The project is located in ELITE CITY, Shizhong District, Jinan City, Shandong Province. Within ELITE CITY, there are three mountains: Quanzi Mountain, Aozi Mountain and Wanghualou Mountain, which were originally quarrying areas. Poor management in the early stage and the long-term mining of stone and limestone has resulted in multiple mining pits and dilapidated mountain body, which not only severely damages biodiversity and ecological environment but also poses a risk of landslides and falling rocks. In addition, the terrain of ELITE CITY is high in the east and south and low in the west and north. There are dozens of naturally formed flood discharge ditches along the residential area, which erode the surrounding roads to different degrees and seriously damage the surrounding vegetation. Mountain restoration, garden construction, ecological restoration and landscape improvement of flood discharge ditches are carried out accordingly to protect biodiversity and ecological environment, thus achieving a huge change from abandoned mines and barren mountains to vibrant and lush areas. The ecological environment in the area has undergone a fundamental transformation.

 Mountain restoration. The excavated soil will be backfilled to the mountain body and mining pits in combination with the construction of surrounding buildings to restore the exposed mountains. Six broken mountains with an area exceeding 300,000 ㎡ have been restored.

Garden construction. Great importance is attached to the protection of the ecological environment of the mountain while the mountain is restored. More than RMB 50 million has been invested in the implementation of the landscape upgrade project in Aozi Mountain and Quanzi areas, thus significantly enhancing the overall image of the southern region of Jinan, and the garden has been endowed with the use function, 8.4 kilometers of pedestrian road, 4.6 kilometers of cycling road and 10 kilometers of mountaineering road are also constructed. The pedestrians for climbing mountain are made of gravels in the mountain, locally available materials, thus reusing waste materials. In the construction process, we abandoned the use of mechanical equipment of our own accord but used primitive transportation tools like mules to transport building materials for the purpose of the reduction in secondary damage to the mountain. In addition, in important node areas of activity, convenient entertainment venues such as children’s playground, elderly fitness and leisure activities are also built.

Ecological restoration. In the development process, we always adhere to the concept of green development, emphasize the protection of biodiversity and continuously carry out tree-planting activities. At present, we have planted over 40 species and 100,000 trees, with a green area of over 1.6 million ㎡. Besides, a large reclaimed water station with a daily capacity of 10,000 m3 is built for the community of ELITE CITY to not only irrigate all the green area with reclaimed water but also meet the needs of landscape irrigation and garage flushing in the community residential area.

 Landscape belt of flood discharge ditches. In combination with the concept of “low-carbon materials, clean energy, resource recycling and environmental awareness”, we restore and enhance 9 landscape belts of flood drainage ditches, covering an area of over 150,000 ㎡ and a length of over 4,750 m. Mountain reservoirs and fish-scale pits for afforestation on the top of the mountain are built, with intercepting ditches constructed along the mountaineering road, to enhance the conservation function of “infiltration, stagnation and storage” of rainwater, thus the project has become a demonstration park of sponge city.

Project significance: Nine major parks, namely, Lingxiu Park, Quanzi Mountain Park, Yuanxiang Sports Park, ELITE CITY Forest Park, Hongyegu Park, Aozi Mountain Park, ELITE CITY Sports Park, Wanghualou Mountain Park and Huoli Park, have been built presently by relying on Quanzi Mountain, Aozi Mountain, Wanghualou Mountain and flood discharge ditches. The community ecosystem of “three mountains and nine parks” with a total green area of 1,610,100 ㎡, which is known as the “back garden of Jinan”, has been formed to create a healthy air environment. In the meantime, the fitness footpath of more than 30 kilometers and the outdoor fitness venue of more than 23,000 ㎡ are constructed to provide rich fitness and entertainment space for the residents in the community. They make the project awarded the titles of “National First and Largest WELL Community Operation Gold Certification” and “Global Green Model Community”.

    Enlarging fitness space and upgrading humanistic care.

    In the project was constructed not only a landscape ecosystem of more than 1.6 million ㎡ of “three mountains and nine parks” but also fitness footpath of more than 30 kilometers and outdoor fitness venues of 23,000 ㎡ in combination with the mountains and flood discharge ditches to provide larger fitness and entertainment spaces for the surrounding communities and enhance the cultural atmosphere of communities. Owners spontaneously organize over 1,000 outdoor activities every year, such as mountain day, Taijiquan exercises, tree planting and community marathons (including more than 1,200 indoor activities). Such activities not only create a comfortable and pleasant atmosphere in the ELITE CITY itself but also beautify the street scenery in the area. Therefore, such activities as an important component of urban landscape contribute to the creation of high-quality urban quality and beautiful scenery.

     Increasing green area and creating a healthy microclimate

    First, the green coverage rate of the community reaches over 70%, with a per capita green area of 20 m2, which is more than 7 times higher than the standard requirements. The negative oxygen ion content reaches 10,000/cm3, and the community is known as a "WELL Community in a forest park". Second, plant species, including broad-leaved plants are reasonably arranged to enhance their carbon sequestration capacity, and reduce carbon dioxide emission by over 23,000 tons annually; and third, improve the surrounding environment and the surrounding microclimate of the community to create a healthy air quality.

    Improve ecological environment and ensure biodiversity

    After the planting soil is backfilled in the cliff areas of Quanzi Mountain, Wanghualou Mountain and Aozi Mountain, native plant with strong soil fixation ability, such as cotinus coggygria, flowering peach, purple-leaf plum, sophora japonica var golden, cherry blossom and black locust, are used to ensure the stability of the soil slope while increasing the richness of mountain greening; and more than 40 species and 100,000 water resistant plants such as metasequoia are planted around the flood discharge ditch. In addition, wooden bird nests are arranged on both sides of parks and roads to attract bird for habitation, and pigeon squares are constructed to effectively enrich biodiversity.

    Rainwater and sewage recycling to save water resources

    First, the construction of sponge city. Based on the natural resource conditions of the project, build a mountain water reservoir, and a greening fish-scale pit on the mountaintop, and build a soil covering building and sponge demonstration base near the mountain to achieve the goal of collecting and reusing mountain rainwater, infiltrating rainwater, and reducing runoff; and the conservation function of "infiltration, stagnation and storage" of rainwater is comprehensively enhanced. The flood discharge ditch of the community has opened the valley hydrological corridor with three mountains to enable the community to become a demonstration park of sponge city. Second, recycling of reclaimed water. Construct a large-scale community reclaimed water station with an actuat daily capacity of 10,000 m3 to achieve 100% reclaimed water irrigation for green areas, and the reclaimed water can meet the needs of landscape irrigation and garage flushing in residential areas of the community.

    Continuously improve the environment to attract residents to purchase properties

    Continuously optimize and improve ecological infrastructure construction to gather popularity for local governments and increase taxes, bring economic and social benefits to the investment and construction party, seek greater development space for operators, and bring more improvement to the living environment quality and appreciation space for owners. Since 2004, the project has become from a barren land to a community of over 110,000 people, and high-quality ecological environment is one of the important factors for residents to settle down. Combined with the construction of commercial and other supporting facilities, it directly provides over 15,000 job opportunities to drive 35,000 people in the surrounding areas. Shandong Genfu Company has ranked first in the Shizhong District of Jinan City in terms of tax payment amount for many years.

    Provide outdoor fitness space and advocate a healthy lifestyle.

    Relying on the advantages of the mountain, build a 30 km of fitness footpath around the mountain and a 23,000 m2 of outdoor fitness venue, equipped with a football court and basketball court, an over 5,000 m2 of elderly activity space and an over 6,400 m2 of children's activity space.

     Increase the green area and create a healthy microenvironment.

    First, the green coverage rate of the community reaches over 70%, with a per capita green area of 20 m2, which is more than 7 times higher than the standard requirements. The negative oxygen ion content reaches 10,000/cm3, the surrounding environment and the surrounding microclimate of the community can be improved to create a healthy air quality. The trees and vegetation in mountain parks can absorb a large amount of carbon dioxide and other air pollutants, including ozone, sulfides, and carbon monoxide. Second, trees and vegetation can reduce the concentration of particulate matter and pollutants in the air, improve air quality, lower urban temperatures, provide cool shade, and regulate air humidity. Third, a high-quality living environment has a very positive impact on urban vision and noise control.

    Enhance the cultural atmosphere of community

    Based on the unique space supporting facilities, create the "Fan Community" brand, set up 28 owner interest clubs, held over 1,200 events annually, with nearly 30,000 owners participated. In addition, a Quancheng Study has been built in the forest park, with a collection of over 10,000 books, and it is a "spiritual paradise" for book enthusiasts to promote the upgrading of community service and cultural facilities.

     Biological science popularization base

    The ecosystem of "three mountains and nine parks" is rich in flora and fauna to become an educational base for schools in the community to organize outdoor activities and popularize biodiversity.

     Build green and WELL Community image

    The per capita green area is 20 m2 and is more than 7 times higher than the standard requirements. The negative oxygen ion content reaches 10,000/cm3, the surrounding environment and the surrounding microclimate of the community can be improved to create a healthy air quality. At the same time, the outdoor fitness and entertainment space conveys a healthy lifestyle to help the ELITE CITY community win the titles of "WELL Community Gold Level Operation Certification" and "Global Green Model Community".

    Use local materials to reduce transportation carbon emission

    Backfill the excavated earthwork of surrounding buildings into the mountain mine, use local materials to turn waste into treasure. This not only reduces waste caused by the outward transportation of earthwork, but also restores the exposed mountains. A total of 6 broken mountains with an area of over 300,000 ㎡ has been restored.

    Protect the environment to reduce secondary damage

    During the construction process of pedestrian mountain climbing footpath, we proactively abandoned the use of mechanical equipment and used primitive transportation tools such as mules to transport building materials so as to reduce secondary damage to the mountain.

     Improve ecological environment and enhance biodiversity

    After the planting soil is backfilled in the cliff areas of Quanzi Mountain, Wanghualou Mountain and Aozi Mountain, native plant with strong soil fixation ability, such as cotinus coggygria, flowering peach, purple-leaf plum, sophora japonica var golden, cherry blossom and black locust, are used to ensure the stability of the soil slope while increasing the richness of mountain greening; and more than 40 species and 100,000 water resistant plants such as metasequoia are planted around the flood discharge ditch. In addition, wooden bird nests are arranged on both sides of parks and roads to attract bird for habitation, and pigeon squares are constructed to effectively enrich biodiversity.

    Combined with the condition of the mountain to be restored by the project, water and soil erosion will be reduced by building mountain reservoirs and green fish scale pits on the top of the mountain, and intercepting ditches will be set up along the mountain trails, and construction technologies such as permeable pavement, rainwater collection, sunken green spaces, and rain gardens will be implemented to enhance rainwater. The conservation function of "seepage, stagnation, and storage" reduces water and soil erosion, and the total annual runoff control rate reaches more than 75%, reduces the occurrence of debris flow disasters, and improves the adaptability of surrounding areas to natural disasters and the resilience of mountains. The restored mountain is more solid and stable, preventing debris flow from flowing into surrounding houses, reducing the scope and damage of disasters, and thus improving resilience after natural disasters. The flood discharge ditch can control mountain runoff, reduce the scale of debris flow, reduce the damage of debris flow to the surrounding environment, improve the ability to resist natural disasters, and make the mountain more resilient. In addition, mountain restoration increases the diversity and strength of ecosystems to increase resilience to natural disasters. The restored mountain is more beautiful and the environment is more beautiful. It also provides a good ecological environment for local residents and tourists, promotes the development of social economy and improves the living environment of local people.
