Abstract
As China rapidly urbanizes, land resources tend to deplete. This paper aims to identify and propose a resolution of land use conflicts to promote sustainable land use and coordinate the interaction between humans and the environment in urban areas. The methodology of land use conflict assessment within spatial zoning of the Su–Xi–Chang region was evaluated. Taking into consideration the intensity of human activities and the background condition of the natural environment, we divided the study area into a few regions. Furthermore, we developed a methodology by calculating landscape complexity, fragility, and stability based on spatial zoning so as to derive the spatio-temporal characteristics of the land use conflict index (LUCI) in the Su–Xi–Chang region. The results indicate the following: (1) According to the urban spatial attribute index (USAI) statistics, we delineate the core, fringe, and suburban zones of the Su–Xi–Chang region, which accounted for 9.61%, 11.06%, and 79.33% of urban agglomerations respectively; (2) from 1990 to 2018, the fragility index (FI) and LUCI showed S-shaped curves, while the complexity (CI) and the stability indices (SI) exhibited minor fluctuations in the fringe and suburb zones; and (3) intensive and severe conflict is concentrated in core areas due to quite intense human activities and in fringe areas due to an increased interaction between humans and land, while moderate conflict is mainly found in rural and suburban areas that pose as a natural environmental space. The results can serve as a theoretical framework for an effective identification of the LUCI in an urban agglomeration and coordination of the optimal allocation of regional land resources.

Within the context of rapid urbanization and industrialization, land use conflicts pose a serious challenge to the sustainability of the land system and regional coordinated development
Step 1: Gradually introduce the nighttime lightlight (NTL), gross primary productivity (GPP), Road maps, and land surface temperature (LST) data to establish an optimal model for spatial zoning of the Su–Xi–Chang region
While including multivariate logistic regression, this study gradually introduces the NTL, GPP, Road maps, and LST data to establish an optimal model for spatial zoning of the Su–Xi–Chang region
Summary
Within the context of rapid urbanization and industrialization, land use conflicts pose a serious challenge to the sustainability of the land system and regional coordinated development. Since attention is constantly directed towards the construction of an ecological civilization, studies on land use conflict have gradually become a hot topic for scholars [1,2]. In reference to studies on social, resource, eco-environmental, and spatial conflicts [3], land use conflicts are believed to occur when different land use stakeholders pursue incompatible interests or when various land use methods and the environment are contradicting [4]. Due to the development of global urbanization, the identification of land use conflicts has become an important decision-making problem for the urban environment [5,6]. It is useful to develop a feasible model to map land use conflict patterns in urban areas and determine conflict levels within a spatial division of urban agglomerations
