摘要:	都市景觀以建築物及道路為基質、公園綠地鑲嵌其中為綠色島嶼，聯合構成人類與其他生物共同棲息的特殊環境。相關研究中指出，環境的空間特性對內部的物種有極大的影響力，因此，本研究以283個台北市公園綠地之鳥類調查資料及數位大地影像為基礎，對台北市都市公園綠地進行數化整理完成空間結構相關圖層，再利用相關性分析、樹狀分析以及路徑分析，來探討樣區內部以及樣區周邊環境兩種空間尺度的空間結構特性與鳥類群聚特性之間的相關性。本研究結果發現：1. 公園綠地內部的空間結構對鳥類之影響較大，其中以公園面積為影響鳥類群聚特性最明顯之指標，當面積小於1.65公頃時鳥類豐富度最低。 2. 喬灌木面積越大，有利於提升鳥類總密度、豐富度、多樣性，尤其對非都市陸鳥及繁殖鳥類之影響最顯著，鄰里公園喬灌木面積達60% 以上時對鳥類多樣性之提升最有幫助。 3. 水體面積能提供水鳥棲息，對非水鳥之鳥類亦有正面效益，尤其當水體面積達11.9%以上，有利於增加水鳥的豐富度。 4. 草地面積比例越高，有利於非都市陸鳥數量及種類的提升。 5. NDVI值越高鳥類豐富度越高，尤其能有效提升非都市陸鳥之鳥類豐富度。 6. 公園內之建築物面積比例越高，對非都市陸鳥及水鳥之豐富度有負面影響。因此本研究建議都市公園綠地的開發，除了應增加公園綠地之面積，並且應該重視內部空間結構之配置，多栽植喬灌木，配置方式以群植為佳，設置水體、以草地取代不透水鋪面，以增加鳥類多樣性。 Urban landscape is composed of buildings, roads, green sites and parks, and is a special environment in which mankind and other living beings live together. Previous researches have indicated that the characteristics of landscape structure have great influence on residing species. We sampled 283 green spaces and parks, and analyzed the landscape structure in and around the samples, and used Correlation Analysis, CART and Path Analysis to investigate the relationship between landscape structure and avian communities. Results show that: 1. Landscape structure inside the park have greater influence on the birds, and park area is the most important predictor of bird richness. When park area is lower than 1.65 ha, bird richness is the lowest. 2. Trees and shrubs are very important to the bird diversity of non-urban land birds and breeding birds. Bird diversity is higher when the area of trees and shrubs in neighborhood parks is more than 60%. 3. Water coverage increases the bird density and the richness of both water birds and other bird species. Increase in the percentage of water in the park increases bird diversity. 4. Increasing the percentage of grass coverage improves bird density and richness. 5. Increasing the area of trees and shrubs thus increasing NDVI can increase the species richness of non-urban land birds. 6. Buildings reduce bird richness, especially to non-urban land birds and water birds. Our results suggest that not only should the area of green spaces be increased in urban areas, but the configuration inside the parks should also be carefully considered. In order to improve bird diversity, the planner should plant more trees and shrubs, set up lakes and ponds, and replace impermeable surfaces with grasses or meadows.
