摘　　要：通过对由１５７个优良无性系组成的毛白杨种源试验林的研究，提出了优良无性系选择的定量公式，并对前５０名无性系进行了排序，结果表明。A normal quantitative model for selection of the advanced clones was put forward after studying on the tested provenance forests of White Poplar, Which consisted of 157 clones, the sorted 50 advanced clones were also listed. The results of related analysis showed that the main factors influencing the growth of White Poplar were annual precipitation and mean temperature in January.
