碩士 === 大漢技術學院 === 土木工程與環境資源管理研究所 === 103 === This study started since 2012 till 2014 at Su Hua Coastal Area in Taroko National Park, is based on environment monitoring and recreational facility carrying capacity assessment. Sampling the surface water of Da Fu river and Qingshui River, followed by monitoring the water quality. At Congde , Huide and Da Qingshui recreation area, using Manual method to determine the particulate mass concentration of atmospheric PM10 and PM2.5, by analyzes the carbonaceous compound and concentration of particulate, further estimates possibly sources of the pollution. Within the most visited Congde recreation area, investigation on the amount of visitors, traffic composition of neighboring roads and the service condition of parking lots and public restrooms are carried out. The result is shown as below: Quality of Su Hua Coastal rivers remain well as the dissolved oxygen fulfilled the saturation dissolved oxygen up to 98%, the rivers possess good assimilative capacity and self purification ability. The average particulate mass concentration of PM10 in Su Hua coastal recreation area is 50μg/m3, mainly sourced sequentially from: sea-salt related ions, secondary particles, and traffic pollution. The average particulate mass concentration of PM2.5 is 16μg/m3, mainly sourced sequentially from: secondary particles, whereas traffic pollution and sea-salt related ions account for 11%. Traffic service level of neighboring roads have declined over the years, the traffic boost were mainly caused by increment in buses(capacity of 45 passengers) and passenger cars, showing that recreation activities influenced the service level of neighboring roads. As traffic flow in 2014 had reached the estimated value of target year(2036), it implies that the completion of Su Hua Improvement Engineering will cause regular traffic congestion at certain pre-built road section(original Su Hua road section) between Da Qingshui and Congde. The investigation of visitors in Congde recreation area showed that, average amount of visitors in year 2010 is 1,020 individuals; Year 2011 is 1,057 individuals; Year 2012 grew significantly to 1,619 individuals. The increment in visitors is predicted to be caused by Free and Independent Traveler(FIT) from Mainland China since July of 2014.The investigation on the condition of parking lots and public restrooms in Congde recreation area, showed that the facilities still fulfilled the demand of visitors. As passenger cars and buses had caused the service level of neighboring roads to decline from level D to E, the maximum visitors capacity is 1,900 individuals timed between 8:00am till 18:00pm of the day, which is about 69.4million in annual terms.
