广州市干道路网通达性及其对区域物流发展的影响

I广州市干道路网通达性及其对区域物流发展的影响评价专业名称：人文地理研究方向：区域经济分析与规划摘要路网通达性是反映一地陆上交通成本的指标，它指的是某地陆上对外联系的便捷程度。路网通达性对城市人流、物流运输的速度与效率有着重要的影响，尤其是干道路网通达性对某地的对外与对内的交流发挥着不可替代的作用。某地的干道路网的通达性水平对区域物流的发展至关重要，区域物流的发展已经渗透到城市生产生活的各个方面，深刻影响着城市的经济发展、推动城市发生天翻地覆的变化。物流的发展是时代的需要，物流发展也是新一轮城市化发展背景的产物。干道路网的通达性与物流发展有着正向的相关性，从定量上分析它们的相关机理，有助于把握干道路网交通和物流发展的规律，充分发挥干道路区外连接性和区内畅通的作用，提高物流效率。本文以广州市为研究对象，重点探讨广州市干道路交通节点的通达性，探寻广州市干道路网通达性与区域物流发展的内在关系，提出物流控下的平均物流-网络直径概念、物流发展的功能和意义、广州市各辖区物流发展的差异及其计算方法。本文研究的目的是定量分析市区内部各个区干道路网通达性的空间差异，探究这种差异对广州市各个区物流发展的影响机制，揭示物流发展的空间分异规律。在研究过程中，以广州市现代物流的发展需要为切入点，从广州市自身交通设施和与外界的交流便利程度两个方面，利用GIS技术，选择干道公路长度、干道公路的连接节点、干道公路周围的物流企业分布等统计指标，构建了干道路网通达水平对区域物流发展影响的指数函数方程模型。在定量评价广州市各II辖区的广州市路网通达性的基础上，结合影响物流企业布局的因素，利用SPSS和AHP软件包，分析广州市各辖区物流发展的状况，总结广州市物流发展的空间分异规律。通过研究，得出以下结论：（1）节点连通性和通达性指标与区域物流发展有密切的正相关性，干道路的区外连接性对区域物流发展的贡献率大于干道路区内通达性对区域物流发展的贡献率。（2）使用节点连通性和可达性指标可界定出各区域物流发展之间的空间相互作用范围，为整个区域的交通规划和物流规划提供有力的科学依据；广州市干道路交通呈辐射性模式，并且各个区之间有空间自相关性。（3）通过尝试在对广州市干道路网的通达性分析的基础之上，重点探讨了基于干道路网络特性的区域物流布局发展的度量方法分类体系与应用研究现状，总结了广州市各个区物流发展的特点和问题，并尝试性地提出了一些解决办法。关键词：干道路网；通达性；通达指向型；GIS；物流发展；广州市IIIGUANGZHOUTRUNKROADACCESSIBILITYANDITSIMPACTONTHEEVALUATIONOFDEVELOPMENTOFREGIONALLOGISTICSMajor：HumanGeographyResearchOrientation：AnalysisandPlanningofRegionalEconomyABSTRACTTheaccessibilityofroadnetworkisoneindexofaplacethatreflectsthecostoflandtransportation,anditreferstoaconvenientdegreeofexternallinkagesbyland.Theaccessibilityofroadnetworkhasanimportantimpactonthespeedandefficiencyoflogisticsandtransportation,especiallyonmainroadnetwork,whichplaysanirreplaceableroleintheexternalandinternalexchangesofacertainplace.Theaccessibilityleveloftrunkroadnetworkiscriticalforthedevelopmentofregionallogistics,andregionallogisticsdevelopmenthasbeengraduallyaffectingthecity'seconomicdevelopment,withearth-shakingchanges.What’smore,ithaspermeatedallaspectsofourlife,fromthecountrysidetotheurban.Logisticsdevelopmentistheneedsofthetimes,andlogisticsisalsoaproductofthebackgroundofurbanizationinanewroundofdevelopment.Thereisapositivecorrelationbetweentrunkroadnetworkaccessibilityandlogisticsdevelopment.Thisarticlefocusesonquantitativeanalysisoftheirrelevanceonthemechanismoftrunkroadnetworkaccessibilitycouplingwithlogisticdevelopment.Thestudywillhelptograspthelawintermsofdevelopmentoftransportationandlogistics,andsoastotakefulladvantageofthetrunkroadconnectivityandtheregionexternalconnectivityIVsmoothly,andimprovelogisticsefficiency.ThisstudybasedonGuangzhouCity,focusesontheaccessibilityofmainroadtrafficnode,andtriestoexploretheinternalrelationshipbetweenmainroadaccessibilityandregionallogisticsdevelopment.Thispaperproposedtheconceptofmeanlogisticsnetworkdiameterunderthelogisticscontrol,thefunctionandsignificanceoflogisticsdevelopment,thespatialdevelopmentdifferencesoflogisticsinGuangzhouperdistrictanditscalculationmethods.ThepurposeofthisstudyistoanalyzethevariousareaswithintheurbanpartofGuangzhoucity,toexplorethespatiallogisticsdifferencesinperdistrictofGuangzhou,aswellastosummarizeandrevealtheimpactoflogisticsdevelopmentmechanismandspatialdifferentiationoflogisticsdevelopment.Inthecourseofthestudy,itsobservationangleforanentrypointbeginsfromtwoaspects.OneistheneedandthedevelopmentofmodernlogisticsinGuangzhouandtheotherisitsowntransportationfacilitiesinGuangzhouandtheconvenienceofcommunicationwiththeoutsideworld.Inthisarticle,theauthorestablishedthemathematicalmodeltoevaluatetheaccessibilityleveloftrunkroadnetworkwhichlevelindexmodelaffectsonregionallogisticsdevelopment,usingGIStechnology,selectingthelengthoftrunkroad,trunkroadconnectingnodes,thelogisticsdistributionaroundthetrunkroadandotherstatisticalindicators.OnthebasisofthequantitativeevaluationoftrunkroadaccessibilityofthevariousdistrictsofGuangzhouCity,combinedwiththelayoutfactorsthataffectthelogisticsdistributionanddevelopment,byvirtueofAHP&SPSSsoftwarepackage,thepaperanalyzesthesituationoflogisticsdevelopmentinGuangzhouCity,thestatusofthearea,summarizesthespatialdifferentiationoflogisticsdevelopment.Throughtheresearch,thearticlehasdrawnthefollowingconclusions:(1)Nodeconnectivityandaccessibilityindexandregionallogisticsdevelopmentarecloselycorrelated,andtrunkroadconnectivityoutsidehasahighercontributionthantrunkroadaccessibilityontheregionallogisticsdevelopment.(2)TheuseofnodeconnectivityandaccessibilityindicatorscanbedefinedinregionallogisticsdevelopmentspatialinteractionsbetweenthescopeoftheentireVregion,whileitcanprovidetransportplanningandlogisticsplanningwithstrongscientificbasis;trunkroadsinGuangzhouCityshowradioactivemode,aswellaspresentingspatialautocorrelationbetweenthevariousdistricts.(3)OnthebasisoftheaccessibilityoftrunkroadnetworkinGuangzhou,thisstudyisanattemptofrevealingcharacteristicsofthelayoutandmetricclassificationsystemandapplicationofthedevelopmentofregionallogistics,summarizingthecharacteristicsandproblemsoflogisticsdevelopmentofGuangzhouonthewhole.Andthisarticletriestoputforwardsomesolutionsatlast.KEYWORDS:Trunkroadnetwork;accessibility;accessibilityorientation；GIS；logisticsdevelopment；GuangzhouVI目录摘要..............
