英文摘要	Ecological security is premised on ecosystem services (ESs) provided by ecosystems to humans. The construction of ecological security patterns (ESPs) is an effective measure to maintain normal ecosystem function and safeguard ecological security. A static ecosystem services value (ESV) was obtained in the study area in 2000, 2005, and 2010 to calculate the change rate as the priority index. The key indicator of ESs and their quantification to characterize spatial aggregation were used as the richness index. The ESV in 2010 was then dynamically reconstructed. In addition, the ecological sources and corridors of the three security levels were extracted to form the corresponding ESPs by using the source-sink theory of landscape ecology, minimum cumulative resistance model, and geographic information system techniques. The results of this study showed improvements over the traditional method of estimating ESs by using equivalent factors. Using the dynamic, spatial and intuitive values of ESs after reconstruction, a continuous and complete ecosystem security barrier system can be formed by selecting ecological sources with powerful service functions and ecological corridors with good connectivity. This approach provides a reference for urban development and planning of ecological environment layouts in arid inland river basins. (C) 2019 Elsevier Ltd. All rights reserved.
