“…Resistance surfaces simulate the ecological processes of spatial species movements and the flow and transfer of ecological functions among different landscape types. They are primarily influenced by landscape types and natural and anthropogenic disturbances [28]. In our study, the construction of resistance surfaces is not solely focused on the ecological resistance of individual species.…”

“…To establish meaningful comparisons, the resistance values for each factor thoughtfully reclassified into five distinct levels based on the previous scientific litera (Table 2). These levels have been assigned ascending values of 1, 3, 5, 7, and 9, refle increasing degrees of resistance [28,42] (Figure 4).…”

“…To establish meaningful comparisons, the resistance values for each factor were thoughtfully reclassified into five distinct levels based on the previous scientific literature (Table 2). These levels have been assigned ascending values of 1, 3, 5, 7, and 9, reflecting increasing degrees of resistance [28,42] (Figure 4). To effectively visualize the intricate three-dimensional data within a two-d sional framework, we employed SPCA [45] to reduce the dimensionality of the resis factors.…”

“…The construction of resistance surfaces requires the quantification of natural and anthropogenic impediments to the ecology of plants and animals, such as land use/land cover (LULC) type, habitat quality, and the intensity of human activities. [27,28]. In studies involving urban areas or watersheds, resistance surfaces are adjusted by considering landscape heterogeneity, incorporating indicators such as nighttime lighting data [29] and impervious surface area.…”

In recent years, rapid global changes have accelerated the loss of habitats and fragmentation of landscapes, emerging as primary drivers of the alarming decline in global biodiversity. Through the construction of ecological networks (ENs) that simulate the interactions between animal and plant species with their environment, it is possible to mitigate landscape fragmentation and the loss of biodiversity. In this study, we focused on the ecologically diverse southeastern region of the Qinghai–Tibetan Plateau (QTP) as our research area and developed a comprehensive Multi-Species Ecological Network (MEN) consisting of ten species. Through employing complex network analysis methods, we thoroughly examined the intra-species and inter-species interactions within the MEN, integrating the findings with the natural characteristics of the study area to yield valuable insights. The results of our study revealed considerable spatial variations in the MEN. Specifically, the western and eastern regions experienced significant ecological resistance, leading to fragmented ecological sources and a limited connectivity of ecological corridors. Furthermore, the application of complex network analysis revealed inadequate connectivity and stability in specific localized areas within the MEN. This emphasizes the pressing requirement for effective ecological preservation plans. Through this study, our aim is to advance research on multi-species ecological spatial networks and to offer novel perspectives and methodologies for biodiversity conservation and habitat maintenance in the Qinghai–Tibetan Plateau.

“…First, most current research adopted a single perspective to identify ES. For instance, some studies focus on landscape change patterns or ecological functions in one aspect [20,24] but still need to fill the gap in different aspects. Second, connectivity and integrity are of great importance to the ecosystem [25], but it is challenging to consider the spatio-temporal continuous ES in recent identification methods.…”

As a crucial component of the ecological security pattern, ecological source (ES) plays a vital role in providing ecosystem service value (ESV) and conserving biodiversity. Previous studies have mostly considered ES only from either landscape change pattern or ecological function perspectives, and have ignored their integration and spatio-temporal evolutionary modeling. In this study, we proposed a multi-perspective framework for the spatio-temporal characteristics of ES by ESV incorporating landscape aesthetics, carbon sink characteristics, ecological quality, and kernel NDVI (kNDVI). By integrating the revised ESV and the kernel normalized difference vegetation index as a foundation, we employed the spatial priority model to identify ES. This improvement aims to yield a more practical and specific ESV result. Applying this framework to the Three-River Headwaters Region (TRHR), a significant spatio-temporal change in ecological sources has been observed from 2000 to 2020. This performance provided a reference for ecological conservation in the TRHR. The results indicate that this ecological source identification framework has reliable accuracy and efficiency compared with the existing NRs in the TRHR. This method could reveal more precise spatio-temporal distributions of ES, enhancing ecosystem integrity and providing technical modeling support for developing cross-scale spatial planning and management strategies for nature reserve boundaries. The framework proposed in our research could serve as a reference for building ecological networks in other ecologically fragile areas.
