| 摘要: | 都市植物為各種都市生物棲地結構與品質的關鍵因素，影響都市生物多樣性與生態服務功能。唯都市景觀生態研究通常把都市中的綠地簡化成土地利用類型中的各綠地類型或土地覆蓋中的綠覆類型，並未更詳細檢視綠地或綠覆中空間異質性與植物群落之間的關係。本研究繼前期研究利用植物調查資料將都市公園區分為四大類公園生態斑塊類型之後，擬接續以都市公園內部的綠覆微型斑塊為題，於前期已完成全區清單式植物調查的78個台北市公園，以現地調查的方式於公園內部界定各個綠覆微型斑塊範圍，同時調查微型班塊的來源、邊界類型、景觀設計之功能設定、設計手法、維管強度等潛在驅動因子。最後再利用梯度分析，將都市公園內的各個微型斑塊用其植群組成加以分類，並探討綠覆微型斑塊與潛在驅動因子之間的關係。研究課題包括：1) 台北市公園內各個綠覆微型斑塊，若依植物組成可以分成哪幾種微型斑塊類型，其植物物種組成有何異同? 2) 這些綠覆微型斑塊於四大類公園生態斑塊中的分部狀態如何? 3) 綠覆微型斑塊的來源、邊界類型、功能設定、設計手法、維管強度等潛在驅動因子中，哪些對影響微型斑塊的植物組成較重要? 4) 這些驅動綠覆微型斑塊的因子，與驅動上一層級綠地生態斑塊的因子有何異同?
Urban vegetation affect urban habitat structure and quality, and form the foundation of urban biodiversity and ecosystem services. Past research of landscape ecology in urban areas mostly use greenspace types in landuse surveys or land cover classifications to represent the different types of greenspaces, but seldom study the finer scale heterogeneity within greenspaces. Through plant community classification using onsite vegetation survey data collected over the past three years, we have successfully identified four different urban greenspace eco-types. In this study, we propose to further study the finer scale heterogeneity within greenspaces using the vegetation survey data. We propose to delineate fine-scale green-patches within greenspaces through onsite survey, compile plant survey data using fine-scale green-patches, then classify these fine-scale green patches using their plant community data. We also propose to survey and evaluate potential fine-scale green-patch plant community drivers, including micro-patch source, edge type, landscape design function, design method, and intensity of maintenance. Finally, statistical analysis will be used to find the correlation between fine-scale green-patch plant communities and potential drivers. Research questions include: 1) What types of fine-scale green-patches can be found based on plant community data? How are their plant communities different? 2) How are these fine-scale green-patches distributed among the four urban greenspace eco-types? 3) Which of the potential plant community drivers, including micro-patch source, edge type, landscape design function, design method, and intensity of maintenance, are most related to micro-patch plant communities? 4) Are the important plant community drivers different between scales? |
