The evolution process of the forestry ecological security in China mainly shows the characteristics of a slightly better volatility and striking regional difference. At present, the insufficient momentum in the improvement of the forestry ecological security and its unbalanced development among regions still restricts the realization of the overall forestry ecological security in China. If the government does not take active measures, the forestry ecological security in China will not be effectively guaranteed in the future. In order to achieve the goal of "beautiful China" as soon as possible, ensure the harmonious co-integration of the forestry ecosystem and economic development, relevant policies need to be further improved, and long-term maintenance mechanisms need to be established. Therefore, this paper puts forward the "three vehicle theory of forestry ecological security"——guard the bottom line by drawing the redline of forestry ecological security; create a driving force by evaluating the implementation effect of forestry policies to improve the forestry policy system; establish a mechanism to improve the supporting system of forestry ecological security evaluation.%纵观我国林业生态安全的演进过程,主要呈现出波动性弱改善、区域性差异明显等特征.目前,林业生态安全改善势头不足,区域林业生态安全状况发展不均衡等依然制约着我国整体林业生态安全的实现.若任由这一趋势发展,未来我国林业生态安全状况将无法得到有效保障.为尽快实现"美丽中国"建设目标,确保林业生态系统与经济发展的和谐共融,需进一步完善相关政策,设立长效维护机制.由此,本文针对我国林业生态安全的长期维护机制提出"林业生态安全三车论",包括:守底线,划定林业生态安全保护红线;设驱动,评价林业政策实施效果健全林业政策体系;建机制,完善林业生态安全评估配套保障体系等三驾马车.
