摘　　要：本文采用数量化地位指数方法实现了小青杨、北京杨、小钻杨、健杨等辽西主要适宜杨树种类间的立地质量代换评价，建立了６对树种转换评价的配对方程。在此基础上进行了适地适树分析，将江西河滩地分为５个地力等级，分析了不同立地条件下各树种生长特性，在高地位质量条件下健杨生长最好，在中等立地条件下小钻杨为最优造林树种，在立地条件较差时小青杨、小叶杨较为适宜，北京杨则不作为辽西今后大力发展的树种。最后为不同地力等级内的各立地类型设计了最优造林树种和主要的改土培肥措施。On the basis of the site classification of poplar plantations along river banks in western Liaoning province,by means of quantified site index,the site quality was evaluated by the substitution of tree species in the Same types, 6 substitution equation pair were established for 4 poplar species, and the species growth characteristics were analysed. Then, the river banks in estem Liaoning province were divided into 5 productive classes. The best suitable poplar species were selected for each useful site type, and the soil improving ways were determined for different forest types.
