Land-use conflict (LUC) is a major problem of land management in the context of rapid urbanization. Conflict identification plays an important role in the development and protection of land space. Considering the possibility of, exposure to, and negative impacts of LUC, we explore the probability of land-use cover change (LUCC), policy constraints, and ecosystem service value (ESV) and build a conflict identification model based on the LEC concept of risk assessment. Taking Daye City as an example, we classify the conflict intensity and delimit the key conflict areas. At the same time, a composite classification system is constructed to analyze the spatial characteristics and internal mechanism of conflict. We find that the conflict between construction and ecological space is the main conflict in Daye City (P.R. China), which is widely distributed. However, the conflict between construction and agricultural space, which is mainly distributed near the center of Daye City, cannot be ignored.

Heavy metal pollution in cultivated land poses a serious threat to environmental health and farmers’ livelihoods. As the direct user of cultivated land, understanding farmers’ adaptive behavior to heavy metal pollution, and its influencing factors, can provide insight and information relevant for decision-making, so as to better manage the hazards and risks of heavy metal pollution. We proposed a conceptual framework of “farmers’ characteristics-perceptions-adaptive behaviors”. Factor analysis and mediation effect analysis were used to explore the influence of characteristics and perceptions on adaptive behaviors. The data of 278 farmers in a typical mining area in Daye, China, show that local farmers perceive the hazards of heavy metal pollution, but their adaptive behaviors are hindered to a certain extent. The results of the mediation effect analysis show that perceptions of health impact, self-efficacy, and adaptive cost play a partial mediating role in the impact of characteristics on adaptive behaviors. In addition, the influence of the “factor of dependence on farmland” and the “factor of obstacles to action” on adaptive behavior have no significant relationship with perception levels. By comparing the influencing factors, we found that although farmers’ perceptions have mediating effects between characteristics and adaptive behaviors, characteristics still play a decisive role in adaptive behaviors.
