※ 引述《assxass (包子)》之銘言:
: 而新樹附加了固碳功能 重新的景觀規劃 有何不好
您不斷強調樹木的固碳作用,數次忽視它降溫、淨化空氣、維護生物多樣性……等效果,
即使其他網友不斷解釋都市裡行道樹最重要之處不在「固碳」。
好吧,那麼我們就來談固碳:

(縮: http://goo.gl/eEXthc )
http://www.nature.com/nature/journal/v507/n7490/full/nature12914.html
這是Nature 2014年論文,
主張老樹固碳效果優於新樹。
以前研究以為老樹固碳能力低,
是因為以前多是研究整片樹木年紀相近的森林,而不是研究 individual trees。
整片森林牽涉到的機制太多,
既然我們現在談的是都市行道樹,根本不成森林,
那麼把眼光著重在 individual trees 的固碳能力,也是很合理的吧?
老樹在固碳能力上勝出——至少這篇 Nature 和數篇引用它的論文都這麼說。
那麼在科學界尚未有定論之前,
您可同意先別急著把老樹砍掉?
