The Apuseni Mountains constitute one of the most interesting parts of the Carpathians in terms of landscape, biodiversity and culture. Yet dislocations are now severe and there are development threats which also require a significant response. On the one hand there are some severe pollution problems associated with mining areas developed in the communist period which require remedial action and the cases of Roşia Montana and Zlatna are discussed. On the other hand, there are forest and pasture zones – especially the Padiş Plateau – which are coming under heavy pressure from farmers seeking to enhance their incomes following the decline of mining and manufacturing which has left many households without salaries. At the same time, tourist pressure is growing. Actions are already being taken to limit pollution damage and develop sustainable landuse practices. There is a national park project linked with nature reserves comprising picturesque landscapes, a rare flora and fauna and distinct geological and palaeotological formations (including fossil ice). There are major tourist attractions and with proper management they could become part of a development programme of the countryside. However it is essential that all stakeholders adopt sustainable practices and this means that official programmes – including the future national park authority administration's work in environment protection and tourism management – are backed up by Environmental Non-Governmental Organisations (ENGOs). The paper reviews their diverse activities and concludes that they are making a very substantial contribution in ensuring that the potentials of isolated regions can be utilised in a manner consistent with nature conservation. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

四川省云阳县粮食低产坡耕地的综合冶理     

张朝元  唐治诚 《山地学报》1996,(4)

县内土地面积３６．４９万ｈｍ２，坡耕地面积３．４４万ｈｍ２．坡耕地粮食年产４５００－６５００ｋｇ／ｋｍ２．低产原因是土层瘠薄，缺土水肥．采取的综合治理措施有：建设农田基础设施，实行生物－工程措施，推行分带轮作三熟制等．由此粮食年产达１１０００—１２５００ｋｇ／ｈｍ２．  相似文献

浙江省常山县上震旦统西峰寺组碳酸盐的δ¹³C和δ¹⁸O测定          下载免费PDF全文

刘鸿允  陈孟莪  鲁刚毅 《地质科学》1992,(4):342

 作者对浙江省常山县三里亭北九家坞的上震旦统剖面的碳酸盐系统采集的54个样品,作了碳、氧稳定同位素的分析。其中δ¹³C除4个外几乎全为正值,平均值2.16%,这与前人提到过的文德期以δ¹³C负迁移为特征的结论不符。离散变为9.0。最大负峰值出现在剖面近中部的磷块岩层中,可能与海流状况的剧变有关。δ¹⁸O除最末两个为小的正值外,几乎全为负值。  相似文献   

玉田东吉庄饮用天然矿泉水成因分析及水质评价     

陆贺田  张志强 《华北地质矿产杂志》1995,10(4):495-499

东吉庄矿泉水是１９８９年由地质矿产部环境管理司会同卫生部、轻工业部等有关单位的国家饮用天然矿泉水技术评审组鉴定通过，符合ＧＢ８５３７－８７的国家标准要求，属含锶重碳酸镁·钙·钠型低矿化度中性饮用天然矿泉水，已于同年建立了奥玉饮料厂，生产瓶装矿泉水及奥玉饮料。为了保护矿泉水资源免遭环境污染，对该矿泉水水源地进行了水源地保护规划。  相似文献   

围场牌楼御圣饮用天然矿泉水     

王敏 《华北地质矿产杂志》1995,10(4):510-514

围场牌楼御圣矿泉水出露于侏罗系张家口组凝灰岩、安山岩中，属偏硅酸、锶复合型矿泉水，其成因是含偏硅酸和锶的岩石经地下水深循环作用，长期溶滤围岩，使偏硅酸、锶不断富集的结果，除含偏硅酸、锶外，还含有有益于人体健康的微量元素。该矿泉水水量充沛，动态稳定，水质良好。  相似文献

产于扬子板块北缘岚皋县境内的早古生代镁铁－超镁铁质煌斑杂岩中的绿色辉石捕虏晶及捕虏体，按其岩相学及化学成分可分成三种类型，它们是同一种岩浆在不同深度结晶分异的结果。绿色辉石岩系列是早古生代大陆边缘裂谷中超碱质基性岩浆活动的产物。同寄主煌斑杂岩的初始岩浆（煌斑岩浆）一样，是于裂谷作用不同阶段由交代富集的亏损地幔部分熔融所形成。  相似文献   

On Liaoximordellidae Fam. Nov. (Coleoptera, Insecta) from the Jurassic of Western Liaoning, China     

Wang Wenli Institute of Natural History  Beijing Natural History Museum Yang Zunyi 《《地质学报》英文版》1993,67(3)

A new insect family Liaoximordellidae (fam. nov.) has been named for a well-preserved specimen which was collected from the Upper Jurassic outcropping west of Daxinfangzi Village, Lingyuan County, Liaoning Province. The specimen can not be put into Mordellidae or Praemordellidae because it possesses some original and intermediate characters in morphology. It serves the study of mordellid evolution. Besides, the fossil group associated with the insect is important for the stratigraphic division of the Mesozoic in western Liaoning.  相似文献   

鲁甸乐马厂银矿床地质特征与成矿作用初探   总被引：1，自引：1，他引：0  

周云满 《矿床地质》1999,18(2):121-128

乐马厂银矿为地矿部“八五”重点普查项目,普查找矿取得了突破性进展,矿床达大型规模。该矿床类型独特,为国内、外少见的独立银矿床,因此对矿床地质特征和矿床赋存规律进行了较深入研究,取得了新的认识。文章在乐马厂银矿床地质背景基础上,着重研究了该矿床的地质特征及成矿地质作用,并论述了其为产于叠瓦状逆冲－推覆断裂破碎蚀变带中的独立银矿床,其矿化作用过程经历了古构造－沉积（矿源层形成）和构造－热液（充填交代富集）两个阶段,构造活动控制了银矿化作用和银矿体的最终定位。这对在滇东北地区寻找此类银、铅锌矿床具有指导意义。  相似文献
