為了解決oak tree leaves 的問題,作者Gianferrari, Maria 這樣論述:
讓我們向樹學習,成為更好的人! 在我們生活環境中,樹是一個平凡而重要的存在。但你有沒有發現,其實我們像極了樹。從脊椎、軀幹,到皮膚、表皮。心臟給予我們力量,幫助我們生存,像心材一樣。我們也從水和太陽中吸收能量。 更神奇的是,樹也像人類一樣具有社會性。它們會「交談」、傳播資訊,也會分享養分和資源。它們會互相保護、彼此照顧。樹的美以及歷經滄桑的優雅都教人讚嘆。 本書作者是從小愛樹的瑪莉亞.姜弗勒里,以她對樹的研究,創作了這篇優雅的文字,告訴我們從樹的身上,我們能學到更多。如果我們待人處事都像森林中的樹,懂得保護彼此,不分族群、共享資源,這個世界一定會變得更加美好! 本
書的插圖是由獲大獎肯定、畫風深受喜愛的繪者費里希妲.薩拉創作,奔放的筆觸、各種不同角度的構圖,創造出這本美麗且詩意的作品,歌頌大自然中最偉大的創造物。 藉由這本繪本,不僅讓讀者從人們身上看到樹的美與雄偉,同時也帶著我們,向樹學習,一起成為更好的人。 * 中文書介摘錄自《成為一棵樹》,聯經出版 A lyrical, gorgeously illustrated look at the majesty of trees—and what humans can learn from them Stand tall. Stretch your branches to the
sun. Be a tree! We are all like trees: our spines, trunks; our skin, bark; our hearts giving us strength and support, like heartwood. We are fueled by air and sun. And, like humans, trees are social. They “talk” to spread information; they share food and resources. They shelter and take car
e of one another. They are stronger together. In this gorgeous and poetic celebration of one of nature’s greatest creations, acclaimed author Maria Gianferrari and illustrator Felicita Sala both compare us to the beauty and majesty of trees—and gently share the ways in which trees can inspire us
to be better people.
都市公園空氣品質淨化效益之測定與模式驗證:以臺中市文心森林公園為例
為了解決oak tree leaves 的問題,作者林晉陞 這樣論述:
都市公園為都市環境中不可或缺的重要角色,可為都市提供環境綠美化、休閒遊憩場域及降低空氣汙染危害等生態系服務。其中在空氣淨化方面,臺灣較缺乏本土公園的相關實測數據,故本研究以臺中市文心森林公園做為試驗樣區,分別以:(一) 移動式濃度監測確立公園減緩大氣PM濃度的具體效益;(二) 由樟樹 (Cinnamomum camphora) 葉表面截留PM功能探討乾沉降效應,及應用被動式監測方式確立公園內外汙染狀況;(三) 針對大氣PM2.5吸附、葉內吸收及表土累積等重金屬或微量元素分析,確立公園整體的環境安全;(四) 針對i-Tree Eco模擬公園樹木移除PM2.5的通量予以現地實證,並以該模式量化公
園整體生態系服務的效益與經濟價值。首先透過移動式PM濃度監測結果顯示,公園內外PM2.5及PM10的濃度減緩效果,最高可分別達到20.82%及22.29%;另外,公園內部樟樹葉表面的PM乾沉降通量,相較於外部鄰近文心路處顯著下降,除了反映該路段為主要的PM來源外,也顯示公園植被可透過截留作用,增加道路源PM的乾沉降效果。另一方面,透過主動及被動式的PM成分監測,確立公園內部的多個重金屬含量普遍較外部為低,差異最高約可達3倍;同時由葉片及土壤中長時期累積的重金屬含量差異,也顯示公園內部具有更加良好的遊憩環境。最後,本研究應用i-Tree Eco 模擬估算出文心森林公園的碳儲存約217.47 t,
相當於新台幣約326,200元的價值;而每年另可獲得之生態系服務如碳吸存為25.68 t yr−1、避免逕流為464.36 m3 yr−1及汙染物移除為0.39 t yr−1等,共計可貢獻新台幣約372,490元yr−1的經濟價值。然而,i-Tree Eco針對都市樹木移除PM2.5的模擬結果,在樟樹方面不同時間下將高估3–10倍;而在10種臺灣原生樹種的比較上,模擬值普遍高估約1.3–14.8倍。由於臺灣的生物多樣性較高,同時也為都市林經營管理之目標,因此未來仍需更多本土化的研究數據,以建立完整的樹種截留移除PM之指紋資料庫。本研究透過i-Tree Eco模式及多面向的現地實測資料,為都市公
園所貢獻之多樣化的生態系服務,建立完善的基礎資料。
The Riven Tree
為了解決oak tree leaves 的問題,作者Kautz, Robby/ Walker, Deborah Knott (ILT) 這樣論述:
A young oak tree dreams of growing tall and straight and beautiful. When violence shatters her dreams, her path is hopelessly altered. Attempting to hide her imperfections, she labors to produce the most beautiful leaves. Year follows year until, one day, her strength is gone. On that day, she asks
God the questions she has been too ashamed to voice. Oak's story provides insight into the effects of trauma. While not specific to a religion or philosophy, The Riven Tree seeks to answer the heart's deepest question: "What does God think of me?" Like Oak in this story, author Robby Kautz' life was
altered by violence. Unspoken questions haunted her until a message from God brought healing. The Riven Tree shares this message with readers whose lives have been altered by trauma. Reminiscent of The Giving Tree, this illustrated book offers redemption and hope for wounded hearts. "The Riven Tree
is a masterpiece Acorn's journey mirrors so many who have endured abuse and trauma. Robby Kautz elegantly weaves her inspired tale - every word is intentional, every sentence paints a picture, and every page tells a thousand stories. My prayer is that survivors of all ages, all ethnicities, all so
cial-standings, and all religions will find hope and healing in this beautiful book." Lori Wilkerson Stewart, Author, Promises for Prodigals, and Managing Producer, Christian Broadcasting Network "The Riven Tree is a beautifully written allegorical tale that sensitively conveys the emotions and ques
tions experienced by anyone who has had their life torn by trauma. Having lived it herself, Robby Kautz is able to put to words this often unspoken and isolating journey. For those who have traveled this path, The Riven Tree will encourage you toward hope and a deep sense that you are worthy, loved,
and beautiful. As a trauma therapist, I'm delighted to have such a relatable resource to help my clients process their experience. I will be recommending it wholeheartedly " Laura Taggart, Licensed Marriage and Family Therapist, and Author, Making Love Last: Divorce-Proofing Your Young Marriage R

都市林的生態系服務:空氣汙染物的截留、生物性監測之應用及空氣品質的提升
為了解決oak tree leaves 的問題,作者蘇子豪 這樣論述:
都市林為建構韌性都市中不可或缺的重要角色,可為都市居民提供許多的生態系服務,其中都市林的淨化空氣功能已廣為人知,但其實質對於空氣品質的影響程度,在臺灣缺乏本土化的數據檢驗。本研究將傳統概念上,森林可淨化空氣的生態系服務,進一步細分為對空氣汙染物的截留、空氣汙染的生物性監測應用及空氣品質的提升效益等,三個面向進行研究:首先在空氣汙染物的截留試驗中,針對臺中市三個行政區內,五種鄉土樹種的葉表面懸浮微粒,及相關水溶性離子的乾沉降進行現地試驗,結果顯示總懸浮微粒的乾沉降通量在不同時間、區域及樹種間呈現顯著的三因子交互作用。各粒徑懸浮微粒的乾沉降通量,皆與其所處區域的大氣濃度呈現顯著正相關;然而,其乾
沉降速度則普遍與環境風速呈現弱負相關。而在樹種差異方面證實了茄苳 (Bischofia javanica) 對於硫酸鹽的截留普遍高於其他樹種。另外,由各樹種對於硫酸鹽的截留通量月變化趨勢顯示,在12月存在長程傳輸汙染的可能性。其次在空氣汙染的生物性監測應用上,主要聚焦於空汙季節中,應用葉表面截留的PM2.5及相關重金屬成分之分析,進而評估區域間的空氣汙染特性。在樹種差異上,苦楝 (Melia azedarach) 或臺灣欒樹 (Koelreuteria elegans) 的PM2.5截留能力顯著最高,而樟樹 (Cinnamomum camphora) 則最低。葉表面PM2.5在各時間、區域及樹
種的總平均乾沉降通量 (33.91 μg m−2 h−1) 與i-Tree Eco的模擬值高度相符 (31.53 μg m−2 h−1),證實此模式應用於臺灣都市林對PM2.5的截留移除計算時,在大尺度的模擬應用上具有良好的成效。此外,研究亦發現在乾沉降時間達到450 h時,葉片對於PM2.5的承載能力將會下降,因此未來在極端氣候影響而可能導致的乾季延長下,須針對此現象進行更深入的試驗。另外,應用葉表面截留之PM2.5進行大氣重金屬的成分分析,發現多個重金屬的濃度於鄰近市中心的南屯區較高,後續也透過都市大範圍的樟樹試驗,成功確立部分位點雖具有較低的PM2.5濃度,卻存在較高的重金屬危害;綜上驗
證了以都市樹木進行大氣汙染物的空間分布監測,具有良好的指標作用。最後在空氣品質的提升效益方面,主要針對臺灣北部二處植被類型與覆蓋度差異較大的都市公園,進行現地PM2.5的移動式濃度監測,並透過六種PM2.5減緩率計算方案,確立由公園外部進入內部時,可享有的空氣品質提升成效。其中,臺北植物園具有高覆蓋度的複層林結構,對PM2.5存在穩定的減緩效應;而中和四號公園則因屬開放式的公園,造成PM2.5可能快速延散或累積於公園內部。此外,在高空氣汙染事件時,臺北植物園對於PM2.5的平均及最大減緩率為6.56%及20.85%,分別為中和四號公園的2.3及1.4倍;同時,二處公園外部樹木截留的懸浮微粒中,
重金屬的濃度亦顯著高於內部。綜上結果表明都市公園不僅能夠減緩大氣PM2.5的濃度,同時公園內部PM2.5的有害重金屬濃度亦較低,驗證了公園樹木對於區域性空氣品質的提升效益。本研究透過三個面向的實驗,證實都市林除了可以截留空氣汙染物外,並可應用此功能進行空氣汙染時空資訊的生物性監測,同時也能實質提升所在區域的空氣品質。綜上成果闡明了都市林與空氣品質相關的生態系服務,並可為未來都市林的經營管理,提供實用的在地化資料。
