Ecological security pattern (ESP) is an effective way to integrate landscape patterns and ecological processes from the perspective of connectivity. Its scientific construction can promote coordinated development social system ecosystem. However, methods ESP still need be explored, most studies assume that different do not interfere with each other, then spatial overlay types ecosystem services determine source. Metropolitan area important space carrier for high-quality Chinese urban agglomeration. Taking Shenzhen metropolitan as target area, we identified sources according trade-offs sensitivity assessment OWA algorithm, revised basic resistance surface by using night light data, simulated extracted corridors combining minimum cumulative (MCR) model potential model. We 13 a total 9938.23.23 km2. The distribution them was concentrated in Huizhou Shanwei, well junctions mountain woodlands Huizhou, Heyuan, Shanwei. Notably, 66 were simulated, including 26 40 general corridors. generally exhibited spider web radial substantial heterogeneity densely distributed suburbs northern hilly regions far areas. Aggregated elements used build comprehensive which comprises sources, corridors, 4 levels surface, 24 strategic nodes. This study comprehensively considered interactions environmental processes, provided quantitative framework constructing ESP, results provide decision-making reference territorial protection restoration planning area.

Metropolitan regions usually encounter sustainability difficulties such as overexploitation of resources, severe land scarcity, and ecological degradation, resulting in the progressive collapse networks (ENs). It is therefore essential to strengthen construction protection ENs by integrating various improving quality urban environment creating a favourable living environment. Using Guangdong-Hong Kong-Macao Greater Bay Area case study, this paper, resistance indicator system that balances natural condition human disturbance rebuilt. In doing so, scheme (applicable highly urbanised areas) established simulate at more precise scale. Moreover, local evaluation model proposed spatial patterns multiple indicators are fully summarised. The findings show exhibit apparent disparity. Disturbance through activities seriously affects pattern ENs, leading structural imbalance impairment corridors. Based on our assessment, complementary corridors "two green belts" planning will improve problems. paper can provide reference harmonisation development protection, guiding scientific management spaces regions.
