Abstract: Ecological security pattern construction is a fundamental approach to ensuring regional ecological security and enhancing human welfare. Taking Henan Province, a typical region of China’s main agricultural production area, as the study area, we use multi-source spatial data to calculate the high-value areas of ecosystem services and identify ecological source sites. On the basis of calculating the degree of land use development and GDP per land and population density to determine high-demand areas of the ecosystem, the ecological resistance surface coefficient is modified with nighttime lighting data, and the ecological corridor between the source site and the high-demand area is extracted using the minimum cumulative resistance model, so as to construct and optimize the regional ecological security pattern. The following results are presented. (1) The total area of ecological source sites in Henan Province is 3.02 × 10 4 km 2 , accounting for 18.12% of the total study area, which is concentrated in the mountainous areas of East Henan and South Henan. (2) The high-demand area of ecosystem services has a total area of 4.1 × 10 4 km 2 , accounting for 24.73% of the total study area, mainly concentrated in the central and eastern regions of Henan, with poor spatial matching of ecosystem service supply and demand. (3) The total length of ecological corridors is 1062.3 km, and the overall pattern forms the main corridor axes. The identification of ecological corridors focuses on the ecological demand space and puts forward suggestions for the optimization of the regional ecological security pattern based on it.
