文档介绍：徐州云龙山侧柏林景观改造规划研究
摘要:城市风景林地作为城市绿地系统的重要组成部分,在改善城市环境,丰富城市景观,保护城市生物多样性等方面发挥着巨大作用。但由于受自然、历史条件的制约,徐州市的风景林地以单一的人工侧柏纯林为主,导致生态结构单一,景观单调,生态环境自我调节能力下降。要提高城市的景观多样性,维持城市的生态安全和可持续发展,必须对对单一的侧柏纯林景观进行改造。以位于市区的云龙山为例,对其改造方法进行研究,可为全市侧柏林景观的改造提供一定的指导和示范作用。

为了规范森林的抚育间伐,我国制定并颁布了很多技术规程。如1957年颁布的《森林抚育采伐规程》,采用了前苏联的分类方法,把抚育采伐列为提高林木生长量的主要措施,将抚育采伐分为4种,即透光伐、除伐、疏伐和生长伐,除此之外《规程》还规定了卫
