玉山國家公園步道環境因子與山難事故類型關係之分析－以玉山主群峰線為例
Relationship between Hiking Accidental Events and Environmental Factors-a Case Study of Yushan-Main-Peak Trails in Yushan National Park
摘要
玉山主群峰線的登山步道，為玉山國家公園歷年來各步道發生山難事故之冠。官方統計資料顯示在1985-2010年期間共發生67件山難事故，其中高山病27件、墜崖19件、迷途11件，三者共佔85.1%的比例。本研究主要目的在探討玉山國家公園登山步道環境因子與山難事故類型之關係，藉此評估玉山主群峰線登山步道環境之危險度。結果顯示，步道環境因子之海拔高度、坡向、坡度與山難事故類型之高山病、墜崖、迷途皆有顯著的關係，三種主要山難事故以發生於海拔3,000~3，500 m、南向坡、坡度0~30°的步道環境的次數最多。依據67件山難事故發生地點的環境特徵，本研究評估完成玉山主群峰線十五段路線的環境危險度，並以第一段與第十三段為例，提出登山安全資訊說明，提供登山健行者參考，期以減少或預防山難事故發生的必要性。

The hiking accidental events (HAE) over the years in the area of Yushan National Park were mostly happened around the 15 sections of the Yushan-Main-Peak Trail (shortened YMP Trail). An official record showed that acute mountain sickness (AMS), falling off cliff, and getting lost are the major types of HAE which accounts for 40.3%, 28.4%, and 16.4%, respectively, of the total 67 events. The main purpose of this study was to assess the hiking risk on the YMP Trail and also to explore the relationship between environmental factors of the hiking trails and HAE. Results showed that HAE was significantly related to the environmental factors such as altitude, aspect, and slope. Briefly, the AMS occurred mostly at the locations where the trails were within the altitudes 3,000-3,500 m, the south aspect, and the slope around 0-300°. Based on the environmental features derived from the official records of the hiking accidental events, the hiking risk for the fifteen sections of the YMP Trail in Yushan National Park were estimated. A draft of instruction to hiking safety was also proposed by taking account the terrain features of the sections No. 1 and No. 13. This guide should be able to help reducing the probability or the frequency of hiking accidental events in the future.
