摘　　要：以新疆落叶松地理种源试验的代表性区试点布尔津、富蕴和哈密的种源子代综合性状的主分量结果为依据 ,参考气候因子和阻隔基因交流的自然条件 ,将新疆落叶松区划为 2个种源区和 4个种源亚区 ,即阿尔泰山种源区 (编号Ⅰ ) ,含西部种源亚区 (编号Ⅰ1)和东部种源亚区 (编号Ⅰ2 ) ;天山种源区 (编号Ⅱ ) ,含东部种源亚区(编号Ⅱ1)和中东部种源亚区 (编号Ⅱ2 )。On the basis of L. sibirica geographic provenance trial of the representative district with Buerjing, Fuyun and Hami by means of principal componant analysis and climatic factor and obstruct gene exchange's natural conditions, Larix sibirica could be divided into 2 provenances districts and 4 provenances second districts: Aertai (number Ⅰ) contain western provenance districts (number Ⅰ 1) and eastern provenance districts (number Ⅰ 2), Tianshan (number Ⅱ) contain eastern provenance districts (number Ⅱ 1) and middle east provenance districts (number Ⅱ 2).
