落葉喬木樹葉存在期短，一年內葉子便會全數脫落，全部老葉脫落后便進入休眠時期。一般絕大多數的落葉樹都處于溫帶氣候條件下，夏天繁茂、冬天落葉，少數樹種可以帶著枯葉而越冬，今天小編就為大家介紹下園林綠化中常見的30種落葉喬木。 Deciduous trees leaves existence period short, leaves will fall out all within a year, after all the old leaves fall off into a period of dormancy. Generally most deciduous trees in temperate climates, summer and winter leaves, a few species can take the dead leaves and wintering, small make up today is to introduce the common in the botanical garden afforestation under 30 species of deciduous trees. 1.核桃，胡桃科胡桃屬 1.
