摘　　要：游憩林是一种能为公众提供舒适游憩环境的重要特种用途林,科学经营该森林对于改善人民群众的身心健康及促进森林游憩业的发展意义重大。侧柏游憩林在北京地区分布广泛,且长期以来深受市民的喜爱。为探明其优化抚育模式及间隔期,分别对北京西山国家森林公园内阴、阳坡中龄林进行3种不同模式的抚育,定位监测抚育前后5年间林分风景质量及主要风景要素的变化情况,基于美景度评判法(SBE法)探讨不同抚育模式对林分风景质量的效果及持续时间。结果表明:1)不同抚育模式均可在短期内大幅提高阴、阳坡2种林分的喜好度,明显改善林分的风景质量;2)阴坡林分3种抚育模式(A1,A2和A3)对风景质量的作用效果均较为理想,阳坡林分3种抚育模式(B1,B2,B3)中的B1较B2和B3效果更好;3)综合考虑抚育的效应及持续时间,认为阴坡林分更适合采用A3模式(修枝高度2～3m+割灌保留盖度约20%+林地清理),抚育间隔期为2年;阳坡林分更适合采用B1模式(修枝高度2～3m+割灌保留盖度约25%+林地清理),抚育间隔期至少为4年。从森林美学角度提出的优化抚育模式及间隔期,可为北京山区侧柏游憩林的抚育决策提供直接的技术支撑。The recreational forest is an important type of special - purpose forests in China, which can provide general public with comfortable recreational environments. Scientific management of the forest is vital important to peoples＇ physical and mental health and also to development of forest tourism industry. The Platycladus orientalis recreational forests, which are widely distributed in Beijing, have long been well received by local residents. To determine optimal tending regime and interval for the forest, three different tending regimes were applied to middle - aged stands on shady and sunny slope in the Xishan National Forest Park of Beijing. The dynamics of scenic quality and major scenic factors of both stands were monitored for five successive years before and after tending. Based on Scenic Beauty Estimation Method, effect of these applied tending regimes on scenic quality and its duration were analyzed. The results showed that： 1 ） Different tending regimes greatly increased preference degree of two stands in short terms, and significantly improved their scenic quality. 2） Three tending regimes （A1, A2 and A3） for shady slope stand had similar excellent scenic effect, while for sunny slope stand the B1 regime had better effect than the other two （B2 and B3）. 3） When the scenic effect and its duration were both taken into consideration, A3 regime （ clear bole height of 2 - 3 m above ground, remained cover of shrub layer about 20% plus ground clearing） was better for shady slope stand, and corresponding tending interval could be 2 years; while for the sunny slope stand, B1 regime （clear bole height of 2 -3 m above ground, remained cover of shrub layer about 25% plus ground clearing） was more appropriate and its tending interval Could be at least 4 years. From the perspective of forest aesthetics, tending regimes and corresponding intervals proposed in this study would providetechnical support for tending practice of the P. orientalis recreational forest in Beijing mountainous areas.
