彩鷸在過去是屬於農村常見的水鳥，唯因棲地破壞、農事活動及人為獵捕，族群數量快速減少。本研究聚焦在彩鷸棲地結構與農地景觀間之關係，取樣嘉義縣大林鎮、民雄鄉之農區，調查彩鷸族群數量及其分佈與景觀結構之關聯性。透過現地觀察及衛星航照圖，佐以景觀生態學常用之景觀指標，加以評估分析。研究結果發現，彩鷸分佈之密度與景觀綴塊類型較多、景觀多樣性及均勻度均較高等特性有關。此外，農區是否使用慣行農法或自然農法並非是影響彩鷸棲息之主要因素。然若景觀過於單一化，例如整片的水田，則非屬於彩鷸優良之棲地結構。故以里山倡議的概念來說，對彩鷸棲地結構之規劃設計，不宜僅以視覺美感為考量所獲致之單一、整齊之景觀；反之，建議應以多樣化、均勻化景觀綴塊之方式操作。 In the past, the waterbirds of the greater painted snipe are common in rural, specifically in paddy field; however, the population is dramatically decline owing to the destroyed of their habitat, farming activities and associated human disturbances. This study focused on the relationship between the habitat structure of the greater painted snip and farmland landscape. In addition to observing the painted snipe in field, the satellite imageries were applied to evaluate the landscape indices, to quantifing the landscape structure of the painted snip habitat. The study results showed that the population density of the painted snipe was associated with the more patches types of landscape, or higher landscape diversity and landscape evenness. However, whether using conventional/ecological agricuture or not, they are not the factors to influence the distribution of the painted snipe. If the landscape is too simple, such as the whole piece of paddy fields, it is not suitable habitat structure for the painted snip. As for the concept of satoyama initiatives, the optimal designation of landscape could not follow the simple landscape or only pursue the visual beauty, but suggest landscape diversity and evenness of patches.
