A Brief Introduction to Willow Energy Forest Research and Plantations in Sweden

In order to provide some bases for the research and development of willow energy plantation in China the willow energy forest research and plantations in Sweden are briefly introduced in this paper.Most of the fast-growing willow species and clones thatexist in Sweden to day were introduced in 17th and 18th centures from Denmark and Germany.When the oil crisis developed in 1973 and 1979,the possibility of producing energy by fast-growing willows was realised and this idea became the real incentive for willowresearch in Sweden.Since the beginning of the 90's,the environmental consequences,together with the energy policy of the government,are the driving forces for energy forest.In Sweden most of the willow energy forest research is taking at the Department of Ecology and Enviromental Research at the Swedish University of Agricultural Sciences and the research is mainly concent rated on the coppice system,expert systems and soil microbiology,genetics and breeding,diseases and entomology,biophysics,environmental consequences,and economics of short-rotation forestry.In recent years agreat progress has been made on these aspects,especially in environmentalconsequences.Practical advisory service for developing willow energy forest and the development of willow plantations in Sweden are also presented in the paper.
