新型城镇化背景下的城市居住用地集约利用评价研究——以福清市为例

目的]从微观层次对城市居住用地集约利用评价,为城市居住用地的合理布局和提高居住用地集约利用提供依据。方法]选取土地利用程度、土地投入水平、土地利用效率中3个层次的5个指标,运用多因素综合评价法、特尔斐法等进行数据处理和综合评价。结果]福清市154个居住功能区中,有4个过度利用功能区,土地面积为29.02 hm2;8个集约利用功能区,土地面积82.83 hm2;86个中度利用功能区,土地面积876.76 hm2;56个低度利用功能区,土地面积349.36 hm2。总体上福清市城市居住用地集约利用水平属于中度利用水平。结论]随着城镇化速度的加快,城市居住用地供需矛盾越来越突出,调整土地利用结构和提高集约节约利用水平势在必行,因此,必须从规划源头、深度挖潜、严格标准、优化结构4个方面促进城市居住用地合理布局和集约利用。

Research on Evaluation of Urban Residential Land Intensive Use in the Context of New Urbanization： A Case Study in Fuqing

Objective ] The intensive use of urban residential land was evaluated from the micro level, which will provide a reference for rea- sonable layout of urban residential land and intensive land use. Method] Selecting three evaluation system of land use intensity, land invest- ment and land use efficiency to deal with data and evaluate integratedly. The methods include multi-factor comprehensive evaluation and Del- phi method. Result] The results showed that there were 4 functional areas over used which was 29.02 hm2 , 8 functional areas intensively used which was 82.83 hm2 , 86 functional area moderately used which was 876.76 hm2 and 56 functional areas lowly used which was 349.36 hm2. In general, the level of urban residential intensive land use in Fuqing belongs to the moderate level. Conclusion] It was concluded that with the faster pace of urbanization, the contradiction between urban residential land supply and demand was increasingly serious, thus adjus- ting structure of land use and improving the intensive utilization level of urban residential land was inevitable. This paper puts forword sugges- tions from the planning source, exploiting potential deeply, stricting land use standard and optimizing structure of land use to promote the rea- sonable layout and intensive land use.
