摘要: 揭示江苏省县域“三生”功能的时空关联特征及协同/权衡关系,可为县域空间规划布局提供理论支持。从生产—生活—生态三个维度构建国土空间三生功能识别体系,以空间自相关和相关系数法定量测算江苏省55个县域1996年、2005年、2015年三个时期的“三生”功能时间效应及协同/权衡关系。结果表明:(1)江苏省“三生”功能生态位宽度变化各异,空间分布各具特色,具体表现为:1996-2015年生产功能生态位宽度时序上总体呈增长状态,变化过程具阶段性;空间上呈“南高北低”格局特征,长江南岸条带状集中分布,长江北岸则呈多集聚斑块状。1996-2015年生活功能生态位宽度不断压缩,空间上具以市辖区为中心向外同心圆衰减规律。1996-2015年生态功能生态位宽度不断增大,空间上生态功能生态位宽度具依山傍水呈高值特征。(2)江苏省1996-2015年间,生产功能、生活功能、生态功能均有随时间变化正相关类型(高高、低低)集聚明显,“组团”式分布;负相关类型(高低、低高)集聚性低,“离散”状分布规律。 (3)生产与生活功能存在空间协同关系,生产与生态功能呈协同/权衡波动变化态势,生活功能与生态功能变化趋势类似于生产与生态功能,交叉变化更明显,不同年份协同/权衡关系在不同单元有明显差异。研究表明,以上特征均与区域经济社会发展有较强的吻合性,未来应逐步改变以生产功能过速扩张压缩生活、生态功能的现象,应以保护生态环境、提升生活质量实现“三生”更加协同。

Abstract: This paper reveals the spatial-temporal correlation characteristics and coordination/trade-off relationship of the "production-living-ecological" functions in the county of Jiangsu province, which can provide theoretical support for the spatial planning of the county. Based on the theory of "production-living-ecological" spatial superior group and niche situation theory, this paper constructs the function recognition system of land space from three dimensions of production, life and ecology. The spatial autocorrelation and correlation coefficient method were used to quantitatively measure the time effect and coordination/trade-off relationship of the "production-living-ecological" function in Jiangsu province in 1996, 2005 and 2015. The results were obtained as follows: (1) The niche width of "production-living-ecological" functions in Jiangsu was varied, and its spatial distribution had its own characteristics. The specific manifestation was that the niche width of production function had a general increasing trend in the period 1996-2015, but the changing process had the stage characteristic, presenting a pattern of "high in the south high but low in the north", the south bank of the Yangtze River was in strips distribution, and the north bank was multi-aggregated. From 1996 to 2015, the niche breadth of life function was continuously compressed, and the space was attenuated by the concentric circle centered on the municipal area. In the same period, the ecological function niche width increased continuously, the ecological functional niche breadth in space has high value near the mountain and water. (2) From 1996 to 2015, the three functions of production, life and ecology in this province had positive correlation type (HH, LL) clustering obviously, presenting a "group" type distribution with the change of time. On the contrary, negative correlation type (HL, LH) with low agglomeration, showing a "discrete" distribution. (3) Production and life function had spatial synergistic relationship, and production and ecological functions showed a coordination/trade-off fluctuations. The changing trend of life function and ecological function was similar to the production and ecological function with more obvious change, and the coordination/trade-off relationship in different years had obvious differences in different units. Studies have shown that all of the above characteristics were in good agreement with regional economic and social development. In the future, we should gradually change the phenomenon of production function expansion and compression of life and ecological functions, so as to protect the ecological environment and to improve the quality of life oriented coordinated and optimized development path.
