摘　　要：游憩林是指具有合适开展游憩活动的自然条件和相应人工设施，以满足人们娱乐、健身、休息和观赏等各种游憩需求为目标的一种特种用途林（陈鑫峰等，2003），多指登山道路两边坡度不大、合适开展游憩活动的林分。当前北京市民经济富裕、闲暇时间增多，但生活和工作压力都很大，In-forest landscapes of the middle-aged recreational forests of Pinus tabulaeformis on thick soil of Beijing lower mountainous area were evaluated by SBE method （scenic beauty estimation method） and the multivariate linear models for landscape evaluation and forecast between favor degrees and the factors of in-forest landscape were established using Quantitative Theory I in this paper. The suitable structure and the models of tending techniques of this kind of recreational forests were educed. The study shown that the scenic quality of the recreational forest of P. tabulaeformis should have been enhanced by quantitative tending techniques, including pruning dead branches and alive branches, cutting shrubs, thinning and so on. After tending, the perfect recreational forest of P. tabulaeformis in sunny slope should be with tree density below 1 100 tree·hm^-2, the canopy density about 0.8, the height and coverage of shrub about 1.5 m and 30%, the height of alive branches between 2.5 4.0 m, a small change of vegetation under the canopy, and without deadwood. The perfect recreational forest of P. tabulaeformis in shady slope should be with the tree density about 1 500 tree·hm^-2, the height and coverage of shrub below 1.0 m and 50%, the height of alive branches between 2.5 - 4.0 m, and without deadwood. The results of this paper should expect to offer the theory and techniques support of sustainable management of the middle-aged recreational forests of P. tabulaeformis in Beijing mountainous area, and also for reference to similar area of north of China.
