摘　　要：森林是理想的恢复场所,营建良好的森林环境对公众健康的恢复具有重要意义。以塞罕坝机械林场落叶松林为研究对象,基于40个调查样地,通过设计量表并采用数理统计分析方法,对林内景观进行恢复性评价与美景度评价,探索恢复性效果、美景度与林分结构指标的关系。研究结果表明,落叶松纯林和落桦混交林的恢复性效果无显著性差异(P>0.05),但不同样地间恢复性效果差异较大,恢复性效果的均值和标准差分别为7.126和25.123。恢复性效果与美景度之间呈极显著相关性(P<0.01);恢复性效果和美景度与平均树高、密度呈极显著相关(P<0.01);与郁闭度、下木高度、胸径变异系数呈显著相关(P<0.05)。Forest was an ideal place for restoration,building a good forest environment was of great importance to the restoration of public health.Taking the larch forest in Saihanba Mechanized Forestry Farm as the research object,based on 40 survey plots,through the design of scale and the method of mathematical statistical analysis,the study evaluated the restorative effect and beauty degree of the forest landscape,and explored the relationship between the restorative effect,beauty degree and stand structure index.The results showed that there was no significant difference in the restorative effect between pure larch forest and mixed birch forest(P>0.05),but there were great differences in the restorative effect between different areas.The mean and standard deviation of the restorative effect were 7.126 and 25.123,respectively.There was a significant correlation between restorative effect and beauty(P<0.01).The restorative effect and beauty degree were significantly correlated with average tree height and density(P<0.01).It was significantly correlated with canopy density,lower wood height and DBH variation coefficient(P<0.05).
