摘要:
开展城市土地集约利用评价，分析其区域变化规律，为宏观指导城市土地资源集约利用，切实实现土地利用方式的转变提供依据。以宝鸡市为研究对象，构建建设用地节约集约利用评价指标体系，采用多因素综合评价法，测算宝鸡市及下辖12个县（区）的集约度水平，判定土地利用类型，并进行空间分异特性研究。结果表明：宝鸡市整体集约度较高，各县（区）存在明显的区域差异性。集约利用水平在空间上呈现中心—外围递减的圈层结构形式，即土地集约度市区 > 郊区 > 郊县，城市中心 > 城市边缘区，中部平原 > 北部山区，城市空间拓展与土地利用之间的耦合性较差。影响区域土地集约利用的因素较为复杂，自然条件和区位条件差异是基底条件，经济发展水平和产业结构是其重要因素。多因素综合评价法测算结果与空间分异特性研究结果基本吻合，符合宝鸡市实际，表明该评价方法适用于城市建设用地集约度测算，具有一定的可行性。
Abstract:
To carry out the evaluation of urban intensive land utilization and analyze the regional changes for providing the basis for the macro guidance of urban intensive land use and the actual implementation of land use changes, we selected Baoji City as the research sample to calculate the intensive utilization level, determine the land use types and analyze the spatial differentiation characteristics of 12 counties in Baoji City by building the index system of intensive use evaluation on construction land and adopting quantitative evaluation method. The results prove that the overall level of intensive utilization in Baoji City is high and there is significant spatial differentiation across various counties. Firstly, the level of intensive utilization presents a circle structure in space, which is diminishing from center to the outside. In other words, the intensive land utilization level in city center is the highest, followed by suburbs, and the level in county is the lowest. So, the level in city center is higher than the urban fringe. In addition, the level of intensive utilization in central plain is higher than the northern mountain area. To sum up, the coupling between urban spatial expansion and land use is poor. Secondly, the factors that affect the intensive land use are more complex according to the study on different spatial characteristics. Natural and regional conditions are the bases and the level of economic development and industrial structure are the important factors affecting the intensive land use. Lastly, results measured by multi-factor comprehensive evaluation method are basically coincided with that estimated by the space differentiation characteristics method, which agrees with practical situation. In conclusion, this research method is suitable for the evaluation of urban land intensive utilization and it has feasibility to some extent.
