土地利用隐性形态与生态环境耦合协调发展及其影响因素研究——以广西为例

Research on the coupling coordinative degree of recessive land use morphology and ecological environment and its influencing factors:A case study of Guangxi

经济社会发展过程中,不但要推动土地利用转型的优势发展,还要改善土地利用结构、维护生态环境。本文运用综合指数法、耦合协调度模型以及地理探测器等方法对广西2005—2019年土地利用隐性形态与生态环境耦合协调关系及其影响因子进行研究,得出以下结论。(1)土地利用隐性形态水平空间格局为桂东南高,桂西北低。生态环境综合水平呈现桂东地区和中部重点城市高,桂南沿海地区与中部地区低的特征。(2)耦合协调发展值呈协同上升趋势,城市间的耦合协调发展存在差异,空间上呈“东部、中部高,西部低”的特征。(3)二者的耦合协调受到经济、社会、生态资源因素的共同作用,其中,土地产出效益的影响最为显著。未来要推动土地利用优势转型,维护生态环境,加快绿色产业升级,促进土地利用隐性形态与生态环境协调发展。

In the process of social and economic development,it is not only necessary to promote the transformation of land use superiority,but also to improve the structure of land use and ecological environment.This paper studies the coupling and coordination relationship between recessive land use morphology and eco-environment in Guangxi from 2005 to 2019 as well as its influencing factors by means of composite index,coupling coordinative degree model and geo-detector.The findings are as follows:(1)The spatial pattern of recessive land use morphology was high in southeast Guangxi and low in northwest Guangxi.The comprehensive level of ecological environment was high in the eastern region of Guangxi and the key cities in central Guangxi,but low in the southern coastal areas and the central areas in Guangxi.(2)The value of coupling and coordinated development showed a synergistic upward trend,and there were differences among cities,with a spatial feature of“high in the east,middle and low in the west”.(3)The coupling and coordination were affected by economic,social and ecological resources,among which the effect of land output was the most significant.In the future,it is necessary to promote the transformation of land use superiority,safeguard ecological environment,speed up the upgrading of green industry,and promote coordinated development of the recessive land use morphology and ecological environment.
