珍惜拥有--SARS后的反思     

陈廷一 《国土资源》2003,(10):12-21

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。  相似文献   

A CASE STUDY ON CONCENTRATION AND DECENTRALIZATION：BEHAVIOR AND DYNAMIC MECHANISM OF SPATIAL EVOLUTION IN METROPOLITAN AREA，NANJING，CHINA   总被引：1，自引：1，他引：0

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.  相似文献   

红阳煤田石炭-二叠纪含煤地层的沉积特征     

黄振裕  毛飞 《国土资源》1992,(4)

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。  相似文献

对推进城镇化健康发展问题的思考     

师银燕 《广东海洋大学学报》2005,25(5):38

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”。  相似文献

莱州湾南岸潍河下游地区咸水入侵灾害成因及特征   总被引：8，自引：1，他引：7  

刘恩峰  张祖陆  沈吉  宋俊峰 《地球科学与环境学报》2004,26(3):78-82,87

通过对莱州湾南岸咸水入侵较严重地潍河下游地区晚更新世以来沉积特征及现代自然环境条件变化的分析，探讨了沉积相对咸水入侵产生及空间范围特征的环境机理。晚更新世以来的三次海平面升降变化造成了潍河下游地区海陆沉积环境交替，形成了巨厚的海陆交互相沉积层。海进时期，大面积的滨海平原被淹没，在近海平原洼地滞留的海水经过蒸发、浓缩变为卤水，成为咸水入侵的物源；海退后陆源碎屑在滨海地区沉积形成了巨厚的古河道砂层。20世纪70年代末期以来，随着对地下淡水的过度开采，淡咸水水头压力差减小．卤水通过古河道砂层快速南侵。通过对潍河下游地区100余个地质钻孔水化学连续监测资料分析，阐明了咸水入侵的特征，有针对性地提出了咸水入侵的防治措施。  相似文献   

Revisiting Sustainable Development of Dry Valleys in Hengduan Mountains Region   总被引：5，自引：1，他引：4  

TANGYa XIEJiasui SUNHui 《山地科学学报》2004,1(1):38-45

Dry valleys are a striking geographic landscape in Hengduan Mountains Region and are characterized by low rainfall, desert type of vegetation and fragile environment. Past efforts and resources have been concentrated mainly on rehabilitation of degraded ecosystem and fragile environment, particularly reforestation, while socio-economic development has been largely overlooked. Despite successes in pocket areas, the overall trend of unsustainability and environmental deterioration are continuing. It is important to understand that uplift of the Tibetan Plateau is the root cause of development of dry valleys, and development and formation of dry valleys is a natural process. Human intervention has played a secondary role in development of dry valleys and degradation of dry valleys though human intervention in many cases has speeded up environmental degradation of the dry valleys. It is important to understand that dry valleys are climatic enclaves and an integrated approach that combines rehabilitation of degraded ecosystems and socio-economic development should be adopted if the overall goal of sustainable development of dry valleys is to be achieved. Promotion of niche-based cash crops, rural energy including hydropower, solar energy, biogas and fuelwood plantation is recommended as the priority activities.  相似文献
