为提高枯木资源在景观营造中的观赏及文化效益,以云南省大理洱海枯木景观作为评价对象,收集26张具有典型代表性的枯木景观照片,采用美景度评判法(scenic beauty estimation method,简称SBE法)和多元线性回归进行综合分析。结果表明,枯木布置位置的贡献率最大,达41.30%;其次为枯木生命状态、水生植物、原枯木种植形式,贡献率在10.00%以上;枯木树形艺术性、枯木状态、植物层次等要素对其影响较小,贡献率分别为6.33%、5.52%、5.42%。在分析各景观要素贡献率和美景度模型中方程构建的基础上,提出了洱海枯木构建的技术要点,包括枯木布置位置、枯木种植形式、枯木艺术形态以及植物配置等枯木景观构建技术。
In order to improve the ornamental and cultural benefits of deadwood resources in the landscape construction, taking the dead wood landscape of Erhai Lake in Dali, Yunnan Province as the object of evaluation, 26 typical landscape photos of dead wood were collected and adopted scenic beauty estimation method (SBE Method) and multiple linear regression analysis. The results showed that the contribution rate of dead wood was the largest, accounting for 41.30%, followed by dead wood, aquatic plants and original dead wood, accounting for more than 10.00% of the total dead wood, artistry of dead wood, dead wood, Less impact, the contribution rates were 6.33%, 5.52%, 5.42%. Based on the analysis of the contribution rate of landscape elements and the establishment of equations in the beauty degree model, the technical points of the construction of dead wood in Erhai Lake are proposed, including the location of dead wood, the planting pattern of dead wood, the art of dead wood and the technology of dead wood landscape construction.
