旅游流是社会网络关系的一种地域表现形式,国家(地区)之间旅游流网络中心度的差异可以被理解为国家(地区)之间一种不对称的社会活动相互作用关系。面对当前研究中存在的旅游流网络中心度刻画指标不清晰、时空规律不精确、影响因素不明朗等问题,本研究构建了5个网络中心度指标,并据此分析了全球各个国家(地区)入境旅游流总体特征与空间演化规律,识别了主要地理因素对旅游流规模的影响程度变化。结果发现:2004—2019年全球入境旅游流规模增长近一倍,亚洲地区之间旅游流规模快速提升;全球大多数国家(地区)旅游影响力、向心力和辐射力提升,中国各项旅游流网络中心度指标的提升速度均处于世界前列;多数中心度指标之间显著相关,其中约束力和辐射力与其他指标相关程度较低;地理邻近性对旅游流规模有显著且稳定的影响,人口规模不仅与亲和力等指标显著相关,并且对旅游流规模的影响程度在时间序列中显著提升。研究结果体现了中国入境旅游在全球旅游流网络结构中的持续向好态势和巨大发展潜力。  相似文献

荒漠灌木树干茎流及其生态水文效应研究进展   总被引:4,自引:0,他引:4  
树干茎流作为林冠层降雨截留再分配过程中的重要组成部分,影响着土壤-植物-大气连续体(SPAC)中不同尺度和圈层间的水分和养分循环的速度与方向,对荒漠地区灌木的生存和生长具有深远影响,对于土壤养分的溶解、利用,土壤水、地下水的循环与补给,土壤侵蚀过程等方面都有重要意义。本文系统总结了近年来荒漠地区灌木树干茎流研究的主要手段与方法,对影响树干茎流形成的主要因素、形成过程、变化趋势进行了具体论述,对主要的荒漠灌木树种树干茎流经验模型进行了归纳,并具体分析了树干茎流在生态水文学方面研究意义及主要进展。针对荒漠树干茎流尚有以下方面的问题需要进一步深入研究:(1)不同灌木树干茎流的形成过程、主要影响因素及其相互作用机制;(2)树干茎流集水系统的空间结构配置特征和降雨径流作用机制;(3)树干茎流补给在荒漠地区群落格局形成以及演替中的作用机理、荒漠植被特征与动态对截留、树干茎流、蒸散发以及入渗过程的反馈机制等。  相似文献

在气候变化的背景下,北极地区的战略地位不断提升,北极事务正深刻地影响着世界格局的演变。以北极8国为基础,进一步考虑北极理事会13个观察员国的影响,基于2001、2006、2011和2016年的GDP和贸易额数据,采用社会网络分析方法,结合贸易依存度和进出口位次分析,全面地揭示北极地区地缘经济关系的演变特征。研究表明:2001—2016年北极地区地缘经济关系先走向紧密,而后有所减弱;不同国家的地缘经济地位和影响力存在显著差异,双边存在不对等的贸易关系,具有明显的“核心-外围-边缘”的特征。美加双边贸易流尤为显著,占到北极国家间贸易流的70%以上;在美加双边关系上,加拿大对美国经济高度依赖,美国拥有充分的主导权;瑞典、丹麦、挪威和芬兰在地区内具有重要的地缘经济影响力,而冰岛和格陵兰地区则长期处于贸易网络的边缘地带,但二者都具有极其重要的地理位置,应引起重视;在北极地区地缘经济关系中,俄罗斯的经济影响力并未与其国际政治地位相匹配,拥有巨大的经贸潜力。德国、英国、法国、日本、意大利、荷兰和中国都是对北极地区地缘经济有显著影响的国家。以中国为代表的新兴经济体的地缘影响力在不断扩大,而一些传统经济大国的地缘经济优势呈不同程度的减弱趋势。总体来说,近年来北极地区的地缘经济关系基本格局并未发生本质变化。  相似文献

以四川西部地区为研究区,通过网络获取散客游记和团队线路数据,借助社会网络理论与方法,对比分析散客旅游流与团队旅游流在网络密度、程度中心度、结构洞及凝聚子群4个方面的异同。结果表明:团队旅游流网络的密度较散客旅游流网络密度大,反映出专业的旅游机构对旅游线路的设计和组织能增强旅游流的网络密度、提高景区间的连接性;散客旅游流网络和团队旅游流网络在核心节点的选择上既有差异也有共性,新都桥等5个景区在两个旅游流网络中都处于核心位置;两类旅游流所涉及的热门节点近一半发生重合,但在旅行社或旅游电商的宣传和组织下团队旅游流对景区的辐射带动作用更强。川西地区高知名度的九寨沟、黄龙等景区并未在旅游流网络中处于重要位置,反映出高原山体类旅游目的地旅游流受区域环境影响较大,需对其环境保护和地质灾害防治加以特别关注。  相似文献

旅游流对区域旅游开发规划具有重要指导作用,如何实现旅游流与区域经济、社会、自然环境的协调发展成为许多地区亟待思考的问题。该文借助社会网络理论和方法研究区域旅游流网络结构体系,从经济、社会、自然环境角度分析区域旅游流网络结构的环境影响因子;通过构建耦合协调度模型测量环境因子对区域旅游流网络结构的影响强度,并利用Moran指数对区域旅游流网络结构与环境的耦合协调度进行全局及局部自相关分析。最后以京津冀地区为例,探查该地区旅游流网络结构与环境的响应效果,为区域旅游流网络结构优化提供决策参考。  相似文献

信息通信技术(ICTs)正切实地影响着人类和社会状况:网络空间的出现和电信压缩空间使距离屏障失去意义.通过对西方学者过去十余年的主要探索成就进行综合.将评价电信在地区发展中作用的研究观点划分为三类,并分别予以评述.我们认为当前地理空间和网络空间交织在一起,处于一种融合过程,可把它叫做"地理网络空间".电信在地区发展和行为区位方面的作用及特殊优势仍有待于进一步研究.  相似文献

选取1997―2019年中国香港特区数据,使用定性比较分析(QCA)方法对出入境旅游流产生路径的前因条件以及结果条件进行分析,研究结果表明:① 在路径数量上,虽持续简化,但是仍然具有复杂性;② 在核心条件中,所有的单因素均不构成影响的核心条件,中国香港出入境旅游流路径受到多因素组合作用;③ 在前因条件中,“软?硬”关系影响存在差异,硬实力关系对高出入境旅游流起主导作用,软实力关系则对非高出入境旅游流作用较大;④ 在路径国家(地区)中,高和非高出入境旅游流存在显著地区差异;⑤ 在时间层面上,阶段1与阶段2、阶段3路径差异较大,表明时间节点的分割事件对中国香港出入境旅游的影响不同。  相似文献

在全球生态超载的背景下,贸易成为弥补国家或区域生态赤字的重要手段之一。本研究以"一带一路"国家为研究区,分析了中国与"一带一路"沿线国家(地区)的生态承载力与生态足迹变化特征,从生态承载力视角探究了贸易流动特点,采用虚拟土地的进出口量评估贸易对中国耕地与牧草地的资源缺口的弥补作用。主要结论有:1)2005–2014年绝大多数"一带一路"国家超载程度增大。中国生态承载力占比最大的是耕地,生态足迹以碳足迹为主。2)中国大陆的农牧产品贸易流具有进口量增大、出口量降低的趋势,加大了对特定区域的依赖。3)2005–2014年,中国大陆对"一带一路"沿线国家(地区)谷物和油料作物贸易一般为净进口,与"一带一路"沿线国家(地区)的谷物贸易所占比重逐渐提高,油料作物贸易比重迅速降低。4)进口贸易在一定程度上缓解了生态赤字,本研究选择的代表性农牧产品分别弥补了中国1.03倍的耕地赤字和0.65倍的草地赤字。本研究深化了对中国与"一带一路"国家(地区)土地资源利用与农牧产品国际贸易关系的认识,可为减少生态赤字、优化土地资源利用及推进中国与"一带一路"沿线国家(地区)合作共赢提供决策支持。  相似文献

虚拟旅游流一定程度上表征了游客需求的地理指向,是分析中国旅游业空间发展格局、推动国内大循环格局形成的重要突破点。论文利用2016—2020年百度指数搜索数据,基于虚拟旅游流流向视角,构建虚拟旅游吸引力与出游潜力指标,结合空间分析工具剖析其空间分布状况;通过虚拟旅游优势度与关联性分析各节点的作用与地位,系统考察虚拟旅游流网络结构的空间演变特征。研究发现:① 从虚拟旅游流空间结构来看,北京、上海及云南为中心地区,三地向外辐射,形成了以京津冀、长三角、云贵川渝地区为核心的虚拟空间结构。② 从虚拟旅游流的极化与扩散效应来看,长三角地区扩散效应显著,而京津冀及其以南地区和云贵川渝地区极化效应显著。其中,京津冀及其以南地区由双核结构转为单核结构;云贵川渝地区内外部联系不断增强,形成了多核心、多层级的强区域内循环结构。③ 基于虚拟旅游流网络结构演变特征分析发现,区域内部循环流动是促进区域内外部旅游均衡发展的有效途径。④ 经济发展水平、旅游资源禀赋、基础设施建设及时空邻近性等是影响虚拟旅游流网络结构演变的重要因素。  相似文献
