摘要
为明晰福建省近10年城市土地集约利用状况和时空分异特征,在构建福建省城市土地集约利用评价体系的基础上,运用熵值法对福建省9个设区市市辖区2008~2017年城市土地集约利用状况进行综合评价分析,并引入变异系数揭示其时空变化特征。结果表明:福建省城市土地集约利用水平整体不高,10年间全省整体城市土地集约利用程度变化不明显;福建省城市土地集约类型存在着明显的等级差异,空间差异随着时间的推移略呈扩大的趋势;在空间分布上,东南部沿海地区城市土地集约利用程度明显高于西北部非沿海地区。
In order to clarify the situation of intensive land use and the characteristics of spatial and temporal differentiation in Fujian Province in recent 10 years,based on the construction of the evaluation system of urban land intensive use in Fujian Province,using the entropy method to comprehensively evaluate the urban land intensive use in 9 municipalities of Fujian Province from 2009 to 2018,and the coefficient of variation was introduced to reveal its spatial and temporal variation characteristics. The results show that the overall level of urban land use in Fujian Province is not high,and the degree of urban land intensive use in Fujian Province has not changed significantly in the past 10 years. Urban land intensification type in Fujian Province has obvious gradation,and the spatial difference tends to expand with the passing of time. In terms of spatial distribution,the intensity of urban land use in eastern coastal areas is significantly higher than that in western non-coastal areas.
