摘　　要：为掌握全省杨树现有林培育实施成效,为杨树资源培育提供基础数据支撑和"十三五"杨树发展规划编制提供科学依据,我们在沿江、沿淮和淮北地区6个县(市)设置了58个标准样地,其中实施培育措施的样地42个,未实施培育措施的对照样地16个,调查了样地的立地因子、林分情况、抚育措施、生长量、社会经济效益等情况。调查结果显示,实施科学的培育措施对杨树生长具有显著促进作用。在对不同的栽植密度、不同区域杨树生长状况对比分析的基础上,就安徽省杨树适宜栽植密度、重点发展区域、杨树二代林的经营管理等方面提出了建议。In order to grasp the effects of the existing poplar plantation cultivation in Anhui province, provide basic data support for the provincial poplar resources cultivation, and scientific basis for the formulation of the 13 th Five-Year poplar development plan, 58 standard sample plots were set up in 6 counties（cities） along Yangtze and Huaihe Rivers and in Huaibei area, including 42 plots with cultivation measures and 16 plots without cultivation measures. The site factors, stand backgrounds, tending measures, increments, social and economic benefits were surveyed. The results showed that scientific cultivation measures have a significant role in promoting poplar growth. On the basis of comparative analysis of poplar growth in different areas and planting densities, some suggestions were put forward regarding the aspects of suitable poplar planting densities, its key development areas and second-rotation poplar plantation management.
