Establishing ecological-humanistic corridors as a conservation priority plays a vital role in preserving the synergistic evolution of natural and cultural landscapes in plateau regions, while simultaneously improving socio-ecological welfare for local communities. This study takes Litang County on the Western Sichuan Plateau as the research object, and based on the results of the evaluation of the importance of ecosystem services, adopts the morphological spatial analysis method and the landscape connectivity analysis method to identify the ecological source area. Eight aspects such as land use type, vegetation cover, and altitude were selected to construct a comprehensive resistance surface. The circuit theory model is used to extract ecological corridors, ecological pinch points and ecological obstacle points, and new ecological sources and corridors are planned according to the results, and superimposed and analyzed with the humanistic landscape points to construct the ecological corridors of humanistic landscape, and to put the ecological protection and inheritance of humanistic landscape into the same type of protection framework from the perspective of protection, so as to construct the ecological network of integrating ecological landscape and humanistic landscape. The results show that the total area of ecological sources in Litang County is 1621.12 km2, accounting for 11.3% of the total area of the study area. The ecological corridors showed a pattern of “north-south direction with small clusters at both ends”, with a total length of 1221.03 km. 1119 high-level pinch points with a total area of 146.65 km2 were mainly distributed in important north-south ecological corridors. 169 high-level ecological obstacles with a total area of 146.65 km2, mainly distributed on important north-south ecological corridors. 169 high-level ecological obstacle sites with a total area of 145.06 km2, mainly distributed on the corridors between the northern source areas. The α, β and γ indices of regional ecological network connectivity increased by 6.58%, 10.95% and 3.69% respectively after the addition of 2 planned source points and 16 planned corridors. The newly added corridors are connected to 10 humanistic landscapes, expanding the scope of humanistic ecological corridors.
