Houtan Park

Houtan park is one of the core green spaces of Shanghai World Expo Park. It is located at the west end of "2010 Shanghai World Expo Park", between the East Bank of Huangpu River and Puming road. It is adjacent to the newly-built Puming road in the park in the south, Ni Jiabang in the West and Lupu bridge in the north, covering an area of 18 hectares. The site was originally the site of the iron and steel plant (Pudong Iron and Steel Group) and Houtan ship repair plant. It was designed by Professor Yu Kongjian of Peking University and led by the "native design" team in early 2007. It was completed in October 2009.

Houtan Park, built on the brownfield of the original industrial site, is a renewable ecological landscape along the Huangpu River in Shanghai. The park includes wetland, ecological flood control and beautiful riverside scenery.

Houtan park generally refers to Shanghai World Expo Houtan Wetland Park

Houtan Wetland Park of Shanghai World Expo is one of the core green landscape of Shanghai World Expo Park. It is located between the East Bank of Huangpu River and Puming road. It is adjacent to the newly built Puming road in the park in the south, to nijiabang in the West and to Lupu Bridge in the north, covering an area of 18 hectares. The site was originally the site of the iron and steel plant (Pudong Iron and Steel Group) and Houtan ship repair plant. It was designed by Professor Yu Kongjian of Peking University and led by the "native design" team in early 2007. It was completed in October 2009.

Historical evolution

The recorded history of the site and its surrounding areas can be traced back to the Tang Dynasty. Judging from the location of the coastline, the site had become a land before the 8th century (the reign of the Tang Dynasty). According to the historical records of Nanshi District where the site once belonged, the upper limit of memorabilia began from the Tang Dynasty. According to the changes of natural environment and social and economic characteristics, the changes of site landscape can be divided into three stages, namely, before written historical records, agricultural society, modern industry and modern industry. The change of the site tells the story of the development of the site and remembers the feelings of the people around.

Before written historical records, there was no agricultural production or administrative system.

In the period of agricultural society, the agricultural economy was dominant, and the fishery, salt industry and handmade textile industry were also developed. Under the jurisdiction of Shanghai county, it is a typical water village landscape.

Modern industrial period: one of the centers of modern industrial accumulation, with developed inland river shipping industry, dense docks, and developed railway and highway transportation.

Modern industrial period: the manufacturing industry has gone through the golden age, and the old factories are facing the problem of relocation or closing down. Pudong development requires closer ties between the two sides of the river. 　

present situation

The Inland River wetland has many functions. include:

< iwater purification system < / I

The inferior class V water of Huangpu River is purified to class III water by sedimentation, aeration and oxygenation, and purification of soil, plants and microorganisms in the process of slowly flowing through the wetland, which is used for landscape, irrigation and washing of the Expo site. The preliminary trial operation shows that the water purification capacity of Houtan park is 2400t per day. This is not only a practical water purification system, but also a display and popular science education system.

Purification process: from west to East, the wetland water flows through pathogen purification area, heavy metal purification area and nutrient purification area, and then enters into the water quality stable regulation area; during this period, the water flows in and out of the terraces through underground pipelines, and the water is purified in a circuitous way.

System design: the water level and longitudinal velocity of Huangpu River and inland river wetland are considered in the purification system; the ecological design of lake bottom provides conditions for water biodiversity; meanwhile, the sedimentation, oxygenation, filtration and biological absorption of water body are considered.

The water level is high in the West and low in the East; the river water level is high and the wetland water level is low, so the water flows naturally in the purification circulation system.

Ecological flood control system

A. A transition zone and buffer zone between the Huangpu River and the land are formed between the earth slope type flood dike with a return period of two years and the platform type flood dike with a return period of one thousand years, which can be used as the flood detention area of the city in case of sudden floods.

B. Layered embankment greatly reduces the required height and strength of the flood control embankment, so that the original cement flood control embankment can be changed into an ecological dike made of low-strength soil and natural materials, which improves the riverside ecosystem.

< I created a rich valley landscape < / I

On the narrow site, create rich space. The combination of the terrain of the inner Valley and the local trees on both sides creates a relatively quiet valley landscape, and creates a secluded place in the noisy environment. The valley is vertical from upstream to downstream, zigzag and changeable in spatial opening and closing, and horizontal from land to river, twists and turns, creating rich spatial levels on the narrow section.

< I Ditai river wind < / I

Luditai, with an area of about 1650 square meters, is located in the middle of Houtan park. The former sewage treatment plant wharf is 10 meters long and 8 meters wide. The whole wharf and foundation are reserved in the design and transformed into a leisure platform.

1. Retain the basic structure of the original freight terminal, and retain all the foundations, reflecting the characteristics of industrial heritage;

2. With bamboo and wood decks, local planting pools and other elements, a user-friendly rest system is established, which enables visitors to stay comfortably and overlook the original wetland landscape of Huangpu River and the skyline of Shanghai on the other side.

3. In order to prevent the wind from blowing, steel plates embedded with glass were erected on the platform. Reed and silver grass are planted at both ends of the platform and on the side near the water, integrating the platform into the riverside wetland, showing wild interest and nature.

design strategy

Regeneration design strategy can transform the original industrial site into an ecosystem, which will have comprehensive ecological functions: food production, flood control, water purification and habitat generation. It will be an innovative demonstration of ecological culture in 2010 Shanghai World Expo. 1. Wetland and regeneration design

On the natural base of the river beach, the four season crops in the south of the Yangtze River are selected, and the terrace construction and irrigation technology are used to solve the height difference and meet the effect of water storage and purification, so as to create urban countryside. In spring, the cauliflower is golden, in summer, the sunflower is shining, in autumn, the rice is fragrant, and in winter, the ground is swaying. All of these arouse the aftertaste of the local agricultural civilization in metropolis, which is the display of the production function of the land and the reconstruction of the connection between the urban people and the land. Besides water purification, the park also has the function of flood control. The flood dike is also "invisible" and hidden under the vegetation of Tiangu dike on both sides of the river basin. The flood dike at the outer end can prevent the flood with a return period of 50 years, while the inner one can prevent the flood with a return period of 100 years. When the flood comes, the whole wetland can be completely used as a buffer, and when the flood goes back, it can recover wet The function of the earth. 2. On the basis of natural river beach and urban countryside, heritage and scenery retain, reuse and regenerate the memory of the original site as a steel plant. The steel structure of the huge industrial plant is preserved and transformed into a three-dimensional garden and a bar recreation place; the original riverside wharf is preserved and designed into an ecological water garden and observation platform. Looking at the high-rise buildings in Puxi from afar, it seems that you are out of the world; a rust colored scroll made of steel plate is folded to write countless memories of vicissitudes. It rises and falls vaguely, floating on the water bank platform, or lying dormant on the ground to become a pavement, meandering away, or looking up in the air to become a canopy, window, skillfully taking the beautiful scenery in the garden. 3. A long and narrow valley space is arranged in the road system Park, which solves the problem of flood control skillfully. At the same time, it opens and closes, flows tactfully, and is nearly 2 kilometers long. A series of hydrophilic trestles, platforms and footpath network shuttling through the vegetation are designed. It begins with the waterfall wall and terraced fields at the west end, and ends with the colorful metal curtain. You can swim among them, or dive to the bottom of the valley to explore the water, with green reeds and frogs around your feet; or climb the platform to the deep, with reed flutes and colorful butterflies flying; or go into the mountains to explore the way, with forest paths and bamboo alleys deep, surrounded by caves; or go up to the open fields to see the lotus leaf fields, with rice and rice.
