中文摘要 | 濕地生態系的開發與保存,常為保育團體與開發單位爭論之話題,本文嘗試以國 內外常用之族群大小、歧異度、代表性、面積及稀有性等準則,列出相關的標準,做出濕地 評估指標數值,再將該數值換算成生態重要性等級,做為濕地間優先保存順序之參考。經指 標計算,大肚溪口為 81 分,蘭陽溪口為 75 分,關渡為 72 分,無尾港為 55 分;其中大 肚溪口為國際性重要,蘭陽溪口及關渡為國家性重要,無尾港為區域性重要。目前關渡、蘭 陽溪口及無尾港已列入保護區或保留區之保存系統,然而大肚溪口尚未列入保護系統,值得 作為決策者對該濕地在開發利用規劃前之參考。 |
英文摘要 | This study is conducted form ecological points of view for the setting of nature reserve. We discuss the method for assessing the ornithological interest of sites for conservation. Ornithological interest can be classified into five groups(site"attributes"), and each attribute can be measured using quantitative criteria. The five attributes are (1) area, (2) diversity, (3) rarity, (4)population size and (5) representativeness. Ecological importance of a nature reserve can then be specified according to its score, In our examples, Tatu river in international important (81 in score), Lan-Yang river (75 in score) and Guandu (72 in score) are national important, while Wuwen port is regional important (55 in score). Therefore, Tatu river and Lan-Yang river should be put in higher priority as nature reserve from ecological viewpoint. |
