关系视角下台湾高山茶产业在大陆的嵌入过程及机理

基于新经济地理学的嵌入性理论和关系经济地理学理论,以永福镇台资高山茶产业为例,采用实地调研和深度访谈法,通过构建关系视角下的产业嵌入性分析框架,分析台湾高山茶产业在大陆的嵌入过程及机理,结果显示：1）永福镇台资高山茶企业的嵌入是一个渐进的过程,可分为社会嵌入、网络嵌入和地域嵌入3个方面。2）行动者—制度、行动者网络—组织间网络、地方—全球三重关系交织于永福镇台资高山茶企业的嵌入过程中,并深刻地影响着企业的嵌入过程与结果。此外,研究还发现：地方政府及中介机构在促进企业发展和网络重组等方面发挥着重要作用。对此,建议地方政府重视本土配套企业的培育与成长,同时应进一步鼓励企业间的交流,促进网络融合,不断提升台资高山茶企业的“嵌入”程度。     

地理学视角下的中国乡村贫困——源起、进展与展望

乡村贫困一直是困扰中国的现实难题之一,消除贫困是全面建成小康社会以及乡村振兴战略顺利实施的基础。一直以来,乡村贫困是经济学、社会学、政治学、心理学等不同学科高度重视的问题,相关研究成果日趋增多,但对乡村贫困空间表达较弱。地理学具有空间格局研究的优势,近年来其对乡村贫困的研究较为活跃,重点关注乡村贫困的源起、空间分布、地理特征等内容,与其他学科有极强的互补性。论文梳理了地理学乡村贫困的相关研究成果,对其内涵与标准、测度与空间格局、影响因素与发生机理、反贫困策略等研究进行归纳总结与综合评述,探讨已有研究存在的主要问题与未来研究方向的发展趋势,为深入开展本领域研究提供参考。     

Everything moves:The rapid changes in photogrammetry and remote sensing

Changes in technology are coming at an ever increasing pace.This holds for photogrammetry and remote sensing as well."Everything moves"-this is why I chose this topic to shed some light on some of the recent developments.Naturally,this undertaking can never be complete in the sense of covering all developments in Photogrammetry and Remote Sensing.Besides,the impact of Deep Learning in photogrammetry is not mentioned in this paper.This is a very personal account.People may not agree with some of my findings,but this is in the nature of science.In any case,this contribution is meant as a tribute to Gottfried's successful lifelong work.It is not a scientific paper in the traditional sense but rather a collection of thoughts that emerged over the 50 years of my professional career.It is also meant for an audience who has not necessarily a deep photogrammetric expert know-how.

井间电磁波CT技术在溶洞探测中的应用

肇庆大桥位于西江流域,是连接肇庆和珠江三角洲地区主要干线上的大桥。５个主桥墩位于溶洞和断层破碎带上,地质情况非常复杂。为了探明墩位下方的溶洞分布状况,每个墩布置了６－８个ＣＴ探测钻孔,每两个钻孔之间进行电磁波ＣＴ探测,结合地质墩位下方溶洞的分布状况。实际钻桩结果表明电磁波ＣＴ探测结果很有成铲。     

Influence of Continental Sources on Oceanic Air Composition at the Eastern Edge of the North Atlantic Ocean, TOR 1992–1995

The atmospheric concentrations of O3, NMHCs, PAN and NOx were measured at the TOR station in Porspoder (Brittany, France) from 1992 to 1995. The results from April 1992 to December 1994 are reported here. In order to study the behaviour of trace gases in the air masses coming from the Atlantic Ocean, the origin of these air masses was characterised by the analysis of the five-day back-trajectories reaching 950 mbar at Porspoder. Three kinds of oceanic air masses are considered, depending on their origin: North Atlantic northern and southern latitudes and North American continent. It appears that the oceanic high-latitude troposphere was strongly influenced by continental emissions, which in turn impacted the median latitude troposphere during polar outflow events. A greater accumulation of anthropogenic compounds in the Arctic sector was calculated and may be at the origin of the high oxidant levels measured in spring in this same sector. The influence of north American emissions on the European coast was also studied and seems to reach a maximum in spring. Long-range transport of long- lived species was observed throughout the year, but evidence for winter transport of more reactive species, such as ethene, is also shown. Meteorological parameters and local photochemistry appear to play an important role in the distribution of the pollutants over the North Atlantic Ocean throughout the year. Further investigations are needed to give more complete information about the origin, formation and destruction of the secondary pollutants.

High-precision measurements of the inter-annual evolution for Urumqi Glacier No.1 in eastern Tien Shan,China

High-precision measuring of glacier evolution remains a challenge as the available global and regional remote sensing techniques cannot satisfactorily capture the local-scale processes of most small- and medium-sized mountain glaciers. In this study, we use a high-precision local remote sensing technique, long-range terrestrial laser scanning (TLS), to measure the evolution of Urumqi Glacier No.1 at an annual scale. We found that the dense point clouds derived from the TLS survey can be used to reconstruct glacier surface terrain, with certain details, such as depressions, debris-covered areas, and supra-glacial drainages can be distinguished. The glacier experienced pronounced thickness thinning and continuous retreat over the last four mass-balance years (2015-2019). The mean surface slope of Urumqi Glacier No.1 gradually steepened, which may increase the removal of glacier mass. The glacier was deeply incised by two very prominent primary supra-glacial rivers, and those rivers presented a widening trend. Extensive networks of supra-glacial channels had a significant impact on accelerated glacier mass loss. High-precision measuring is of vital importance to understanding the annual evolution of this type of glacier.
