中研院研究指出樹冠減少相當於1.3萬棵樹,市府回應與開發及中央建設有關,遭議員質疑政績灌水
中研院研究員沈聖峰利用衛星影像分析,發現台北市兩年內樹冠面積淨減少13.7公頃,約等於1.3萬棵樹消失。台北市公園處歸因於私人土地與中央建設開發,遭沈伯洋與議員洪婉臻批評市府推卸責任且政績數據灌水。

中研院研究員沈聖峰利用歐洲太空總署衛星影像,計算出台北市街樹冠面積兩年內淨減少13.7公頃。市府公園處則強調已新增超過1.3萬棵樹,並將減少歸因於私人開發與中央建設。
台北市民近期陸續發現路樹減少,中央研究院生物多樣性研究中心研究員沈聖峰指出,衛星影像計算兩年來台北市樹冠面積淨減少13.7公頃,相當於1萬3000棵樹的樹冠從市區消失;公園處認為與私人土地、台大校地開發、國道交流道綠蔭減少等含中央建設有關。民進黨籍台北市長參選人沈伯洋說,如果又在說中央,就是沒有打算要回應問題,呼籲市府盡快說明清楚。市議員洪婉臻批評,蔣市府樹冠減少就怪中央、怪私地、怪台大;要算樹木增加,就公、私地一起算變成蔣萬安的政績,只能說「樹不會騙人,蔣萬安會」。
沈聖峰臉書發文提到,團隊用歐洲太空總署的衛星影像進行系統性計算,將每年同一季節的多幅影像合成,判讀出樹冠面積,結果顯示市街內部的樹冠面積從2024年的628公頃降至今年的615公頃,兩年淨減少13.7公頃,而且第二年減少幅度比第一年更大,若以每棵樹冠約10平方公尺換算,相當於1萬3000多棵樹的樹冠從市區消失。但也提醒,衛星看到的是地表覆蓋的變化,無法分辨是砍除、移植、修剪或是颱風所致。
公園處經比對相關資料後表示,樹冠面積減少較大的地點成因,除了私人土地開發外,還有台大校地開發、國道交流道綠蔭減少等包含中央建設的案例,顯非市府任意砍樹造成,強調市府近兩年已新增超過1萬3000棵樹,明年市區將再增3555棵,願與沈聖峰團隊交流,一同推動台北綠色基盤建設。
沈伯洋出席兒少倡議活動說,「如果又在回答中央的話,真的就是沒有打算要回應問題。」也訝異樹木議題討論應有一、兩個月,如果有些是中央、有些是私人或是生病,那到底佔比是多少?為何到現在都還沒有辦法對外清楚說明?「有點誇張!」
洪婉臻說,市府所稱1萬3225棵,公園處只有1739棵;大地處4842棵,其中包括劍南蝶園、內雙溪自然中心等林地,甚至還有富德公墓。市府把風景區、公墓樹木算進來,再告訴市民行道樹只增不減,根本混淆視聽,「最離譜的是建管處上報的6644棵,這是核發建造執照時,建築師登載的植栽數量。這也算蔣萬安市府種的?」
洪婉臻批評,蔣市府樹木減少時,就推中央、私地、遭遇天災;要算新種植數量,私人建案又變成市府政績;私地砍樹不歸市府管,私地種樹又拿來湊政績,「蔣萬安吃相難看!」市府若堅持近兩年新增1萬3000多棵樹,就應完整公布種植地點、實際種下或還只是建照上的預計植栽,衛星數據看到的就是樹冠減少,不要硬凹。

Thai Prime Minister Anutin ended his overseas trip ahead of schedule and returned to the country to direct the flood relief work in Bangkok and surrounding areas.
