步道是进行娱乐活动的主要娱乐资源设施。它们提供了通往非道路区域的安全通道，为徒步旅行、骑自行车和观察野生动物等娱乐活动提供了支持，并通过将游客交通集中在抗道路上来保护自然资源。然而，越来越多的娱乐用途，加上设计和/或维护不善的小径，导致了各种各样的资源影响。步道管理者需要关于步道及其状况的客观信息来监测趋势，指导步道维护工作，并评估游客管理和资源保护行动的需求。本文综述了道路影响和不同类型的道路评估，包括清单、维护和状况评估方法。通过对大烟山国家公园阿巴拉契亚山径15英里路段的独立评估，对两种评估方法——点抽样和问题评估进行了实证比较。结果表明，点抽样和问题评估方法产生的定量信息类型明显不同。点采样方法提供了更准确和精确的测量痕迹特征是连续的或频繁的（例如，胎面宽度或暴露的土壤）。问题评估方法是监测轨迹特征的首选方法，这些特征可以很容易地预先定义或不常见（例如，过大的宽度或二次足迹），特别是当需要关于特定轨迹影响问题的位置的信息时。这两种评估方法的优点和局限性进行了审查，关系到各种管理和研究信息的需求。讨论了这些评价方法的选择和应用。
Trails are a primary recreation resource facility on which recreation activities are performed. They provide safe access to non-roaded areas, support recreational opportunities such as hiking, biking, and wildlife observation, and protect natural resources by concentrating visitor traffic on resistant treads. However, increasing recreational use, coupled with poorly designed and/or maintained trails, has led to a variety of resource impacts. Trail managers require objective information on trails and their conditions to monitor trends, direct trail maintenance efforts, and evaluate the need for visitor management and resource protection actions. This paper reviews trail impacts and different types of trail assessments, including inventory, maintenance, and condition assessment approaches. Two assessment methods, point sampling and problem assessment, are compared empirically from separate assessments of a 15-mile segment of the Appalachian Trail in Great Smoky Mountains National Park. Results indicate that point sampling and problem assessment methods yield distinctly different types of quantitative information. The point sampling method provides more accurate and precise measures of trail characteristics that are continuous or frequent (e.g., tread width or exposed soil). The problem assessment method is a preferred approach for monitoring trail characteristics that can be easily predefined or are infrequent (e.g., exces- sive width or secondary treads), particularly when information on the location of specific trail impact problems is needed. The advantages and limitations of these two assessment methods are examined in relation to various management and research information needs. The choice and utility of these assessment methods are also discussed.
