Understanding and mastering the temporal and spatial evolution characteristics of land use conflicts is of guiding and warning significance for current regional planning and future prospects.Based on the perspective of"landscape ecology",this paper constructs a spatial model of land use conflict from landscape ecology theory,and quantitatively analyzes the spatial-temporal change characteristics of land use conflict in Zunyi City from 1990 to 2020.The results showed that:(1)From 1990 to 2020,the land use change in Zunyi City showed a trend of"three decreases and three increases",and the land use conflict showed a trend of"decreasing year by year",and the state of basically out of control and serious out of control tended to be basically controllable and stable controllable.(2)The spatial distribution of land use conflicts in Zunyi is"low in the north and high in the south".The high-value areas of land use conflicts are mainly distributed in the urban center and surrounding areas and rural agglomeration areas,while the low-value areas are mainly distributed in mountains and hills and areas with low intensity of human activities.(3)Land use conflicts in Zunyi City have a significant positive correlation and agglomeration trend,showing a distribution pattern of"low in the north and high in the south"at different periods,and the distribution of spatial cold hot spots is characterized by a distribution of"cold spots in the north and hot spots in the south".The results of the study provides a scientific reference for Zunyi City to coordinate the contradictory relationship between economic development and ecological protection and optimize the regional future development model.
