都市林經營效益改良之研究

都市林淨化空氣與水、美化環境、提供休憩、教育與生物棲地等，均是廣為人知的功能，而如何透過都市林之組成設計與經營策略以促進環境品質、生態功能、碳吸存與人類健康，為當今先進國家林業經營重要方針。然台灣對都市林的環境與生態效益除基礎調查外仍停留在理論與概念上，而樹種單純、物侯特性不同的溫帶地區其研究成果亦難以應用在物種豐富、終年常綠的亞熱帶。為提升台灣都市林之環境
效益與生態功能，本計畫擬針對樹種組成、生長撫育、環境特性、棲地管理及物種監測等進行整合性研究，並將各項成果藉模式模擬以提供決策者所需的資訊。
Urban forests are dynamic ecosystems that provide environmental services such as clean air and water. The function and benefits of urban forest including cool cities and save energy; improve air quality; strengthen quality of place and local economies; reduce storm water runoff; improve social connections; complement smart growth; and create walkable communities. However there was few ecological study about urban forests in Taiwan. The environmental benefits associated with the urban forest, such as carbon sequestration and air quality improvement, have a value to society. As trees often provide benefits that reduce external costs to
society (e.g., air pollution), estimates of these external costs (externality costs) should be applied to the trees. Thus, we conducted
this research for improving the management practices to enhance the benefit of urban forests in Taiwan.
