摘　　要：根据南方主要薪炭树种的生物量、热值进行聚类分析,并结合生物生态学特性及种植推广情况进行综合评价,然后筛选出杨树、柳树、马尾松、杉木、湿地松等5种生长快、产量高、热值高、种植广泛、适合南方发展的优良薪炭能源树种。根据瑞典的生物质颗粒分类标准(SS187120)对5种薪炭林树种制成的木质颗粒燃料进行燃烧特性分析,结果发现对应的木质颗粒在水分、热值、净密度等特性方面已达到国际水平,但是5种木质颗粒燃料燃烧后,灰分值均高于SS187120的参考值,除杉木外其他颗粒均属于可熔性灰,因此在燃烧过程中容易结渣。According to the biomasses and calorific values of main fuel-wood tree species in South China, the trees were clustered by type, and comprehensively evaluated by taking into account their biological and ecological characteristics and planting and extending status. Then five kinds of excellent fuel-wood and energy tree species, which grew fast, yielded highly, had calorific values, planted widely and was suitable for planting in South China, were selected as the preferential kinds to plant for the fuel forest in the South china, such as poplar, willow, masson pine, Cunninghamia lanceolata, slash pine. The combustion characteristics of the wood pellet fuels made of 5 kinds of selected trees were analyzed according to Swedish Biofuel Standards （SS 187120）. The results show that the characteristics of 5 kinds of wood pellets （moisture content, calorific value and net density etc. have reached international level. However, after burned, the ash contents of 5 kinds of wood pellets were all higher titan that of the reference values of Swedish Biofuel Standards （SS187120）, excepting Chinese fir pellets other trees＇ pellets all are fusibility ash, so other wood pellets are ease of slagging during combustion.
