河北省城市土地集约利用潜力评价方法探讨

Evaluating Intensive Use of Urban Land in Hebei Province

我国土地资源短缺,城市化初始阶段非农建设用地扩张严重,与此同时,城市存量土地却存在粗放利用现象,因此,必须挖掘城市用地潜力,提高土地使用效率,实现城市土地集约利用。本文以河北省为例,首次针对全省范围内不同规模城市(地级市、县级市、县城),采用“同质异量”的指标合理值,从宏观上评价全省城市土地集约利用潜力,划分出集约利用、适度利用、低度利用和粗放利用4种类型,并对评价结果进行了分析,探索了河北省城市土地集约利用水平的区域分异规律,提出自然条件、区位条件和经济发展水平是影响河北省城市土地集约利用潜力的重要因素。文章从理论和方法上对河北省城市土地集约利用潜力的评价方法进行了一些探讨性的研究,划分的潜力级别对河北省宏观调控城市建设发展和土地利用方向有一定的实用价值和指导意义。

China is one of the countries short of land resources. agricultural sectors in the preliminary stages of the urbanization lands in urban area are used extensively and inefficiently. It Expanding pieces of land are used in nonprocess. On the other hand, the remaining is urgent to exploit latent potentiality and achieve higher efficiency of land use. Taking Hebei province as an example, the paper evaluates for the first time the intensive land use in cities of different sizes and scales in the whole province. In a macro manner, the urban land use in the province was classified into such three types as intensive use, proper use, lower use and extensive use. It also explores the rules of the land use potentiality grade in different cities of Hebei province, concluding with the fact that the natural conditions, location convenience and the economic development levels are important factors that affect the intensive land use potentiality of Hebei province. Compared with the potential evaluation system in the past which focused on the uniformity and singularity of city land use, it benefits the macro-regulation of the construction development and utilization structure of urban land use and provides a premise for urban planning, reconstruction and renewing of the deserted urban areas, optimizing the land use patterns, improving the land use efficiency, and achieving the sustainable development of the urban land use. It also makes a thorough study of the evaluation methods of the intensive use of urban land. The classification of land use potential is practically valuable and significant for the macro regulation of the land use.
