对“提升基础地质调查服务能力”新要求的理解与思考

《浙江省自然资源发展“十四五”规划纲要(征求意见稿)》,对基础地质工作提出了“提升服务能力”的新要求,具体是:全面推进区域地质调查、城市地质调查、水工环地质调查、地球物理和地球化学调查,建立基础地质核心数据库;开展精细化土地质量地质调查和天然富硒土地资源详查,建立土地质量地质调查数据库;推进生态功能区和海岸带等综合地质调查.     

贵州省市州域经济差异的时空演变

区域经济差异一直是国内外研究的热点,本文以贵州省9个市州为研究单位,选取10个经济发展指标,运用全局主成分分析,结合GIS技术,测度了贵州省9个市州域2006～2016年10年来经济差异的时空演变。结果表明:贵州省各市州区域经济内部差异明显,经济增长存在较强空间关联性,上升区与下降区均集中分布;各项指标数值相对比较大的地区,最终得分不一定高。     

经济地理学视角下创新网络与区域增长研究述评

创新是引领经济发展的第一动力，创新与区域增长之间的关系成为经济地理学者关注的重点领域。文章通过梳理近年来有关创新网络测度、创新网络与区域增长关系、创新网络作用于区域增长方式等方面的文献发现：网络资本可以弥补社会资本在解释企业创新结网经济价值方面的不足，区域增长呈现出网络化特征已成为学界共识，知识流与邻近性能较好地解释创新网络与区域增长的关系机理。然而，当前研究对社会资本如何促进区域增长，网络资本与区域增长关系模型如何构建，不同类型的邻近性与知识对区域增长的影响有何差异等问题尚不明确，建议重视网络资本对区域增长的作用并实证检验二者的关联，同时还应重视创新网络中企业家精神、创新个体心理行为特征等因素对区域增长的影响。     

海洋工程项目生态建设方案研究

为完善海洋工程项目的海洋环境影响评价和促进海洋生态文明建设,文章根据相关实践经验,从原则和依据、定位、生态空间和生态景观格局、污染物排放和控制、生态修复和补偿以及监测计划和保障等方面提出生态建设方案的内容,按照项目建设前、项目规划、项目设计和项目实施的全过程设置方案的程序,并以案例项目具体说明。在此基础上,总结目前海洋工程项目生态建设亟待解决的问题,即生态建设及其相关活动需重新定义、方案实施过程和效果的检验和评估无制度和规范保障以及方案编制缺乏整体性和区域性。     

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.

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。
