【摘要】：本論文在調(diào)查諸城城鎮(zhèn)森林的現(xiàn)狀基礎(chǔ)上,利用美景度評價法(SBE)對不同類型的城鎮(zhèn)森林群落的林內(nèi)景觀和林外近景觀分別進(jìn)行評價,通過評價選出SBE美景度高的城鎮(zhèn)森林景觀類型,分析不同類型城鎮(zhèn)森林景觀的主要影響因素,建立不同類型森林景觀的美景模型,分析主要的構(gòu)景要素與城鎮(zhèn)森林景觀美景度的關(guān)系;選取典型的城鎮(zhèn)森林景觀進(jìn)行生態(tài)功能的分析,選出生態(tài)功能最好的群落結(jié)構(gòu),結(jié)合美景度的評價最后得出不同群落類型的優(yōu)化配置模式,為諸城城鎮(zhèn)森林的規(guī)劃布局、樹種選擇、群落結(jié)構(gòu)調(diào)控及景觀提升提供技術(shù)支持。在諸城分別選擇了不同類型的森林景觀,其中山地林景觀3種類型,河岸林景觀8種類型、圍村林景觀8種類型、道路林景觀15種類型。美景度評價的主要研究結(jié)果如下:(1)在山地林景觀中,美景度最高的為板栗林,林內(nèi)景觀的美景模型為SBE=-1.059+0.315×x6+0.095×x9,影響山地林林內(nèi)景觀美景度的主要構(gòu)景要素為喬木豐富度(x6)、喬木平均樹高(x9);影響林外近景觀的構(gòu)景要素為樹冠質(zhì)地和樹冠層次。(2)在河岸林景觀中,美景度最高的為朱泮一村以楊樹為主的河岸林,林內(nèi)景觀的美景模型為SBE=-0.389+0.109×x8+0.236×x13,影響其美景度的主要構(gòu)景要素是林下植被覆蓋度(x8)、喬木平均枝下高(x13);林外近景觀的美景模型為SBE=-0.263-0.424×x3-0.494×x6+1.055×x9,影響其觀美景度的主要構(gòu)景要素是斑塊可辨性(x3)、樹干清晰度(x6)、色澤明度(x9)。(3)在圍村林景觀中,美景度最高的為大李子園村以楊樹為主的圍村林,林內(nèi)景觀的美景模型為SBE=-0.266+0.253×x10+0.053×x13,影響其美景度的主要構(gòu)景要素是郁閉度(x10)和喬木平均樹高(x13);林外景觀的美景模型為SBE=4.717-1.037×x4-1.804×x8,影響其美景度的主要構(gòu)景要素是斑塊形狀(x4)和樹冠層次(x8)。(4)在道路林景觀中,建立的景觀模型為SBE=-0.301+0.107×x1+0.298×x4+0.088×x5+2.726×x9-1.746×x10-0.124×x13+0.525×x14,影響道路林景觀美景度的主要構(gòu)景要素是色彩豐富度(x1)、生活型(x4)、生長狀況(x5)、林下植被覆蓋度(x9)、郁閉度(x10)、喬木平均樹高(x13)、喬木平均枝下高(x14)。在不同類型的城鎮(zhèn)森林景觀中選擇幾種典型的森林群落類型,調(diào)查分析其生態(tài)服務(wù)功能。測定的指標(biāo)分別為:空氣溫度、空氣濕度、太陽輻射、土壤溫度、土壤含水量、空氣負(fù)氧離子、PM2.5、PM10。每種林型包括林外、林中、林內(nèi)三個重復(fù),最后得出生態(tài)服務(wù)功能最好的群落�；谏鲜鰧Σ煌愋蜕秩郝涞拿谰岸仍u價、建立景觀評價模型、分析生態(tài)功能的基礎(chǔ)上,分別對山地林、河岸林、圍村林、道路林這幾種森林群落從植物選擇和植物配置上提出一種典型的優(yōu)化模式,這也是本文的創(chuàng)新點。生態(tài)功能在森林建設(shè)的過程中也有著很重要的作用,應(yīng)加以重視。將美景度與生態(tài)服務(wù)功能結(jié)合,能夠更好的為諸城城鎮(zhèn)森林的規(guī)劃布局、樹種選擇、群落結(jié)構(gòu)調(diào)控及景觀提升等提供技術(shù)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.
