Forest ecosystem conservation practice frequently sacrifices human livelihood, since there exists a structural conflict between both aspects in the degraded forest ecosystem. To reconcile the conflict has been widely viewed as a core issue, in which the payment of ecosystem service (PES) may play a critical role in solving this issue. In order to better understand the practical effectiveness of PES and explore the solution to reconcile the contradiction between conservation and livelihood, we investigated the decadal changes in the Sloping Land Conversion Program as a PES strategy in the Qilian Mountains, a degraded forest ecosystem of northwest China, and its effects on natural and social systems across the 10-year implementation period (2001–2011). The regional NDVI of study site was promoted from 46.24% to 61.28%, showing that vegetation cover had a massive increase during the whole implementation period. Also, the PES strategy had impelled more labor forces as migrant workers into the non-agricultural industries or urban areas. The migration dynamics in three industries demonstrated that the population of primary industry followed a gradually declining trend, and its percentage in total population was lowered from 33.44% to 19.82%. According to our household survey, local farmers reduced the economic investment in agriculture, and this enabled more labor forces to be released from agricultural industry. Interestingly, the attitudes towards the PES program for local inhabitants were gradually shifted from negative at initial stage to acceptable at middle stage, and finally to positive at late stage, as a consequence of PES application. In such case, the PES-led vegetation restoration strategy has been effectively implemented, which can reconcile the contradiction between conservation and livelihood, and ultimately achieve a win-win consequence. Our study provided a successful practical paradigm of coupled human and natural system (CHANS) in forest ecosystem restoration. •We analyzed the dilemma between forest conservation and human livelihood in China.•Sloping Land Conversion Program acted as the Payment for Ecosystem Service (PES).•The PES strategy accelerated the transfer of labors into non-agricultural industries.•Livelihood improvements promoted a fine shift of farmers' attitudes towards PES.•We established a CHANS model to highlight the role of PES in forest conservation.
