植物群落特征和林分空间结构组成及评价是森林公园景观的关键,对森林公园景观优化与提升具有重要意义。以福建金丝湾省级森林公园为对象,基于40个调查样方,从群落特征和林分空间结构2个层面选择24个景观影响因子,运用美景度评价法(SBE)得出各个样方景观得分值,进而构建美景度和各个影响因子类目之间的景观评价与预测的多元回归线性模型,并分析群落特征和林分空间结构对森林公园景观美学质量的贡献作用。结果表明:森林公园景观中,主要影响美景度的景观因子有凋落物、林下层统一度、乔木丰富度、郁闭度、胸径变异系数、竞争指数、枝下高和角尺度,其贡献率分别为20.809%,20.424%,14.547%,14.162%,10.790%,8.189%,6.455%和4.624%;群落特征和林分空间结构2个层面的贡献率分别为87.187%和12.813%。植物群落特征和林分空间结构相互作用在森林公园美景度评价中占据着重要地位。
The characteristics of plant community and the spatial structure of the forest stand are the key to the landscape of the forest park, which is of great importance to the landscape optimization and improvement of the forest park. Taking Fujian Jinsiwan Provincial Forest Park as an example, based on 40 surveyed quadrats, 24 landscape influence factors were selected from two aspects of community characteristics and spatial structure of the forest. By using the landscape evaluation method (SBE), the quadrats And then construct the multiple linear regression model of landscaping and landscape evaluation and prediction among the various categories of influencing factors and analyze the contribution of community features and spatial structure of the forest to the landscape aesthetic quality of the forest park. The results showed that the main landscape factors of landscape in the forest park were litter, understory uniformity, arbor richness, canopy density, coefficient of variation of breast diameter, competition index, branch height and angle scale, respectively Were 20.809%, 20.424%, 14.547%, 14.162%, 10.790%, 8.189%, 6.455% and 4.624%, respectively. The contribution rates of community characteristics and spatial structure of the forest were 87.187% and 12.813% respectively. Plant community characteristics and spatial structure of forest interactions play an important role in the evaluation of the beauty of forest parks.
