【摘要】：在快速城镇化的背景下,我国城市空间开始出现无序扩张的趋势,耕地数量快速减少,城市生态环境快速恶化,严重影响城市未来的可持续发展能力。为了促进城市土地的集约利用,改善城市生态环境,保障城市粮食供应,需要对城市空间的开发规模进行控制,划定城市开发边界,合理引导城市空间有序发展。城市开发边界是抑制城市蔓延,引导城市空间有序发展的重要举措,现已经成为城市规划领域的研究热点,从城市开发边界的起源到我国的引入与实践都有大量的研究。为了丰富城市开发边界的划定研究,同时探索出一个合理可行的划定方法,本文以徐州都市区为研究区域,利用扩张强度指数和等扇分析法对徐州建成区的城市空间演变进行分析,得到不同时段和不同方位上的徐州建成区的扩张强度;然后对建成区的蔓延状态进行分析,根据得出的结论并结合建成区的空间演变趋势,确定徐州城市空间扩张所处的阶段以及未来的扩张方向和扩张强度,最终发现:徐州处于快速城市化的阶段,扩张强度较高,扩张方向主要为东向和东南向,同时城市空间处于蔓延发展的状态,基于此,需要对徐州的城市空间扩张进行控制,划定出徐州都市区的城市开发边界。根据徐州煤炭资源枯竭型城市的特点,最终选择从生态保护的视角进行城市开发边界的划定,为了更好的全面的划定出徐州都市区的城市开发边界,在进行生态安全性评价的同时,也参考了徐州都市区的交通区位和社会经济条件;而在进行生态安全性评价的过程中,创新性的引入生态空间可占用性评价模型。最终根据徐州都市区的生态安全性评价,结合交通区位评价和社会经济区位评价,利用最小累积阻力模型,对徐州都市区的建设用地进行适宜性评价,并以此划定出徐州都市区的城市开发边界,同时提出相应的管理策略,期望能够为其他相似城市的开发边界划定工作提供一些经验与借鉴。
[Abstract]:Under the background of rapid urbanization, the urban space in our country began to expand disorderly, the amount of cultivated land decreased rapidly, and the urban ecological environment deteriorated rapidly. In order to promote intensive utilization of urban land, improve urban ecological environment and ensure urban food supply, it is necessary to control the scale of urban space development and delineate urban development boundaries. The boundary of urban development is an important measure to restrain the spread of the city and guide the orderly development of urban space, which has become the research hotspot in the field of urban planning. From the origin of urban development boundary to the introduction and practice of our country, there has been a lot of research. In order to enrich the study of urban development boundary delimitation and explore a reasonable and feasible method, this paper takes Xuzhou metropolitan area as the research area. This paper analyzes the urban spatial evolution of Xuzhou's built-up area by using the expansion intensity index and isopan analysis method, and obtains the expansion intensity of Xuzhou's built-up area in different time periods and different directions, and then analyzes the spreading state of the built area. According to the conclusion and the spatial evolution trend of the built area, the stage of urban spatial expansion in Xuzhou, the direction and intensity of urban expansion in the future are determined. Finally, it is found that Xuzhou is in the stage of rapid urbanization, and the expansion intensity is high. The direction of expansion is mainly eastward and southeastward, while urban space is in the state of spreading and developing. Based on this, it is necessary to control the expansion of urban space in Xuzhou. According to the characteristics of Xuzhou coal resource exhausted city, we choose to delimit the urban development boundary from the angle of ecological protection. In order to delineate the urban development boundary of Xuzhou metropolitan area better and more comprehensively, the ecological security evaluation is carried out, and the traffic location and social and economic conditions of Xuzhou metropolitan area are also referred to. And in the process of ecological security evaluation, Finally, according to the ecological security evaluation of Xuzhou metropolitan area, combined with traffic location evaluation and socio-economic location evaluation, the minimum cumulative resistance model is used. This paper evaluates the suitability of the construction land in Xuzhou metropolitan area, and draws the urban development boundary of Xuzhou metropolitan area, and puts forward the corresponding management strategy. It is expected to provide some experience and reference for other similar cities.
