設計理念 - 節目概念發展

我的目標是使用河畔原有的動物和土壤，發展休閒與娛樂於一身的社區農圃，成為有農地的動植物公園。同時亦會使用水生動植物改善水質，提供一個親親大自然的公共空間給市民享用。

設計宗旨是，利用動植物改善水質和美化環境，為居民提供環保、舒適的休閒與娛樂空間。設計有三項目標：

1. 保留羊群 - 用羊糞代替化學肥料發展社區農圃
2. 增加生物過濾系統 - 用動植物具天然濾水的特徵減輕排水系統的壓力
3. 減少非透水鋪地 - 用環保物料、沙石或原生草坪代替石屎地，加快雨水滲透地下

先前分析了梧桐河當地的強弱危機，參考了國內類似的案例分析，亦了解到香港公共機構官方制定的節水指南後，小總結提及過的設計策略：

1. 保留沿河空地
2. 保留當地的農田
3. 保留具有特色的牧羊
4. 保留當地太陽能街燈
5. 增設適合影相的打卡熱點
6. 拆除棕地上露天停車場的混凝土
7. 增設回收羊糞的系統
8. 砸掉公園範圍內的防洪硬岸
9. 採用百分之百的可下滲覆蓋
10. 廣植適應於季節性洪澇的鄉土植被
11. 利用富有鄉野氣息的多年生觀賞草造景
12. 是翻新或安裝節水裝置
13. 監察水錶用水量
14. 選擇節水灌溉系統
15. 安裝雨水收集及洗盥污水循環系統

我決定把先前總結的設計策略拼湊在一起。這是我自創的設計公式：A+B+C=D，A是特色，B是位置，C是技術，D是綜合設計。如此一來，就得出具有當地特色和綠色建築的設計方向：

1. 牧羊+農田+安裝雨水收集及洗盥污水循環系統= 滴灌農田可下滲覆蓋
2. 太陽能街燈+沿河空地+節水灌溉系統=公眾監察水錶
3. 棕地混凝土+防洪硬岸+植被+觀賞草=打卡熱點

這樣子，就得出三個設計重點。第一畫面在我腦海中，是六十隻羊在田野間上吃草和跳動，田野上出現了一個稻草人在灌溉，稻草人其實就是節水灌溉系統的箱子。而田野長了不同顏色的花，另外有些果樹，花鳥蟲魚的感覺。第二個畫面在我腦海中，是一座座在河畔的太陽能街燈，這些燈下有水錶箱。第三個畫面我腦海中，是打碎了的棕地混凝土，這就好像港珠澳橋隨機放置的巨大石躉，上面有鳥在停留，也依附一些水生植物。

我希望香港的河畔公園能給人一種自由、和諧的感覺。草可以踩、沙可以玩、球可以踢、狗可以跑、風箏可以放，棉花糖可以擺檔。

設計

永續農業設施

粉嶺北中央公園是一個獨一無二、自給自足、結合社區農圃於康樂、教育和自然生態項目的河畔公園。當中開設實驗農場，在社區中推行「羊蟲魚菜共生」系統。

位於上水梧桐河

粉嶺北中央公園選址在香港最北面的新發展區，目的是在保留昔日的農田的景觀，以及利用天然過濾系統淨化河畔水質。透過公園的鄉土景觀，把人與山河連接。

自給自足

使用河畔原有的天然資源改善環境：
低碳生活 - 透過擴闊和美化河濱的單車徑和行人徑，鼓勵市民外出運動，減少碳足跡。
生態浮田 - 透過牡蠣殼、菌類、水生植物、田蚌的互相配合，減少河水污垢，改善水質。
綿羊公園 - 透過蚯蚓分解綿羊的排泄物堆肥，利用廢水代替化學肥料，教育市民農務知識。

社區

粉嶺北中央公園利用社區農圃的新鮮食物，將居民們緊密聯繫在一起，鼓勵市民踏入公共空間一同調理農務，打破城市中人與人之間的隔閡。同時亦可以為區內市民提供新鮮食物。

園境建築設計

發展與保育的平衡點
交叉平行線的設計概念源自對發展與保育兩者之間平衡的展望。由以往兩條平行線，到現代的相交點，代表著智慧城市的進步。此外，利用河畔天然資源，發展怡人的低碳生活空間。

園林

配合新界北區綠化總綱圖的主題「錦繡山河」，利用色彩鮮艷奪目的植物品種營造歡迎的感覺。另外亦會廣植水生植物，以淨化水源。希望廣闊的園景區配以各種富有鄉野氣息的多年生本地植物品種和流動的水體，旨在喧鬧的城市中營造出寧靜的山河風光。

環保物料

節能玻璃 - 設施外牆主要採用具高熱效的玻璃，令室內更温暖明亮。
環保塑木 - 設施採用易於保養及含回收物料所製造的環保塑木代替天然木。
混凝土磚塊 - 設施的車道鋪設含有再造物料的環保混凝土磚塊。
寮屋物料 - 回收舊寮屋的鐵皮、木板，用於製作公園內的園藝工程和傢具。

羊糞 + 蚯蚓 = 肥料
肥料 + 農田 = 農作物
農作物 + 人 = 金錢

Design Concept - Program Concept Development

My goal is to use the original animals and soils on the riverside to develop a community farmhouse that combines leisure and entertainment, and become an animal and plant park with farmland. At the same time, water and plants will be used to improve water quality, and a public space that is intimate with nature will be provided to the public.

The design aim is to use animals and plants to improve water quality and beautify the environment, providing residents with environmentally friendly and comfortable leisure and entertainment space. The design has three goals:

Preserving the flock - using farm manure instead of chemical fertilizer to develop community farms
Increased biological filtration system - uses the characteristics of natural water filtration of plants and animals to reduce the pressure on the drainage system
Reduce impervious paving - replace environmentally-friendly materials, sand or native turf, and accelerate the penetration of rainwater into the ground

Previously analyzed the local strength and weakness crisis of the Indus River, with reference to similar case studies in China, and also learned about the design strategies mentioned in the small summary after the official water conservation guidelines developed by Hong Kong public institutions:

Keep the river along with the open space
Keep local farmland
Keep the characteristic shepherd
Keep local solar street lights
Add a punching hot spot suitable for the image
Demolition of concrete in the open-air parking lot on brownfield
Add a system for recycling sheep manure
Get rid of the flood-proof hard shore within the park
100% invasive coverage
Widely planted to adapt to seasonal flooding of native vegetation
Use the perennial ornamental grass landscape with a rich rural flavour
Is to renovate or install a water saving device
Monitor water consumption by water meters
Choosing a water-saving irrigation system
Installation of rainwater collection and washing wastewater recycling system

I decided to piece together the design strategies I summarized earlier. This is my own design formula: A+B+C=D, A is the feature, B is the position, C is the technology, and D is the comprehensive design. In this way, the design direction with local characteristics and green buildings is obtained:

Shepherd + farmland + installation rainwater collection and washing wastewater circulation system = drip irrigation farmland can be infiltrated
Solar Street Light + Riverside + Water Saving Irrigation System = Public Monitoring Water Meter
Brown concrete + flood control hard shore + vegetation + ornamental grass = punch hotspot

In this way, three design priorities are reached. The first picture is in my mind. Sixty sheep graze and beat in the fields. A scarecrow is irrigating in the field. The scarecrow is actually a box for water-saving irrigation systems. The fields grow flowers of different colours, and some fruit trees, flowers, birds and fish feel. The second picture is in my mind. It is a solar street light on the riverside. There are water meters under these lights. The third picture in my mind is the broken brown concrete. This is like the huge stone sarcophagus randomly placed on the Hong Kong-Zhuhai-Macau Bridge. There are birds on it and some aquatic plants.

I hope that the riverside park in Hong Kong will give people a feeling of freedom and harmony. The grass can be stepped on, the sand can be played, the ball can be kicked, the dog can run, the kite can be placed, and the marshmallow can be placed.

Sustainable agricultural facilities
Fanling North Central Park is a unique, self-sufficient, riverside park that combines community farming in recreational, educational and natural ecological projects. An experimental farm was set up in the community to promote the "community of sheep, fish and vegetables" in the community.

Located in Wutong River, Sheung Shui
Fanling North Central Park is located in the new development zone in the northernmost part of Hong Kong. The purpose is to preserve the landscape of the former farmland and to use the natural filtration system to purify the riverside water quality. Connect people to the mountains and rivers through the rural landscape of the park.

Self-sufficiency
Use the original natural resources of the river to improve the environment:
low-carbon life - encourage people to go out and reduce their carbon footprint by widening and beautifying the cycling and footpaths on the riverside.
Ecological floating field - Reduces river water pollution and improves water quality through the cooperation of oyster shells, fungi, aquatic plants and field rafts.
Sheep Park - Through the decomposition of sheep's excrement compost, using wastewater instead of chemical fertilizers to educate citizens about farming knowledge.

community
Fanling North Central Park uses the fresh food of the community farms to closely connect the residents, encourage the citizens to step into the public space to adjust the farming, and break the gap between people in the city. Fresh food can also be provided to the residents of the district.

Landscape architecture design
The balance between development and conservation The
the design concept of cross-parallel lines stems from a vision of the balance between development and conservation. From the past two parallel lines to the modern intersection, it represents the progress of the smart city. In addition, the use of natural resources along the river to develop a pleasant low-carbon living space.

garden
In line with the theme of the New Territories North District Greening Master Plan, "Jinxiu Shanhe", the use of colourful and eye-catching plant varieties creates a welcome feeling. In addition, aquatic plants will be planted to purify water. It is hoped that the vast landscaped area will be complemented by a variety of perennial native plant species and flowing water bodies that are rich in rural flavours, creating a tranquil landscape of mountains and rivers in the noisy city.

Environmentally friendly materials
Energy-saving glass - The exterior of the facility is mainly made of glass with high heat efficiency, making the interior warmer and brighter.
Environmentally Friendly Plastic Wood - The facility replaces natural wood with environmentally friendly plastic wood that is easy to maintain and contains recycled materials.
Concrete Bricks - The driveway of the facility is paved with environmentally friendly concrete blocks containing recycled materials.
Squatter Materials - Recycling of iron and wood from old squatters for horticultural works and furniture in the park.

Design element
Multi-functional facilities
Turn waste into energy - worm fish and sheep symbiosis system
Leisure activities - cycle track
Education - Community Farm


Turn waste into energy
Sheep worm symbiosis system:
aquatic plants + oyster shells + gravel + ridges = purified river water
purified river water + soil = grass
sheep feed + sheep = sheep
manure sheep manure + earthworm = fertilizer
fertilizer + farmland =
crops + people = money
