摘  要：
为确定冬瓜杨种质资源在青海省的集中分布区,对青海省6个林区的冬瓜杨种质资源林进行了调查分析。结果表明:冬瓜杨主要以片状分布或散生分布,分布在河滩地或沟底;冬瓜杨种质资源集中分布在青海省互助北山林区,面积达600hm2。通过生长性状的对比,得出青海省互助北山林区冬瓜杨优树生长状况最好,其次是孟达自然保护区,双朋西林区的冬瓜杨优树生长状况最差。利用优势木对比法,获得不同林区复选冬瓜杨优树4个品种,光皮冬瓜杨8个品种。

摘  要：
In order to determine the central concentration area of the germplasm resources for Populus purdomii in Qinghai Province,the germplasm resource forest of Populus purdomii in six forest areas in Qinghai Province was investigated.Populus purdomii which is mainly in patchy distribution and scattered distrbution,distribution of melon and Poplar is mainly distributed in the floodplain or the bottom of the ditch,and the germplasm resources of Populus purdomii are distributed in the Beishan.forest area of Qinghai Province,which is 600 hm~2.Through the comparison of growth characters,it is concluded that the growth traits of plus tree of Populus purdomii in Beishan.forest area of Qinghai Province are the optimal,followed by the plus tree of Mengda Nature Reserve,and the growth trait of the plus tree of the Shuangpeng Xilin District is the worst.Using the advantage of wood contrast method,four species of Populus purdomii,eight species of Populus purdomii var.rockii in differe fores are were obtained.
