructure, water resources, coal resources, tourist resources andgreat potentiality in economic cooperation with Russia. The future urban function is a key port on the First Eurasia Continen-tal Bridge. Manzhouli Port will keep its first place between China and Russia land transport, and it is forecasted that thetransit amount through Manzhouli Port will go up to 10 million tons in 2005 and 20 million tons in 2010. It will be construct-ed to be a trade center of the peripheral area extending to Russia and Mongolia, a key export-oriented processing industri-al zone supported by industries such as export processing industries, export agriculture, trade services, technology trad-ing and the other service industries. It keeps being a well-known touring city for trade, shopping, sightseeing, vocation,local food, recreation and cultural events. To build Manzhouli Export Processing Industry Zone will improve city econom-ic structure, and the main sectors are organic food processing, livestock products processing, garment and furniture indus-try. Moreover, Manzhouli Export Processing Industry Zone will eventually be upgraded to be a border free trade zone.The city functional transition will inevitably affect urban spatial restructure and its expansion. The city space transforma-tion will develop as such: one development axis of No. 301 highway paralleling with Bin - Zhou(Harbin - Manzhouli) rail-way which cuts through central part of Manzhouli City, and links Zhalainuocr District with central city; three urban unitsincluding central city, Zhalainuocr District and Manzhouli Interchange Trade Zone; cohesion with Aoerjin and Cuogangpastures; regional dual-nuclei structure of Hailaer City and Manhzouli City; and the Manzhouli-Zabaykalsk Free TradeZone.     

A CASE STUDY ON CONCENTRATION AND DECENTRALIZATION：BEHAVIOR AND DYNAMIC MECHANISM OF SPATIAL EVOLUTION IN METROPOLITAN AREA，NANJING，CHINA

In rapid socio-economic development,the process of concentration and dispersal of various elements tends to be more dramatic,tremendously influencing the shaping and transformation of the space in metropolitan area.Survey of spatial concentration and decentralization has thus become a basic method in examining metropolitan spatial evolution.In this research,three elements were selected as the essential indicators of the process:demographic density distribu-tion,employment density distribution and business office location.Performance of these elements in Nanjing City was exam-ined historically.As Nanjing City could be regarded as a representative of metropolitan areas in China,its situation large-ly suggestes the general characteristics in similar areas of China.Hence based on the investigation of Nanjing City,four general implications were highlighted.First ,metropolitan areas in China are in a violent process and shift of spatial concentra-tion and decentralization.Second,from now to at least the near future,concentration will continue to be the central fea-ture.Third,the landscape of metropolitan areas basically exhibits a dual structure character.The gap in environmental and ecological qualities among different districts will continue for a long time.Fourth,Central Business District (CBD) is playing an important role in helping to convert the traditionally single-centered city structure into a polycentric one.     

大同—阳高Ms6.1地震前兆综合加权信息熵的变化

利用“地震预报计算机专家系统”的思想对大同 -阳高 Ms6 .1地震前每一前兆异常事件进行综合评估 ,以每一异常的最可能发震时间来计算发震概率 ,利用地震前兆综合加权信息熵研究了系统熵值与地震的关系。对华北地区的地震前兆综合加权信息熵研究表明 ,在大同 -阳高 Ms6 .1地震前 ,信息熵出现了明显的减熵有序变化     

红阳煤田石炭-二叠纪含煤地层的沉积特征

红阳煤田含煤地层太原组与山西组,是一套典型的“海陆交互相”沉积。依据剖面上沉积相序列变化特点,可划分为14个沉积旋回,每个沉积旋回均含有一层煤。有二种聚煤环境:一是海水退出潮坪后形成的泥炭沼泽聚积的煤层;二是扇三角洲平原形成的泥炭沼泽聚积的煤层。     

对推进城镇化健康发展问题的思考

城镇化是一个国家和地区经济社会发展的重要标志，也是人类社会走向文明和进步不可逾越的阶段，所谓城镇化（也称城市化、非农化），是指人类生产和生活方式由乡村型向城市型转化的历史进程，表现为乡村人口向城市人口转化以及城市不断发展和完善的过程。城镇化是我国现代化进程中必经的历史阶段。“十五”以来，我国城镇化取得了重要进展，但在加快城镇化发展中也出现了一些偏差。《中共中央关于制定国民经济和社会发展第十一个五年规划的建议》提出，要“坚持大中小城市和小城镇协调发展，提高城镇综合承载能力，按照循序渐进、节约土地、集约发展、合理布局的原则，稳步推进城镇化”。     

城市化进程中土地资源配置的认识误区

按照经济学的观点，城市化就是人口在地理上的集中，一是城市人口的增多，在总人口中的比重上升，二是城市建设规模的扩大，是一个从农村经济转变为具有基本对立特征的城市经济变化过程。这种变化既是人口、市场、企业、基础设施在地理上的集中过程，也是工业化发展引起经济发展的一个必然现象。在这种现象的背后，即工业化各种因素的“集中”特点，最直接的效果就是对土地资源的再配置提出了紧迫的要求。作为认识问题，尤其是对于国家土地资源管理部门来说，消除城市化进程中土地资源配置的认识误区，显得尤为重要。     

中部地区主要城市工业用地的地价杠杆作用

1经济发展和工业用地价格状况 我国经济政策上的中部地区就主要包括山西、河南、湖北、湖南、江西、安徽等6省。中部6省土地面积为102．7万km^2，人口3．63亿，分别占全国的10．7％和28．1％。近年来，在国家政策的大力支持和自身努力下，中部地区城市经济都取得了长足的发展，经济发展同时也带动了土地价格的上涨，但工业用地的价格并没有相应上涨。
