“…Carrying out mutual cooperation among countries is also an important way to improve the ES of border areas. In terms of specific implementation, first, it is essential to pay attention to the ecological restoration and protection measures in the most valuable areas [78]. By distinguishing the differences in the level of ES in different regions of the study area, it helps the local government to choose the priority of policy implementation.…”

Fewer studies on ecological security (ES) in border areas limit the synergistic development of border areas in the context of rapid globalization. The study of ES in border areas of southwest China can enrich the evaluation methods, summarize the knowledge related to ES in border areas, and provide references for similar areas in the world. Therefore, twenty-five international border counties in Yunnan Province were selected to establish a system to evaluate ES; an entropy weight TOPSIS model was used to evaluate the changes in ES from 2004 to 2019. Then, an obstacle degree model was used to diagnose the factors affecting ES. The state of ES was predicted by a gray prediction model (GM) (1,1) in 2025 and 2030. The results show that an improving ES situation presented a spatial distribution pattern of high to low from the southwest to the west and east. Various factors, including fixed assets investment, per-capita fiscal revenue, per-capita GDP, food production, and water regulation, created obstacles to a desirable ES in the study area. Although the ES of border areas will maintain an upward trend under the existing development model, the number of counties that will reach a secure state of ES in 2025 and 2030 is predicted to only be 1 and 2, respectively.

“…The establishment of ecological corridors is an important measure to solve the ecosystem’s fragmentation caused by the current violent human activities and the many ecological and environmental problems that follow (Rosenberg D K,1997; Gregory A,2021). Ecological corridors are priority areas for ecological protection (Huang L,2021) and are also an essential component of the ecological security pattern. Establishing an ecological security pattern is a new idea to solve regional ecological security problems effectively (Wang C,2020).…”

Determining critical ecological protected areas at the city (county) spatial scale is crucial for coordinating regional ecological environment management, control, and governance. It is a recognized consensus in academia that human activities significantly impact natural ecosystems. Many scholars ignore this point in the research process and only use several factors to characterize human influence. Therefore, this study takes Aksu City and Wensu County, important cities and towns in southern Xinjiang, as examples, focusing on the impact of human activities on the distribution of critical ecological protection areas. First, we simulated the range, intensity, and local natural conditions of human activities in the study area using geospatial data. We created corresponding resistance surfaces (human activity resistance surface and natural landscape resistance surface). We then assign different weights to the two resistance surfaces based on several possible scenarios, resulting in different synthetic resistance surfaces. Finally, we used the Linkage Mapper plugin to identify critical ecological reserves and compared several results. The results show that: Human activities have greatly interfered with the migration and dispersal of species, affecting the distribution of critical ecological reserves. The specific performance is that in the urban center area with high intensity of human activities, the number and location of the surrounding ecological corridors change significantly with the increase in the proportion of human activity resistance and the total area remains unchanged; As part of the ecological corridors, the ecological pinch points changes with the location of the corridor, and the whole area remains unchanged; The threshold range of the restoration value of ecological barrier points is reduced. The maximum value generated by the restoration of ecological barrier points is reduced, which shows that the restoration value of ecological barrier points decreases with increased human activities.

“…The ecological network is an effective organizational form of the ecological space that can yield a comprehensive ecological structure to coordinate various types of ecological land, which can subsequently provide the general advantage of overall ecological effect pattern improvement from a global perspective [127][128][129]. Thermal environment regulation can improve the overall thermal environment pattern.…”

Urban heat islands (UHIs) constitute an important ecological problem in cities. Ecological space has a positive effect on UHI mitigation, which can be effectively organized in the form of ecological networks. In this study, the framework for structural UHI improvement based on ecological networks considering the source-corridor model is proposed to examine the spatial threshold of the thermal effect of ecological network factors. Additionally, the cooling mechanism of each constituent element in the ecological network context is further explored. The results demonstrate that (1) an obvious cold and heat island spatial aggregation distribution exists in the Xuzhou main urban area, and land of the same land use type exhibits the dual thermal environmental properties of cold and heat islands through its spatial distribution and characteristics. Ecological space is the main bearing area of cold islands. (2) The ecological network in the main urban area of Xuzhou city occurs at a moderately complex level, and the overall network efficiency is acceptable; the network connectivity is low, while the network loop distribution is uneven. (3) Ecological networks represent an effective spatial means to improve overall UHI patterns. The ecological source area cooling threshold is 300 m, and the optimal threshold is 100 m, while the ecological corridor width threshold is 500 m and 60 m, respectively. (4) Within the optimal threshold in the context of ecological networks, the temperature of ecological sources in category G land is influenced by NDBI and FVC; ecological corridors are mainly influenced by NDBI. The results can provide a quantitative basis for urban ecological network planning considering UHI improvement and a reference for urban thermal environment research within different ecological substrates and planning and control systems in other countries and regions worldwide.
