Forest ecosystem management research is one of the hot spots and difficulties in forest sustainability development. Because of this, this paper constructs a framework of “integrated forest value assessment-transition point analysis-management strategy decision” from the perspective of integrated forest value assessment and its management strategy decision to maintain the integrity, continuity, and stability of forest ecosystem function. The model is universally applicable, and we obtain the transition periods of most countries in the world based on the model, and quantitatively analyze the forest status of George Jefferson Forest in the United States to obtain the optimal management plan, which verifies the accuracy and reliability of the model.
