摘要:
[目的]文章分析“三生”空间的功能时空变化特征,研究其功能间相互作用规律,对国土空间布局优化提供参考。[方法]以黄土高原丘陵沟壑区武山县为研究区,基于格网尺度评价2009年和2015年“三生”功能,运用相关性分析法和双变量局部空间自相关分析法研究“三生”功能间权衡与协同关系类型及时空格局特征。[结果](1)生产空间和生活空间在扩张,其功能值分别提高160%和960%; 生态空间有所缩减,功能值在下降107%。(2)2009年和2015年生产功能与生活功能间存在协同关系,与生态功能为权衡关系;生活功能与生态功能间存在权衡关系。(3)生产功能与生活功能间高—高协同区空间格局在扩大,而低—高权衡区在缩减; 生态功能与生产功能和生活功能之间分别为低—高和高—低集聚的权衡分布,其空间格局较为稳定。[结论]武山县城关镇—洛门镇一体化建设的辐射带动作用明显增强,生态空间受到挤压,结果可为国土空间协调发展提供决策依据。

Abstract:
This research is intends to study the functional evolution characteristics of the production living ecology spaces, analyze the interaction between its functions, so as to provide references for the optimization of the land space layout. Taking Wushan county in the hilly and gully region of the Loess Plateau as the study area, this research used the grid scale to evaluate the production living ecological function in 2009 and 2015, and used the correlation analysis and bivariate local spatial autocorrelation analysis to analyze the types of trade off and synergies and the characteristics of the spatial temporal pattern. The results showed that: (1) The production space and living space were expanding, the functional value was increasing, appearing production function and living function increased by 1.60% and 9.60% respectively. The ecological space was reduced, and the functional value was declining, dropping by 1.07%. (2) In 2009 and 2015, there was a synergistic relationship between production function and living function, the trade off relationship between production function and ecological function, and the trade off relationship between living function and ecological function. (3) In space, the spatial pattern of high high synergy between production function and living function was expanding, while the low high trade off area was shrinking. The trade off distribution between ecological function and production function and living function was low high and high low agglomeration, and its spatial pattern was relatively stable. It concludes that the radiation belts of the integrated construction of Chengguan town Luomen town in Wushan county are obviously enhanced, which makes the ecological space affected. This study could provide a decision making basis for the coordinated development of production living ecological space.
Key words:  land use  production living ecological function  trade offs and synergies  bivariate spatial autocorrelation  Wushan county
