摘　　要：收集新疆落叶松 ( Larix sibirica)全分布区 1 5个种源 ,在该树种主要生态营林区—布尔津林场 ,开展 2次年度重复的育苗、造林试验。结果表明 :( 1 )种源间当年苗抽梢率、越冬保苗率、造林成活率及生长量存在显著差异 ;( 2 )种源间各项技术指标随地理因子呈现不连续变异 ,总的趋势为经度、海拔的影响大于纬度。综合考虑认为 :该营林区选择布尔津、和丰、哈巴河等林场的种源育苗、造林较为适宜。The results of tests on provenances at Buerjin Forestry Center of Larix sibirica are as follows: (1) the adaptability and growth among proverances were significantly different. (2) the technicol economic indexes among the provenances showed a uncontinue variation with geography factors. (3) it is thoutht that provenances from Buerjin, Hefeng and Baha should be used for seedling culture of afforestation in the region.
