摘　　要：对顺义、菏泽和廊坊3个地区的欧美杨107按不同立地条件以及不同树龄分类,分析其化学组成。研究结果表明,顺义壤土5年生的欧美杨107化学组成最适宜制浆造纸,其苯醇抽出物含量0.82%,综纤维素含量80.86%,木素含量22.08%;菏泽沙壤土5年生的欧美杨107苯醇抽出物含量过高,达到2.03%,综纤维素含量最低,仅有78.87%,最不适宜作为造纸原料。对立地条件相同的欧美杨107,4年生以廊坊沙土的较好,5年生以顺义壤土的最好,6年生以菏泽沙壤土的较好;对树龄相同的欧美杨107,菏泽沙壤土以6年生的最好,廊坊沙土以4年生的最好。顺义壤土比沙土更适宜种植欧美杨107。The passage mainly classified Populus×euramericana cv.＇74/76＇ by different soils and different tree-ages, analyzed their chemical compositions. The results showed the 5 tree-ages Populus×euramericana cv.＇74/76＂ growing in Shunyi loam soil has the best chemical components character. The content of alcohol benzene extractive is 0.82%, the content of holocellulose is 80.86%, the content of lignin is 22.08%. The 5 tree-ages Populus×euramericana cv.＇74/76＂ growing in Heze sand loam soil has the worst chemical components character. The content of alcohol benzene extractive is 2.03%, the content of holocellulose is 78.87%. Among the same soil trees, the Langfang sand soil＇s is better in 4 years old, the Shunyi loam soil＇s is the best in 5 years old, the Heze sand loam soil＇s is better in 6 years old. Among the same age trees, the Heze sand loam soil＇s is the best in 6 years old, the Langfang sand soil＇s is the best in 4 years old. Sand soil is more suitable to plant Populus×euramericana cv.＇74/76＂ than loam soil in Shunyi.
