ABSTRACT PROPOSAL # : DEB-9806440 INVESTIGATOR(S) : TURNER INSTITUTION: UNIVERSITY OF WISCONSIN The 1998 Yellowstone fires affected over 250,000 ha, creating a mosaic of burn severity over the landscape that may influence ecosystem processes for decades or centuries to come. This study will develop quantitive predictions of postfire successional pathways and their consequences for ecosystem function across the Yellowstone landscape. The principal methods to be used are mapping and monitoring of permanent plots, combined with sophisticated spatial analysis and measurements of leaf area and net primary productivity. The focus is on variability within and among the major ecosystems of the Yellowstone landscape, and on variability in their responses to a large, common disturbance. The study will also contribute to understanding of potential effects of different fire regimes resulting from either management or climate change.

摘要提案编号：DEB-9806440 调查员：特纳研究所：威斯康星大学 1998 年黄石公园大火影响了超过 250,000 公顷土地，在景观上形成了严重的烧伤马赛克，可能会影响未来几十年或几个世纪的生态系统过程。 这项研究将对火后演替路径及其对黄石景观生态系统功能的影响进行定量预测。使用的主要方法是永久地块的绘图和监测，结合复杂的空间分析和叶面积和净初级生产力的测量。 重点是黄石景观主要生态系统内部和之间的变异性，以及它们对大型常见干扰的响应的变异性。 该研究还将有助于了解管理或气候变化造成的不同火灾状况的潜在影响。
