- Abstract:
- [Objective]This study aims to explore the formation process of the spatial pattern of rural settlements in the Xiangjiang River Basin under the influence of multiple factors, to provide theoretical support for optimizing rural land resource allocation, and to offer scientific guidance for village planning and construction. [Methods]Landscape pattern indices, kernel density analysis, spatial autocorrelation analysis, and spatiotemporal geographically weighted regression models were used to investigate the spatiotemporal evolution characteristics and influencing factors of rural settlements in the Xiangjiang River Basin from 2000 to 2020. [Results](1)Rural settlements in the Xiangjiang River Basin were primarily concentrated in the Changsha-Zhuzhou-Xiangtan and Hengyang-Yongzhou-Chenzhou areas, with fewer distributions in other regions, mainly exhibiting a ‘dense level in plains, sparse level in mountains' characteristic.(2)The growth of land used for rural settlements in the Xiangjiang River Basin was significant, with a slowdown in fragmentation, an improvement in shape regularity, and a noticeable trend of clustering.(3)The number and area of rural settlements showed similar spatial clustering characteristics, with the spatial distribution of high-high and low-low clustering types remaining relatively stable. However, the low-low clustering type was gradually decreasing. The average shape index showed an expanding range of high-low clustering and a significant strengthening of clustering characteristics, while the low-low clustering feature weakens.(4)The impact of various factors on rural settlements in different regions was becoming less pronounced, with the area of crop cultivation remaining the dominant driver of the distribution of rural settlements. [Conclusion]Under the influence of multiple factors, the land layout and structural form of rural settlements in the Xiangjiang River Basin were continuously optimized, and the human living environment had significantly improved. It is recommended to focus on the development of non-agricultural economy while paying attention to agricultural development and rural construction.
