Simulation of land transfer process based on energy flow model: A case study of Taihang Mountain area in Hebei Province

Aiming at the inability to effectively reveal the mechanism of energy flow in the process of land transfer, this article utilized the land transfer data of Donggaochang Village in Tai-hang Mountains of Hebei Province from 2016 to 2019, and applied the Energy System Language model to simulate and evaluate the process before and after land transfer in Tai-hang Mountains of Hebei Province, and further simulated the system energy change after land transfer based on the land use scenarios and the viewpoint of labor inputs. The energy changes of the system after land transfer were further simulated based on land use scenarios and labor input perspectives. The results showed that: (1) crop biomass, capital and ecological environment were significantly increased after land transfer compared with before land transfer; after 10 years, crop biomass, capital and forest biomass were 12.97 times, 2.10 times and 36.54 times higher than before land transfer respectively; after 50 years, crop biomass, capital and forest biomass were 15.34 times, 4.23 times and 39.22 times higher than before land transfer respectively; after 100 years, crop biomass, capital and forest biomass were 26.79 times, 7.39 times and 66.60 times higher than before land transfer respectively. (2) The effect of the transfer of changing the planting structure was general, but the adjustment of the labor input structure made the biomass and capital of pumpkin after the land transfer showed an inverted U-shaped trend, with the biomass of pumpkin reaching the peak in 24 years and the capital reaching the peak in 48 years. Inputting local labor increased crop biomass by 46.5% and capital by 212%, which was the most significant effect.
