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.     

矿产资源开采中的供地方式

矿山企业是用地大户，往往也是占用耕地、污染环境、破坏生态的大户 　对矿山企业用地实行有偿使用，并由其对占用的耕地进行复垦，对污染的环境进行治理，是用 地制度的一项改革。但这一改革还不尽完善，使矿山企业面临诸多新的矛盾 　如何完善矿产资源开采中的土地供应方式，作者的一些设想颇有见地     

奎屯河山前扇形地的地质灾害分析

奎屯河山前扇形地(简称奎屯扇形地)特有的自然地理条件,存在地震、洪水、泥石流、滑坡、崩塌和尘暴等多种地质灾害,并具有特殊的发生规律和表现形式,本文通过调查研究对地段性的地质灾害活动进行了分析、评价,初步提出有方向性的躲避和有目标性的抗灾.以及主动控制的治理措施.     

景宁县国土资源局 早准备 早部署 有效地组织抗洪

6月18日以来，景宁县普降大暴雨，洪水；中毁道路、房屋、桥梁、电力通讯设备等，造成重大经济损失。截止23日统计，这次洪灾共引发滑坡、崩塌、泥石流等各类地质灾害106起。在这次抗洪中，县国土资源局早准备、早部署，有效地组织抗洪，全局出动抗洪23次59人。县乡村各级干部战斗在抗洪一线，特别是负责地质灾害隐患点的乡镇村干部和国土资源所工作人员高度重视，紧急撤离63个隐患点中的1503人，     

湘西北地区铅锌矿床成矿规律及找矿方向

湘西北地区以盛产层控型低温热卤水铅锌矿床著称。矿床赋存于早寒武世晚期至早奥陶世早期分别受台地边缘相、台前斜坡相和局限台地相控制的碳酸盐地层中。矿体主要呈层状、似层状且具多层性,局部可切层,少数呈脉状。其产出受岩石的原生孔隙和容矿层内构造如虚脱—滑动空间、破碎带及裂隙系统等多因素控制。深大断裂带为主要导矿构造。容矿层不是矿源层,铅锌矿不存在同生沉积特征或痕迹。铅同位素年龄晚于赋矿地层年龄。矿质主要来源于碳酸盐建造以下的一大套碎屑岩建造,部分来自深部和造山带。矿床无围岩蚀变则无铅锌矿化,矿化富集强度与多类型围岩蚀变强度及层内构造空间发育程度呈正相关关系。该地区成矿地质条件优越,在划分出的4个找矿远景区内,许多低工作程度区和找矿空白区里仍具有巨大的找矿潜力,可望找到新的矿床。     

The Lagoon of Venice： geological setting,evolution and land subsidence

The paper deals with the geological setting, history and subsidence of the Venetian Plain. Major attention is paid to the Pleistocene-Holocene stratigraphic sequence in the Lagoon of Venice, in relation to its origin that datesback to 6-7 kyr BP. Geological land subsidence, which played an important role in the origin and the evolution of the lagoon, and anthropogenic subsidence, that has recently assumed a major importance for the Venetian environment, are discussed. Considering also the sealevel rise, 23 cm loss in land elevation has occurred in the last century, leading to increased flooding events and environmental problems that require protective works.
