摘要：Fragmentation poses threats to landscape connectivity, leading to habitat loss and degradation. Resistance surfaces have been increasingly used for modeling eco- corridor to protect biodiversity. However, there is a lack of consideration about the uncertainty originated from the weight values during resistance surface. This study selected Liaoning Province in China as the study area for the uncertainty analysis of eco-corridor construction and centrality calculation. Resistance surfaces and the   least-cost   model were used as theory, and Linkage Mapper as the tool for analysis. A spatial map of different eco-corridor results was achieved. The centrality analysis showed that the significance of multiple-level reserves and eco-corridors declined in the order of national, provincial, municipal and county levels. The relative standard deviation of uncertainty for both reserves and eco-corridors mainly clustered between 0 and 25%. ? 2016 Taylor & Francis Group, London.
