北高雄城區綠色基礎設施系統之建構與發展策略

Abstract

北高雄基於近年來交通發展與都心轉移的契機，讓既有建成與生態環境再次受到經濟與社會變動所產生的衝擊。而北高雄現前的都市脈絡(生態、人文、建成環境…等)到底如何，可否透過策略方案融合現有環境特質發展出一種適於永續生存的環境空間，是目前的重要課題。 綠色基礎設施是近年來基於土地資源保育和管理、對抗蔓延造成的環境、社會與經濟衝擊，而發展出來的一種綜合性的空間規畫思維，其概念是以節點(hubs)、鏈結(link)、與基地(site)的系統連結來建構可持續發展的地景生態格局；具體而言，綠色基礎設施是連結的綠色空間網絡，其範圍包括了自然區域及其中的物件、公共與私人的保育土地、有保育價值的資源與其他類型的開放空間；如果能夠維繫、管理與規劃這些綠色空間資源，將可為人們提供和創造許多層面的效益。 北高雄目前因為其位於都市開發邊緣的關係，仍存留著部分舊時的水圳遺跡(曹公新圳)，而綠地的狀態則是零散，且隨著縣市的分界有著不同的面積以及分布狀態。有鑑於此，希望透過綠色基礎設施的空間規劃思維，保存文史資產與自然生態資源，創造更可居的都市環境。 因此，本研究將深入探討其綠色基礎設施的學理概念為何？剖析實踐綠色基礎設施之規劃概念、方法和推動執行的機制設計，以北高雄地區為案例，提出具體的空間規劃手法，落實地方利益關係網絡，探討如何進行城市地景生態的改造、再生和營造策略。

Due to the building of Metropolitan Traffic System and the city’s development, north Kaohsiung’s built environment and ecosystem were economically and socially challenged. So it is important we must understand the urban context (ecologically, socially, and physically) and then develop a strategy that most fit it and both sustainable. Green infrastructure was a kind of spatial planning concept both deal with land resources’ preservation, management and against sprawl phenomenon. It builds landscape structure with hubs, links and sites. Physically, green infrastructure is connected green space network. It involves natural areas and the element within it, public and private preserves, other open land and worthily preserved resources. If people would allow to plan and management these green space resources well, it could provide people with a lot of benefits. North Kaohsiung was not heavily developed, so it keeps some of the Tsaogong ditch and canals. But green lands here are scattered in different city region. This research hopes to preserve historical and ecological resources with green infrastructure’s concept and spatial planning to make a livable urban space. Thus, this research will devote on how the green infrastructure’s mechanism functions and works. And then puts it into the real context of north Kaohsiung, develop a plausible strategy which benefits the city, ecosystem and community.
