【摘要】：城市空間形態(tài)是多種地理要素相互作用的綜合結(jié)果,這些要素包括地理環(huán)境,社會經(jīng)濟(jì)發(fā)展,自然環(huán)境因素以及人類各種活動等。同時城市空間形態(tài)也是反映城市社會、經(jīng)濟(jì)、文化的綜合表征。這一表征,能反映出城市發(fā)展的實質(zhì)。城市空間形態(tài)是規(guī)劃和建設(shè)城市的重要根據(jù),其特性直接影響到一系列重大問題。 本研究以延吉市、龍井市、圖們市作為研究區(qū)域,因為此區(qū)域處于吉林省東部。同時它也處于中國、俄羅斯、朝鮮三國的交界區(qū)域,地理位置比較特殊。 本文主要研究內(nèi)容是延龍圖地區(qū)城市空間形態(tài)演變情況。本文通過延龍圖三市的土地利用動態(tài)變化分析,得出了2001-2011年,延龍圖三市各地類土地利用變化的程度；本文在城市空間形態(tài)變化對比分析過程中,直觀的展現(xiàn)了延吉市、龍井市、圖們市城市空間形態(tài)變化的方向,并認(rèn)知了延吉市、龍井市、圖們市的城市空間形態(tài)類型,本文通過對延龍圖地區(qū)城市空間形態(tài)演變特征的分析,得出了三市的城市空間形態(tài)緊湊度和分形維數(shù)的變化程度,以及變化趨勢。 通過延龍圖地區(qū)城市土地利用動態(tài)變化分析研究,發(fā)現(xiàn)2001-2011年延吉市農(nóng)用地年變化率相對較高,龍井市農(nóng)用地面積增加幅度最大,主要是由于綠地的轉(zhuǎn)化,水域面積變化相對比較顯著；圖們市建筑用地面積有少量增加,水域面積有所減少,農(nóng)用地面積增長的幅度最大,主要來源于綠地的轉(zhuǎn)化。通過延龍圖地區(qū)城市空間形態(tài)變化對比分析研究,發(fā)現(xiàn)延吉市主要向東西方向發(fā)展,龍井市主要沿省道“延吉-龍井”一級公路以及“龍井-朝陽川”公路向東北方向發(fā)展,圖們市主要沿302國道向東北、西北方向發(fā)展；延吉市城市空間形態(tài)類型屬于團(tuán)塊狀城市形態(tài),龍井市和圖們市城市空間形態(tài)類型屬于線形城市空間形態(tài)。通過延龍圖地區(qū)城市空間形態(tài)特征分析研究,發(fā)現(xiàn)三市的城市空間形態(tài)緊湊度均有所下降,三市的城市外圍分形維數(shù)均有所上升,其中延吉市的緊湊度指數(shù)和分形維數(shù)變化幅度最大,說明延吉市的城市形態(tài)趨圓性明顯降低,.城市周界變得更加復(fù)雜。 通過認(rèn)知城市空間形態(tài)的類型,以及量化評價城市空間形態(tài)的方法,可以更準(zhǔn)確的估計城市空間發(fā)展的合理性,為城市發(fā)展提供實踐的依據(jù)和理論的詮釋,有助于控制和預(yù)測城市的發(fā)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.
