摘要: 以县域为研究单元,采取数理统计和重心模型法分析1998~2017年湖北省土地整治项目的时空分异特征;基于整治强度、整治潜力和整治难度等土地整治实施的核心指标,借助耦合协调度模型,综合评判1998~2017年湖北省土地整治实施的协调性。结果表明:(1)1998~2017年湖北省土地整治总体呈现出上升的发展态势,投资规模、建设规模、新增耕地规模和项目数量均表现为先快速增长后有所回落最后趋于平稳的特点,在空间分布上表现为鄂中平原地区高,鄂东和鄂西地区较低的格局特征。(2)1998~2017年湖北省土地整治项目各实施要素的重心均位于江汉平原腹地,并在天门市-钟祥市-京山县一带呈波动式变化。(3)1998~2017年湖北省土地整治项目实施协调度呈现低度耦合协调、中度耦合协调和高度耦合协调3种状态,低度耦合协调状态主要集中在鄂北和鄂东低丘岗地区,高度耦合协调状态主要分布在鄂中平原地区,中度耦合协调状态分布较广,全省范围内均有覆盖。对区域土地整治项目时空格局特征及其实施协调性研究可为新时期我国统筹区域土地整治事业发展及实施差别化管控策略提供有益参考。

Abstract: Based on mathematical statistics and barycenter model, we explored the spatial-temporal differentiation features of land consolidation at the county level of Hubei province from 1998 to 2017. By taking the core indicators of land consolidation implementation, such as consolidation intensity, consolidation potential and consolidation difficulty, we also evaluated the coordination of land consolidation implementation in Hubei province from 1998 to 2017 by using the coupling coordination degree model. The research results showed that:(1) From 1998 to 2017, the land consolidation in Hubei Province showed an overall upward trend. The scale of investment, the scale of construction, the scale of new cultivated land, and the number of projects all showed the characteristics of slowing down and stabilizing after rapid development. In the aspect of spatial distribution, it showed the characteristic of high distribution in central plain of Hubei Province, low in eastern and western Hubei Province.(2)The gravity centers of each implementation element for land consolidation projects were all located in the hinterland of Jianghan plain and present a fluctuating change in the area of Tianmen city-Zhongxiang city-Jingshan county.(3)The implementation coordination degree of land consolidation projects presented three states: low coupling coordination, moderate coupling coordination and high coupling coordination from 1998 to 2017 in Hubei province. The low coupling coordination state is mainly concentrated in the low hilly areas in the north and east of Hubei province, and the high coupling coordination state is mainly concentrated in the central plains of Hubei province. While the moderate coupling coordination state is widely distributed, covering the whole province. Finally, the analysis of spatial-temporal pattern characteristics and implementation coordination of regional land consolidation projects can provide decision-making basis to coordinate the development and implement differentiated control of regional land consolidation in the new era of China.
