Characterizing land use transition in China by accounting for the conflicts underlying land use structure and function

Abstract

Human activities and global changes have undergone significant transformations in land systems. It is imperative to comprehend the intricacies of land use transitions (LUT), as they serve as indicators of the evolving dynamics within the complex human-environmental relationship. In this study, we adopt the conflict-coordination theoretical framework to delve into the role of land-use conflicts (LUC) in driving LUT. Our investigation involves the quantification of LUT and the assessment of LUC within China, spanning from 1980 to 2020. Subsequently, we scrutinized the interplay between LUT and LUC using Spearman correlation analysis and the Wilcoxon test. Our findings reveal that greater diversity in land-use structure can be attributed to ecological land fragmentation and the restoration of unused land, while the expansion of urban and cropland areas contributes to a less diverse land-use pattern. Furthermore, there is a discernible upward trend in land use function. Although the overall degree of LUC in China is relatively mild, there is a noticeable upward trajectory over the past four decades. More pronounced conflicts within land-use patterns promote a diversified land-use pattern, while conflicts arising from competing land-use functions elevate the level of land-use functionality. Moreover, a dynamic interplay between land-use transitions and conflicts becomes evident, with intense conflicts within land-use patterns weakening land-use functionality, and imbalances in functionality driving greater diversity in land-use patterns. Our research introduces an innovative analytical framework that elucidates LUT through the lens of LUC, with the potential for broader applicability across different regions. This framework not only enhances our understanding of LUT but also provides valuable scientific guidance for the effective management of conflicts to promote the sustainable development of land resources.
