摘要 以宁德市为研究区,采用多因素综合评价法,对研究区建设用地集约度进行测算,判定研究区土地利用状况类型,在此基础上分析了研究区各县市区集约度空间分异规律。结果表明:从宁德市辖区整体来看,计算的宁德市集约度为77.74,集约度较高。从宁德市各县市区来看,福鼎市集约度最高,集约度较高的有蕉城区、柘荣县、福安市和霞浦县,集约度中等的有周宁县、屏南县和寿宁县,古田县集约度最低。从各指数的计算结果来看,宁德市各县市区用地弹性指数(EI)均较低,该指标是宁德市集约度进一步提高的最主要限制性因素。

Abstract Taking Ningde City as the research area, multiindex comprehensive evaluation method is used to calculate the intensive degree of construction land in the research area, and on this basis, the spatial differentiation law of the intensive degree of each county and city is analyzed. The results show that: from the perspective of the city as a whole, the intensive degree of Ningde City is 77.74;the comparative analysis of the intensive degree of the counties and cities show that the highest intensive degree city is in Fuding City among all counties and cities, the lowest intensive degree is in Gutian County. The cities ranked from high intensive degree to low are Fuding City, Jiaocheng District, Zherong County, Fuan City, Xiapu County, Zhouning County, Pinnan County, Shouning County, and Gutian County. According to the calculation results of the indexes, the land elasticity index (EI) of Ningde City is low, which is the main limiting factor to further improve the intensive degree of Ningde City.

近年来,随着我国经济快速发展,城市化水平不断提高,全国各地均存在建设用地规模扩张过快,土地闲置和低效利用等现象,土地资源日渐短缺,人地矛盾日益严重[1-4]。在此背景下,2014年原国土资源部下发《国土资源部关于推进土地节约集约利用的指导意见》(国土资发〔2014〕19号),对大力推进土地集约利用提出了新要求[5-6]。国内学者在全国各地开展了大量相关研究[7-10]。张俊峰等[11-12]采用综合因素评价法和压力-状态-响应(PSR)法,开展城市建设用地节约集约利用评价实例研究。张俊平等[13]采用测度模型对广东省紫金县建设用地集约潜力进行测算。已有的研究成果[14-15]大多是对某些地区进行集约度的整体评价,较少從空间上分析其影响因素和分布规律。……
