Abstract:[Objective] The construction of a urban integrated ecological security pattern was studied in order to provide scientific references for special studies such as urban master planning and urban ecological planning.[Methods] Taking Yanping District of Nanping City, Fujian Province as the research object, the ecological source land was selected on the basis of the ecological protection red line. The terrain gradient, land cover and vegetation cover were used as the resistance factors, and the minimum cumulative resistance model was applied to the mutation point of the ecological resistance surface histogram distribution. 2 983 and 9 268 are the boundaries, and the bottom line type, buffer type and ideal ecological security pattern of Yanping District are constructed respectively.[Results] The ecological source area of Yanping District, namely the bottom line ecological pattern, covered an area of 534.51 km2, accounting for 20.10% of the Yanping District. The buffered and ideal ecological security pattern covered an area of 771.17 km2 and 1 592.79 km2 respectively, and accounting for 29.00% and 59.89% of Yanping District. Combining three different levels of safety and ecological security, the 13 ecological corridors and 5 key ecological nodes between the ecological sources were further clarified, and the comprehensive ecological security pattern of Yanping District was formed.[Conclusion] On the basis of the ecological protection red line, combined with the characteristics of Yanping District which is a landscape-type city, the ecological land distribution patterns of different safety levels, ecological corridors and key ecological nodes are determined, and the comprehensive ecological security pattern of Yanping District is formed.
