所谓“边缘效应”是指在两个或多个不同性质的系统交互作用处,由于某些因子或系统属性的差异和协同作用而引起系统某些组分及行为不同于系统内部的较大变化。在地理学研究的对象当中,“边缘效应”是普遍存在的。地理边缘效应是指由于空间分布、物质组成或能量结构不均匀,一定地理单元主体对其相邻范围内的作用,引起地理流(物质、能量、信息)的变异、扰动、增强及减弱等
The so-called “edge effect ” refers to the two or more different nature of the system interaction, due to some factors or system attributes differences and synergies caused by the system of certain components and behavior of the system is different from the more Big change. Among the objects of geography research, “edge effect ” is ubiquitous. Geographical edge effect refers to the role of a certain geographic unit in its adjacent area due to spatial distribution, material composition or uneven energy structure, causing variation, disturbance, enhancement and attenuation of geographic flow (matter, energy, information)
