摘要
科学识别生产、生活、生态空间时空演化特征及其内在相互关系,对实现国土空间优化布局和可持续发展具有重要意义。该研究结合多源时空数据,对2000—2020年中国陆域“三生”空间功能进行异质性评价与时空演变分析,揭示了中国市域“三生”空间的聚集性与协调性特征,并据此提出了相应分区调控方案。结果表明:1)中国生产空间功能整体呈现“东高西低、大聚集小分散”的空间格局;生活空间功能呈现沿胡焕庸线两侧东高西低的空间格局;生态空间功能呈现“腹地高沿海低”的格局。2)2000—2020年间中国市域“三生”空间功能呈现较强的聚集性分布特点,且正相关类型以集群形式出现,负相关类型多零星分布于各地。3)2000—2020年间中国市域“三生”空间功能耦合协调度整体沿胡焕庸线呈现自西向东有序发展的格局,其时空演变具有波动特征。此外,该研究根据2020年中国市域“三生”空间聚集性及协调性特征,提出了两种针对性的分区管控方案并进行对比分析,能够为中国国土空间优化与高质量发展提供参考。
Scientifically identifying the spatial-temporal evolution characteristics of production-living-ecological space(PLES)and their inherent interrelationships is of great significance for achieving optimized spatial layout and sustainable development of national territory.In this study,multi-source spatial-temporal data were integrated to evaluate the heterogeneity and analyze the spatio-temporal evolution of PLES functions in China from 2000 to 2020.The authors identified the spatial clustering and coordination characteristics of PLES at the city level in China and proposed corresponding zoning and regulatory schemes accordingly.The results are as follows.(1)The overall spatial pattern of production space exhibited a trend of"high in the east and low in the west,with significant clustering and minimal dispersal,"and overall expansion outweighed contraction during the study period.Along the Hu Huanyong Line living space generally followed a spatial pattern of"high in the east and low in the west"and remained relatively stable over the study period.Overall,ecological space in China exhibited a spatial pattern of being"higher in the hinterland and lower along the coast,"displaying a trend of expansion throughout the study period.(2)During the period from 2000 to 2020,the spatial functions of PLES at the city level in China exhibited strong clustering characteristics.Among them,the positively correlated clustering areas of production space continued to expand,while the living space remained relatively stable.The positively correlated clustering areas of ecological space showed a pattern of"expansion in the northeast and contraction in the west."Based on this analysis,corresponding zoning and regulatory schemes were proposed in 2020 for different spatial clustering types at the city level in China.Production space was divided into agricultural development zone,urban development zone,potential development zone,and optimization and transformation zone.Living space was categorized into core living zone,potential residential
