Abstract:

The scarcity of land resources and multi-functional use of land are the root causes of land use conflict. Land use conflict is known to aggravate the relationships among economic interests, ecological benefits, and social benefits. The study of land use conflict is of great significance in efforts to achieve the concepts of “multi-rule integration” and “three spaces and three lines” in China land space planning. Unfortunately, research related to this conflict presents relatively scattered characteristics. This paper summarizes the findings of studies on land use conflict published at home and abroad in recent years and describes the concepts and types of land use conflict. The characteristics of different types of land use conflict are analyzed, and the urban-rural interlaced zone is identified as a research hotspot. The significance of studies on spatiotemporal dynamics is emphasized, and the fact that stakeholders tend to pay more attention to the dynamic evolution of conflict occurrence and development instead of the results of such conflict is highlighted. Thereafter, the main drivers of land use conflict, including natural factors, such as the limited area and suitability of land, as well as human factors derived from different human needs for production, life, and the ecological environment, are derived. This paper also presents the coordination and trade-offs of conflict under different driving factors and proposes that exploring the trade-offs and synergy between different land functions, including multiple functions, may be helpful for conflict coordination. The results of land use conflict research can be applied to planning and environmental management. The scientific and reasonable application of conflict research results is a valuable direction in land use conflict research. The suitability of participatory survey, game theory, pressure-state-response (PSR) mode and its extended models, multi-objective evaluation, and landscape ecological risk assessment in the study of land use conflict is further analyzed and evaluated. As a qualitative method, participatory surveys can provide an accurate and in-depth understanding of land use conflict, but they are highly subjective and limited to small study areas. Game theory can also be used to explore the internal mechanism of land use conflict extensively, but it assumes that the stakeholders are rational. PSR mode and its extended models and multi-objective evaluation could be used to quantify land use conflict by selecting appropriate indicators, but they are prone to subjectivity. Landscape ecological risk assessment is objective but does not take into account socioeconomic factors. Future research could seek to improve the theoretical basis of land use conflict, expand the available research methods, assess the contribution of conflict dynamics, and create effective land space planning strategies. This paper systematically describes the current research progress on land use conflict and offers a comprehensive reference to guide future developments in conflict research.
