The purpose of evaluating the ecosystem service value (ESV) is to monetize different kinds of ESs and to account for natural resource assets from an economic point of view that can be used as a reference for ecological protection policy formulation and land use structure optimization [35]. This method can accurately quantify differences in the importance of ESs and is suitable for large-scale research, but there are still few studies identifying ecological sources based on the ESV [36]. Existing research on ESV calculation using land use types also ignores the differences in the ESs within the same land use category. Therefore, it is necessary to characterize the spatial and temporal distribution of ESs as the basis for the accurate adjustment of the ESV [37]. As a kind of important landscape element connecting discrete ecological sources, ecological corridors can promote the flow of materials, energy, and information among different landscapes and maintain the integrity and continuity of landscape ecological processes [38; 39]. Extracting and protecting critical corridors will help to increase the connectivity and stability of regional ecological networks and improve the quality of ESs. At present, the general methods for extracting ecological corridors include the minimum cumulative resistance (MCR) model and the circuit theory model [40]. The MCR model identifies corridors by simulating the minimum cost path for species to pass through different landscapes from the source [41; 42]. This method is mature and requires fewer data. The circuit theory model comes from physics and is more in line with the characteristics of biological behavior [43]. The two methods have their advantages and disadvantages and complement each other. As research on the construction of ESP deepens, scholars continue to improve and innovate ecological source identification and ecological corridor extraction methods, but most of these methods put forward suggestions for the improvement of ESP from the perspective of social ecology. These methods remain at the application level but lack an in-depth discussion of ecological processes and landscape elements [44]. In the study of landscape elements, the extraction of ecological corridors using the MCR model reflects the spatial distribution of corridors but does not reveal their inherent characteristics. In fact, ecological corridors can maintain the functional connectivity of ecological networks, while good connectivity plays an important role in maintaining gene flow [45; 46], natal dispersion [47], animal population dynamics [48], and biological migration [49]. Therefore, it is necessary to study the connectivity of ecological corridors. The research of [PERSON] et al. [50] indicates that the characteristics of ecological corridors can be shown in the importance of providing a connection between two ecological sources and its contribution to maintaining the overall connectivity of the ecological network. Among them, species migration is compared to current flow, and the contribution of ecological corridors to connectivity can be obtained by simulating the current between ecological corridors, while the importance of ecological corridors can be calculated by the gravity model that is used to simulate the connection strength between sources [51]. Based on this, the priority of ecological corridors can be determined, and the order in which protection should be prioritized can be determined afterward. In China, there is a lack of a set of systematic long-term operation paradigms for the protection and functional restoration of ecological corridors, which are particularly evident in provinces and cities with low financial levels that are experiencing a fierce conflict between economic development and ecological protection [34]. How to use limited financial resources to protect the ecological environment as much as possible is a key point for the government to consider when formulating ecological protection policies.
