【摘要】 泰山是我国的历史名山,其风景林是泰山风景的重要组成部分,泰山登天景区集优美的自然景观、无与伦比的历史文化遗存与典型的地质遗迹的完美结合,是泰山旅游的必经之路。本文在搜集整理泰山风景林资料基础上,采取以线路两侧调查为主,通过实地踏查、典型风景林样地调查(树种组成、树木胸径、活枝下高、树高、冠幅等)的方法,摸清了泰山登天景区风景林的资源状况和生长现状。同时通过拍摄风景林样地照片,制成幻灯片,让评价者按十分制(0-9)对每张幻灯片打分,然后将评分值进行标准化处理的方法,得到了美景度值——SBE值。对各景观要素进行分解,以SBE值为因变量,各要素值为自变量,建立与美景度相关的模型,找出影响泰山风景林景观美感的主要景观要素。结果分述如下:1.对泰山主要的观赏树种资源进行了分类整理,从观赏的角度将泰山的观赏树种分成了观叶、观花、观果、观形四大类;从生态学和美学的角度对泰山的风景林树种资源进行了评价。认为泰山风景林还应进一步丰富树种,并对现有林分进行改造,特别应绿化现有裸地,使形成不同景观斑块。2.对泰山登天景区样地调查结果进行分析,表明:泰山登天景区风景林林分密度过高,限制了树木的生长,林内多为小径级、小冠幅树木,使得林分的美感度大大降低。相对于针叶树油松、侧柏,阔叶树麻栎、栓皮栎、刺槐、五角槭有着较高的胸径、冠幅和明显的色彩变化。3.摸清了登山登天景区的风景林主要树种分布情况。随着海拔的升高,树种种类逐渐减少。在海拔200～1000m,林分是以侧柏或油松为优势树种的混交林;海拔超过1000m,则是以油松为主的混交林。从风景林树种组成看,彩叶树种较少,主要是以油松、侧柏为主的常绿针叶树种。登山登天景区现存的大量古树名木时泰山历史文化的记录者,有着特殊的景观价值。4.通过比较各景观的SBE值,发现泰山登天景区各类型风景林的美景度值大小排序为:栎林﹤侧柏林﹤刺槐林﹤油松林﹤五角槭林﹤落叶松、赤杨混交林﹤栎柏混交林﹤落叶松林﹤峭壁侧柏油松林。5.模型模拟结果显示,影响泰山登天景区风景林景观的主要要素为:林下枯落物、胸径大小、郁闭度、林下层统一度。通过模型外要素与SBE值两两比较分析讨论,发现除了进入模型的四个变量外,树干排列、林下层高度、自然整枝、平均树高对泰山风景林的影响也较大。根据评价结果,认为应该加强对现有风景林资源的保护,小范围的增加彩叶乔木,同时保护和种植有一定观赏性的林下灌木,丰富泰山风景林的植物种类。而通过调查,发现风景林林分密度过大,树木胸径较小,而且影响了林分卫生状况。建议通过合理的疏伐,提高林内光照,培养大径级林木,改善林分的卫生状况,丰富树种,进行林分抚育,开发灌木资源提高林分的美景度,同时要加强保护古树名木。更多还原

【Abstract】 Mountain Tai has the most historical and natural view,its landscape forest is important part of Mountain Tai landscape. Heaven scenery zone in Mount Tai is most important tourism route which a perfect combination composed of typical geological heritages and beautiful natural scenery and unique historic heritages. By collecting materials, tread survey and investigating representative sample plots (trees species, diameter at the breast height, tree height, branching height and crown width etc.), investigated and analyzed resources and growth situation of Mountain Tai landscape forest. At the same time, photos of these plots were taken. Then the photos were estimated by college students and the scores of the photos were transformed into SBE value. Finally model was established between SBE cost and the landscape factors of the photos. Conclusions were as follows:1. Based on ornamental value, the tree species resources of the landscape forest of the mountain Tai can be classified four kinds, such as view-leafed plant, view-flowered tree, view-shaped plant, view-fruited trees. And the resource of landscape forest was evaluated from the angle of aesthetic and ecological.2. Discuss the relationship between the aesthetic of landscape forests and their forestry characteristic, such as density and main tree species. The forest density is so high as to limit the growth of trees. The broad leaved tree forest has the bigger diameter at breast height, crown width, variety of color than conifer.3. Studied the distributing of the main landscape forest tree species along Heaven scenery zone route of Mountain Tai, results showed that tree species decrease with different altitude gradients. From 200～1000 meters, the stands is the mixed forests which dominant species is Pinus tabulaeformi or Platycladus orientalis. Above 1000 meters, the stands are evergreen forests which dominant species is Pinus tabulaeformi. From the viewpoint of tree species composition, the main tree species in Mountain Tai are evergreen conifer trees; the colorful tree species are few. A lot of ancient and famous trees existing in heaven scenery zone of Mountain Tai is historical recorder and has special ornamental value.4. Compared the SBE value of the sights, the results showed that the order of the SBE value of the sights in heaven scenery zone heaven scenery zone is: Oakery﹤oriental arborvitae﹤Locust forest﹤Chinese Pine forest <Amur maple forest﹤mixed forest of larch and alnus﹤mixed forest of oriental arborvitae and Oak﹤larch forest﹤oriental arborvitae and Chinese Pine forest in the cliff.5.The modeling result shows that the main factors affecting the sight of landscape forest in heaven scenery zone of Mountain are litter, diameter at breast height, canopy density and the unitize degree of the under storey. By pair-wise comparison between surplus factors and SBE value analysis, the arrangement stock, the height of under storey, natural pruning and tree height also played an important influence to the aesthetic sight of the landscape forest.According to evaluation result, some proposals were pointed on: protecting the existing landscape forest resources; at the some time increasing colorful trees and ornamental shrubs; improving sanitation condition of forest; protecting ancient and famous trees; thinning high density stands; protecting and exploiting shrubs resources etc.更多还原
