Peat fire,air pollution and hydrological processes in a tropical peatland,Central Kalimantan,Indonesia

摘要

Dense haze emitted from peat/forest fires in 1997/98 and 2002 damaged not only the peatland and forest themselves but also the social activity and human health in many countries of South-east Asia.Several components of air quality,such as carbon monoxide,ozone and particulate matter less than 10 μm in diameter (PM_(10)) etc.have been monitored since 2001 by the Environmental Impact Agency of Palangka Raya at three sites in Palangka Raya,Central Kalimantan.Peat moisture of the surface layer,which is a very important factor for surface peat to be ignited by sparking fire,was estimated with the one-dimensional bucket model of hy-drological processes in the peat layer from surface to one metre in depth.The seasonal changes of concentrations of carbon monoxide and PM_(10) clearly coincided with changes of peat moisture of the surface layer.^
