Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…This method emphasized the selection of an optimal path for species movement. The principle is as follows (Zhang et al, 2021)where MCR refers to the value of minimal cumulative resistance; D ij represents the species spatial distance from source point j to patch i ; R i is the ecological resistance coefficient of spatial unit i to species movement; f refers to the positive correlation function between ecological process and the MCR; and min is the MCR value of i from different sources.…”

China’s Ecological Conservation Redline (ECR) program ensures the coordination and sustainability of natural and economic development while maintaining regional ecological security. Current research focuses on the ecosystem services within ECR areas but ignores cross-boundary ecological flow and the interactions between the internal and external ecological effects of ECR areas. In addition, the ecological background has spatial continuity that is not limited by boundaries, and the radiation effect areas extending beyond ECR areas have not been quantified. In this study, the Beijing ECR areas and ecological security network were integrated in order to connect the ecological process and landscape pattern to the ECR through the circulation path of ecological corridors, and cross-boundary effects between patches were examined. The field spread model was used to quantify the radiation influence range of ECR areas. Additionally, 972.46 km of ecological corridors were identified in Beijing, and abundant corridors effectively linked the ECR areas and maintained the material cycle. In the surrounding areas, ecological corridors were spread radially, with a total length of 941.85 km, promoting cross-boundary ecological flow between the ECR and surrounding source areas. This study used 25 ecological nodes to constitute the cross-boundary ecological security network system. The total radiation area based on the ECR source was 9572.16 km2. These results provide support for the radiation effect of ECR and cross-boundary ecological flows and suggest a useful model for sustainable ecological development and cross-boundary management.

The structure and function of ecological spaces play a crucial role in resisting risk interference and providing ecological services. Conducting resilience assessments of ecological spaces is of great significance for maintaining ecological security. Taking the Baiyangdian Basin as the research object, based on the evaluation results of ecosystem service function importance and ecological environmental sensitivity, the ecological space importance level of the Baiyangdian Basin is divided. Based on the three basic characteristics of “resistance, adaptability, recoverability”, the resilience of ecological space model was constructed by selecting ecosystem service value, landscape structure stability, ecological resilience model and coefficient. The research results show that: (1) The overall importance index of ecological space in the Baiyangdian Basin is relatively low. The non-critical area accounted for 43.00% of the total area, the general area accounted for 30.78%, and the core area accounted for 26.22%, which mainly distributed in the northern part of the study area and at the confluence of rivers. (2) The proportion of areas with extremely important ecosystem service functions in Baiyangdian Basin is 31.73%, concentrated in the central and southwestern parts of the basin. The highly sensitive ecological environment areas accounted for 21.96%, mainly distributed in high-altitude areas in the northern part of the basin and river convergence areas. (3) On the whole, the overall resilience level of the study area is not high and there is a significant difference in resilience between the north and south, with 68.60% of the regions in the low level of resilience. The area with high resilience level accounted for only 1.51%, and the highest resilience level was found at river confluence. The research results provide a theoretical basis for maintaining and improving the ecological environment of the basin, and provide a basis for implementing precise policies to optimize the ecological space of the basin.
