| 生态廊道在生态规划中是重要设计要素，其宽度设定的重要依据是其对生物多样性的支撑功
能。研究从动物种群数量、群落组成和物种多样性角度，将森林廊道动物多样性支撑功能划分为三个等
级，并通过整合分析以往研究成果，分别针对鸟类、两栖类动物、爬行类动物、小型哺乳类动物和无脊
椎动物五类动物类群，确定实现相应等级所需的最小廊道宽度。分析结果表明：当宽度超过 35 m 时，森
林廊道对小型哺乳动物以外的四类动物多样性的支撑功能可达到Ⅲ类水平，即物种数量不足完整森林的
一半，且多为林缘种、广布种或种群数量稀少；当宽度超过 400 m 时，森林廊道对五类动物类型的支撑
功能均可达Ⅰ类水平，即种类丰富、涵盖了多数物种，具有林内种或稀有种或种群数量充足、满足种群
繁衍需要。 |

| Abstract: |
| Ecological corridor is an important design component in ecological planning and its ecological
service of biodiversity is crucial factor to determine the width of ecological corridor. In this study, the biodiversity
service of forest corridor was divided into 3 class based on three dimensions including population size, community
species component and species richness. By meta-analysis of published data, the width of forest corridor for each
class was calculated for birds, amphibious, reptiles, small mammals and invertebrates respectively. The results
showed the biodiversity service can be at class Ⅲ except for small mammals when the forest corridor wider than
35 m, with species no more than 50% of that of intact forest richness and most species are forest-edge species/
general species or small size population with few individuals for a specific species. While, the biodiversity service
can be at class Ⅰ for all the five animal groups when the forest corridor wider than 400 m, with most species of
intact forest including rare species or large population with plentiful individuals for regeneration. Our research
results can provide scientific basis and reference data for forest corridor design in China. |
