大树移植在城市园林应用效果的调查与分析

Investigation and analysis on application effect of large tree transplantation on urban landscape

对大树移植在城市园林应用的效果进行了调查与分析,结果表明:大树绝大多数挖掘于野生天然林或各类人工林,严重破坏了森林资源;移植成活率不高,树木长势衰弱;增加了工程建设成本,造成资源浪费和经济损失。大树移植用于城市园林弊大于利,应予以摈弃或受到必要的限制。解决对策:一是加大《森林法》执法力度,禁止挖掘森林中的大树用于城市园林;二是制定《园林绿化苗木标准》,规范苗木规格;三是加强苗木生产绿地建设,规范苗木来源,提高供给能力,满足苗木市场需求。

We investigated and analyzed the effect of large tree transplantation on urban landscape. Results showed that： large tree transplantation seriously damaged the natural forest resources as these large trees mostly dug out from wild natural and planted forests. The survival rate and growth potential of large tree transplantation were both low, and the engineering cost increased which produced resource waste and economic loss. The shortcoming of large tree transplantation was over its advantage, which showed be abandoned or restricted. Several proposals were suggested that firstly, to enhance law enforcement, and forbid application of large tree transplantation to urban landscape; secondly, to frame the greening seedling standard for seedling criterion; thirdly, to improve tree nursery construction, and increase ability of seedling supply to reach the market demand.
