Impact of Landscape Pattern on Land Use Efficiency in Guangxi on County Scale
This paper analyzes the overall characteristics and regional differences of land use efficiency and landscape pattern in all districts and counties of Guangxi in 2020 under the research framework of ESDA-GWR, and quantitatively studies the impact mechanism of patch shape characteristics and spatial distribution characteristics of cultivated land, rural residential land, and urban construction land on land use effi-ciency.The results show that land use efficiency of Guangxi is generally on a moderate level yet with significant regional differences, the effi-ciency of center areas within Prefecture level are generally higher relative to the surrounding areas. The Beibu Gulf Economic Zone shows a strong strength on socio-economic development with a high land use efficiency, while the Xijiang Economic Belt develops fast but with a low land use efficiency. Landscape metrics of different areas in Guangxi share a significant positive spatial correlation. The north and southwest part of Guangxi use their land resources in a more intensive way, while central and southeast part is in an extensive developing mode. Regular and contiguous arable land, economical and intensive rural residential land, and"One-Core-Multipart"urban construction land can significantly improve land use efficiency. Among them, the layout of urban construction land that reaches a larger scale and has a clear central urban area has a particularly significant positive impact on land use efficiency.
