摘　　要：中国对大叶杨的研究极少,尚属起步阶段,为了更好地开发利用优良乡土树种资源,本文以乡土树种大叶杨为研究对象,对分布在宜昌市大老岭林场和建始县长岭岗林场的大叶杨天然林分生长情况进行调查,采用综合评分法选出12株优树,为湖北省大叶杨种质资源保存和开发利用奠定了基础。The few research on Populus lasiocarpa and is still in its infancy in China. In order to devel- opment better and utilization of local fine tree species resources, the Poputus lasiocarpa was researched in the paper. We investigated the distribution and growth of natural forests of Populus lasiocarpa in Dalaoling Forest Farm in Yichang and Changlingang Forest Farm in Jianshi County. The Comprehensive evaluation was used to select plus tree. We selected twelve plus trees finaly and this work laid the foundations of resources save and exploitation of Populus lasiocarpa in hubei.
