本研究以景觀建築師的角度探討鳥類與景觀元素間的相互關係。主要以鳥類的豐度、均度及岐異度作為鳥類生態與不同景觀元素相關性的檢測指標。 研究以淡水河口鳥類的種類驗證「影響鳥類族群的生態景觀元素理論」為研究調查目的。報告中，溼地、稻田、農地及建物等之面積大小為獨立變數；鳥類的豐富性、均質性及多樣性則為因變數。 研究發現農地面積大小與鳥類數量成反比；而河川面積大小則與鳥類數量成正比。農地與鳥類的均度及歧異度兩者皆相關。由航照圖的觀測則可發現，道路的開發與鳥類總數成反比；森林則與鳥類的豐度成正比；空地與寫類的豐度成反比；溼地對鳥類岐異度呈正相關；農地則增加了陸鳥出現的機會，也增加了鳥類的均度。 五千分之一比例的航照圖提供了詳細的土地使用狀況，依此資訊可推測鳥類種類的分布情形，進一步了解鳥類豐度及均度的變化。而都市及非都市土地的不同土地利用模式則可提供進一步的研究。臺灣地區的非都市土地利用為景觀生態之關鍵性地區，需要長時期收集更多資訊持續深入研究，才能了解更多相關訊息並提供未來景觀規劃及設計之使用。

The purpose of this survey study is to test the theory of landscape element of landscape ecology that relates the landscape elements to bird communities for bird species at the estuary of Danghsui River in Taiwan. The independent variables such as the areas of wetland, rice paddy, small woods, farm, building, etc., were defined generally as landscape elements. The dependent variables were defined generally as birds’ rich index, which includes the richness, evenness, and the diversity of bird’s communities. This study find Aero-photography map (1/5000) provides detailed land uses, which can trace out the scatters of patches and explain more variances of bird’s diversity, richness and evenness. Further studies related to the urban and the rural areas are needed due to the different land use patterns. Especially in the rural areas of Taiwan, the information of landscape ecological is in a critical position.
