中原经济区县际经济联系网络结构及其演化特征

以中原经济区县级行政单元为网络节点,利用重力模型分别测算1996 年、2010 年226 个节点间的经济联系强度。首先设定同一阈值筛选有效连接,分析网络连通能力变化;再设定不同阈值,分析网络结构及其演化特征。研究发现：① 中原经济区经济网络连通能力有大幅度提高,经济发展和交通改善是网络稠密化和便捷化的主要原因。② 节点连通能力差异很大,少数节点掌握着绝对的网络权力,郑州市等5 个核心节点的地位尤其突出,其连线呈横向“T”字形状,建设“十”字形发展轴需要提升东部节点的连通能力。③ 网络呈明显的核心-外围结构并有极化趋势,核心区影响力和辐射力进一步增强,中原经济区只有提高边缘“洼地”节点连通能力才能加强与毗邻区的融合发展。④ 网络节点集聚现象明显,围绕次级核心节点形成了多个轴-辐结构子网络,“十”字形发展轴和“米”字形发展带的构建与发展,将有利于形成多重轴-辐结构嵌套的经济联系网络。⑤ 郑州市等高度值节点因较强的连通能力成为网络中的中介节点,一些度值不高的节点因处于“结构洞”位置上也具有较强的中介作用,在提高中介节点连通能力的同时,需要改善低度值中介节点所在小区域的经济和交通状况。     

关于中原经济区建设的区域布局构想

建设中原经济区,形成中原经济区区域内分工协作、优势互补、良性互动、共同发展的局面,必须有科学的区域布局.为此,提出了中原经济区地域发展布局的战略构想:升级以郑汴洛地区为主体的带动中原经济区发展的最重要的增长轴;强化以郑州市为中心和以洛阳市为副中心的核心增长极;构建中原城市群的核心圈、紧密圈、辐射圈;协调推进产业集聚区建设、粮食核心区建设、生态保护区建设和文化开发区建设;培育沿京广交通线经济带、沿陇海交通线经济带、沿焦枝交通线经济带、沿京九交通线经济带、沿西宁交通线经济带.     

兰西城市群空间结构演变及优化研究

对兰西城市群规模结构和网络结构特征及变动规律进行了研究。结果显示:规模结构的Kernel密度在整体上存在着“东高西低”的特点,东西带状分布明显,区域内部差异较大;城市群“核心-边缘”的结构模式明显,“点-轴-面”的演化进程缓慢,由于辐射能力有限,“双圈”间的经济带联系存在一定程度的“断裂”。网络结构上,2001—2017年城市间的联系有一定的提升,西宁-海东都市圈节点城市的经济联系弱于兰州-白银都市圈的节点城市;城市群经济发展仍表现为向兰州和西宁集聚变动;城市间的联系多要通过兰州和西宁发挥作用,网络结构单一,且城市间的联系有依赖于行政区划分演变的趋势。     

北部湾城市群旅游经济联系空间结构演变及优化研究

从旅游经济联系视角提出城市群生命周期理论,运用修正引力模型和社会网络分析法,对2011—2019年北部湾新兴城市群旅游经济联系空间结构演变进行研究。结果表明：1）北部湾城市群旅游经济联系逐步加深,2019年联系总量是2011年的37.42倍,旅游经济联系结构由松散发展为多核心网络结构。2）北部湾城市群旅游经济联系网络密度翻了6.01倍,网络结构从松散联系型转变为较紧密联系型,旅游经济核心区范围不断扩大,边缘区内部的旅游经济联系仍较弱。3）城市群中心性由严重两极化及城市间发展地位悬殊,演化为较均衡发展态势;从以南宁为单一中心,演化为“3中心-7节点-5边缘”的网络型空间结构。南宁、湛江和海口是北部湾重要的旅游中心和增长极。4）北部湾城市群历经雏形期进入成长期,目前尚未成为成熟期城市群,研究提出“政府推动+交通联动+产业互动”的北部湾城市群优化发展机制,以期促进城市群高质量协同发展。     

中原城市群人口流动空间格局与网络结构韧性分析

针对都市圈建设发展较快与超设防事件频发现象,评估和分析城市群网络结构韧性水平对区域一体化与健康可持续发展具有重大意义。该文以中原城市群为研究区域,基于2017年“腾讯迁徙”数据构建城市网络人口流动矩阵,分析城市群内部人口流动规模与特征,并从层级性、中断场景下传输性以及脆弱性对城市网络韧性进行评价。结果表明：(1)不同时段中原城市群人口流动具有规律性,节假日期间郑州与多数城市的人口流动状况具有动态平衡性;(2)不同时段高层级人口流动网络主要呈现为以郑州为核心的发散式结构;(3)中原城市群网络层级性显著,整体表现为单核心网络,介数策略对网络的破坏性最大,拥有高介数的节点在网络中承担核心作用;(4)郑州、洛阳、周口等核心城市节点对整体网络效率影响更大,中原城市群韧性水平整体良好,具有“十”字形空间特征,但部分规划核心城市的协同发展仍有待提高,未来需完善不同等级、规模、职能的城市协同发展机制,实现城市网络韧性水平整体提升。     

基于多源数据的城市旅游流空间网络结构特征——以洛阳市为例

对网络大数据和社会调研数据的融合、挖掘,构建洛阳市区各景点间游客流动的关系矩阵,基于社会网络和空间统计分析方法,探究洛阳市区旅游流空间网络结构特征。结论如下：①洛阳市区旅游流网络呈现出东南龙门石窟和东北白马寺旅游区极为密集,中心老城区网络联系较为紧密,北部邙山旅游区相对稀疏,西部旅游区几乎孤立的空间分布格局,表现出明显的四大旅游集群的态势。②洛阳市区旅游流网络是典型的核心-边缘网络,且核心景区对边缘景区的“涓滴效用”有限。③洛阳市区旅游节点分为4个系统,分别为一级旅游核心、次级旅游核心、一般旅游节点和边缘旅游节点。④ 一级核心景点涉及面较广,对整体流动具有较强的支配作用,而边缘节点主要受到一级和次核心节点的约束。     

城市群创新联系网络结构与创新效率研究

引入修正引力模型、社会网络分析方法、DEA模型以及Tobit模型,探讨2001—2015年京津冀、长三角、珠三角三大城市群的创新联系网络结构对创新效率的影响。研究表明：① 创新联系格局方面,京津冀城市群呈现以“京津”为核心的放射状发展特征,长三角城市群呈现以“Z”字形为主轴的类钻石型空间格局,珠三角城市群形成了以珠江口两侧城市为核心、其他城市为重要节点的空间格局;② 在创新联系网络结构特征方面,京津冀城市群呈极核式发展,群内创新联系高度依赖于核心城市,长三角和珠三角城市群由单中心驱动转变为多中心驱动,呈均衡发展特征,京津冀和珠三角城市群创新联系网络具有“小世界”网络特征;③ Tobit模型回归结果显示,三大城市群中,城市节点在城市群创新联系网络中的中心位置、中介地位、对结构洞的运用能力和集聚程度对其创新效率的影响存在差异。     

中原城市群城市引力范围界定及演变格局

通过构建反映城市综合实力的指标体系,运用熵值法对中原城市群30个城市2005,2010,2015年的综合实力分别进行测算与评定,运用基于扩展断裂点模型的加权Voronoi图方法对中原城市群各城市引力范围进行划分并展示了城市间引力界线的变化趋势,揭示了中原城市群30个城市3个年份的城市引力范围时空演变特征和变化规律。结果表明:3个年份,综合实力较高的地区基本分布在中原城市群中部和北部,东南部城市综合实力较弱,排名靠后,呈现出中北高、东南低两极化的发展规律;目前中原城市群城市引力范围格局中,郑州市的引力范围最大,其次是洛阳市、邯郸市,已经形成了以郑州为城市群核心的空间格局;3个年份,中原城市群的城市影响范围演变格局总体较为稳定,局部地区空间吸引范围变化较为明显,中、北部城市发展态势良好,影响范围有向北扩大的趋势;城市引力范围与其综合实力不完全呈正相关关系。     

中原经济区城市相互关联的时空格局研究

运用SPSS和Arc GIS分析技术,从城市职能互补和水平联系两种关联机制入手,对中原经济区2004,2009,2014年城市之间相互关联特征展开研究。结果表明:(1)中原经济区各个城市之间职能互补性不强,且城市潜在的职能互补性不断减弱,多数城市趋于综合化发展,九大职能部门中仅采掘业表现出专业化发展的趋势,其他职能部门均趋于综合化发展;(2)水平联系格局以郑州和邯郸为中心,中原城市群城市之间的联系强度大于其他两类区域(中原城市群以外主体区和中原经济区非主体区),呈现出"中心-外围"的空间格局;(3)从经济因素、区位因素、政策因素3个方面对中原经济区城市相互关联格局的形成进行了分析。     

长江经济带经济网络结构演变及其驱动机制研究

在构建城市间经济联系网络基础上,从网络密度、中心性、核心-边缘结构、QAP分析等角度对1988~2012年长江经济带经济网络结构演变及其驱动机制进行深入分析。结果表明：长江经济带经济联系网络结构日趋成熟,三大经济地带内城市内聚性显著增强但地带间差异逐渐缩小,经济网络向均衡化发展;城市度中心性整体持续下降,经济网络出现多核心趋势,城市介中心性高值区的梯度推移特征明显;“核心-边缘”结构分析显示核心度高值区呈片状格局,高核心度城市由“质大量少”向“质小量多”转变,经济网络的“核心-边缘”结构呈组团式发展,组团内形成各自核心城市;QAP分析显示经济全球化、要素集聚与扩散、产业升级、交通技术创新与城市群建设等机制共同驱动着长江经济带经济联系网络的演变及优化重组。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
