摘　　要：人工杨作为吉林省西部地区主要造林树种,起到防风固沙,改良土壤的重要作用。笔者通过对白城市三种人工杨各器官热值、灰分的测定,并进行单因素方差分析和相关性分析,结果表明:不同品种人工杨器官间热值和灰分含量差异显著,品种间人工杨去灰分热值差异性显著,干质量热值和灰分含量差异性不显著。Artificial poplar,as the main afforestation tree species in the western region of Jilin Province,plays an important role in preventing wind and sand and improving soil.The authors measured the caloric value and ash content of various organs of three artificial poplars in Baicheng City,and performed single factor analysis of variance and correlation analysis.The results showed that the caloric value and ash content of organs of different varieties of artificial poplars were significantly different.The difference in calorific value of ash is significant,but the difference in calorific value of dry mass and ash content is not significant.
