Dynamic Simulation and Evolution of Land Mixed Utilization in Kunming Based on Mixed-Cell-CA Model

The study of land mixed use simulation prediction and evolution law is an important way to improve the vitality of economic development and land use intensity. Based on land use data, this paper uses Mixed-Cell-CA model to predict the land mixed use in Kunming in 2030, and uses information entropy to analyze the relationship between land use evolution and land mixed degree in Kunming. The results showed that the cultivated land and construction land in Kunming changed greatly from 2000 to 2030. In the future, cultivated land is mostly distributed in the eastern region, and new construction land is concentrated near the central urban areas such as Panlong, Wuhua and Guandu. There is a certain correlation between the change of land mixed use and the degree of land mixed. The evolution process of low entropy land mixed use structure is more intense and the degree of structural change is greater. The probability of increasing the proportion of cultivated land is higher in the land with higher mixing degree, and the probability of increasing the proportion of construction land is higher in the land with lower mixing degree. The changes of woodland and grassland have no obvious relationship with land mixing degree.
