摘  要：
为研究北京山区低山厚土中龄侧柏游憩林的合理构成,采用SBE法对侧柏游憩林林内景观进行景观评价,应用数量化理论Ⅰ建立喜好度与各景观类目之间的景观评价和预测模型,并由此分析得出定量化的抚育技术模式。研究表明,应当通过定量化的清枯枝、修活枝、割灌和间伐等抚育措施提高游憩林的景观质量,将阳坡侧柏游憩林抚育成无枯枝、密度在1 750株/hm2左右、郁闭度在0.8左右、灌木层高度和盖度分别在1.0 m和50%以下、第一活枝高在4.0 m左右、林下层有一定变化的高景观质量林分;将阴坡侧柏游憩林抚育成无枯枝、密度在1 000株/hm2以内、郁闭度在0.8左右、灌木高度不超过0.5 m、盖度在30~50%之间、第一活枝高在4.0 m左右、林下层较统一的高景观质量林分。

摘  要：
In order to study the suitable composition of the middle-aged recreational forest of Platycladus orientalis on thick soil of Beijing low mountainous area,its in-forest landscapes are evaluated by scenic beauty estimation(SBE) method in this paper.The multivariate linear models for estimation and forecast on landscape quality between favor degree and the structural factors of in-forest landscape are established using Quantitative Theory Ⅰ,then the models of tending techniques are educed.The study shows that the scenic quality of the P.orientalis recreational forest should be improved by quantitative tending techniques,such as pruning dead branches and lower alive branches,cutting shrubs,thinning and so on.After being tended,the perfect P.orientalis recreational forest on sunny slope should be such woodlands with the forest density about 1 750 stems/hm~2,the canopy density about 0.8,the height and coverage of shrub below 1.0 m and 50% respectively,the height of alive branches about 4.0 m,vegetaion change under the canopy to a certain extent and without deadwood.The perfect P.orientalis recreation forest on shady slope should be such woodlands with the forest density below 1 000 stems/hm~2,the canopy density about 0.8,the height and coverage of shrub below 0.5 m and 30%～50% respectively,the height of alive branches about 4.0 m,a less change of vegetation under the canopy and without deadwood.
