摘要
位於台灣最南境的墾丁國家公園範圍內，隨著屏鵝公路的開發，出現了最適切需求生態構法的物種-毛足圓軸蟹（Cardisoma hirtipes Dana，1851，簡稱陸蟹），正面臨著影響其族群繁衍的問題。在每年的六月至十月間，正是毛足圓軸蟹成蟹降海繁衍下一代的時節，此時亦為盛暑假期，但因公路的開發以及車潮的日漸增多，截斷了該蟹降海產卵及爬行上陸的路徑，導致牠非得爬過車水馬龍的屏鵝公路，才有機會順利地達到其繁衍的目的。有鑑於此，盼能藉由詳細的野外調查方法與研究，依據調查結果，使用生態構法建立一套工程方法，達到既可保留該蟹的生存空間（順利完成其生命循環），並開創遊客觀光旅遊之解說教育新據點（深度生態之旅），以及為當地居民傳遞保育觀念，進而創造生計財源（自願擔任保育相關工作），達到物種、遊客、當地居民都獲利的三贏目的。本第一期由民國91年8月29日至民國91年12月31日止，調查與研究之區域選在香蕉灣至砂島之間為依據；第二期由民國92年1月至民國92年12底，以求取全年之記錄。同時，亦將收集其他可能出現之蟹類，作為比較及生態構法之依據，且另外蟹族群之行為以為資料之存檔，供日後之參考。

英文摘要：It lies in the most south end of Taiwan, in the range of Kenting National Park. Following the development of Ping-Er Road, there is the emergence of the species that requires ecological act the most - Cardisoma hirtipes Dana (1851, CHD in short), which is facing with the issue of its species multiplication being affected. From June to October each year, it is the time for CHD becomes crab to descend in sea and reproduce its next generation, that is the holiday during the hottest time of summer. However, for the development of roads and increase of cars, it cuts off the road for the crab to descend into sea for spawning and climb up to land, as a result, the crab has to climb through the very busy Ping-Er Road, and then it is possible for the crab to multiply successfully. For this reason, it is expected that a set of engineering methods can be set up using ecological act based on the survey results, to reach the purpose of saving living space for the crab (finish its life cycle successfully), and creating the new stronghold for explanation to and education of tourists for sightseeing (in-depth ecological tour). In addition, it can convey preservation idea to local residents, further create the source for financial resource (take preservation related work voluntarily), to reach the three-win goal for species, tourists, and local residents. The first phase starts from August 29, 2002 to December 31, 2002, and the survey and research area is selected at between Hsiangchiao Bay and Sha Island; the second phase is from January 2003 to the end of December 2003, to get records of the whole year. At the same time, other crab species possibly emerging can also be collected, for comparison and as the basis for ecological act. And the behaviors of other crab species will be saved as useful information, for future reference.
