Abstract: In response to the problems in the development of Liaoning urban agglomeration， the allometric growth model and urban economic development model were constructed from urban population， land urbanization， gross national product， social fixed investment， etc.， and a long-term study on the human-land relationship of Liaoning urban agglomeration was carried out by using DMSP， VIIRS night light data and urban economic data. The human-land urbanization and economic development level of prefecture-level cities were measured， and the targeted evaluations were made. The results showed that the human-land relationship of Liaoning urban agglomeration is mainly affected by the development of heavy industry economy and resource-based cities. Among them， the development of Shenyang City tends to be flat， while the development of such cities as Huludao and Dandong tends to be three-dimensional. For cities with better economic development， the extensive expansion of urban construction land should be prevented， and for cities with lagging economic development， the employment opportunities should be created to attract population gathering. The research results have certain reference value for the future urbanization development of Liaoning urban agglomeration.
