［Objective］ The impact of land use change on the evolution of ecological profit and loss under multi-scenario simulation in Chaoyang was explored to provide a reference for the land space planning and ecological environment protection of the agro-pastoral ecotone in Northeast China. ［Methods］ Based on the land use data of Chaoyang in 2000, 2010 and 2020, the Markov-PLUS model and ecological footprint model were used to analyze and predict the evolution characteristics of land use structure and ecological profit and loss of Chaoyang under four scenarios from 2000 to 2030. On this basis, the response of ecological profit and loss to land use change were explored by using the ecological elasticity model. ［Results］ 1) The land use change in Chaoyang from 2000 to 2020 was quite drastic. Cultivated land and grassland were the main types of land use, accounting for more than 80% of the total land area. 2) From 2000 to 2020, Chaoyang showed a change from ecological deficit to ecological surplus, with an overall incre
