Constructing an ecological security pattern (ESP) is effective measure to solve current regional problems, alleviate the contradiction between rapid urbanization and protection, provide important spatial path for management of ecosystems. This study integrated importance ecosystem services, sensitivity, landscape connectivity, resistance, constructed ESP in Huang-Huai-Hai Plain using analytical hierarchy process (AHP), minimum cumulative model (MCR), gravity model. A total 13 sources, 52 corridors (22 first-level corridors, 9 s-level 21 third-level corridors), 201 nodes were identified. The sources mainly distributed around Plain, showed a circular distribution, while at intersection several corridors. In addition, built-up land increased by 40% past 20 years, posing serious threat especially adjacent cities such as Beijing, Jinan, Qingdao, well crossing urban areas Tianjin, Zhengzhou. methodological system this can theoretical foundations support construction implementation protection other regions.
