• The West in Flames: The Intergovernmental Politics of Wildfire Suppression and Prevention
  作者：C. Davis

  DOI：10.1093/oxfordjournals.pubjof.a004911

  日期：2001.1.1

  This research examines changes in the intergovernmental policy arrangements governing the control of wildfires in the western United States. For much of the twentieth century, the policymaking structure resembled Deil S. Wright's inclusive authority model whereby fire policy was dominated by the U.S. Forest Service with the states playing a supporting role. More recently, the states have become increasingly important in the decision-making process because of changes in residential patterns and land-use preferences that require greater intergovernmental coordination in presuppression and suppression activities within urban/wildland intermix areas, the rise in the number of large wildfires within national forests, and the willingness of Congress to approve institutional arrangements that give more weight to local community interests. Thus, the current approach increasingly resembles the overlapping authority model where multiple governmental jurisdictions share decision-making responsibility on wildfire control policies.

  本研究考察了美国西部在控制野火方面的政府间政策安排的变化。在二十世纪的大部分时间里，政策制定结构类似于德尔·S·赖特的包容性权威模型，火灾政策主要由美国森林局主导，各州扮演辅助角色。近年来，由于居民模式和土地使用偏好的变化，导致城市/野地混合区内的预防和扑灭活动需要更大的政府间协调，各州在决策过程中的重要性日益增加。此外，国家森林中大型野火数量的上升，以及国会愿意批准使地方社区利益更具权重的制度安排，也推动了这一变化。因此，目前的方式越来越像重叠权威模型，其中多个政府辖区共同分享野火控制政策的决策责任。
