林火与可持续发展

Forest Fires and Sustainable Development

火是全球大多数森林生态系统中一个重要的干扰因子。它形成森林的景观模式和多样性 ,影响能量流动和生物化学循环 ,特别是影响全球碳循环。目前 ,多数估计表明 ,全球每年燃烧生物量大约 92亿 t(干重 )。火是天气变化的一个主要原因 ,火、天气和人类活动是密切相关和相互作用的 ,这些相互作用可能会产生经济影响和生态影响。要实现可持续发展 。

Fire is a prominent disturbance factor in most forest ecosystems across the world. In many ecosystems it shapes landscape patterns and diversity, and influences energy flows and biogeochemical cycles, particularly the global carbon cycle. Most recent estimates indicate that the amount of vegetative biomass burned annually is in the magnitude of 9.2 billion tons (dry weight). Fire is a significant driver of climate change. Fire, climate, and human actions are highly interactive and some of these interactions may be very costly both economically and ecologically. In order to realize the sustainable development.It is necessary to build up the fire management information systems including early warning components and strengthen fire management training.
