摘要:
[目的] 探究广西壮族自治区国土空间“三生”功能之间的协调关系,为区域的协调发展调控提供科学依据。[方法] 采用多因素综合评价法评价2009-2018年广西“三生”功能利用程度,并应用耦合协调模型,分析三者之间的变化特征及耦合协调关系。[结果] ①2009-2018年广西“三生”功能得分整体呈上升趋势,其中生活功能变化最大且各地级市上升幅度不尽相同。②广西国土空间“三生”功能耦合性指数缓慢增长,协调发展度分值分布不均,各地级市协调等级上升跨度不同。③广西国土空间“三生”功能耦合协调性空间分布呈西部地区大于东部地区,沿海地区大于内陆地区。[结论] 广西国土空间“三生”功能均有较大提升,各地级市发展速度不尽相同;空间分异呈“东北、西南高,西北、东南低”的特征,生产功能和生活功能存在一定联系;广西国土空间“三生”功能良性互动越来越强,空间分异明显呈西部向东部地区逐渐升高特征,各地级市之间发展不均衡现象显著。

Abstract:
[Objective] The coordinated relation between the productive-living-ecological functions of Guangxi Zhuang Autonomous Region land space was explored to provide a scientific basis for the coordinated development and regulation of the region.[Methods] The multifactor comprehensive evaluation method was used to evaluate the utilization degree of the productive-living-ecological function from 2009 to 2018, and the coupling coordination model was applied to analyze the change characteristics and coupling coordination relation among the three founction.[Results] ① From 2009 to 2018, the score of the production-living-ecological function showed an upward trend, among which the life function changed the most and the rising range of each prefecture level city was not the same. ② The coupling index of the production-living-ecological function of Guangxi's land space was growing slowly, the distribution of the coordinated development degree was uneven, and the rising span of coordination levels of different cities was different. ③ The spatial distribution of productive-living-ecological function coupling coordination in the western region was larger than that in the eastern region, and that in the coastal area was greater than that in the inland area.[Conclusion] The productive-living-ecological function of Guangxi's land space has been greatly improved, and the development speed in each city is different. The spatial differentiation shows the characteristics of being high in the northeast and southwest, and low in the northwest and southeast, and there is a certain relation between the production and life functions. The positive interaction of the productive-living-ecological function of Guangxi's land space is becoming increasingly strong, and the spatial differentiation is evident from the west to the east with the characteristics of a gradual increase. The imbalance of development among cities is significant.
