Inquiring into Landscape Forests Innovation Design along the Hang-xin-jing Expressway

高速公路沿线景观林建设对发展高速公路经济、展示市(县)面貌、提升休闲旅游业和减少森林灾害等方面具有重要意义。针对杭新景高速公路沿线景观林存在着树种单一、林相单调、遗留废弃地多,村庄绿化滞后,造成景观林效果差等问题,结合高速公路沿线景观林改造特点,提出景观林改造的指导思想和原则,构建常绿阔叶林、常绿落叶阔叶混交林、针阔混交林、竹林、村落绿化景观林、废弃地植被景观林、茶园景观林和边坡景观林8种景观林类型以及更新造林、补植改造、疏伐改造、封育保护和复合经营5种高速公路沿线景观林改造建设模式。
