为促进江西省国土空间功能结构优化,以江西省为研究区域,从不同时空、不同尺度上对江西省“三生”空间功能格局进行分析,揭示2006—2015年江西省“三生”空间功能类型的时空分布规律和特征; 应用景观生态学方法中的计量模型计算出空间格局指数,再结合ArcGIS 10.2软件的空间聚类分析研究了其空间分布特征。结果 表明:江西省“三生”空间功能结构分布格局呈现出比例结构不协调现象。从县域到市域进行多尺度跨时空分析,可以看到研究区多样化分布格局呈现北部偏高,南侧偏低的递减格局,集中化指数空间分异较显著,整体优势度较高,且呈现南北两侧高、中间偏低的空间格局特征; 空间功能结构均匀度水平较低的特征。

In order to promote the optimization of the spatial function structure of Jiangxi Province, taking Jiangxi Province as the research area, we analyzed the spatial function pattern of ‘ecology-production-living' space in Jiangxi Province from different time, space and scale, and revealed the spatial and temporal distribution rules and characteristics of the spatial function types of ‘ecology-production-living' space in Jiangxi Province from 2006 to 2015. The spatial pattern index was calculated by using the econometric model in the landscape ecology method, and then the spatial distribution characteristics were studied in combination with the spatial clustering analysis of ArcGIS 10.2 software. The results show that the distribution pattern of the spatial function structure of ‘ecology-production-living' space in Jiangxi Province presented the disproportionate proportion structure. Multi-scale cross-spatial-temporal analysis from county to city shows that the diversified distribution pattern of the study area presents the decreasing pattern from the north to the south. the spatial differentiation of concentration index is more significant, and the overall dominance is higher, showing the spatial pattern features with high levels in the south and north and the low level in the middle, and the features of low level of uniformity of spatial functional structure.
