【生物碳封存|植被生態系統係點樣固碳?】
大家平時行山見到大嶼山咁多綠色植物,有無諗過佢哋其實係幫地球「降溫」嘅大功臣?呢個過程就係「生物碳封存」,等我哋簡單拆解下呢個「地下金庫」點樣運作:
1️⃣吸入去:植物透過光合作用,吸收大氣中嘅二氧化碳,轉化成有機碳,一部分用嚟生長、儲喺樹葉、樹幹同埋根入面,另一部分會輸送去土壤。
2️⃣泵入土:植物死後嘅枯枝落葉,同埋生長過程中釋放嘅「根系分泌物」,都會將碳元素帶去地下土壤。
3️⃣鎖死佢:土壤入面嘅微生物會將呢啲碳轉化成好難分解嘅穩定有機物,長期儲存喺泥土中。
呢個過程唔單止幫大嶼山嘅森林「鎖住碳」,仲可以減少大氣中嘅溫室氣體,幫地球降溫,所以我哋先要好好守護呢片綠地呀🌲~

【Biological Carbon Sequestration | How do vegetation ecosystems capture carbon?】
When you’re hiking and enjoying the lush greenery of Lantau, have you ever wondered how these plants actually help "cool down" the Earth? This process is known as "Biological Carbon Sequestration." Let’s break down how this "underground vault" works:
1️⃣ Absorption: Through photosynthesis, plants absorb carbon dioxide from the atmosphere and convert it into organic carbon. Part of this is used for growth—stored in leaves, trunks, and roots—while the rest is transported into the soil.
2️⃣ Pumping into the soil: Dead leaves and branches (litterfall), along with "root exudates" released during growth, carry carbon elements deep into the soil.
3️⃣ Locking it away: With the help of soil microbes, this carbon is transformed into stable organic matter that is difficult to decompose, allowing it to be stored in the soil for the long term.
This process doesn't just "lock carbon" within Lantau’s forests; it also reduces greenhouse gases in the atmosphere to help mitigate global warming. This is why we must protect our green spaces!🌲
