摘　　要：刺槐因其抗性强、生长速度快、薪材产量和热值均较高而成为许多地区的重要燃料型能源树种。针对北京石质山地优良高产燃料型能源刺槐无性系的筛选进行了较为深入的研究,从造林成活率、林木萌芽物候期、两个采薪周期树高和地径生长、两个采薪周期产薪量等方面对鲁刺12个无性系、豫刺6个无性系以及当地刺槐的差异进行了比较。研究结果表明,豫8059号、豫8033号和豫8017号等是适应北京石质山地立地条件的优质高产无性系,豫8026号、豫8062号和鲁9号也有潜力。建议在华北石质山地通过试验推广所选出的豫8059号、豫8033号、豫8017号和鲁9号等刺槐无性系,并推广其优化栽培配套技术。Because of its high tolerance, fast growth, high yield and calorific value, black locust （Robinia pseudoacacia L. ） was the main fuel wood species in many districts. The selection of high yield and quality fuel wood clones of black locust in the stone mountain areas of Beijing were done in this paper. The survival percent of seedlings, the phenology and the height and diameter of trees in coppice forest, and the fuel wood yield in two harvest cycles were compared among 12 clones from Shandong province, 6 clones from Henan province and local variety. The results showed that YU8059, YU8033 and YU8017 were the best clones of black locust due to their high yields and quality fuel wood in the stone mountain areas of Beijing, and YU8026, YU8062 and LU9 were also potential clones in this areas. Therefore, these selected black locust clones and their silvicultural techniques should be extended in the stone mountain areas of north China.
