基于精明增长的城市空间扩展分析——以兰州市为例-analysis of urban spatial expansion based on smart growth a case study of lanzhou city.docx

（2）基于精明增长视角的国外城市空间扩展调控实践解析对于已经经历城市化快速阶段的城市空间扩展的调控实践考察，不仅有助于了解城市化快速阶段的空间扩展特征，而且有助于认识其调控的思想策略变化。因此，不论是美国精明增长的实践剖析，还是基于精明增长视角的英国、法国、日本等国家的城市调控实践解析，对科学理解基于精明增长的城市空间扩展策略提供了实践基础，为以GDP为导向的、背离于我国基本国情、资源环境基础与城市化进程要求的我国城市空间扩展提供了借鉴契机，在比较分析的基础上，提出了借鉴的前提与借鉴的重点。（3）基于精明增长视角的兰州市建设用地空间扩展分析与评价兰州市位于生态环境较为脆弱的西部欠发达地区，与东部地区相比较，其限制性因素多而发展差距大。因此，选择精明增长的城市空间扩展更有其紧迫性。论文基于市域与市区两个层面，通过GIS、SPSS等方法定量分析了其扩展过程特点与扩展机制，揭示了河谷型城市的空间扩展基本规律。并基于精明增长视角分析其扩展效应，形成河谷型城市空间扩展的基本趋势判断，在此基础上，提出了基于精明增长的河谷型城市空间扩展的策略性措施与政策性建议。关键词：城市空间扩展，精明增长，兰州市ABSTRACTNowadays，withthedevelopmentofurbanizationandeconomicofChina,Allcitiesinourcountryaregoingthroughahistoricalprocessofspatialexpandingandgreatchangingofstructureform,sothatallthecitieswanttobea“globecity”or“supercity”.However,aseriesofcrisesarecoming,suchasdecreasingofcultivableplough,overloadingoftheenvironment,lowefficientofdevelopmentandlaggingbehindofbasicfacilities.Soitisimportanttochooseareliablewaytocontrolthespatialexpansion，whichnotonlyenhancethegoalofusingthelandefficiently,butalsoimprovethedevelopmentofurbaneconomicandenvironment.Therefore,ithasarousedawidespreadattentionfordifferentlevelsofgovernmentsandinstitutes.Urbanspatialexpansionisoneofthemostimportantfeaturesoftheurbanization,itsoutsideappearanceisthescaleexpansioninmacroscopicviewanddifferentkindsofaggriculturelandchangeintotheurbanlandinmicroscopicview.Theessenceofurbanspatialexpansionisthecourseofnon-constructivelandtransformingintotheurbanlandbythedifferentimpetusesfrominsideandoutside,atsametimeitalsoincludesthechangeofspatialelements,thespatialformandstructurefromtheplaneandvertical.Urbanspatialexpansionalwaysfacesmuchproblemssuchasgrowthdirection,non-economic,ecologicalenvironmentproblem,andpolicyproblemthathowtochoosethebestmodelandwayforspatialexpansion.Inwesterncountries,confrontingwiththeruralsprawl,acomprehensivenewtheorynamed“smartgrowth”isspringingup,whosebasicideaisthecompactlanduse,resourcesavingeandmuchtoolsusenesstogether.Therefore,“Smartgrowth”canbeviewedasawayofanalyzingthereasonab
