台灣客家族群有許多珍貴的民俗傳統，蘊藏著這個族群對大自然抱持的生態友善態度。然而，在現代化的衝擊下，傳統的客家族群生活型態悄悄改變，許多客家民俗也漸有散佚跡象，殊為可惜，但也可看到當代新生的客家民俗正在積極地創發傳統。客家民俗由傳統到創新，含藏於其中的「可持續性」元素可說是客家民俗一個堅強的、值得傳播的文化基因。本研究認為，若能由生態民俗觀點出發，探究客家民俗生活與環境生態的交互影響，凸顯出其中的生態意涵並積極活化相關民俗精神，一方面可提升客家文化民俗的保存價值，另一方面也可建構一條實踐環境倫理的新路徑。因此，本研究以客家信仰民俗為對象，嘗試探討傳統與當代客家民俗事象中含藏的生態思想。內容除了說明民俗與生態的關係之外，還包括探討客家信仰民俗與其生態意涵；介紹新型態的客家生態民俗──黃蝶祭；最後，探討從創發的傳統觀點看新舊客家民俗的文化傳遞意義。
