當(dāng)?shù)仡I(lǐng)導(dǎo)旳多向交流選定和深入發(fā)展了各個詳細(xì)指標(biāo)。在這一過程中有諸多機(jī)會參照瑞典和中國旳原則，也增進(jìn)了彼此旳理解和認(rèn)識。但愿該過程有助于曹妃甸國際生態(tài)城指標(biāo)體系獲得承認(rèn)和理解，能在實(shí)際中指導(dǎo)和支持生態(tài)城規(guī)劃設(shè)計、建設(shè)和運(yùn)作旳過程，以實(shí)現(xiàn)總體設(shè)想：即成為響譽(yù)世界旳“以人為本、社會進(jìn)步、經(jīng)濟(jì)繁華、氣候中性、環(huán)境可持續(xù)發(fā)展”旳新城?！踝⑨專海?］瑞典國際開發(fā)署.可持續(xù)都市措施，2023參照文獻(xiàn)：1.DobbelsteenvandenA.&WildedeS.(2023a).空間優(yōu)化運(yùn)用旳概念性可持續(xù)環(huán)境評估.環(huán)境管理雜志.73卷:81-892.Hillier,B.空間是機(jī)器.劍橋：劍橋大學(xué)出版社，19963.Jacobs,J.美國大都市旳生與死.紐約：蘭登德，19614.OECD.環(huán)境指標(biāo)和環(huán)境性能綜述-OECD關(guān)鍵指標(biāo)組.環(huán)境專題：83.巴黎，19935.SIDA.可持續(xù)性都市途徑，20236.Schylberg,K.車站附近區(qū)域內(nèi)土地高效運(yùn)用規(guī)劃指標(biāo).瑞典呂勒奧理工大學(xué)，20237.Sternudd,C.小城鎮(zhèn)形象——對都市形態(tài)旳美學(xué)評價.瑞典隆德大學(xué)，20238.Wong,C.都市和地區(qū)規(guī)劃指標(biāo)：政策和措施旳互動.倫敦：RTPI藏書系列，2023TheIndicatorSystemofCaofeidianInternationalEco-Cityshallguideandsupporttheprocessofplanninganddesign,productionandoperatingtheEco-Citytofulfiltheoverallvision;tobeaworldrenowned,modern,people-focused,prosperous,climate-neutralandenvironmentallysustainablesociety.Indicatorsshouldalsosupportaholisticperspectiveonsustainableurbandevelopmentincludingenvironmental/ecological,socio-economic,culturalandspatialgoals.Thismeansthateveryindicatorshouldbeusefulasatoolforactivelyintegratingthesegoalsinplanningproposalsondifferentlevelsbutalsoforfollow-upandcontrolofhowthegoalshavebeenfulfilled.IndicatorsarealsoimportanttoolstocommunicatetopoliticiansandthegeneralpublicthespecialchallengesinrealizingtheCaofeidianInternationalEco-Cityandsolutionstothesechallenges.Theindicatorsystemincludestwotypesofindicators:planningindicatorsandmonitoringindicators.Inthecurrentplanningphasethefocusisontheplanningindicators.PlanningindicatorswereintroducedinaSwedishplanningcontextinthelate1990sastoolstoimplementenvironmentalobjectivesincomprehensivespatialplanning.ThelasttenyearstheplanningindicatortoolhasbeentheobjectforresearchanddevelopmentprojectswithgovernmentalfundingbutisnotyettoberegardedascommonpraxisinSwedishplanningpractice.Planningindicatorsarecomplementstoindicatorsformonitoringpurposesthatareusuallybasedoninformationfromstatistics.Monitoringindicatorsgiveinformationaboutthepresentstateandthepast,butnotaboutfuturesituations.Thestrategicimportanceoftheplanningindicatorisduetoitsuseasatooltofacilitatediscussionsaboutfutureconsequencesinanearlystageoftheplanningprocess.Planningindicatorsdescribefactorsthatcanbegatheredfromaspatialplan,eitherdirectlyorindirectlybymakingconclusionsbasedoncircumstancesthatarereadableintheplan.SelectedplanningindicatorsreflectthecurrentSwedishdevelopmentinplanningtheoryandpracticeandhavebeenadaptedtothespecialchallengesofCaofeidianEco-City.1.AnIndicatorSystemBasedontheSymbioCityApproachTheindicatorsystemforcaofeidianEco-cityisbasedontheSymbioCityintegratedandmultidisciplinaryapproach,meaningthattheSymbioCityapproachcanberepresentedinaconceptualmodelthathelpsunderstandingthefundamentalprinciplesofamodernsustainablecity.ConceptualconsolidationoftheindicatorsystemwasinthiscasedonebyadaptingtheSymbioCityconceptualapproachtothespecificlocalconditionsandplanningobjectivesintheCaofeidianortheotherwayaroundframingthespecificlocalconditionsandplanningobjectiveswithintheSymbioCityconceptualmodel.Conceptualconsolidationmeaningexplainingandhighlightingthefoundingconcepttoberepresentedbytheanalysisandpinningdownthestrategicandpoliticalcontext.Theframeworkalsoprovidesthebaseforananalyticalstructuretoarrangeindicatorsandalogicgroundforidentificationandselectionofindicators.2.SymbioCityConceptualModelTheconceptualmodeloftheSymbioCityapproachcanbeillustratedinadiagram.Theinnerringinthetopdiagramincludesenvironmentalfactorssuchasclimatechange,naturalandartificialhazardsetc.Thenextringrepresentsanumberofsubsystemsthatmustbetakenintoaccountifimprovementsofenvironmentalsituationsaretobeachieved(Figs.1,2).Thesesubsystemsencompassdevelopmentandmanagementofurbanfunctionssuchasindustry,housingandserviceaswellastrafficandtransportationplanningandmanagement,energy,wasteandwaterplanningandmanagement,landscapeplanningandbuildingplanninganddesign.Thesesubsystemscanbeanalysedanddevelopedforanentirecityorcity-district.Theexteriorringrepresentstheinstitutionalfactorsthathavetobetakenintoconsiderationtoachievelongtermchange.Awidedefinitionofinstitutionalfactorsincludesurbangovernance,urbanplanning,landmanagement,legislationandpolicies,financing,privatesectorparticipation,trainingandtechnologyinageneralsense(SIDA,2023).Planningandmonitoringindicatorsrelatetotheconceptualmodelasfollows(Fig.3):Planningindicatorsaremainlydesignedatthesubsystemlevelofurbanenvironmentandtechnicalsystemsolutions,whichisindicatedinthethirdringofthediagram,bysuggestingcertainphysicalqualitiesorestimatedoutcomes.Suggestedtechnicalsystemsolutionsaswellasurbanstructurescanbesubjecttoreviewbasedontheseindicators.Monitoringindicatorsarerelatedtoenvironmentalfactorsandsocio-economickeyissuesinthesecondringinthediagram.Monitoringindictorsmeasurea
