| 摘 要： | 路径作为生态网络组成的一个基本单元，是生态系统中物质、能量流动的通道。生态系统的结构和功能是通过生态系统中不同路径上能量和物质的流动来实现的。路径多样性是反映生态系统营养结构多样性的一个重要侧面。本文在定义基路径和等价基路径的基础上，给出了生态系统中流动路径多样性的测度

| Abstract: | aths are flow channels of energy and matter in ecosystems. The structures and functions of ecosystems are supported by the flow paths passing energy and matter. The path diversity is one aspect of the trophic structure diversity of ecosystems. In the present paper, the measure reflecting the flow path diversity in ecosystems along the path length are formulated by defining base paths and equivalent base paths. |

| Keywords: | diversity base path equivalent path econetwork ecosystem |
