中文摘要：

在采用SBE法对新疆喀纳斯旅游区森林景观美学质量评价的基础上，研究其森林景观美学质量与自然火干扰之间的关系。结果表明：1）喀纳斯旅游区的森林景观美学质量整体较高，阔叶针叶树种比值大、树种丰富、林相简单整齐的森林景观受人青睐；2）喀纳斯旅游区森林景观美学质量与森林发生自然火干扰时间的早晚有关，自然火干扰发生时间越早，森林景观目前表现的美学质量越低，反之亦然。自然火干扰通过对森林群落树种结构形成的作用，进而深刻影响森林景观美学质量的具体表现，是新疆喀纳斯旅游区森林景观美学质量形成的重要源动力之一。结论为喀纳斯以森林景观美学质量为价值取向的森林景观资源的可持续经营提供科学依据。

英文摘要：

This paper evaluated the aesthetic quality of forest scenery in Kanas tourism district by using scenic beauty estimation method（SBE） ,and studied its relationship with natural fire disturbance. The results indicated： 1 ） The scenic beauty value of forest scenery was universally high, and people preferred the forest scenery with rich tree species and orderly storey. 2）There was a close relationship between forest scenery aesthetic quality and the time occurring natural fire disturbance. The earlier natural fire disturbance occurred the lower aesthetic value forest scenery was, vice versa. Fire disturbance was one of the main factors which influenced the forest scenery aesthetic quality by controlling formation of tree structure. This knowledge would provide reliable theoretic guidance and feasible scientific approaches for sustainable management of forest landscape and protection of biological diversity in terms of scenery aesthetic quality.
