【摘要】：國(guó)內(nèi)超大城市已進(jìn)入都市區(qū)發(fā)展階段,但相關(guān)理論卻相對(duì)滯后,研究我國(guó)都市區(qū)的空間尺度問(wèn)題有利于科學(xué)地制定城市政策,預(yù)留規(guī)劃設(shè)施,促進(jìn)都市區(qū)健康發(fā)展。本文從出行時(shí)耗角度入手,分析歸納國(guó)外發(fā)達(dá)國(guó)家都市區(qū)發(fā)展歷程與當(dāng)前特征,結(jié)合京滬等都市區(qū)發(fā)展現(xiàn)狀及通勤時(shí)耗特征,研判我國(guó)大都市區(qū)空間尺度問(wèn)題。研究結(jié)論證實(shí)我國(guó)大城市都市區(qū)空間拓展應(yīng)以軌道交通為主要支撐方式,小汽車(chē)模式雖然出行效率較高,但邊際成本較高,不適合我國(guó)城市高強(qiáng)度開(kāi)發(fā)特點(diǎn)。在軌道網(wǎng)絡(luò)化條件下,從出行時(shí)耗的角度,提出都市區(qū)內(nèi)單程最長(zhǎng)通勤時(shí)耗不應(yīng)超過(guò)1.5小時(shí),采用地鐵或市域鐵路制式支撐空間拓展最大半徑在40~60 km范圍內(nèi),超大城市都市區(qū)范圍在7 000 km~2左右,特大城市都市區(qū)范圍在3 500 km~2左右。為壓縮出行時(shí)耗,提高通勤效率,應(yīng)加強(qiáng)交通與用地系統(tǒng)耦合開(kāi)發(fā),提高接駁系統(tǒng)規(guī)劃設(shè)計(jì)水平,整體提高出行鏈組織效率,保證出行時(shí)耗最小化。
[Abstract]:Domestic mega-cities have entered the stage of metropolitan development, but the relevant theories are relatively lagging behind. It is advantageous to make urban policies scientifically, reserve planning facilities and promote the healthy development of metropolitan areas by studying the spatial scale of metropolitan areas in China. From the point of view of travel time consumption, this paper analyzes and sums up the development history and current characteristics of metropolitan areas in developed countries, and discusses the spatial scale of metropolitan areas in China by combining the present development situation of metropolitan areas such as Beijing and Shanghai and the characteristics of commuting time consumption. The conclusion of the study proves that rail transit should be the main supporting mode in the urban space expansion of big cities in China. Although the travel efficiency of car mode is high, the marginal cost is high, which is not suitable for the characteristics of high-intensity development of Chinese cities. Under the condition of rail network, from the point of view of travel time consumption, it is proposed that the maximum commuting time should not exceed 1.5 hours in the metropolitan area, and the maximum radius of the support space of subway or municipal railway is within 4060 km. The metropolitan area is about 7 000 km~2 and the metropolitan area is about 3 500 km~2. In order to reduce travel time consumption and improve commuting efficiency, the coupling development of traffic and land use system should be strengthened, the planning and design level of connection system should be improved, the efficiency of travel chain organization should be improved as a whole, and the travel time consumption should be minimized.
