基于SBE法的城郊森林公园森林林内景观美学质量评价

SBE Based Evaluation of In-forest Landscape Aesthetic Quality of Forest Park in Suburb

运用心理物理学景观评价原理(Scenic Beauty Estimation,SBE)和多元线性回归方程,对城郊森林公园的森林林内景观的美学质量进行了研究。结果表明:在选取的15个评价指标中,季相与色彩、林木密度、树干形态、林下植被整齐度、郁闭度、林下植被高度、通视性对景观美学质量的影响较大,而树种组成、平均胸径、胸径变异系数、树干排列、林下植被覆盖度、枯落物、枯树倒木、意境美等因素影响较小。据此建立了景观美学质量与各景观因子类目之间的评价与预测的多元回归模型,并提出了相应的优化对策。该评价模型的建立对城郊森林公园森林景观质量管理具有一定的指导意义。

According to the principle of scenic beauty estimation and multi-factor linear regression equation, in-forest landscape aesthetic quality of forest park in suburb of Guangxi was evaluated. Among 15 indices which were selected for the evaluation, 7 indices exhibited significant influences on landscape aesthetic quality, including richness of color, stand density, form of trunks, canopy density, visibility, uniformity of undergrowth, and height of undergrowth. Indices which demonstrated weak influences were the proportion of dominant species,average DBH, coefficient of variation of DBH,arrangement of trunks,coverage of undergrowth,litter,and dead trees＆fallen woods. A multi-factor regression equation for the evaluation was set up based. Countercurrents for the optimlization of the equation were put forward. The model would be helpful to guide the management of landscape quality in the forest park in suburb.
