激活觸媒節(jié)點(diǎn)

在現(xiàn)代交通系統(tǒng)的支撐下，高鐵站點(diǎn)及其周邊不再是單一的交通集散空間，而是整合交通、商業(yè)、商務(wù)、文化娛樂(lè)、會(huì)展、信息服務(wù)的城市新型功能混合區(qū)，并成為新的社會(huì)經(jīng)濟(jì)與文化交流中心，是重構(gòu)城市空間結(jié)構(gòu)與展現(xiàn)城市空間特色的重要機(jī)遇。一方面，站城地區(qū)作為城市重大工程項(xiàng)目，具有塑造新時(shí)期城市空間骨架的觸媒作用。然而，目前已經(jīng)存在的大量新城建設(shè)、不斷涌現(xiàn)的各種綜合服務(wù)中心、老城中心的更新與復(fù)蘇等，如何協(xié)同它們之間的平衡發(fā)展關(guān)系成為站點(diǎn)地區(qū)開(kāi)發(fā)的難題。另一方面，站城地區(qū)作為與其他城市聯(lián)系的門(mén)戶(hù)，擔(dān)負(fù)著展示城市空間特色的窗口作用。但以往的規(guī)劃設(shè)計(jì)一味地追求站房的雄偉和標(biāo)志性，追求廣場(chǎng)或軸線的氣派，缺乏地域和地方的特點(diǎn)，既造成了投資上的浪費(fèi)，還給旅客的出行帶來(lái)了不便，如何協(xié)調(diào)站點(diǎn)地區(qū)與其他地區(qū)的尺度、風(fēng)貌、交通等空間關(guān)系也應(yīng)受到重視。

空間基因研究為以上問(wèn)題提供了新的解決思路。基于城市尺度的空間基因，可以在城市總體層面上對(duì)站點(diǎn)地區(qū)及其他地區(qū)進(jìn)行整合和協(xié)調(diào)，梳理城市整體空間秩序；基于街區(qū)尺度的空間基因研究，可以將本土空間組合模式與綜合交通樞紐站房、商業(yè)商務(wù)地塊、集散廣場(chǎng)、景觀軸線等空間要素有機(jī)融合，強(qiáng)化尺度與風(fēng)貌的控制引導(dǎo)，創(chuàng)造形象與功能兼?zhèn)涞脑诘匦詷屑~核心區(qū)，由此實(shí)現(xiàn)站點(diǎn)地區(qū)與城市整體空間效益的雙贏。以下以南京站、南京南站、蘇州站為例進(jìn)行介紹?！?/p>

With the support of the modern transportation system, the high-speed railway station and its surroundings are no longer a single traffic distribution space, but a new urban mixed functional area integrating traffic, commerce, business, culture, entertainment, exhibition and information services, and has become a new social, economic and cultural exchange centre, which is an important opportunity to reconstruct the urban spatial structure and show the urban spatial characteristics.

On the one hand, the station area, as a major urban engineering project, has the catalytic role of shaping the urban spatial structure in the new era.However, how to coordinate the balanced developing relationship between the existing large number of new city construction, the emergence of various comprehensive service centres, and the renewal and recovery of the old city centre has become a complex problem in the development of station areas.On the other hand, as a gateway to connect with other cities, the station area serves as a window to display the characteristics of urban space.However, the previous planning and design blindly pursued the majestic and iconic station buildings,the style of the square or the axis, lacking regional and local characteristics, which not only caused a waste of investment, but also brought inconvenience to the travel of passengers.How to coordinate the spatial relationship between the station area and other areas should also be paid attention to.

The space gene research provides a new way to solve the above problems.Space gene researches based on city scale can integrate and coordinate the station area and other areas at the overall level of the city, and sort out the overall spatial order of the city.Space gene researches based on block scale can organically integrate the local spatial combination model with the spatial elements such as comprehensive transportation hub station buildings, commercial plots, distribution squares, and landscape axes, so as to strengthen the control and guidance of scale and style, and create the core area of local hub with both image and function, thus to achieve the win-win situation between station area and the city's overall space.The following are examples of Nanjing Railway Station, Nanjing South Railway Station and Suzhou Railway Station as examples.□
