Origin of Pattern in Chaparral Vegetation Following Fire

戴维斯教授和他的研究小组将研究观察到的 模式的查帕拉尔植被在加州，并将涉及 观察到的植被恢复过程的模式， 火 目前存在两种关于恢复过程的理论和模型： 一种观点认为，植被通过随机建立 另一种认为，火前的种子模式 植物组合和新芽控制着植被恢复过程。 此外 分析其他被烧毁地区的火灾前和火灾后的模式， 调查人员将进行控制燃烧，以记录前， 燃烧植被和种子组合，火灾行为和燃烧后的种子 群聚和建群格局。 该项目将对重新植被产生重要影响 脆弱的生态系统。 它将增加我们对 环境对自然和人为干扰的反应。

Professor Davis and his research team will examine observed patterns of chaparral vegetation in California and will relate the patterns observed to the processes by which vegetation recovers from fire. Two theories and models of the recovery process currently exist: one contends that vegetation recovers via random establishment of individual plants; the other contends that pre-fire patterns of seed assemblages and sprouts govern the revegetative process. In addition to analyzing pre- and post-fire patterns from other burned areas, the investigators will conduct a controlled burn in order to document pre- burn vegetation and seed assemblages, fire behavior, and post-burn seed assemblages and establishment patterns. This project will yield important insight into revegetation processes in fragile ecosystems. It will increase our understanding of environmental responses to natural and human-induced disturbances.
