延龙图地区城市空间形态演变研究
发布时间：2018-08-05 09:28
【摘要】：城市空间形态是多种地理要素相互作用的综合结果,这些要素包括地理环境,社会经济发展,自然环境因素以及人类各种活动等。同时城市空间形态也是反映城市社会、经济、文化的综合表征。这一表征,能反映出城市发展的实质。城市空间形态是规划和建设城市的重要根据,其特性直接影响到一系列重大问题。 本研究以延吉市、龙井市、图们市作为研究区域,因为此区域处于吉林省东部。同时它也处于中国、俄罗斯、朝鲜三国的交界区域,地理位置比较特殊。 本文主要研究内容是延龙图地区城市空间形态演变情况。本文通过延龙图三市的土地利用动态变化分析,得出了2001-2011年,延龙图三市各地类土地利用变化的程度；本文在城市空间形态变化对比分析过程中,直观的展现了延吉市、龙井市、图们市城市空间形态变化的方向,并认知了延吉市、龙井市、图们市的城市空间形态类型,本文通过对延龙图地区城市空间形态演变特征的分析,得出了三市的城市空间形态紧凑度和分形维数的变化程度,以及变化趋势。 通过延龙图地区城市土地利用动态变化分析研究,发现2001-2011年延吉市农用地年变化率相对较高,龙井市农用地面积增加幅度最大,主要是由于绿地的转化,水域面积变化相对比较显著；图们市建筑用地面积有少量增加,水域面积有所减少,农用地面积增长的幅度最大,主要来源于绿地的转化。通过延龙图地区城市空间形态变化对比分析研究,发现延吉市主要向东西方向发展,龙井市主要沿省道“延吉-龙井”一级公路以及“龙井-朝阳川”公路向东北方向发展,图们市主要沿302国道向东北、西北方向发展；延吉市城市空间形态类型属于团块状城市形态,龙井市和图们市城市空间形态类型属于线形城市空间形态。通过延龙图地区城市空间形态特征分析研究,发现三市的城市空间形态紧凑度均有所下降,三市的城市外围分形维数均有所上升,其中延吉市的紧凑度指数和分形维数变化幅度最大,说明延吉市的城市形态趋圆性明显降低,.城市周界变得更加复杂。 通过认知城市空间形态的类型,以及量化评价城市空间形态的方法,可以更准确的估计城市空间发展的合理性,为城市发展提供实践的依据和理论的诠释,有助于控制和预测城市的发展。
[Abstract]:Urban spatial form is a comprehensive result of the interaction of many geographical factors, including geographical environment, social and economic development, natural environment factors and human activities. At the same time, the form of urban space is also a comprehensive representation of urban society, economy and culture. This representation can reflect the essence of urban development. Urban spatial form is an important basis for urban planning and construction, and its characteristics directly affect a series of important issues. In this study, Yanji City, Longjing City, Tumen City as the research area, because this region is in the east of Jilin Province. At the same time, it is also located in the border of China, Russia and North Korea, the geographical location is relatively special. The main content of this paper is the evolvement of urban spatial form in Yanlongtu area. Through the dynamic change analysis of land use in Yilongtu three cities, the paper gets the degree of land use change in Yilongtu three cities from 2001 to 2011. In the process of contrast analysis of urban spatial form change, this paper shows Yanji City intuitively. Longjing City, Tumen City, the direction of urban spatial form changes, and the understanding of Yanji City, Longjing City, Tumen City urban spatial form types, this paper through the analysis of the Yilongtu area urban spatial shape evolution characteristics, The change degree and trend of the compact degree and fractal dimension of urban space in the three cities are obtained. Through the analysis of the dynamic changes of urban land use in Yanlongtu area, it is found that the annual change rate of agricultural land in Yanji city is relatively high from 2001 to 2011, and the increase of agricultural land area in Longjing city is the largest, mainly due to the transformation of green space. The change of water area is relatively significant. The area of construction land in Tumen City has a small increase, the area of water area has decreased, and the increase of agricultural land area is the largest, which mainly comes from the transformation of green space. Through the comparative analysis of the changes of urban spatial morphology in Yilongtu area, it is found that Yanji city mainly develops east and west, Longjing city develops mainly along the provincial road "Yanji-Longjing" first class highway and "Longjing-Chaoyang Chuan" highway to the northeast. Tumen mainly develops to the northeast and northwest along the 302 national highway. The urban spatial form of Yanji belongs to the form of blocky city, and the form of urban space of Longjing and Tumen belongs to the linear form of urban space. Through the analysis and study of the urban spatial morphological characteristics in Yanlongtu area, it is found that the compact degree of urban spatial form in the three cities has decreased, and the fractal dimension of the periphery of the three cities has increased. Among them, the compactness index and fractal dimension of Yanji city have the biggest change range, which indicates that the urban form roundness of Yanji city is obviously reduced. The boundaries of the city become more complex. By recognizing the types of urban spatial forms and quantifying the methods of evaluating urban spatial forms, we can more accurately estimate the rationality of urban spatial development and provide practical basis and theoretical interpretation for urban development. It helps to control and predict the development of the city.
