为打造“快递产业之乡”贡献力量     

胡群 《浙江国土资源》2020,(1):55-56

杭州市桐庐县地处钱塘江中游,富春江斜贯县境;范仲淹赞之为"潇洒桐庐",黄公望名作《富春山居图》所画景致70%取景于此,一直以来是全国著名的制笔之乡、针织名镇、箱包之城。随着近年来电商等行业的崛起,"快递之乡"成了桐庐县的新名片。2018年全国快递总量507.1亿件,其中超过50%的量(272.61亿件)。  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   

FEASIBLE STUDY ON THE INTEGRATION SYSTEM FOR THE SPACE MONITORING OF MAJOR EARTHQUAKES AND VOLCANOES IN TERRESTRIAL LAND   总被引：1，自引：1，他引：0

With the rapid development of space technology, earth observation technology and sky observatory technolo-gy, they have played a more and more important part in monitoring and predicting of earthquakes and volcanoes in the terres-trial land. In recent years, the related agencies have done the experiments and researches on monitoring and predicting ofearthquakes and volcanoes in the forewarning period by means of many approaches, such as satellite thermal infrared re-mote sensing (TIRS), Global Positioning System (GPS), differential interferometric synthesis aperture radar (D-INSAR),astronomical time-latitude residual anomaly, and Geographic Information Systems (GIS), etc. A quite large number of re-search foundation has been built in the fundamental theories and application methods. The experiments and researcheshave shown that these technology is efficient methods for high frequency crust movement. If the existed separate scientificforces and results are possibly assembled together to form a more complete integration monitoring system with the combina-tion of space, sky observation, ground, deep geology and macro anomaly, it will come into a new stage of monitoring andpredicting of earthquakes and volcanic eruptions.  相似文献

对青藏东北缘现今块体划分、运动及变形的初步研究   总被引：19，自引：9，他引：10  

张晓亮  江在森  陈兵  李辉 《大地测量与地球动力学》2002,22(1):63-67

利用2维非连续变形分析方法（DDA），以位移代替围压作为边界约束力，研究青藏东北缘现今块体划分及其运动变形。根据该地区地质构造及地震活动，以GPS点测量位移作为模拟结果约束点，得出了较合理的块体划分模型和随时间演化的主应变分布图，并把应变高值区与近几年来发生的5级以上地震作对比，得出了研究区内地震危险性可能较大的区域。另外，对模拟的甘青块体与阿拉善块体的边缘带断裂左旋运动做了大概计算。  相似文献

孤峰青青不纪年

早就听说仙都山有龙须草,黄帝炼丹得仙乘龙飞升,群臣攀龙须,须附而生草.这产仙草的仙山不由得令人神往.这次由楠溪江返程回杭,途中真的到了仙都山.仙都山,古称缙云山,那是因传说轩辕皇帝在鼎湖峰上置炉炼丹时,山的上空有绯红绯紫的五色云缭绕而得名.它属括苍山脉的北支,瓯江支流好溪从山间流过,呈九曲练溪,十里画廊.有奇峰一百六,异洞二十七,人们赞誉它集桂林之秀、黄山之奇、华山之险于一身.面对山门,这"九曲溪"、"十里廊"的长卷山水又如何着手游呢?幸亏有老朋友的领引,解决了这个难题,只花了半天时间,便游历了仙都山的精粹.  相似文献
