在过去的几十年里，美国大部分地区的大型野火发生率和野火季节的持续时间都有所增加（Westerling等人，2006年，美国水务协会，2008年; Finco等人，2012年）。根据全球大气环流模型和缩小尺度的区域气候模型生成的预测气候情景进行的未来预测表明，在北方大部分地区，特别是在北美西部，野火的预期严重程度将增加，野火季节将扩大（Liu等人，2010年; Liu等人，2012年）。美国大约80%的淡水资源来自林地，3,400多个公共饮用水系统位于国家林地流域（USDA，2006）。因此，当前和预测的野火发生对用于源水和支持渔业和水生生境的径流的数量和质量的潜在影响是相当大的。
In the last several decades, both the incidence of large wildfires and the duration of the wildfire season across much of the United States have increased (Westerling and others, 2006, American Water Works Assn, 2008; Finco and others, 2012). Future projections, based on forecasted climate scenarios generated by global general circulation models (GCM’s), and down-scaled regional climate models (RCM’s) indicate both an increase in the expected severity of wildfires, and an expansion of wildfire season (Liu and others, 2010; Liu and others, 2012) over much of the northern hemisphere, particularly for western North America. Approximately 80 percent of the U.S’s freshwater resource originates on forested land, and more than 3,400 public drinking-water systems are located in watersheds containing national forest lands (USDA, 2006). Thus, potential impacts from current and forecast wildfire occurrence on the quantity and quality of runoff used for sourcewater and to support fisheries and aquatic habitats are considerable.
