Management models,afforestation technique and species selection for fuelwood in hot-dry valley and central plateau in yunnan province

The technique about species selection,silvicultural technique and manage-ment models of fuelwood forests in the central Yunnan Plateau and dry-hot river valleyin Yunnan Province were studied.By using the plot test and quantitative analysis,thespecies such as Eucalyptus maideni,Alnus cremastogyne,Acacia decurrens and A.mearnsii were selected as the suitable fuelwood species for central Yunnan areas,andthe species such as E grandis,E.exsera,Acacia torulosa E.camaldulensis and Melia azedarach were selected as the suitable species for dry-hot river valley in YunnanProvince The silvicultural technique index in central Yunnan area were:100 day oldseedings,level site preparation and 2 m×1 m spacing,while those in dry-hot river val-ley were:100 day old seedlings,site preparation with 60 cm×60 cm ditches and 2 m×1m spacing.The management models can be the combinations of fuelwood forest witheith timber forest,economic forest or protection forest.The fuelwood logging can beinitiated in the 2~3 year old stands.The stump height was variable to differentspecies.The harvest biomass in the secondary logging or in first stubble was notclarified.
