【摘要】：我国处于城市快速发展时期,城市的数量和规模增长迅速,考虑到我国人多地少的基本国情,导致城市土地利用问题突出,在这种背景之下,对城市土地的集约利用研究应运而生。在我国的土地所有制中,城市土地归国家所有,具有很强的垄断性。土地市场在不同地区表现的区位差异性显著,土地资源的稀缺性强,而城市化发展离不开土地的支持,这样土地集约利用也就非常必要。对城市土地集约利用的定位,以及对城市化本质的认识,分析两个概念之间的相关性,能对城市的发展有良好的促进作用。四川省作为西南地区经济、交通枢纽,二元经济结构明显,技术水平落后,城市化发展水平低于东部发达地区,城市发展土地需求量大,为推进区域的经济发展,通过集约地利用土地,可以实现经济社会与土地利用之间的协调发展。以四川省的18个地级市为研究对象,分别构建城市化、土地集约利用两个评价指标体系,分析四川区域内不同城市的真实发展水平。城市化区域发展差距先增大后变小,其中,区域整体城市化水平随时间变化为上升趋势,以中心城市(成都)为最高值,随距离增加有变小的趋势,内江、眉山、巴中、资阳城市化水平最低。区域差异性在土地集约利用水平中表现得非常突出,为川中地区川南地区川北地区。通过物理学上的交互耦合机制,构建耦合协调发展模型,并根据得到的耦合协调度将城市发展水平分类,便于进行空间相关性分析。出现以成都市为中心的密集耦合高值区,北部与南部耦合协调发展较好,东北部和东南部区域发展相对较弱。对全局空间相关性进行分析,得到的莫兰值均为负值,且由初期强负相关性,逐渐发展接近随机性分布,表明空间差异性减弱。对局部相关性进行分析,以巴中和达州为中心的四川东北部出现耦合协调发展的低值聚集区域,需要得到改善。
[Abstract]:China is in the period of rapid urban development. The number and scale of the city are growing rapidly. Considering the basic national conditions of our country, the problem of urban land use is prominent. Under this background, the intensive use of urban land has come into being. In the land ownership system of our country, the urban land is owned by the state and is very strong. The land market has a significant location difference in different regions, the land resources are scarce, and the development of the urbanization can not be separated from the support of the land, so the intensive use of the land is also necessary. The orientation of the intensive use of the urban land, the understanding of the nature of the urbanization and the correlation between the two concepts can be used to the city. The development of the city has a good promotion effect. As the economy of the southwest region, the transportation hub, the two yuan economic structure is obvious, the technical level is backward, the level of the urbanization development is lower than the eastern developed area, the demand of the urban development land is large, in order to promote the economic development of the region, the economic and social and land can be realized through the intensive use of land. Using the coordinated development between the 18 cities of Sichuan Province as the research object, two evaluation indexes system of urbanization and intensive land use are constructed respectively, and the real development level of different cities in the Sichuan region is analyzed. The regional development gap of urbanization is increased first and then then smaller, in which the overall Urbanization level of the region is rising with time. The trend is that the central city (Chengdu) is the highest, and the trend is smaller with the distance. The urbanization level of Neijiang, Meishan, Bazhong and Ziyang is the lowest. The regional difference is very prominent in the level of land intensive use, which is a coupling and coordinated development through the interaction mechanism of physics in the North Sichuan area. According to the obtained coupling coordination degree, the urban development level is classified and the spatial correlation analysis is easy to be carried out. The dense coupled high value area with Chengdu as the center appears, the coupling and coordination between the north and the south is better, and the regional development in the northeast and the southeast is relatively weak. For negative value, and from initial strong negative correlation, it gradually develops close to random distribution, which indicates that the spatial difference is weakened. Local correlation is analyzed, and the low value aggregation region in the northeast of Sichuan, Bazhong and Dazhou as the center, needs to be improved.
