Based on the frameworks of human appropriation of net primary productivity (HANPP), a hypothesis of ‘NPP tradeoff’ was proposed in this paper. This hypothesis assumed the tradeoffs among ecosystem provisioning and regulating services were influenced by the distribution ratios of the HANPP components. A methodology of measuring the effects of ecological restoration aiming at promoting the provisioning and regulating services simultaneously was established based on the ‘NPP tradeoff’ hypothesis. In this paper, three ecological restoration scenarios were set up in Bailang village, Lhasa river regions, Tibet. These scenarios were ‘before restoration’, ‘synergized promotion’, and ‘forage planting at the plain’. The HANPP components, spatial distribution, as well as the ecosystem services of livestock herding, ecosystem carbon stock, and air purifications were quantified based on the sampled data. The results showed that the livestock of 15990 sheep unit were herded in the village before the ecological restoration. The HANPP was 35.0 g C/m², occupying 13.8% of the potential NPP, in which 40.0% were occupied by the HANPP_harv. The air purification service and the carbon stock service were 12.0 g SO₂ m^-2 a^-1 and 6245.4 g C m^-2 a^-1, respectively. After the ecological restoration of ‘synergized promotion’, the total amount of HANPP kept constant, while the components proportions varied. In detailed, the HANPP_harv increased by 4.2%, and HANPP_luc decreased 1.8%. In correspondence, the herded livestock increased by 6.3% and ecosystem regulating services kept constant. In the scenario of ‘forage planting at the plain’, the total amount of HANPP decreased by 67.0% comparing to the scenario of ‘before restoration’, and the components also varied. The HANPP_harv was 2525.8 g C/m² and increased by 84.2%, while the HANPP_luc decreased by 167.0% with -14.2 g C/m². In this scenario, the number of herded livestock increased by 2.2 folds (35195.0 sheep unit). The air purification service increased by 15.1% (13.8 g SO₂ m^-2 a^-1), carbon stock service increased by 5.0% (6560.1 g C m^-2 a^-1). This study implied that the hypothesis of ‘NPP tradeoff’ could support the measuring of regional ecosystem services tradeoffs and the optimization of ecological restoration modes to synergized improve the provisioning and regulating services.
