Unique Properties

Pan'an Lake National Wetland Park is located in Jiawang District, Xuzhou City, Jiangsu Province. The original intention of the construction was a comprehensive renovation project for ecological restoration and transformation of the Jiawang coal mining subsidence area, and then gradually developed into a collection of ecological wetland, cultural landscape, recreation and entertainment, and science education functions. All in one comprehensive scenic spot.

Dimensions & Packaging

(1) Restore soil vitality through soil reconstruction, and naturally restore damaged ecological environment through plant growth; (2) The formation of distinctive land and water spaces, and the interaction between man and nature: the project forms a criss-crossed water space with rich scales and levels by connecting the north and south water systems, attracts birds with aquatic plants, and sets up sightseeing routes for cruise ships. Set up bird watching platforms to fully realize the interaction between man and nature; land space uses native plants to form a planting structure of arbor, shrub and grass communities, and adopts the usual natural and wild plant landscape matching form of wetland parks, and at the same time, the space is dense and artistic. Chemical treatment; (3) In order to ensure that the habitat can continue to play its ecological function, the outer control area is mainly agricultural forest land to form a natural base, and a specific conservation area is established inside to ensure its natural growth. The tortuous plank road surrounding the area construction does not enter, in order to reduce the destruction of human factors to the wetland habitat; (4) The project using "leaves blank" method to design spaces, and creates event venues but does not define the content of the event, returns this right to the user, which naturally forms a variety of event content: people spontaneously enter the open lawn to enjoy the sun, hold a picnic; hang wind chimes on the promenade; after the epidemic, bring the Internet celebrity "ground stall" project to the open space of the square.

Production Technology

The project insists on the combination of subsided land remediation and ecological restoration. Soil is the foundation for all natural habitats, so the first step to awaken this land is to restore the vitality of the soil: the project comprehensively analyzes the different conditions of the subsidence area, such as soil type, structure, stability, and depth of water accumulation, and mainly uses it for the land Soil reconstruction techniques such as "digging high and filling low, digging deep and filling shallow, stripping of cultivated layer, and layered staggered backfilling" were used to transform soil to restore soil fertility; and the Bulao River and Tuntou River that run through the north and south, forming circulating water The water system provides continuous nourishment of the wetlands and maximizes the purification effect of the wetlands on urban water quality. Then use the purification and ecological functions of plants to gradually restore biodiversity, create a healthy ecosystem, and adopt a hierarchical structure for protection in the overall plan: the outer control area is mainly agricultural forest land to form a natural base, and in the core area establish wetland conservation areas to ensure the sustainable ecological effects of the park.

Design Challenge

Due to coal mining for many years, most of the land in the Jiawang District where the project is located has long suffered from foundation collapse, pits and ponds, overgrown grass, and harsh environment, which left a heavy historical wound on the local area. This also indicates that the ecological restoration of the coal mining subsidence area in Pan'an Lake Wetland Park is an extremely long process. The project adopts the form of green spreading of landscape to reconstruct the ecological environment, and the use of vegetation, water system and other natural methods to purify and restore is undoubtedly the most sustainable way and greatly saves construction costs. However, the operation and management of wetlands still require long-term investment of manpower and material resources. For Jia Wang, Pan’an Lake Wetland Park is a large-scale investment project in history. Despite government support, the funding gap is still large. In order to ensure the normal implementation of the project, Jiawang District has overcome numerous obstacles and broadened financing channels, which has brought the overall assets and operation of the wetland park into a virtuous circle.

Research

From the perspective of practical verification, the design is based on the original intention of restoring the ecological environment of the collapsed area, seeking sustainable development and harmony between nature, culture and life on the site. The process of landscape design and restoration is carried out by linking water systems, soil modification, vegetation coverage and other means to create a wetland landscape with water as the core, and to carry out plank road viewing, boat cruises, fruit picking, animal observation, etc. according to time and place Activities make people fully interact with nature. At the same time, with the theme of rural activities, leisure experience, and production return, the construction of traditional architecture is reproduced, the folk customs of the local villages, the development of homestay, tourism, ecological health care and other industries, arouse homesickness, build a complete wetland service system, and achieve considerable You can have fun. Therefore, it can be said that Pan’an Lake Wetland Park is a landscape that naturally grows from the land. After 8 years of development, it has successfully driven the industrial transformation of Jiawang District after coal mine resources have been exhausted, and has also formed good ecological and social benefits.

Inspiration

The value of the project is that it has implemented the concept of sustainable development for the wetland park eight years ago. It is not about overthrowing, stripping and rebuilding, but after completing the transformation of the soil, using the absorption and purification effect of plants to spread it in green The form gradually covers the site with the landscape, purifies the environment, repairs the devastating damage to the land.

Project Duration

The project started in January 2011 in Xuzhou and finished in August 2011. The total planned area is 52.89 square kilometers, including 16 square kilometers of the core area.

Operation Flow

The project takes the wetland ecosystem as the core of the design and creates two types of ecological spaces: water and land: by linking north and south water systems to form criss-crossing water spaces with various scales, aquatic plants embellish and shelter to outline the spatial relationship and attract birds. Created the graceful aquatic which people can go boating through it. The land space uses native plants to form a planting structure of arbor, shrub and grass communities, adopting the usual natural and wild plant landscape matching form of the wetland park, and at the same time, the space is dense and artistic. The 1-km-long zigzag wooden plank road runs through the water and land space, and a bird watching platform is set up to fully realize the interaction between man and nature. The project establishes the connection between man, nature and local culture, reproduces the ancient charm of Jiangnan architecture and folk customs in northern Jiangsu, shows the cultural heritage of Pan’an, develops tourism and vacation, homestays, ecological health care, improves wetland amusement services, and makes the park truly a city The carrier of public activities.
