Ecosystem services for poverty alleviation (ESPA) is an interdisciplinary concept provides supports to the decision–makers and natural resource users for both sustainable ecosystem management and poverty reduction. Spatially understanding the ecological benefits and limits for poverty alleviation in the coupled ecological and social perspective is required, while the practical case is still lack. In this study, a concept of landscape functional zone was introduced under the background of China’s targeted poverty alleviation strategy. The ecosystem services of carbon sequestration, soil retention and water yield were spatially classified by the algorisms of K–means++, Kohonen self–organized feature map (SOFM) neural network, and Natural Breaks (Jenks) on the watershed of three counties in China. The testing indicators included the min–max range, standard deviation and Landscape Division Index (DIVISON). The Natural Breaks scheme adjusted by K–means++ scheme was set as the final zoning scheme, and three guidelines for each county were proposed. Theoretically, landscape functional zone can be a nexus connecting landscape and policy, as spatial perspective is required for both environmental endowment & entitlement and stakeholder’s preference in targeted poverty alleviation. It is proposed that the theoretical importance of ecosystem services should be highlighted not only for rural poverty alleviation, but under a broader view of rural restructuring in developing countries.
