樹木與綠化

繁體中文

香港嘅樹木覆蓋主要喺郊野公園（約佔土地四成），但市區綠化同樣重要。發展局綠化、園境及樹木管理組（2010 年成立）統籌全港樹木管理；各部門（路政署、康文署、地政總署）負責各自範圍嘅樹木。 古樹名木名錄由發展局樹木辦管理，收錄直徑 1 米以上、或高度 25 米以上、或樹齡超過 100 年嘅樹木。呢啲樹木受特別保護，未經許可不得砍伐。 市區樹木面對嘅挑戰包括：生長空間有限、颱風損害、病蟲害（如褐根病）。2018 年超強颱風山竹令全港數以萬計樹木倒塌，暴露市區樹木管理嘅問題。 常見市區樹種包括細葉榕、鳳凰木、宮粉羊蹄甲、木棉、白蘭等。細葉榕係香港最常見嘅市區樹，喺舊區街道常見百年老榕。 樹木保育同城市發展經常衝突：新發展區嘅樹木保育、市區重建中嘅老樹保留，係持續嘅政策議題。發展局每年公布樹木風險管理報告。 本站只寫有官方來源嘅樹木政策同統計；個別樹木嘅位置同健康狀況以樹木辦名錄為準。

Hong Kong’s tree cover is concentrated in the country parks, but the urban forest is substantial. The Greening, Landscape and Tree Management Section of the Development Bureau (established 2010) coordinates tree management; departments including Highways, LCSD and Lands manage trees in their own areas. The Register of Old and Valuable Trees is maintained by the Tree Management Office. It records trees of 100 years or older, or of particular value, which receive special protection and may not be felled without permission. Urban trees face particular challenges: limited growing space, typhoon damage and pests such as brown root rot disease. Super Typhoon Mangkhut in 2018 felled tens of thousands of trees across the city, exposing weaknesses in urban tree management. Common street trees include Chinese banyan (Ficus microcarpa), flame of the forest and kapok. The Chinese banyan is the city’s most familiar street tree, with century-old specimens in older districts. Tree preservation often conflicts with development: retaining old trees in new development areas is a recurring policy issue. The Development Bureau publishes annual tree-risk management reports. This site records only tree policy and statistics with official sources; individual tree locations and conditions follow the Tree Register.
