摘　　要：在丘陵山地,沙棘和刺槐是薪炭林适宜树种。刺槐薪林产量是沙棘的两倍多,刺槐比沙棘易燃,但刺槐热值低于抄棘。造林后第4～5a首次平茬,平茬间隔期刺槐2a,沙棘4a。刺槐留茬高15cm,沙棘在地表下2～3cm。0.5m×0.5m株行距的薪材产量是1m×1.5m的3倍。根据树种特性、树种组成,经营方法,将薪炭林分成4种类型:纯矮林型,混交矮林型,纯材薪两用型,混交材薪两用型。纯矮林型应用最广泛。混交林比纯林产柴量高。In the stone hilly area, Heppophae rhamnoides and Robinia pseudoalacia are optimum fuel forest specires. The fuel wood production of R. pseudoacia is twice as much as that of H. ramnoides. R. pseudoacacia is more combustible than H. rhamnoides, but its heat value is lower than that of H. rhamnoides. The first cutting is made at the fourth—fifth year after planting, and the cutting interval is 2 years for R. pseudoacacia and 4 years for H. rhamnoides. The seump height is 15cm for R. pseudoacacia and the seump height of H. ramnoidesis lower than the ground level by 2～3cm the production at 0.5m×0.5m density is 3 times as mach as the production at 1m×1.5m density. According to tree species properties, composition and management method, the fuel forests were divided into 4 types: pure coppice forest, mixed coppice forest, pure fuel forest associated with timber forest, and mixed coppice fuel forest, assaciated with timber forest. The pure coppice is applied widely, the mixed seand has a higher fuel wood production than the pure stand.
