Abstract: 近年來水肺潛水已逐漸成為人們從事海洋休閒活動之一,但是隨著活動人數的增加,其對海洋環境可能產生相當衝擊,對旅遊品質(遊客感受)可能也有影響。本研究應用生態及社會承載量二途徑,探察臺灣北海岸二處潛水點(潮境與龍洞)之旅遊承載量。於2017年七月至九月與2018年五月,以錄影方式紀錄二潛點週末之潛水人次數,並據以估算當月之潛水人次數。另於2017年九月與2018年五月以穿越線調查法,計算二潛點造礁珊瑚株數,覆蓋面積及損傷株數。此外,於2017年六月至2018年五月間,以模擬影像(4級潛水人數與4級接近距離組合)問卷,評估潛水員之擁擠感受。結果顯示:二潛點每月潛水人次數以五月最低(潮境約4100人次;龍洞約4900人次),八、九月間最高(潮境約5100人次;龍洞約8100人次)。在同一月份,皆以龍洞人次數較高。二潛點皆以表覆形珊瑚最多(株數與面積)。損傷珊瑚皆以分枝狀珊瑚最多。二潛點造礁珊瑚平均覆蓋面積比例以五月較高(潮境36.8%;龍洞28.0%),損傷珊瑚株數比例則以九月較高(潮境6.4%;龍洞17.1%)。在同一月份,造礁珊瑚平均覆蓋面積比例以潮境較高;損傷珊瑚株數比例則以龍洞較高。由二潛點之潛水人次數與損傷珊瑚株數比例建立關係式,如果潮境之損傷珊瑚比例維持10%,則每月潛水人次數建議為5000人次。如果龍洞之損傷珊瑚比例維持15%,則每月潛水人次數建議為7000人次。本研究共收集257有效問卷,二潛點皆以男性(>65%),到此潛點4次(含)以上(>68%),及同組潛水人數5人(含)以上(>49%)居多。但初次到訪者,則以龍洞較多。由潛水人數及接近距離對潛水員擁擠感受之迴歸式顯示,潛水人數為正向效應,接近距離為負向效應,並以潛水人數為較重要影響因子。在二潛點,潛水員感覺擁擠之可接受人數為5位潛水員。綜合以上結果,對二潛點潛水人數之管理建議為,潮境周末每日約350人次,龍洞約500人次。如以每團人數5人計,則潮境周末每日約70團,周間每日約20團;龍洞周末每日約100團,周間每日約30團。此結果可提供臺灣北海岸未來規劃休閒潛水管理措施之參考。
Scuba diving is becoming one of the favorite activities in marine leisure for human in recent years. However, increasing in diving frequency might result in substantial impacts on the marine environment, in addition, this might also influence on tourism quality (tourism perception). In this study, ecological and social carrying capacity approaches were performed to explore the tourism carrying capacity at two diving sites (Chaojing, CJ and Longdong, LD) in the north coast of Taiwan. Monthly number of divers were estimated from recorded number of divers in two days of weekends between July and September 2017 and May 2018. Number of colonies, coverage rate and damaged colonies of reefed corals were calculated by quadrat photos along four transects at two diving sites in September 2017 and May 2018. The perceived crowding of SCUBA divers were evaluated by a series of photographs (4 levels of diver numbers with 4 levels of proximity in 16 combinations) and questionnaires from June 2017 to May 2018. The results showed that the lowest number of dives was in May at both diving sites (4100 and 4900 dives for CJ and LD, respectively), while the highest number of dives was in August or September (5100 and 8100 dives for CJ and LD, respectively). For the same month, the number of dives in LD was higher than those in CJ. The number of colonies and coverage rate of corals were dominant by the encrusting corals, while damaged coral colonies were dominant by the branching corals for both diving sites. Coverage rate of corals was higher in May (36.8% and 28.0% for CJ and LD, respectively), while percent of damaged coral colonies was higher in September (6.4% and 17.1% for CJ and LD, respectively) for both diving sites. For the same month, coverage rate of corals in CJ was higher than that in LD, while percent of damaged coral colonies in LD was higher than that in CJ. The relationship between percent of damaged coral colonies and number of dives could be estimated for both diving sites. For CJ diving site, if the target for percent of damaged coral colonies was 10%, then the number of dives should be approximately 5000 dives. For LD diving site, if the target for percent of damaged coral colonies was 15%, then the number of dives should be approximately 7000 dives. A total of 257 respondents were analyzed in this study the respondent were dominant by males (>65%), diving here for more than 4 times (>68%), and diving with more than 5 divers (>49%). However, there was more first-time diving here for LD. The relationship between number of divers and proximity on perceived crowding was analyzed by multiple regression. The results showed that the number of divers was positive effect, while the proximity was negative effect on perceived crowding. Additionally, the number of divers was the most influential factor for divers’ perceived crowding for both diving sites. The divers would perceive crowding at a threshold of 5 divers for both diving sites. Based on the above results, the suitable dives number is 350 dives per day in weekends for CJ, and 500 dives for LD. If a target of 5 divers for each diving group is considered, thus there could be 70 groups and 20 groups per day for weekends and for weekdays, respectively in CJ, and 100 groups and 30 groups per day for weekends and for weekdays, respectively in LD. These results could be useful when considering recreational diving management measures in the north coast of Taiwan in future.
