Biomass production potential from Populus short rotation systems in Romania

摘要: The aim of this study was to assess the potential biomass production by short rotation poplar in Romania without constraining agricultural food production. Located eastern part Europe, provides substantial land resources suitable for bioenergy process-oriented biogeochemical model Landscape DNDC used conjunction with forest-growth PSIM simulate yield grown short-rotation coppice at different sites Romania. validated on five climatic conditions Central Europe. Using regional site conditions, parameters and organic carbon content soil being most important, plantations simulated areas across Romania. Results indicated a mean productivity 12.2 ± 0.5 t ha−1 year−1 coppices arable highest yields were lowland south-east west Mures valley, whereas lowest – due either temperature or water limitations found mountainous regions, Danube region Bucharest. amount abandoned past 10 years indicates that around 10% cropping 1999 (approximately 1 million ha) is available systems today. Production these would result approximately 10 tons wood per year. energy can be generated conversion may contribute up 8% national demand if set-aside are lignocellulosic bioenergy.
