福建省土地利用空间均衡度时空分异及驱动力研究

Research on Spatial-Temporal Characteristics andDriving Forces of Spatial Balance Degrees on Land Use in Fujian Province

土地利用空间均衡度反映土地开发强度和供给能力的适配状况,为了进一步优化国土空间布局,有必要对其展开深入研究.以福建省9个设区市为研究对象,运用指数模型和趋势面分析法分析2008年~2018年间的土地利用空间均衡度的时空分异特征并用灰色关联分析模型对其驱动力进行探究.研究结果表明,在2008年~2018年间,福建省的土地利用空间均衡度总体呈上升态势,土地利用空间均衡状态由失衡转为基本均衡;土地利用空间均衡度各地区差异明显,东西方向差异缩小,南北方向差异拉大;土地利用空间均衡度是经济、社会和自然多方面综合作用的结果,受经济密度影响最为显著,人口、土地利用和资源生态等因素对土地利用空间均衡有重要影响,环境承载力对其有重要制约作用.

To optimize the spatial distribution of land,it is necessary to study the spatial balance degrees onland use,which reflects the adaptability of land development intensity and supply capacity.The paper used meth-ods of index model,analysis of trend surface and Grey relative analysis model to study the situation of spatial bal-ance degrees and its driving forces on land use from 2008 to 2018 in Fujian province.The result shows that asteady upward trend in fluctuations and the situation of spatial balance on land use improved from imbalancedbasically balanced;spatial balance degrees on land use has a big difference between areas and is in uneven dis-tribution;the difference of them in east-west is shrinking but is expanding in south-north.The spatial balance ofland use is the result of the comprehensive effect of economy,society and nature;and it is most affected by eco-nomic densit;population,situation of land use,resource and ecology are important factors in the spatial balanceof land use and environmental carrying capacity has an important restrictive effect on it.
