【摘要】：城市規(guī)模反映了城市地域空間內(nèi)物質(zhì)與要素的聚集和擴(kuò)散程度,是一個(gè)具有社會(huì)經(jīng)濟(jì)意義和環(huán)境意義的數(shù)量概念,從社會(huì)發(fā)展的角度上講,城市規(guī)模是城市內(nèi)部“流”的集合,這種“流”包括人的流動(dòng)、物質(zhì)的流動(dòng)、經(jīng)濟(jì)的流動(dòng),是城市功能中需求與供給磨合所形成的動(dòng)態(tài)發(fā)展的規(guī)模特征；從城市規(guī)劃的角度上講,城市規(guī)模是城市內(nèi)部的“塊”,由于城市要素聚集的差異性、層次性造成各種城市要素在不同區(qū)位上形成的分布形態(tài)�！傲鳌笔浅鞘幸�(guī)模的動(dòng)態(tài)表現(xiàn),是在形成規(guī)模的過(guò)程中,人、經(jīng)濟(jì)、空間進(jìn)行的一系列交流與演化；“塊”是城市規(guī)模的靜態(tài)表現(xiàn),是在演化過(guò)程中不斷累積下來(lái)的聚集形態(tài),城市規(guī)模分布形態(tài)在動(dòng)態(tài)與靜態(tài)之間相互協(xié)調(diào)。城市作為一個(gè)“經(jīng)濟(jì)景觀”,是空間經(jīng)濟(jì)體系格局的最高表現(xiàn),是社會(huì)經(jīng)濟(jì)活動(dòng)空間聚集的結(jié)果,已有研究證明城市經(jīng)濟(jì)規(guī)模與城市人口、空間規(guī)模存在顯著的正相關(guān)性,經(jīng)濟(jì)規(guī)模就像一只看不見的手,始終影響著城市的總體規(guī)模發(fā)展,是城市規(guī)模發(fā)展的主要因素。隨著城市規(guī)模的不斷擴(kuò)大,一味地加大或者控制交通基礎(chǔ)設(shè)施建設(shè),都將使得交通基礎(chǔ)設(shè)施成為城市系統(tǒng)的短板,單純從供給的層面已經(jīng)難以解釋交通基礎(chǔ)設(shè)施建設(shè)最根本的問(wèn)題,部分文獻(xiàn)獨(dú)立分析城市規(guī)模分布或者交通網(wǎng)絡(luò)形態(tài),缺乏對(duì)兩者在城市發(fā)展過(guò)程中的互動(dòng)演化機(jī)理和協(xié)調(diào)耦合過(guò)程的分析,單從系統(tǒng)“迭代”的角度構(gòu)建演化模型,對(duì)兩者的“互動(dòng)”過(guò)程考慮不足。故此,本文基于城市的經(jīng)濟(jì)規(guī)模分布和交通基礎(chǔ)設(shè)施構(gòu)建宏觀交通綜合系統(tǒng),從系統(tǒng)內(nèi)交通基礎(chǔ)設(shè)施網(wǎng)絡(luò)和經(jīng)濟(jì)規(guī)模分布的互動(dòng)協(xié)調(diào)、耦合優(yōu)化的本質(zhì)出發(fā),結(jié)合定性及定量研究,揭示系統(tǒng)發(fā)展過(guò)程中的內(nèi)部固有機(jī)理和內(nèi)在規(guī)律,從機(jī)理上分析、識(shí)別、解決城市不同發(fā)展階段的交通與經(jīng)濟(jì)互動(dòng)協(xié)調(diào)問(wèn)題,對(duì)城市交通基礎(chǔ)設(shè)施投資進(jìn)行有效決策提供有意義的理論參考。城市交通基礎(chǔ)設(shè)施與經(jīng)濟(jì)規(guī)模分布的互饋影響、調(diào)節(jié)過(guò)程實(shí)質(zhì)就是系統(tǒng)優(yōu)化調(diào)節(jié)的過(guò)程。但由于系統(tǒng)的隱形特征,不易直接發(fā)現(xiàn)兩者的互動(dòng)規(guī)律,論文基于現(xiàn)象特征分析兩者之間的內(nèi)在互動(dòng)規(guī)律,通過(guò)理論模型推導(dǎo)揭示了交通基礎(chǔ)設(shè)施與經(jīng)濟(jì)規(guī)模分布演化之間的演化機(jī)制,并提出了基于主導(dǎo)演化機(jī)制交替而形成的三種系統(tǒng)演化模式。為了進(jìn)一步揭示城市交通基礎(chǔ)設(shè)施和經(jīng)濟(jì)規(guī)模分布的互動(dòng)演化過(guò)程,結(jié)合城市經(jīng)濟(jì)自組織發(fā)展機(jī)制和交通建設(shè)他組織干預(yù)機(jī)制,以系統(tǒng)發(fā)展的穩(wěn)定性為前提,以土地地租水平代表經(jīng)濟(jì)指標(biāo),構(gòu)建了基于三種系統(tǒng)演化模式的機(jī)理模型,利用微分方程的穩(wěn)定性理論對(duì)模型進(jìn)行仿真,還原不同系統(tǒng)模式下的演化進(jìn)程,反映兩者互饋發(fā)展的非線性特征,揭示了不同發(fā)展機(jī)制下系統(tǒng)演化方向的客觀差異和演化波動(dòng)穩(wěn)定特性的客觀存在,同時(shí)驗(yàn)證了他組織干預(yù)手段對(duì)系統(tǒng)演化的重要影響,初步樹立了城市交通基礎(chǔ)設(shè)施與經(jīng)濟(jì)規(guī)模分布綜合系統(tǒng)的演化觀。然而,建立系統(tǒng)演化觀的目的不僅是了解系統(tǒng)的演化進(jìn)程,更要對(duì)城市交通基礎(chǔ)設(shè)施和經(jīng)濟(jì)規(guī)模分布的協(xié)調(diào)關(guān)系進(jìn)行辨識(shí),由于系統(tǒng)動(dòng)力交替的隱性關(guān)系,難以直觀得出交通基礎(chǔ)設(shè)施和經(jīng)濟(jì)規(guī)模分布的發(fā)展階段,基于分形理論,利用經(jīng)濟(jì)規(guī)模分布的Zipf分布形態(tài)和交通網(wǎng)絡(luò)的分枝分維,構(gòu)建子系統(tǒng)之間的協(xié)調(diào)辨識(shí)模型,明確系統(tǒng)所處的機(jī)制演化階段,并且對(duì)系統(tǒng)未來(lái)演化方向進(jìn)行有效預(yù)測(cè),一方面明確城市需求與供給的關(guān)系,判別城市是否健康發(fā)展,另一方面給政府應(yīng)采取的干預(yù)手段提供決策依據(jù)。最后,基于對(duì)系統(tǒng)協(xié)調(diào)性的辨識(shí),理清交通基礎(chǔ)設(shè)施和經(jīng)濟(jì)規(guī)模分布形態(tài)之間的互動(dòng)階段,進(jìn)而對(duì)交通基礎(chǔ)設(shè)施進(jìn)行有效的投資決策,論文據(jù)此思路,基于宏觀經(jīng)濟(jì)學(xué)模型和城市形態(tài)的分形原理,提出干線通道方案和地區(qū)交通投資結(jié)構(gòu)兩方面的優(yōu)化決策方法。前者著眼于干線交通通道的重要度,結(jié)合干線方案的經(jīng)濟(jì)效益和對(duì)經(jīng)濟(jì)形態(tài)演化的貢獻(xiàn)能力,構(gòu)建組合決策模型,提出干線交通通道的優(yōu)選方案；后者針對(duì)組團(tuán)內(nèi)、組團(tuán)間兩種交通基礎(chǔ)設(shè)施所產(chǎn)生的不同經(jīng)濟(jì)效益,以經(jīng)濟(jì)規(guī)模分布形態(tài)的協(xié)調(diào)進(jìn)化為約束,構(gòu)建地區(qū)經(jīng)濟(jì)效益最大化的目標(biāo)函數(shù)。兩個(gè)模型構(gòu)建使得交通基礎(chǔ)設(shè)施建設(shè)投資滿足經(jīng)濟(jì)效益最大化的同時(shí),引導(dǎo)地區(qū)經(jīng)濟(jì)規(guī)模的分布形態(tài)向更為協(xié)調(diào)的方向演化,通過(guò)成都市的實(shí)際統(tǒng)計(jì)數(shù)據(jù),驗(yàn)證了模型及算法的有效性和可操作性。
[Abstract]:The scale of the city reflects the accumulation and spread of the material and elements in the urban area . It is a quantitative concept with social and economic significance and environmental meaning . From the perspective of social development , the scale of the city is the collection of " streams " in the city . This " flow " includes the movement of people , the flow of material and the flow of the economy , and is the scale characteristic of the dynamic development of the demand and supply of the urban function ;
From the point of view of city planning , the city scale is the " block " inside the city . Due to the difference of urban element aggregation , the hierarchy causes various urban elements to form distribution patterns on different locations . " Flow " is the dynamic performance of the city scale , which is a series of communication and evolution of human , economy and space during the process of forming scale ;
The " block " is a static representation of the scale of the city . It is an aggregate form that continues to accumulate in the evolution process . The urban scale distribution pattern is coordinated with each other in the dynamic and static state . The city is a " economic landscape " In order to further reveal the interaction between urban traffic infrastructure and economic scale , this paper points out that the interaction between urban traffic infrastructure and economic scale is the most fundamental factor in the development of urban transportation infrastructure . On the one hand , based on the identification of system coordination , the interaction between the traffic infrastructure and the distribution pattern of economy scale is established , and the decision - making method is provided . Finally , based on the identification of system coordination , the economic benefit of the trunk scheme and the contribution ability to the evolution of the economy form , the combination decision model is constructed , and the preferred scheme of the trunk traffic channel is proposed .
The latter aims at the different economic benefits generated by the two kinds of transportation infrastructure in the group , the coordinated evolution of the economic scale distribution form as the constraint , and the objective function of maximizing the economic benefit of the region . The two models are constructed so that the investment in the construction of the transportation infrastructure can meet the maximum economic benefit , and the distribution pattern of the regional economic scale is evolved to the more coordinated direction , and the validity and operability of the model and the algorithm are verified through the actual statistical data of Chengdu .
