以生态学原理创建国家森林城市 建设优美人居环境

Creating National Forest City and Developing Beautiful Living Environment with Ecological Principles

阐述城市森林与城市林业的概念、城市与城市森林的范围、森林城市的涵义与创建森林城市的意义。文章的重点是以生态学原理创建森林城市,主要生态学原理是生物多样性导致生态系统稳定性原理、模拟天然林群落结构——系统性原理以及自然选择与生态适应原理,提出应用景观生态学原理使城市森林一体化,体现"岛屿生物地理学"理论,通过生态系统食物链的调节作用控制森林病虫害。

The paper described the concepts of urban forest and urban forestry, the scope of city and urban forest, the definition of forest city and the significance of creating forest city. The key point is how to create forest city with ecological principles. These principles include biodiversity maintaining ecosystem＇s stability, modeling of natural forest community structure-system, nature election and ecological adoptability, landscape ecological principle for urban forest integration, theories reflecting Island Biological Biogeography, and forest diseases and pests control by giving play to the function of food-chain in ecosystem.
