| 摘要: | 對中正紀念堂中的陰影分佈進行模擬，研究將著重於樹高較高的喬木，樹高過低的樹木不具有遮蔭效果因而不計，樹木對研究區域中的行人提供的遮蔭效果，以中正紀念堂為例，比較中正紀念堂樹木的遮蔭分佈情形。
在越來越極端的氣候之中，城市中的樹木成為一個重要調節的角色，樹木提供的遮蔭成為主要的研究的素材，行道樹的外型、樹高、樹寬、枝下高都各有不同，本研究將分析研究區中的行道樹長寬高，枝下高，對基地範圍內樹木的樹木尺寸測量，並以模擬出的主要情況，並以該情況為基準，並且對這些樹木遮蔭的成效進行評估分析。
模擬出樹木在各個街道中產生的陰影情形，與使用者的關係、提供行人的遮蔭程度，提出哪些區域的使用者是受到較多的樹木陰影遮蔽的，以及基地範圍內良好遮蔭的區域，其內容會包含各個面向，除了樹木的遮蔭範圍以外，樹種特性、枝葉情形產生不同的可能性，其結果不會只有遮蔭範圍，遮蔭效果以及季節因素屬於重要考量，樹木可以在春天、夏天遮陽，提供行人遮蔭的空
間，在秋天、冬天的效果可能就是反效果，過多的樹木會導致不必要的風寒，基地內不同的樹木在各個區域具有不同的效果，好的樹木能提供較為有效的遮蔭，這些都值得探討。
In the modern environment, the shading effect of trees is becoming more and more important. In the study, the situation inside the Chiang Kai-shek Memorial Hall will be compared, and the shadow distribution in it will be simulated. The research will focus on trees with taller trees. Trees that are too low have no shading effect and are therefore ignored. The shading effect that trees provide to pedestrians in the study area takes the Chiang Kai-shek Memorial Hall as an example to compare the shading distribution of the trees in the Chiang Kai-shek Memorial Hall.
In an increasingly extreme climate, trees in cities play an important regulating role, and the shade provided by trees has become the main research material. The shape, height, width, and height of the street trees are all different. , this research will analyze the length, width and height of the street trees in the study area, the height of the branches, measure the tree size of the trees in the base range, and use the simulated main situation as a benchmark, and the shading of these trees Evaluate and analyze the effectiveness.
Simulate the shadow situation caused by trees in each street, the relationship with pedestrian walkways, the degree of shade provided to pedestrians, and propose which areas of pedestrians are shaded by more trees, and the areas with good shade within the base, Its content will cover various aspects. In addition to the shade range of trees, tree species characteristics and foliage conditions may produce different possibilities. The result will not only be shade range. Trees can be used in spring, Shade in summer and provide shade space for pedestrians.
In autumn and winter, the effect may be the opposite. Too many trees will cause unnecessary wind and cold. Different trees in the base have different effects in different areas. Good trees can provide more Effective shade, these are worth exploring. |
