【摘要】：本论文在调查诸城城镇森林的现状基础上,利用美景度评价法(SBE)对不同类型的城镇森林群落的林内景观和林外近景观分别进行评价,通过评价选出SBE美景度高的城镇森林景观类型,分析不同类型城镇森林景观的主要影响因素,建立不同类型森林景观的美景模型,分析主要的构景要素与城镇森林景观美景度的关系;选取典型的城镇森林景观进行生态功能的分析,选出生态功能最好的群落结构,结合美景度的评价最后得出不同群落类型的优化配置模式,为诸城城镇森林的规划布局、树种选择、群落结构调控及景观提升提供技术支持。在诸城分别选择了不同类型的森林景观,其中山地林景观3种类型,河岸林景观8种类型、围村林景观8种类型、道路林景观15种类型。美景度评价的主要研究结果如下:(1)在山地林景观中,美景度最高的为板栗林,林内景观的美景模型为SBE=-1.059+0.315×x6+0.095×x9,影响山地林林内景观美景度的主要构景要素为乔木丰富度(x6)、乔木平均树高(x9);影响林外近景观的构景要素为树冠质地和树冠层次。(2)在河岸林景观中,美景度最高的为朱泮一村以杨树为主的河岸林,林内景观的美景模型为SBE=-0.389+0.109×x8+0.236×x13,影响其美景度的主要构景要素是林下植被覆盖度(x8)、乔木平均枝下高(x13);林外近景观的美景模型为SBE=-0.263-0.424×x3-0.494×x6+1.055×x9,影响其观美景度的主要构景要素是斑块可辨性(x3)、树干清晰度(x6)、色泽明度(x9)。(3)在围村林景观中,美景度最高的为大李子园村以杨树为主的围村林,林内景观的美景模型为SBE=-0.266+0.253×x10+0.053×x13,影响其美景度的主要构景要素是郁闭度(x10)和乔木平均树高(x13);林外景观的美景模型为SBE=4.717-1.037×x4-1.804×x8,影响其美景度的主要构景要素是斑块形状(x4)和树冠层次(x8)。(4)在道路林景观中,建立的景观模型为SBE=-0.301+0.107×x1+0.298×x4+0.088×x5+2.726×x9-1.746×x10-0.124×x13+0.525×x14,影响道路林景观美景度的主要构景要素是色彩丰富度(x1)、生活型(x4)、生长状况(x5)、林下植被覆盖度(x9)、郁闭度(x10)、乔木平均树高(x13)、乔木平均枝下高(x14)。在不同类型的城镇森林景观中选择几种典型的森林群落类型,调查分析其生态服务功能。测定的指标分别为:空气温度、空气湿度、太阳辐射、土壤温度、土壤含水量、空气负氧离子、PM2.5、PM10。每种林型包括林外、林中、林内三个重复,最后得出生态服务功能最好的群落。基于上述对不同类型森林群落的美景度评价、建立景观评价模型、分析生态功能的基础上,分别对山地林、河岸林、围村林、道路林这几种森林群落从植物选择和植物配置上提出一种典型的优化模式,这也是本文的创新点。生态功能在森林建设的过程中也有着很重要的作用,应加以重视。将美景度与生态服务功能结合,能够更好的为诸城城镇森林的规划布局、树种选择、群落结构调控及景观提升等提供技术支持。
[Abstract]:Based on the investigation on the status quo of Zhucheng urban forest base, using the SBE method (SBE) for urban forest communities in different types of forest landscape and forest landscape near were evaluated through the evaluation, choose the SBE beauty of high degree of urban forest landscape types, analysis on the main influencing factors of different types of urban forest landscape, the establishment of beauty the model of different types of forest landscape, landscape elements and analysis of constitutive relationship of urban forest landscape of the main analysis; selection of urban forest landscape typical ecological function, community structure, ecological function select the best, with the evaluation of the degree of beauty finally reached the optimal allocation model of different community types, planning layout, urban forest in Zhucheng the selection of tree species, community structure and landscape to enhance the regulation to provide technical support. The different types of forest landscape in Zhucheng were selected, including mountain 3 types of forest landscape and riparian forest landscape 8 types, 8 types of village forest landscape, forest landscape road 15 types. The main research results are as follows: the evaluation of the degree of beauty (1) in the mountain forest landscape, beauty is the highest beauty of Chinese chestnut forest, forest landscape model for SBE=-1.059+ 0.315 * x6+0.095 * x9, the main effect of landscape structure landscape beauty in the mountain for the tree species richness (x6), tree average height (x9); effects of forest landscape in landscape elements as the canopy texture and canopy level. (2) in riparian forest landscape, the beauty of the highest degree of a pan Zhu Cun to poplar based riparian forest, forest landscape beauty model is SBE=-0.389+0.109 * x8+0.236 * x13, main landscape elements constitute the degree of beauty is under forest vegetation coverage (x8), the average tree height under branch (x13); the beauty of landscape forest near model for SBE= -0.263-0.424 * x3-0.494 * x6+1.055 * x9.
