Tropic of Cancer on Earth in 16 countries and regions, mostly desert and grassland areas, such as North Africa, the Sahara, the Arabian desert of the Arabian Peninsula, India and Pakistan 's Thar Desert, North America, Mexico desert, etc. , the so-called "return to the desert with " only through the region Yunnan、Guangxi、Guangdong and Taiwan provinces of our country, but it is an entirely different story. This area lush forests, lush, abundant rainfall, abundant species, known as the "magic of the return belt ."

The annual average rainfall in Taiwan is around 2,500 mm, which is 3 times the world's average. However, the annual average accessible water per person in Taiwan is only 1/6 of the global average. Which makes Taiwan the 18th most water-shortage areas in the world. As the world's 2nd populated country, Taiwan also has the problem with the water usage. Due to its steep landforms, the rivers in Taiwan are short and rapid. Therefore, most of the rainwater rushes into the ocean directly. Plus the irregular training rain the year, only 26% of the annual rainfall are usable.

Highway systems are necessary for well-developed countries, yet also become the urban area separation lines that block people’s rights to walk and cut down ecological development. Junctions of highways are forgotten or unattractive spaces. These large amounts of highway infrastructures can be used as buffer zones, becoming traffic junctures that are conducive to the urban environment, as well as important zones for urban ecological development.

Inappropriate sewage treatment of industrial areas in the base will severely impact the water quality of neighboring wetlands. Therefore, we want to replace traditional sewage treatment factories with plants and new pumps, to achieve filtering effects with systematic architecture levels. Using solar energy for basic power generation and new pumps to draw sewage, these buildings have green belts consist of plants from top to bottom for water filtration, so as to effectively achieve functions of water purifying system.

Landmark high-rise buildings going through the network of highway junctions will be formed, while the streamline of these buildings will guide rainwater into the water storage area for routine filtration work. With bottom layer as a footpath to cross the highway, and the top layer providing an ecological area for birds to inhabit, these buildings will form a sky ecological network and practice the concept of symbiosis between human and nature.

北回歸線經過地球上16個國家和地區，多屬沙漠和草原地帶，如北非的撒哈拉沙漠，阿拉伯半島的阿拉伯沙漠，印度巴基斯坦的塔爾沙漠，北美的墨西哥沙漠等等，出現所謂“回歸沙漠帶”，唯有經過雲南、廣西、廣東、臺灣四個地區，卻是另一番景象。這一帶林木繁茂、鬱鬱蔥蔥、雨量充沛、物種豐富，人們稱之為“神奇的回歸帶”。

台灣年平均降雨量約有2,500毫，為全球平均的3倍。然而，台灣的人每年平均可獲得的水量，僅為全球的1/6，是世界第18位的缺水地區。因台灣地狹人稠、人口密度高居世界第二，且地形陡峭、河川短促、水流湍急，大部分雨水直接流入大海`，在加上降雨時空分布不均，實際可用水量僅年降雨量之26％左右。

在開發完整的國家高速公路的系統是必需的，而公路卻造成了城市區域的分隔線，阻隔了人們步行的榷力，以及切斷生態發展。公路交界處是被遣忘或沒有吸引力的空問，這些大量的公路基礎設施，可作為緩衝區的土地條件使用，不僅成為交通節點和城市環境的可能性之外，更能成為城市生態的重要發展區域。

基地的工業區不當污水處理，嚴重影響到基地鄰近的溼地水質。因此我們希望以植物和新型幫浦來替代傳統的汙水處理廠，並透過系統化的建築層級來達到過濾效果。建築以太陽能作為基礎發電，利用新型幫浦來抽取汙水，進而由上往下的植物綠帶層過濾水源，來達到有效的淨水系統功能。

透過高速公路交匯處的網絡，成為一個視覺標誌性的高層建築，建築的流線型能將雨水引導到儲水區，有助於日常的濾水作業。而建築下層提供人們穿越高速公路的步行區，建築上層提供烏類棲息的生態區，成就天空生態網路，實踐自然與人類的共生概念。
