Introduction: Against the background of rapid global urbanization, urban space expansion has led to increasingly acute land-use conflicts. Accurately understanding spatial and temporal evolution characteristics conflict patterns measuring level conflicts are crucial for intensifying sustainable use management land resources. Existing research focuses on analyzing current status conflicts, while there is limited discussion tracking spatial-temporal dynamic simulating future trends. Method: In this paper, was measured by constructing a comprehensive index (SCCI) model, spatio-temporal in Harbin-Changchun agglomeration from 2000 2020 discussed. addition, PLUS model used simulate predict pattern 2030, finally put forward control strategy. Results: Result shows that: (1) Over past 20 years, expanded rapidly with two provincial capitals as growth poles. Land-use generally exhibit distribution “high west low east, high core periphery.” (2) During have intensified initially then eased. Severe uncontrolled concentrated transition zone between rural areas agglomerations. (3) Agricultural resource key area contested different interest subjects process development utilization. Discussion: The agricultural priority scenario proves be most effective controlling However, single cannot adequately address multiple rights interests. Therefore, modes should implemented areas. purpose paper provide scientific strategies suggestions agglomerations achieving regional use.
