【摘要】：榆林地處黃土高原與毛烏素沙漠過(guò)渡帶,是國(guó)家歷史文化名城和國(guó)家能源化工基地的重要組成部分,城市空間沿榆溪河帶狀組團(tuán)式發(fā)展,至2010年,城市建成區(qū)規(guī)模達(dá)52平方公里,較1949年擴(kuò)大13倍。在快速城市化進(jìn)程中,如何可持續(xù)發(fā)展,需對(duì)榆林城市空間演變規(guī)律進(jìn)行研究,為城市適宜性發(fā)展提供理論依據(jù)。本文以榆林城市空間的演變作為研究對(duì)象,通過(guò)文獻(xiàn)引證、歷史考察、空間分析等方法,梳理榆林城市演變背景,在時(shí)間序列上劃分城市發(fā)展階段,研究城市空間結(jié)構(gòu)的階段性特征、影響因素、發(fā)展模式及成因,把握榆林城市空間演變總體特征和機(jī)理,提出榆林城市空間發(fā)展對(duì)策。從城市空間發(fā)展地理基礎(chǔ)、城市建制沿革、城市建設(shè)歷程、社會(huì)經(jīng)濟(jì)發(fā)展及城市規(guī)劃控制等方面入手,將榆林城市空間演變歷程劃分為四個(gè)階段。第一階段為單中心集聚階段(1949年——1969年),城市建設(shè)局限在城廓內(nèi),居住、商業(yè)、工業(yè)企業(yè)、辦公機(jī)構(gòu)等集聚;第二個(gè)階段為單中心軸向拓展階段(1970年——1979年),城市中心在老城區(qū),城市建設(shè)沿榆溪河?xùn)|側(cè)帶狀延伸,隨著工業(yè)發(fā)展恢復(fù),城市功能突破城廓向南、東拓展,工廠、企事業(yè)單位等在榆林老城南部沿城市主干道集聚形成南郊工業(yè)區(qū),東沙新城緊鄰老城區(qū)東部建設(shè),城市空間結(jié)構(gòu)呈“一心三組團(tuán)”格局;第三階段為單中心跨越發(fā)展階段(1980年——1999年),由于城市東部黃土溝壑區(qū)用地適宜性差的限制和西部生態(tài)環(huán)境的改善,城市用地跨越榆溪河向西發(fā)展形成西沙新城,南郊工業(yè)區(qū)和東沙新城區(qū)規(guī)模擴(kuò)大,舊城區(qū)中心地位依舊,城市空間結(jié)構(gòu)呈“一心四組團(tuán)”格局。第四個(gè)階段為多中心組團(tuán)發(fā)展階段(2000年至今),經(jīng)濟(jì)開(kāi)發(fā)區(qū)初具規(guī)模,西沙組團(tuán)規(guī)模擴(kuò)大,空港新城啟動(dòng)建設(shè),舊城更新,為城市文化中心,行政機(jī)構(gòu)西遷,西沙行政中心形成,經(jīng)濟(jì)開(kāi)發(fā)區(qū)成為城市新的經(jīng)濟(jì)中心,城市空間結(jié)構(gòu)呈“三心六組團(tuán)”格局。榆林城市空間演變總體呈現(xiàn)“帶狀延伸,組團(tuán)生長(zhǎng)”的特征,發(fā)展模式經(jīng)歷了單中心集聚到多中心組團(tuán)式發(fā)展的演變歷程,各時(shí)期受自然地理環(huán)境、經(jīng)濟(jì)發(fā)展水平、交通運(yùn)輸條件、政策與規(guī)劃控制、城市職能規(guī)模和社會(huì)文化的影響,城市空間拓展表現(xiàn)為蔓延與跳躍相結(jié)合的特征。在發(fā)展中,應(yīng)以合理的用地結(jié)構(gòu)、區(qū)域生態(tài)安全、文脈傳承和可持續(xù)發(fā)展為目標(biāo),建構(gòu)城市空間發(fā)展策略。
[Abstract]:Yulin is located in the transitional zone between the Loess Plateau and the Maowusu Desert. It is an important part of the national historical and cultural city and the national energy and chemical industry base. The scale of urban built-up area is 52 square kilometers, which is 13 times larger than that of 1949. In the process of rapid urbanization, it is necessary to study the law of urban spatial evolution in Yulin. This paper takes the evolvement of Yulin urban space as the research object, combs the background of Yulin city evolution through the methods of literature citation, historical investigation, spatial analysis and so on. In time series, it divides the stage of urban development, studies the stage characteristics, influencing factors, development models and causes of urban spatial structure, and grasps the overall characteristics and mechanism of urban spatial evolution in Yulin. This paper puts forward the countermeasures for the development of urban space in Yulin, starting with the geographical basis of urban spatial development, the evolution of urban system, the course of urban construction, the development of social economy and the control of urban planning, etc. The evolvement of Yulin urban space is divided into four stages. The first stage is single center agglomeration stage (1949-1969), the urban construction is confined to the city profile, residential, commercial, industrial enterprises, office agencies, etc. The second stage is the unicentral axial extension stage (1970-1979). The urban center is in the old urban area. Urban construction extends along the eastern side of the Yuxi River. As industrial development resumes, the urban function breaks through the city profile south, east, and factories. Enterprises and institutions in the southern Yulin city along the main city along the main road gathered to form a southern suburb industrial zone, Dongsha New City adjacent to the eastern part of the old urban construction, the urban spatial structure of the "one mind three groups" pattern; The third stage is the stage of single-center leapfrogging development (1980-1999). Due to the limitation of land suitability in the loess gully region in the eastern part of the city and the improvement of the ecological environment in the west, the urban land has developed westward across the Yuxi River to form Xisha New City. The scale of the industrial zone in the south suburb and the new district of Dongsha is enlarged, the central position of the old city remains the same, and the urban spatial structure presents the pattern of "one mind, four groups". The fourth stage is the development stage of multi-center group (from 2000 to now, the economic development zone is beginning to take shape). The Xisha regiment has expanded in scale, the construction of the new airport city has been started, the old city has been renewed, the city cultural center, the administrative agency has moved westward, the Xisha administrative center has formed, and the economic development zone has become the new economic center of the city. The urban spatial structure presents the pattern of "three centers and six groups". The urban spatial evolution of Yulin has the characteristics of "band extension, cluster growth", and the development pattern has experienced the evolution course from single center agglomeration to multi-center cluster type development. Affected by the natural geographical environment, economic development level, transportation conditions, policy and planning control, urban functional scale and social culture, urban spatial expansion is characterized by the combination of spread and jump. The strategy of urban spatial development should be constructed with the aim of rational land structure, regional ecological security, cultural heritage and sustainable development.
