摘要
研究目的:对三生空间结构和格局的多维多尺度计量与演化特征分析有助于识别国土空间功能类型的空间分异规律。研究方法:选取长江经济带中部典型省域湖北省作为案例地区,采用格网分析、空间自相关分析和三角图分析法剖析三生空间分布格局和演化特征。研究结果:(1)湖北省三生空间格局与功能演化呈现明显的地域差异,生产空间和生活空间扩张明显,生态空间明显萎缩;(2)三类空间在多个尺度上都表现出较强的空间自相关特性,空间聚集特征明显,在研究期内空间自相关指数有所下降,表明空间破碎度上升;(3)三生空间结构变动特征表现为生产空间和生活空间比例提高、生态空间比例明显降低,但重点开发区、农业主产区和重点生态功能区变动幅度逐次下降。研究结论:应在主体功能区规划政策基础上,加强空间管制措施,促进三生空间融合,并加强生态空间保护。
The purpose of this paper is to explore the spatial disparities of land use function by measuring the composition and structure of the production, living and ecological space（PLES） at multiple scales and from multiple dimensions as well as characterizing its evolution pattern. Taking Hubei Province as a case, the spatial pattern and evolution characteristics of the PLES in the study area was analyzed by using grid analysis, spatial auto-correlation analysis and ternary plot method. The results are as follows. 1）There was great regional diversity in the evolution characteristics of the PLES of Hubei Province. Production space and living space presented prominent expansion and ecological space was shrinking. 2）The spatial cluster of PLES was discovered at multiple scales with the high spatial auto-correlation index. However, the fragmentation of PLES turned to be increasing suggested by the declining auto-correlation index during the study period. 3）The proportions of the production and living spaces increased and the proportion of ecological space decreased, the change ranges of which in the key development zones,the main agricultural production zones and the key ecological function zones declined in turn. In conclusion, the space control measures should be enhanced based on the Major Function Oriented Zoning policy, the integration of PLES should be promoted and the ecological space should be strictly protected.
