| 摘 要： | 本研究应用由植群覆盖度减少率(CR)、植相变异度(FD)及植株高度降低率(HR)等三项植群冲击介量所合成之植群冲击指数(IVI),与步道截面土壤冲蚀量之变化,自1991至2004年间,定期就游客践踏对塔塔加步道所造成之游憩冲击效应进行长期的调查监测,探讨其变迁与可能的影响因子。本文汇整14年来所完成之重要调查监测与研究成果,并提出若干建议事项供为游憩生态学之相关研究,与经营管理单位在制定或修正其步道冲击防治与管理策略时之参考。

| Abstract: | This study was conducted to investigate and monitoring the trail impacts caused by visitors' trampling.The Tataka Trail of Yushan National Park located in central Taiwan was selected as an example.In addition to the Index of Vegetation Impact(IVI),acquired through combing cover reduction(CR),floristic dissimilarity(FD) and height reduction(HR) of the indicator plant(Yushania niitakayamensis),was taken as a synthetic indicator for monitoring the extent of vegetational change,the amount of soil erosion on trail transects was adopted as indicator for trail degradation.The results of monitoring carried out from 1991 to 2004 revealed the following conclusions:1)Visitors are obviously concentrated on holidays,it leads to serious extent of vegetation impact and soil erosion caused by visitors' trampling in Tataka recreation area;2)The extent of IVI on trailside of Tataka trail was as high as 75%,and the amount of soil erosion of trail transect per year was 338.7cm~3/cm;3)Using the change of trail transect area as an indicator for estimating the degree of trail erosion considerably accords with the use of the Index of Vegetation Impact(IVI).Both parameters should be the easy and practical indicators respectively for monitoring the extent of recreational impacts on alpine ecosystem;4)Yushania niitakayamensis,a dwarf bamboo,was the most resistant and resilient undergrowth growing on simulated trails of Tataka grassland,and Miscanthus transmorrisonensis was the next.Some suggestions for management were offered to minimize the trampling impacts of the trail. |
