Abstract

With the rapid development of urban-rural integration and socioeconomic, the utilization of rural settlements (RS) and sloping cultivated land (SCL) in the karst mountain areas (KMA) of Southwest China is gradually changing. Clarifying the evolving relationship between RS and SCL is crucial for coordinating human-land relations and promoting rural development. Therefore, this study attempts to reveal the spatial coupling relationship between the two and analyze the transformation of the human-land relationship reflected by these changes. Firstly, this study constructs a theoretical framework for the coupled evolution of RS and SCL in the KMA of Southwest China and the change in human-land relations reflected by the two. Then, based on typical cases, we conduct empirical analysis. The findings of this study are as follows: (1) The dynamics of RS and SCL have changed significantly, with the area of RS showing an increasing trend over time, while that of SCL initially increased and then decreased. (2) RS are predominantly distributed in middle elevation zones, whereas SCL is mainly distributed in middle and high elevation zones, both concentrated in areas with steeper slopes. (3) The distribution structure of coupled types of RS and SCL is different and is influenced by socioeconomic, natural environment, and policy factors. (4) Under different geomorphic units, the coupling relationship between RS and SCL is diverse, reflecting variations in human-land relations. This study provides a theoretical basis for regulating the human-land relationship and offers empirical cases for addressing the challenges of sustainable rural development in the KMA.

西南喀斯特山区乡村聚落与坡耕地利用耦合协同路径的空间多样性——以花江峡谷为例

随着城乡一体化和社会经济的快速发展，西南喀斯特山区农村居民点和坡耕地的利用方式正在逐步发生变化。厘清农村土地与农村土地关系的演变关系，对于协调人地关系、促进农村发展具有重要意义。因此，本研究试图揭示两者之间的空间耦合关系，并分析这些变化所反映的人地关系的转变。首先，本文构建了西南KMA中RS和SCL耦合演化的理论框架，以及两者所反映的人地关系变化。然后，根据典型案例进行实证分析。研究结果表明：(1)RS和SCL的动态变化明显，RS面积随时间呈增加趋势，而SCL面积先增加后减少。(2) RS主要分布在中高程，SCL主要分布在中高程，均集中在坡度较陡的地区。(3) RS和SCL耦合类型的分布结构存在差异，并受社会经济、自然环境和政策因素的影响。(4)在不同地貌单元下，RS与SCL的耦合关系是多样的，反映了人地关系的变化。该研究为调整人地关系提供了理论依据，并为应对KMA农村可持续发展的挑战提供了实证案例。

期刊介绍： The journal Ecological Informatics is devoted to the publication of high quality, peer-reviewed articles on all aspects of computational ecology, data science and biogeography. The scope of the journal takes into account the data-intensive nature of ecology, the growing capacity of information technology to access, harness and leverage complex data as well as the critical need for informing sustainable management in view of global environmental and climate change. The nature of the journal is interdisciplinary at the crossover between ecology and informatics. It focuses on novel concepts and techniques for image- and genome-based monitoring and interpretation, sensor- and multimedia-based data acquisition, internet-based data archiving and sharing, data assimilation, modelling and prediction of ecological data.
