In order to provide reference for the overall planning of land space control and the rational use of natural resources,taking Nanchang City as an example,we first identified the types and intensity differences of ‘three line conflict' through the intensity index of ‘three line conflict',studied the spatial characteristics of ‘three line conflict' by using the spatial autocorrelation analysis method,and established regression model through bivariate correlation analysis and multiple linear regression analysis to explore the influencing factors of ‘three line conflict',which is helpful to deepen the understanding of ‘multi-dimensional conflict' and provide reference for the realization of land space optimization. The results show that:(1)the conflict areas of ‘town-basic farmland',‘town-ecology',‘ecology-basic farmland' and ‘town-ecology-basic farmland' in Nanchang are 7.391 km2,5.842 km2,149.939 km2 and 0.111 km2,respectively,the intensity indexes are 0.001,0.000 8,0.021 and 0.000 02,respectively;(2)‘town-basic farmland',‘town-ecology' and ‘ecology-basic farmland' conflicts have obvious spatial aggregation; most of the hot spots of the conflict are located in the north central Anyi County,the middle Jinxian County,the North Nanchang County and the north central Xinjian County,and most of the cold spots are located in Wanli District and the East Jinxian County;(3)slope,residential density,population,urbanization rate,distance from the city center and distance from the main roads all have some influences on the intensity indexes of various conflicts. The results can be used as reference for the future coordination and optimization of the ‘three line' layout and scientific and reasonable allocation of land resources.
