To reveal the coupling and coordination effect between land intensive utilization and the ecosystem, alleviate land supply - demand pressure, and curb ecological degradation from extensive land use, the East China region, as the core for high - quality development, is crucial for land intensive utilization and ecological protection. This paper constructs a coupling coordination degree model for interdisciplinary research to analyze the interaction between land resource utilization efficiency and ecosystem health. Research shows that the coupling coordination degree of land intensive utilization and ecological environment protection in East China provinces and cities has been improving. Jiangsu and Shandong are in coupled and coordinated development; Zhejiang, Anhui, Fujian, and Jiangxi are approaching imbalance and decline; Shanghai is in mild imbalance and decline. The ranking of the comprehensive index of the land intensive utilization subsystem is: Jiangsu > Shandong > Zhejiang > Anhui > Fujian > Jiangxi > Shanghai. The ecological environment system subsystems fluctuate with significant provincial differences. Therefore, East China provinces and cities should adhere to the "three zones and three lines" policy, optimize spatial layout, upgrade industrial structure, strengthen ecosystem protection, and enhance ecological service functions.
