导语

INTRODUCTION

人与水的情感似乎自古以来就是复杂又矛盾的。人类一方面依赖水，渴望亲水、近水，一方面却又惧水、畏水。随着社会的发展及生活方式的改变，人们通过禁锢河流的方式获得居于水边的安全感。这看似获得了对自然的控制力，但也同时丧失了人类记忆中对水那份宝贵的情感。唤醒沉寂的河流，让河流回归城市生活，才是我们当下更好的选择。

初见

SITE IMPRESSION

项目位于南京市浦口区永宁镇区西侧，属于老山的行洪通道之一。初到项目现场，河道两侧高大而灰冷的防汛墙令设计团队望而生畏，巨大的高差从空间上隔绝了全部可安全观望溪流的视线。而溪流本身也因为缺乏有效的保水措施几乎很难被感知到，即便局部有一定体量，浑浊的水体也无法吸引人去多看一眼。沿着防汛实墙顶小心翼翼的前行，我们不禁感慨：在以促进工业发展和经济发展为第一需求的时期所采取的防汛措施，虽然解决了这个城镇安全抵御洪水的问题，但同时也隔断了河道与周边场地的物质交换，割裂了居民与水的生活情感交流。这显然不符合新世代的审美导向和实际需求。

The project is in the west of Yongning Town, Pukou District, Nanjing City, serving as one of the flood passage of Laoshan. The detachment of the safe overlooking waterscape was apparent with the giant and gray flood walls demarcating huge elevation difference. The stream itself was hardly perceptible because of the lack of effective water conservation measures. Even if there is a certain volume of water in some places, the turbid water cannot attract people to appreciate. The concrete channel built in the past have solved the problem of safe flood resistance in this town for industrial and economic development purpose, but the material exchange between the river and the periphery was blocked, and the connectivity between neighborhoods and safe use of the creek was missing. The concrete canal was in dire need of an upgrade for new aesthetic and functional requirements.

设计构思 DESIGN CONCEPT

受用地规划的限制，可供我们操作的空间是有限的，但我们不满足于按照一个“形象工程”的标准使其仅仅达到整洁，美观，而是希望在保障行洪安全的前提下，通过生态修复系统手段缝合河道两侧被割裂的空间，力求水利设施景观化，景观设施艺术化，重新诠释人与水，水与城之间无界共生的关系。

The project was challenging because of the land use and the space limitation. The design goal was not only to make the creek reach the aesthetic standard of clean and beautiful, but also to sew up the separated space by ecological restoration method on the premise of ensuring the safety of flood discharge. The project makes water conservancy facilities landscape and landscape facilities artistic, reinterprets the relationship between human and water, water and city.

簇溪生长——兴镇

DEVELOPING ALONG THE RIVER: TOWN REVITALIZATION

近水却不能亲水，一个蓬勃发展的小镇不应有这样的遗憾。巨大的高差原本对亲水需求是一种限制，但在设计师眼里却可以为实现多维度立体化的交通系统创造可能。蜿蜒的小路在场地里延展开来，将人们从周边质朴的街市引入一个水绿交融的所在。无需过多指引，便可本能地向着更滋润、更灵动的场所走去。绿地、花草、溪水、小径，有限的空间中流露出的是蓝绿空间的无界交融。这里不再是一个无人问津的荒芜之地，开放的河道空间可以满足城市不断增长的多元化需求，为创造繁荣宜居的小镇带来了更多的期待。

The thriving town was close to water, but the high elevation difference limited the water interaction requirements. Instead, it created opportunities for multi-dimensional slow traffic system. The winding path designed in the site attracts visitors to enter spontaneously from the outside area into the water landscape. Blue and green space integrates together with landscape elements including grassland, flowers, streams, and paths. The site was no longer an inaccessible place after the redevelopment. The open water space can act beyond the dynamic requirements of urban functions, to bring a prosperous and livable future for the town.

慢城生活——人和

SLOW LIFE: HUMAN HARMONY

我们一方面通过慢行交通系统将滨水空间的体验和影响外延到河道之外，另一方面通过场地的设计向河道内部融入市民生活的日常。你既可以在挑出的平台上驻足远眺，亦可以在溪流漫滩中纵情自然。我们希望场地内所呈现的景观不仅可以使人与自然环境间的对话变得和谐有趣，还可以为小镇居民释放足够的交流与倾诉空间，延展生活的尺度，让原本封闭荒芜的河道空间充满生机与活力。

On the one hand, the design extends the experience and influence of waterfront space to the outside of the river through the slow traffic system. On the other hand, it connects the citizens’ daily life with the river. Visitors can not only enjoy the scenery on the platform, but also immerse in nature. The landscape aims to promote harmonious and interesting interactions between people and the natural environment. The project transformed the closed and desolate river space beyond its function of drainage, into vibrant, new public space for communication and recreation.

碧水川流——理水

CLEAN AND VIBRANT RIVER: WATER MANAGEMENT

我们尊重河道本身行洪的功能需求和因季节而变化的水文特征，在与水利设计师经过多次碰撞与反复推算复核后，确定了将原河道改造成为“主河槽+浅水溪流”的断面形式。主河槽用以作为行洪泛洪的弹性空间，保障极端天气下的水安全；浅水溪流则用以改变水系平面形式，形成近自然的河流形态。

但另一个棘手的问题又出现在设计师面前，即如何应对周期性的洪涝对河道绿地坡面的冲刷？经过多次讨论，我们结合生态工法和传统工程材料，在不利用任何大型机械和混凝土的前提下，通过三维土工格室力学上的特性及木桩与卵石搭配使用，对水陆边界和河道漫滩进行了土壤的加固处理，同时结合植物的应用来解决这一难题。

改造后的河道两侧绿地高低起伏，向蜿蜒曲折的溪水中缓缓延伸，增大纳洪空间的同时，实现了水绿空间的自然过渡。

“水净”的实现得益于率先启动的控源截污工程及两岸丰富多样的水生植物；“水丰”则倚靠我们为此项目量身定制的多层级水循环方案。

我们旨在通过一系列基于自然的解决方案，提高水体流动性，恢复河道空间的生态基底，建立一个具有自我调节和自我修复功能的防御系统。

The design embraces the flood discharge demand of the channel and the seasonal changing of hydrological characteristics with the main channel + shallow creek section design. The main channel works as a resilient space for flood discharge to ensure water safety in extreme weather, while the shallow creek replicates the diverse flow patterns which are characteristic of natural river systems. Another challenge for the site is the periodic fresh water flush to the green slope. The design combined the bioengineering techniques with the typical engineering technologies which the plants have an important structural role in soil reinforcement on the water land boundary and the floodplain using no large machinery and concrete, through the mechanical characteristics of three-dimensional geocell and the simultaneous application of pile and pebble. The undulating green space along the river gently integrates to the meandering stream after the redevelopment, increasing the floodwater conveyance capacity and creating transitional water and green space. The success of water clean was attributed to the pollution control and interception project and the rich and diverse aquatic plants along the banks. The water storage relied on the multi-level water circulation scheme tailored for this project. Nature-based Solutions were involved to improve the fluidity of water and restore the ecological base of the river, increasing the resiliency of the site with self-remediation capacity.

后记

SUMMARY

这是一次具有“突破”意义的项目实践活动。我们从思维上打破了固有的应对洪水的思维定式，应用“调合共生”的理念实现蓝绿空间的无界交融，让河流重新焕发生机，回归城市生活。

The project has achieved a significant breakthrough for flood control design thinking, which applied the concept of ‘harmony and symbiosis’ to blur the boundaries of blue and green space, to regenerate the river and bring water back to civic life.

我们希望通过基于自然的解决方案，构建生态蓝绿系统，营造生态修复的特质空间，引导触发城市活力发展。我们期待江北新区玉兰河能够赋予小镇更多的活力，带来精神上的重生，引导生态公众意识提升，使居民近水更亲水，亲水且乐水。

The vision of the project was to create an ecological blue-green system based on Nature-based solutions, build a special space for ecological restoration, and revitalize city development. It is hoped that Yulan River in Jiangbei New District can bring vitality to the town, develop the public awareness for ecology, and make the residents reunite with the waterfront.
