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.     

广西田阳-那坡县堆积铝土矿分布规律初探

文章试图通过古地理环境、地质构造条件、沉积铝土矿及矿区地貌等因素去初步探讨田阳县-那坡县一带堆积铝土矿优质矿石及含矿率分布的规律性.认为沉积铝土矿及地貌因素是控制该地区堆积铝土矿优质矿石及含矿率分布的主要因素.     

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.     

天人合一:古代中国的生态观

鲁宣公是春秋时期(距今2600多年前)一位颇有作为的诸候,他在鲁国最早实行了"初税亩",按今天的说法就是废公田划私有,百姓按亩纳税.这在当时是一划时代的进步,诞生了最初的封建社会.     

景观生态分类与制图浅议

本文在查阅分析大量文献和前人研究的基础上 ,对目前景观生态分类和景观制图作了详细的对比分析 ,认为景观分类需要结合实际区域现状 ,采用逐级分类的方法 ;同时利用 ETM遥感影像为数据源 ,以天山北麓为示范区.研制其土地利用土地覆盖变化的景观类型图。     

SPATIAL—TEMPORAL VARIATION OF HEAVY METAL ELEMENTS CONTENT IN COVERING SPIL OF RECLAMATION AREA IN FUSHUN COAL MINE

Grid method is employed for sampling covering soil at the test field,which is reclamation area filled by coal mining wastes for cropland in the Fushun coal mine,Liaoning Province,the Northeast China.The soil samples are taken at different locations,including three kinds of covering soil,three different depths of soil layers and four different covering ages of covering soil.The spatial-temporal variation of heavy metal element content in reclamation soil is stud-ied.The results indicate that the content of heavy metal elements is decreasing year after year,the determinant reason why the content of heavy metal elements at 60cm depth layer is higher than that at 30cm depth layer and surface is fertiliz-er and manure application;the metal elements mainly come from external environment;there is no metal pollution coming from mother material (coal mining wastes)in plough layer of covering soil.     

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     

中国1∶100万景观生态制图设计

中国1∶100万景观生态图系借鉴国内外传统景观制图方法和制图规范,在遥感、地理信息系统先进技术的支持下,设计研制其制图方法、制图内容、样图和技术流程,同时提出初步的景观分类系统,为今后编制中国1∶100万景观生态图奠定基础。
