摘要

野火可能会造成生态系统破坏,需要采取火灾后的缓解和/或恢复行动。问题是,为了规划和优先考虑恢复项目,识别那些表现出高退化风险的燃烧区域的标准是什么。为了解决这个问题,有必要从火灾影响的分析开始,并从分析中得出用于评估被烧毁生态系统的脆弱性和再生能力的预测工具。火灾后退化机制的确定为制定相应的具体缓解/恢复行动提供了基础。对野火生态影响的诊断以及既定的森林管理目标,可以制定缓解/恢复战略和随后的实施项目。我们介绍了我们在火灾后生态系统脆弱性评估和恢复规划评估方面的经验,这些经验来源于最近和正在进行的EC研究项目。这包括开发适合退化土壤和地中海干旱条件的短期恢复技术,在地中海干旱条件下,火灾引起的退化与植被再生的缺水相结合。

Restauración de montes quemados en condiciones mediterráneas
Wildfires may produce ecosystem damages that would require post-fire mitigation and/or restoration actions. The question is what are the criteria to identify those burned areas that show high degradation risk in order to plan and prioritise restoration projects. To address that question it is necessary to start with the analysis of fire impact, and from that analysis to derive predictive tools for assessing the fragility and regeneration capacity of burned ecosystems. The identification of post-fire degradation mechanisms provides the basis for developing the corresponding specific mitigation/restoration actions. The diagnostic of ecological impact of wildfires together with the established forest management objectives allow deriving mitigation/restoration strategies and the subsequent implementation projects.We present our experience on the evaluation of post-fire ecosystem vulnerability and on the assessment of restoration planning derived from recent and ongoing EC research projects. This includes the development of short-term restoration techniques suited for degraded soils and dry Mediterranean conditions, where fire-induced degradation is complicated with water shortage for regenerating vegetation.
