架构师提供的文本描述。Kew花园的树顶人行道于2008年5月24日，也就是Kew的树年，向9，000多名游客开放。这条人行道是一种令人兴奋的体验，它带着18米高的游客进入树冠，俯瞰Kew的鸟瞰，从树叶的宁静中洞察树木在我们呼吸的星球中的特殊作用，以及落叶林地及其居民的亲密景色。这条人行道的灵感来自于自然界中反复发现的古代斐波纳契序列。

Text description provided by the architects. Kew Garden's Tree Top Walkway opened on 24th May 2008, Kew’s Year of the Tree, to over 9,000 visitors. The Walkway is a thrilling experience, taking visitors 18m high into the tree canopies for a birds-eye view of Kew, providing insights into the special role of trees in our breathing planet and the intimate views of a deciduous woodland and its inhabitants from within the tranquillity of the leaves. Inspiration for the walkway was drawn from the ancient Fibonacci sequence found repeatedly in nature.

与随身听一起，还附带了一个地下的“Rhizotron”展览空间，探讨与树根生物学、气候变化以及树根与微生物之间的关系有关的各种主题。它的出现灵感来自于地球内部的自然裂痕，它揭示了一个充满刺激和教育内容的黑暗而充满活力的空间。

In conjunction with the Walkway, an underground ‘Rhizotron’ exhibition space is attached and which explores various themes associated with tree root biology, climate change and the relationship between tree roots and microorganisms. Its appearance is inspired by a natural cracking within the earth to reveal a dark and dynamic space rich with exciting and educational content.

马克·巴菲尔德建筑师设计这条人行道是为了在视觉上显得轻盈、谨慎，在自然环境中很自在；同时，也是一种厚颜无耻的人造建筑。他们决定将这种结构与扶手支架相结合，并借鉴斐波纳契序列，这是自然界许多增长模式的基础。通过使用与序列相关的累进数列(1，1，2，3，5，8，13，21，34等)，我们能够沿着典型的人行道桁架创建一个“Fibonacci网格”，从而使桁架附近的单元密度更高，那里的垂直荷载最高。

Marks Barfield Architects designed the walkway to be a visually light, discreet presence, at ease in its natural surroundings; while at the same time being unashamedly man-made. They decided to integrate the structure with the handrail support and drew on the Fibonacci sequence, which underlies many growth patterns in nature. By using the progressive series of numbers associated with the sequence (1,1,2,3,5,8,13,21,34, etc), we were able to work to create a ‘Fibonacci grid’ along a typical walkway truss, resulting in a higher density of elements near the trussends where the vertical loads are highest.

一个主要的挑战是在使游客尽可能接近树冠和注意地下复杂的树根系统之间取得平衡。为了了解建议的塔架和桩基础位置的树根活动程度，进行了一次雷达调查。这使得12-18米长的混凝土桩在主根之间的战略定位，确保了树和人行道的安全和长寿。

A major challenge was to strike a balance between enabling visitors to get as close as possible to the tree canopies and being mindful of the complex tree root system below ground. A radar survey was undertaken to understand the extent of tree root activity at the proposed pylon and pile foundation locations. This enabled strategic positioning of the 12-18m long concrete piles between the major roots ensuring safety and longevity for the tress and walkway.
