摘　　要：基于森林资源规划设计调查数据,采用专家评价打分的方式对泗阳县杨树林地质量进行评价;根据林地质量评价结果,结合各林班林地面积所占比例大小,对泗阳县杨树林地资源以林班为单位进行适宜性等级区划。结果表明:泗阳县杨树林地的总体质量较高。其中,轻壤和砂壤分布区以及有水系分布的林区,适宜杨树生长;分布在城区、作为行道树的杨树生长状况不良;分布于果园等经济林种植区的杨树经营较为粗放,杨树质量也较低。林班中林地面积比例较大的区域适宜杨树的集约化经营,培育杨树用材林。研究结果较好地反映出泗阳县不同地域条件下杨树的生长状况和适宜性程度,对开展森林分类经营,充分发挥林地生产潜力,具有重要现实意义。Based on the data of Forest Resources Planning and Design Investigation ,with the method of expert marking evaluate the forest land quality of Poplar forest land in SiYang .According to the quality evaluation results , combined with local forest coverage size,Compartment the poplar suitability level for the unit to compartment .The results show that：the distribution of the water system comprises and light loam in texture forest region ,which is suitable for the poplar growth;Distribution of poplar trees in the city as long in poor condition;the poplar quality in orchard is low;A large proportion of forest area in Compartment favor of poplar intensive management ,contributing to the development of poplar timber construction .Results can better reflect poplar growth status and the de-gree of suitability under different geographical conditions , this study has significant meaning to carry out the local forest classified management and give full play to the forest land productive potential .
