Abstract：In a multifunctional land use evaluation index system established based on the ecologicallivingproductive space, an improved entropy weight TOPSIS method was used to evaluate the multifunctions of land use in the new firsttier city of Nanjing, and its timevarying characteristics, tradeoff synergy and barriers, and so on. The results showed that: the multifunctions of land use in Nanjing showed an inverted Ushaped trend during the study period, in which the productive and living functions were increased and the ecological functions were declining, there were different degrees of synergy and tradeoff between the productive, living and ecological functions of the land in Nanjing, and the barriers between the productive and ecological functions of the land continued to increase, among which the annual average concentration of SO2 and forest coverage had a significant effect, and the degree of disturbance of living function decreased continuously. Therefore, the new firsttier cities should strengthen the ecological spatial service function of land and reduce the negative ecological effects brought by living and productive activities in the balance of the synergistic relationship between land living, productive and ecological functions, and guide the evolution of land functions to a highly coordinated direction.
