摘　　要：对安徽淮河堤防I-69杨防护林生长与土壤养分关系进行了调查分析，结果表明，不同立地条件下杨树防护林生长差异显著，10～12年生林分年平均蓄积生长量为10．45—23．27m^3·hm^-2·a^-1，林分生产力水平的高低主要受控于土壤有机质含量及氮、磷有效性。Relationship between growth ＆ soil nutrients for Populus deltoides ev. ＂Lux＂ shelterbelt of Huaihe River embankment in Anhui province was investigated. Result shows that： there are significant differences in growth of poplar shelterbdt under different sites ; the annual mean volume increment for the stands of 10-12-year-old ranged from 10.45 to 23.27 m^3·hm^-2·a^-1 ;the stand productivity was greatly controlled by soil organic matter content and the availability of nitrogen ＆ phosphorus.
