【摘要】：[目的]区域土地利用均衡度的时空差异是优化土地利用结构的重要依据,通过对海南省土地利用均衡度的时空差异研究,为优化海南省土地空间配置提供借鉴。[方法]GIS空间分析法、极值标准化法、算术平均法和几何平均法。[结果]海南省土地利用均衡度指数由2010年的0.661逐渐增加到2014年的0.761,土地利用均衡度呈现从一般均衡到优质均衡的发展态势;从各市县的对比分析来看,6个市县处于均衡状态,12个市县处于失衡状态。[结论]土地利用处于均衡状态的市县位于海南省东南部和西北部,开发不足失衡的市县位于海南省中部和西部,过度开发失衡的市县位于海南省北部;土地利用开发强度呈现中部-西部-东部递增的态势,土地利用供给能力呈现中部-西部-东部递减的态势,各市县土地空间配置应结合其开发强度与供给能力以及各地经济状况及城市职能定位,进行合理开发利用,加强中西部的发展,促进全省土地利用均衡发展。
[Abstract]:[Objective] the spatio-temporal difference of regional land use equilibrium is an important basis for optimizing land use structure. Through the study of spatial and temporal differences of land use equilibrium in Hainan Province, it can be used as a reference for optimizing land spatial allocation in Hainan Province. [Methods] GIS space analysis method, extremum standardization method, arithmetic average method and geometric average method. [Results: the land use equilibrium index of Hainan Province gradually increased from 0.661 on 2010 to 0.761 on 2014. The land use equilibrium showed a trend of development from general equilibrium to high quality equilibrium. From the comparative analysis of each city and county, 6 cities and counties are in equilibrium and 12 cities and counties are out of balance. [Conclusion: the cities and counties in the equilibrium of land use are located in the southeast and northwest of Hainan Province, the cities and counties with underdeveloped imbalance are located in the central and western part of Hainan Province, and the cities and counties with over-exploitation imbalance are located in the northern part of Hainan Province. The intensity of land use and development is increasing gradually from central to west to east, and the supply capacity of land use is decreasing from central to west to east. The allocation of land space in cities and counties should be combined with their development intensity and supply capacity, as well as the economic situation and the orientation of urban functions, so as to carry out rational development and utilization, strengthen the development of central and western regions, and promote the balanced development of land use in the whole province.
