黄河流域山河交错带三生空间格局变化研究——以河南省新乡市为例

Changes in the“Production-Living-Ecological Space”Pattern in the Interlocking Mountain and River Zones of the Yellow River Basin—Taking Xinxiang City as an Example

本文基于新乡市2010–2020年各类土地利用数据,综合运用动态度、转移矩阵、景观格局指数和地理探测器等方法,探究新乡市“三生”空间的数量结构变化、相互转化、景观格局特征,并对影响特征变化的驱动因子展开分析,揭示“三生”空间变化的规律及当前土地利用过程中存在的问题。研究结果表明:(1)新乡市“三生”空间的变化明显加快,整体表现为生产空间持续减少,生活空间不断增加,生态空间变化较为稳定;(2)在空间转移特征上,生态空间主要向生产空间转化,生产空间主要向生活空间转化;(3)在景观格局特征方面,新乡市景观类型在组分上呈多样化的趋势;(4)新乡市“三生”空间分异受到社会经济因子和自然因子的综合作用。根据实证研究成果,不仅可以为新乡市“三生”空间利用提出相应的优化策略,而且也可以为黄河流域各地级市高质量发展提供重要的科学借鉴。

Based on the land use data of Xinxiang City from 2010 to 2020,this study integrates the methods of dynamic degreetransfer matrix,landscape pattern index and geographical detector to explore the quantitative structural changes,mutual transformations and landscape pattern characteristics of the“production-living-ecological space”(PLES)in Xinxiang City,and also analyzes the driving factors that affect the characteristic changes to reveal the laws governing the changes in the PLES and the current land use process.The results of this study reveal four important aspects of this system.(1)The changes in the PLES in Xinxiang City have accelerated significantly,and the overall performance shows that the production space continues to decrease,the living space keeps increasing,and the ecological space changes are more stable.(2)Regarding the spatial transfer characteristics,the ecological space has mainly transformed to production space,and the production space has mainly transformed to living space.(3)The landscape pattern characteristics show that the landscape types in Xinxiang City are diversified in terms of their components.(4)The spatial differentiation of the PLES is influenced by the combined effect of socio-economic and natural factors.Based on the empirical research results,we can not only propose corresponding optimization strategies for the better utilization of the PLES in Xinxiang City,but also provide important scientific references for the high-quality development of the prefecture-level cities in the Yellow River Basin.
