摘    要:
在分析阻力面模型概念的基础上,基于景观生态安全、自然保护区设计等理论,提出了森林景观水文功能安全阻力面模型。认为它可以由安全源、安全缓冲区、安全外围区等要素构成。在构建理论的基础上,还以大兴安岭毕拉河林业局为研究对象进行了案例研究。研究结果发现:由于近十年人类干扰的不断加强特别是森林采伐与毁林开荒,森林水文安全阻力面各要素发生了一定变化,突出表现在安全核心区面积增加,安全外围区面积缩小。

关 键 词:森林景观  水文功能安全  阻力面模型

Abstract:
A resistance model of forest hydrological ability, which is derived from the theories of landscape ecology security and nature reserve division and concept of resistance surface model, is put forward in this paper. This model is composed of such elements as security sources, security buffer area and security periphery area etc. Based on the model, a case study of Daxinganling Bilahe Forestry Bureau was carried out. The results showed that the elements in the model has been changed due to the gradually stronger human intervention especially deforestation and exploitation. The security core area is expanding while the security periphery area is shrinking.
