【摘要】：榆林地处黄土高原与毛乌素沙漠过渡带,是国家历史文化名城和国家能源化工基地的重要组成部分,城市空间沿榆溪河带状组团式发展,至2010年,城市建成区规模达52平方公里,较1949年扩大13倍。在快速城市化进程中,如何可持续发展,需对榆林城市空间演变规律进行研究,为城市适宜性发展提供理论依据。本文以榆林城市空间的演变作为研究对象,通过文献引证、历史考察、空间分析等方法,梳理榆林城市演变背景,在时间序列上划分城市发展阶段,研究城市空间结构的阶段性特征、影响因素、发展模式及成因,把握榆林城市空间演变总体特征和机理,提出榆林城市空间发展对策。从城市空间发展地理基础、城市建制沿革、城市建设历程、社会经济发展及城市规划控制等方面入手,将榆林城市空间演变历程划分为四个阶段。第一阶段为单中心集聚阶段(1949年——1969年),城市建设局限在城廓内,居住、商业、工业企业、办公机构等集聚;第二个阶段为单中心轴向拓展阶段(1970年——1979年),城市中心在老城区,城市建设沿榆溪河东侧带状延伸,随着工业发展恢复,城市功能突破城廓向南、东拓展,工厂、企事业单位等在榆林老城南部沿城市主干道集聚形成南郊工业区,东沙新城紧邻老城区东部建设,城市空间结构呈“一心三组团”格局;第三阶段为单中心跨越发展阶段(1980年——1999年),由于城市东部黄土沟壑区用地适宜性差的限制和西部生态环境的改善,城市用地跨越榆溪河向西发展形成西沙新城,南郊工业区和东沙新城区规模扩大,旧城区中心地位依旧,城市空间结构呈“一心四组团”格局。第四个阶段为多中心组团发展阶段(2000年至今),经济开发区初具规模,西沙组团规模扩大,空港新城启动建设,旧城更新,为城市文化中心,行政机构西迁,西沙行政中心形成,经济开发区成为城市新的经济中心,城市空间结构呈“三心六组团”格局。榆林城市空间演变总体呈现“带状延伸,组团生长”的特征,发展模式经历了单中心集聚到多中心组团式发展的演变历程,各时期受自然地理环境、经济发展水平、交通运输条件、政策与规划控制、城市职能规模和社会文化的影响,城市空间拓展表现为蔓延与跳跃相结合的特征。在发展中,应以合理的用地结构、区域生态安全、文脉传承和可持续发展为目标,建构城市空间发展策略。
[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.
