摘　　要：被苏北农民一度称为"绿色银行"的杨树,几十年间给苏北地区带来了巨大的经济效益。然而,近几年来苏北杨树飘絮严重,给人们造成了很大的困扰。通过有关数据对苏北杨树产业发展情况进行分析,根据其需求结构的变化研究导致杨树大规模飘絮成"灾"的经济学原因。结果表明:由于木材加工业快速发展,大力鼓励培育大径材,导致近成过熟林占比过大,从而飘絮暴发。提出了合理引导杨木需求结构转变,择优培育大径材等建议。Poplars,once called"green bank"by farmers in northern Jiangsu,have brought huge economic benefits to northern Jiangsu for decades.However,in recent years,catkins in northern Jiangsu are serious,causing great trouble to people.This paper mainly analyzed the development of poplar industry in north Jiangsu province through statistics and studies the economic reasons leading to the large-scale floating catkins into"disaster",according to the change of its demand structure.The results showed that:due to the rapid development of wood processing industry,the cultivation of large diameter timber was strongly encouraged,which led to a large proportion of overripe forest and the outbreak of catkins.According to the above,it put forward some suggestions,including reasonably guide the transformation of poplar wood demand structure,the best cultivation of large diameter wood and other recommendations.
