“…Wu et al identified ecological sources based on ecosystem services, landscape connectivity, and nature reserves to construct an ecological security pattern to promote ecological conservation in the Black River Basin [71]. These studies fully integrated the synergistic effects of ecosystem services to the extent that the ecological security patterns that were constructed were more scientific [30]. Xiliu Ditch is in the Yellow River basin, which is the world's fifth longest river, and is the main birthplace of Chinese civilization.…”

“…Another category considers the spatial characteristics of the study area for multi-indicator ecological assessments, such as ecosystem service importance assessments [11,25], ecological sensitivity assessment [26,27], and environmental suitability assessments [28,29]. Such methods pay more attention to the functional attributes of ecosystems, as this approach is conducive to accurately extracting areas with potential environmental problems and providing an effective scientific basis for the delineation of ecological functional areas [30]. Second, the flow of ecological elements between sources must overcome resistance, and most studies integrate natural and anthropogenic disturbance factors to construct resistance surfaces that meet the current situation of the study area [31].…”

“…Most studies have constructed ecological security assessment systems from a single perspective of ecosystem service functional importance or ecological sensitivity assessment [52][53][54]. Several scholars have studied carbon sequestration capacity, soil and water conservation services, and recreational services (RCS) [44,54,55], and some scholars have applied them to alpine areas [56], watersheds [30], arid and semiarid zones [57], etc. All these studies have promoted the development of theories and methods of ecological security assessment.…”

Resource, environmental, and ecological issues have become major constraints to the development of many regions. The Yellow River Basin is an important barrier for maintaining ecological security in northern China, but it has been impacted by problems such as severe soil erosion and declining biodiversity. The rational construction of ecological security patterns is important to enhance ecosystem functions and maintain regional ecological security. In this study, a comprehensive ecological security assessment system was constructed by selecting ecosystem service importance, ecological sensitivity, and landscape connectivity to assess the ecological security of Xiliu Ditch, an ecologically fragile region of the Inner Mongolia section of the Yellow River Basin in China. The assessment results showed significant spatial heterogeneity, with medium- and low-security value areas dominating, while high-security value areas accounted for only 18.7% of the study area. Seventeen ecological sources were identified from the high-security areas, which were mainly composed of grassland, woodland, and water bodies, most of which are distributed in the southern part of the study area. Twenty ecological corridors were selected by the minimum cumulative resistance model and gravity model and classified into 15 construction corridors and 5 potential corridors. Forty-six ecological nodes were defined, including twenty strategic points, nine potential strategic points, and seventeen break points. On this basis, we constructed an ecological security pattern of “two belts, three cores, six zones, multiple corridors and multiple nodes” and proposed corresponding ecological governance measures. This study explores the ecological security pattern at the small watershed scale, which helps to realize the fine management of the Xiliu Ditch basin and, on this basis, can provide scientific support for the ecological protection and sustainable development of the Yellow River basin. In addition, the ecological security assessment system proposed in this study can provide new ideas for the construction of ecological security patterns in similar ecologically fragile areas around the globe.

“…ESP also significantly contributes to optimizing the country's spatial development, protection pattern, and regulation of urbanized regions' uncontrolled expansion. Moreover, it provides reference and decision support for ecological restoration planning of the national territory and delineation of ecological protection redlines [40,41]. Therefore, the scientific and comprehensive identification of Ecosources, quantitative measurement of Ecocorridors, and the rational construction of regional ESP play a significant theoretical and practical role in regional sustainable development [41][42][43].…”

The escalating pace of urbanization and human activities presents formidable challenges to landuse patterns and ecological environments. Achieving a harmonious coexistence between humans and nature of high quality has emerged as a global imperative. Constructing an ecological security pattern has become an essential approach to mitigating the adverse ecological impacts of urban sprawl, safeguarding human well-being, and promoting the healthy development of ecosystems. Focusing on ecosystem sustainability, stability, and integrity, this study constructed the ecological security pattern in rapidly urbanizing areas, emphasizing achieving a well-balanced integration of urban expansion and ecological preservation. Ecological sources were identified by an evaluation system of “ecosystem service function–ecological sensitivity–landscape connectivity”. Resistance surfaces were constructed by integrating natural and human factors. Ecological corridors and nodes were extracted by methods such as the minimum cumulative resistance and gravity models. Taking Nanchang City as an example, the results show that there were 15 ecological sources, primarily woodland, displaying a distinct “island” phenomenon. Additionally, there were 41 ecological corridors with a combined length of 2170.54 km, exhibiting a dense distribution in the southwest and a sparse distribution in the northeast. The city was found to encompass 122 ecological nodes, predominantly situated along the corridors near the ecological sources, indicating a strong spatial aggregation pattern. An optimized ecological security pattern of “one ring, two belts, three zones, and multiple nodes” was proposed for synergizing ecological protection, restoration, and rapid urbanizing.
