荒地-城市界面（WUI）是房屋和荒地植被相遇或混合的区域，也是野火问题最突出的地方。在这里，我们报告说，从1990年到2010年，美国的WUI在新房数量（从3080万到4340万;增长41%）和土地面积（从581，000到770，000 km（2）;增长33%）方面都迅速增长，使其成为美国本土增长最快的土地利用类型。绝大多数新的WUI地区是新住房的结果（97%），与荒地植被的增加无关。在最近的野火（1990-2015）的范围内，2010年有286，000所房屋，而1990年为177，000所。此外，WUI的增长往往导致更多的野火点燃，使更多的生命和房屋处于危险之中。如果最近的住房增长趋势继续下去，野火问题将不会减轻。
The wildland-urban interface (WUI) is the area where houses and wildland vegetation meet or intermingle, and where wildfire problems are most pronounced. Here we report that the WUI in the United States grew rapidly from 1990 to 2010 in terms of both number of new houses (from 30.8 to 43.4 million; 41% growth) and land area (from 581,000 to 770,000 km(2); 33% growth), making it the fastest-growing land use type in the conterminous United States. The vast majority of new WUI areas were the result of new housing (97%), not related to an increase in wildland vegetation. Within the perimeter of recent wildfires (1990-2015), there were 286,000 houses in 2010, compared with 177,000 in 1990. Furthermore, WUI growth often results in more wildfire ignitions, putting more lives and houses at risk. Wildfire problems will not abate if recent housing growth trends continue.
