摘要
本文总结了在尼泊尔珠穆朗玛峰国家公园所做的旅游影响的研究结果,调查了旅游利用和环境特点对步行道的影响。7条步行道分成208个路段,评估的总长度为90km。采用了4级评估体系对步行道的路况进行评价,用Arc/Info和Arc/View地理信息系统(GIS)对旅游利用影响的空间格局进行分析。研究表明旅游利用和道路破坏之间密切相关,但步行道位置和环境因素是同等重要的变量。本研究认为较系统、实验性的研究是必要的,这些工作能够将人类活动导致的步行道损坏和自然因素影响明确地区别开。
This study summarizes findings of a visitor impact study conducted in the Sagarmatha (Mt.Everest) National Park Nepal.The effect of visitor use,and the influence of environmental characteristics on trail conditions are investigated.Seven trails divided into 208 trail segments,and with a total length of 90 kilometers were included in the assessment.A four-class rating system has been used for the assessment of trail conditions.Arc/Info and Arc/View geographic information system (GIS) are used to analyze spatial patterns of impacts.The study indicates a strong correlation between visitor use and trail degradation.However,locational and environmental factors are equally important variables.The study concludes that more systematic,and experimental studies are needed that can make a clear distinction between humaninduced trail damage and the effects of natural factors.
