内蒙古中部城市土地利用绩效及其障碍因素

目的]评价内蒙古中部城市土地利用绩效,并分析其障碍因子,为提高该地区土地利用效率,合理调配和利用土地资源提供科学依据。方法]结合中国西北部地区自然环境特点,从土地利用结构、土地利用程度和土地利用效益3个方面构建内蒙古中部呼包鄂3个城市土地利用绩效评价体系;运用TOPSIS方法和障碍度模型测算2004—2013年呼包鄂城市的土地利用综合、单项绩效水平和影响呼包鄂土地利用绩效障碍因子。结果]2004—2013年内蒙古中部城市呼包鄂的土地利用综合绩效总体呈上升趋势,但土地利用绩效具有明显的差异性,呼和浩特市上升较快,包头市较平稳,颚尔多斯市较慢;土地利用结构和土地利用社会效益是主要的障碍因子。结论]内蒙古中部城市土地利用综合绩效与目标区域的资源禀赋及政策实施密不可分,应加大土地的资本投入,加强城市公共设施建设和土地利用的社会效益,完善和优化土地利用结构以及提高土地利用深度和广度;同时,内蒙古中部城市之间有着密切的经贸和社会联系,其土地利用应从一体化角度去完善,形成产业聚集,促进整体的土地资源优化。

Land Utilization Performance and Obstacle Factors for Cities in Central Inner Mongolia Region

Objective] The objective of this paper was to evaluate land utilization performance and analyze obstacle factors and to provide scientific basis for the improvement of urban land utilization efficiency and allocation of land resource reasonably.Methods] An indicator system of land utilization performance evaluation, especially for the northwestern region of China, was set up in consideration of local natural environment characteristics. The system mainly had topics of land utilization structure, land utilization degree and land utilization efficiency. The level of urban land utilization performance and the obstacle factors of land utilization were measured based on the data of Hohhot-Baotou-Ordos from 2004 to 2013 using TOPSIS and the model of land utilization obstacle degree.Results] Research showed that the performance of land utilization of Hohhot-Baotou-Ordos was ascending differently. The performance of land utilization of Hohhot went steadily up. Baotou was stable and Ordos was slower. The main obstacle factors were land utilization structure and social benefits of land utilization.Conclusion] The performance was closely related to the amount of endowment resources and policy implementation. This paper advised that cities of Central Inner Mongolia should strengthen the urban public facilities and social benefits, optimize the land use structure, and improve land use intensive degree. Cities in central Inner Mongolia have close economic, trade and social intrinsic ties. Land utilization should be improved based on cities integration to form industrial agglomeration and promote the optimization of land resources as a whole.
