    The Yellow River Basin is one of the most ecologically fragile zones in China. Landscape ecological risk assessment and ecological security pattern construction are effective ways to find out and solve the problems of ecological environment in this region. In this study, based on LUCC and driving factors data, we evaluated the spatial distribution characteristics of landscape ecological risk from the grid scale using the ecological risk index (ERI) and minimum cumulative resistance (MCR) models, especially proposing a new method for constructing ecological security pattern from the perspective of landscape ecological risk assessment, and finally forming an ecological security pattern network composed of points, lines and surfaces. The results showed that the ecological risk of the Yellow River basin appeared a spatial distribution pattern of "High in southwest and northwest, low in other regions". The middle-low level ecological risk accounted for more than 86 % of the total area.The study has formed an ecological security pattern network consisting of 12 core ecological sources, 92 ecological nodes, 12 key corridors, 16 auxiliary corridors and 4 different controlled areas. According to these study findings, we provide ecological protection strategies of strengthening the ecological source conservation, attaching importance to the construction of ecological corridor, increasing the restoration of ecological nodes, and carrying out the zoning regulation. This study will provide a new insight for the construction of ecological security pattern network based on the results of landscape ecological risk assessment.
