“…As of 2020, the basin had a permanent population of 466,700, including 280,700 urban residents and 186,000 rural residents. In recent years, driven by ecological protection policies and influenced by human production and life, the ecological security of the Shule River Basin has been challenged and given opportunities to varying degrees [41].…”

Ecological security evaluation and land space governance are effective ways to ensure regional ecological security and realize sustainable development. This study evaluated the ecological security status at the raster scale and conducted research on the restoration and governance of the national territory, with the aim of implementing accurate restoration, reducing ecological restoration costs, and increasing ecological restoration benefits. Taking the typical arid inland river Shule River Basin as an example, this study selected evaluation factors from production, living, and ecological perspectives, obtained the influencing factors of regional ecological security by spatial principal component analysis, and calculated the ecological security index on the grid scale of production, life and ecological space. The macro-scale national parks, ecological protection red line and other realistic constraints are combined with the grid-scale ecological security evaluation results to achieve accurate land space restoration and governance. The results show that the ecological space accounts for 79.23%, and the production space only accounts for 7.47%, which is similar to other inland river basins in arid areas. The study found that per capita GDP and distance to the road have a significant impact on the ecological security of the study area from the perspectives of production and life, while distance to the water, vegetation coverage, and land cover have a significant impact on ecological security from the ecological perspective. Moderate, moderate low and low ecological security zones account for 72.09% of the total area of the basin, indicating that the ecological security guarantee ability of the Shule River Basin is low. The ecological security level of the living space was the lowest, and the ecological security pattern of the basin area as a whole presented a “higher in the north and south and lower in the middle” characteristic. The land restoration and governance of the Shule River Basin area was divided into five types of ecological control, ecological conservation, ecological enhancement, ecological restoration and ecological management, of which the ecological control area accounted for as much as 35.86%, implying that ecological security in the Shule River Basin has attracted sufficient attention from the government. It is considered that the management of production and living space is more difficult, complex and important, and the proportion of space is relatively small, so it is necessary to focus on the comprehensive management project of ecological protection and restoration. However, the ecological endowment conditions of ecological space in the Shule River Basin are relatively poor, and the distribution area is vast, so natural restoration should be given priority, supplemented by artificial restoration. This study provides a reference for regional ecological security evaluation, ecological civilization construction, and national ecological security research and practice.

“…Optimizing the patterns of land space development and protection, as well as enhancing regional ecological security, are important tasks in ecological civilization construction [1,2]. The 15th meeting of the Conference of the Parties to the Convention on Biological Diversity (CBD COP15) was held in Yunnan in October 2021 to promote the conservation of biodiversity and the sustainable utilization of its components.…”

“…Yunnan Province is in a critical phase of social and economic development, and the construction of ecological civilization can alleviate the dual pressures of economic development and ecological protection [3,4]. Constructing an ecological security pattern (ESP) is an important strategy to guarantee regional ecological security [2]. Effective connection of fragmented habitat patches by building an ecological network can improve the quality of the ecosystem and conserve biodiversity [5,6].…”

“…At present, the construction of ESPs is a well-defined research topic, and ESP construction is currently carried out through the basic paradigm of "identifying ecological sources-constructing resistance surfaces-extracting corridors" [2,13]. Some researchers have also considered "ecological pinch points" and "ecological breakpoints" for the construction of ESPs [14][15][16].…”

“…To connect ecological sources, an ecological network is formed by the cross-connection of nodes and corridors. The energy, material, and information flows among different landscape elements are carried out through the network [2]. The minimum cumulative resistance model is widely used for the extraction of ecological corridors.…”

Study on the Construction of the Ecological Security Pattern of the Lancang River Basin (Yunnan Section) Based on InVEST-MSPA-Circuit Theory

Optimizing the pattern of land space development and protection as well as improving regional ecological security are significant tasks in the construction of an ecological civilization. The Lancang River Basin is a significant ecological barrier in Southwest China, and its ecological security is critical to the Natural World Heritage Site of “Three Parallel Rivers” and even to Southeast Asia. In this study, the InVEST model and MSPA method were used for the identification of the ecological sources; the resistance surface was corrected by the night light coefficient; and the ecological linkages, pinch points, obstacles, and ecological breakpoints were extracted using the circuit theory to construct the ecological security pattern of the Lancang River Basin. The major study results indicated that: (1) A total of 23 ecological sources were identified in the watershed, covering an area of 9019.56 km2, mostly large-scale irregular patches. (2) A total of 39 ecological corridors were identified in the study area; 15 key corridors, 17 important corridors, and 7 general corridors were extracted based on the gravity model, which together formed a ecological security network for the watershed. (3) Sixteen ecological pinch points, one primary ecological improvement area, twelve secondary improvement areas, and twenty-nine ecological breakpoints were identified in this study. The ecological protection and restoration of different important ecological areas are conducive to the protection of biodiversity and the construction of the ecological security pattern in the Lancang River Basin.
