1. 项目陈述

Project Statement

一个城市垃圾场被改造为一个基于自然的水生态修复实验性景观。设计通过将几种不同的人工湿地结合在一起，形成沉浸式的生活景观，且在项目中还可以观察并量化设计与生态系统性能之间的相关性，同时提供探索和教育的功能。该项目展示了基于自然的途径如何净化废水和修复棕地，并提供生态系统服务、科学研究，及审美启智功能。

An urban waste dump has been transformed into a designed experiment: a nature-based wastewater remediation system. Several types of constructed wetland were combined to form an immersive living landscape in which the correlations between design variables and ecosystem performance can be observed and quantified, while simultaneously yielding a landscape for exploration and education. The project showcases how wastewater and land can simultaneously provide clean water, ecosystem benefits and scientific data, as well as beauty.

2. 场地挑战和目标

Site Challenges and Objectives

几十年来，钢铁和煤矿等重工业的需求和发展造成了这个城市的缺水与污染。为促进城市的绿色发展，邯郸获得了河北省第四届园林博览会，即邯郸园林博览会主办资格。通过层层筛选，土人设计很荣幸赢得了邯郸园博会的设计竞标，受托设计这个原本遍布煤灰、垃圾和固体废物的325公顷“废地”。

For decades, the city Handan suffered water shortages and pollution caused by the demands and impact of heavy industry, including steel and coal. As one part of its green development campaign, the city won the competition to host Hebei Province’s 4th garden expo——the Handan Garden Expo 2020. The landscape architect won the design competition and was commissioned to design the overall landscape, which covers 325 hectares on a site that formerly was primarily used for dumping coal ash, garbage and other solid wastes.

“清渠如许”的设计属于邯郸园博会的设计亮点，占地10.4公顷的梯田旨在展示基于自然的途径在废水净化和固体废物回收方面的潜在力量。该场地原本为城市垃圾和污染物堆成的20米高的小山，毗邻20公顷的退化湿地。万幸的是，设计前调查表明，现场没有有害物质对未来游客没有潜在的健康风险。

The Wastewater Purification Terraces were designed as one part of this grand show. Covering an area of 10.4 hectares, the terraces are intended to be a demonstration of the potential power of nature-based solutions for cleaning wastewater and recycling solid waste. The site is a 20-meter high mound, made of urban waste and debris, and is adjacent to a degraded wetland of 20 hectares. A pre-design site survey indicated that there are no hazardous materials on site and therefore no potential health risk for future visitors.
