功能性景观构架 ECOLOGICAL INFRASTRUCTURE （简介.详细内容请 AS THE BASIS FOR A DESIGN 参考英文文本） FRAMEWORK Ecology is the main driver of our proposals for the Olympic Green, influencing the design of the site at multiple scales. As described previously in this book, Beijing faces major water scarcity and pollution issues, and a majority of residents lack access to high-quality open space. We propose repurposing the Olympic Park as a self-sustaining space that does not rely on the city’s traditional water and sewer infrastructure, and which creates a model for a more sustainable and resource-conscious Beijing. We identify the existing canal as the starting point to our ecological infrastructure. The canal currently extends southward from the main pond in Forest Park through the Olympic Park site, and is crossed at three points along this trajectory by three vehicular roads. While the canal provides an excellent starting point for an ecolgical infrastructure due to its length and placement in the site, there are three problems with it as it exists. First, the watershed and topography of the site do not respond to or interact with the canal. Second, humans are disconnected from it – the only way to view the canal is from above, and the pedestrian promenade along its edge does not provide an enjoyable landscape and is furthermore in poor condition. The eastern side of the canal is entirely inaccessible to the public. Third, and most importantly, the canal is unable to function ecologically because it is concrete-lined, preventing water from infiltrating back into the dwindling groundwater table.

生态与景观设计是本方案的主要元素，在多个层 面影响着整个场地设计。如前面的章节所述，北 京面临着水资源稀缺和水污染的双重问题，城市 居民缺乏良好的绿色休闲场所。在我们的方案试 图将奥林匹克公园改造为一个有机的生态系统， 不仅在公园中建立多样性的生态景观和生态体 验，并且选取公园中的重要节点来营造示范性的 水处理设施与滨水公共空间。 目前奥林匹克公园中的人工水道并没有与场地中 的其他功能行程良好的生态互动。另外，水系的 边缘缺乏以人为本的设计细节。最重要的是，由 于水岸边缘的设计很大程度上无法形成动植物栖 息地，因此人工水系并无法发挥相应的生态功 能。
