摘要

Unpaved forest roads are known as the major source of sediment delivered to streams in forested watershed. There is a need for improved forest road network planning systems that estimate and consider the environmental costs associated with this erosion in the planning process. This study incorporates the environmental impact of forest roads into an economic analysis for resource transportation planning. The USDA Forest Service WEPP:Road, a road erosion prediction model, was used to estimate road erosion rates and sediment delivery to streams. Based on the estimated sediment delivery, NETWORK2000, a forest transportation planning model, produced alternative road systems that simultaneously minimized transportation costs and overall sediment delivery. The methodology was applied to the Mica Creek watershed in northern Idaho, where eleven alternative road networks were developed. The results indicate that incorporating environmental impacts into transportation planning can generate alternative road networks that reduce a large amount of estimated sediment delivery at the expense of a relatively small increase in transportation costs.
