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.

Building an ecological security pattern (ESP) can safeguard and improve the structure, functions services of regional ecosystems. Furthermore, it is also one significant spatial methods to mitigate conflict between conservation economic growth. Most previous researches on construction ESP have directly utilized extensive regions forestland, grassland, water area or nature reserves as sources (ESs) without weighing habitat quality (HQ) protection red line (EPRL). The ES Dawen River basin (DRB) was identified through morphological analysis (MSPA) landscape connectivity index. By employing minimum cumulative resistance model (MCR), potential corridor (EC) identified, its importance evaluated by gravity model. Simultaneously, properties HQ (ER) were analyzed. Finally, this paper proposed optimization strategy for in accordance with EPRL. results indicate that: (1) DRB contained 15 important ESs, mainly concentrated mountain forest areas. (2) 105 ECs extracted MCR model, including 35 level 1 corridors 70 2 corridors, which primarily eastern region basin. (3) Based characteristics ER, well EPRL research, "one axis, two belts five zones" constructed control strategies proposed.

Safeguarding ecological security is one of China's important development strategies. Identifying patterns (ESPs) an effective way to collaboratively develop and environmental in different regions. Currently, studies on the construction regional ESPs mainly focus innovation ecosystem service functions, ignoring differences sensitivities environments a large scale. In this paper, taking Yellow River Basin (YRB) as example, six functions were selected identify sources (ESs), sensitivity weights set according environment characteristics regions, resistance surfaces (ERSs) determined. And YRB further investigated based Minimum Cumulative Resistance (MCR) model circuit theory.
