An analytic hierarchy process (AHP) has been adopted for the establishment of the evaluation system of forestry afforestation in Hunan Province. Taking forest farm resources, construction management, and brand images as the criterion layers, and taking seven such indicators as ecological environment, landscape resources and infrastructure as the factor layers, 35 evaluation indexes including forest coverage, forest stock, mountain landscape and accessibility can be finally determined, with the weight of each index level worked out by constructing judgment matrix. The results show that the weight ranking of the criterion layer is as follows: forest resources(B1=0.597 1), construction management (B2=0.274 3), brand images(B3=0.128 6); the first three indicators of the weight ranking of the factor level are as follows: ecological environment (C1=0.361 6), landscape resources(C2=0.235 5), infrastructure construction(C3=0.164 1); the first five indicators of the weight ranking of the index level are: forest coverage (D1=0.144 1), forest stock volume (D2=0.081 4), mountain landscape (D7=0.075 9), water landscape (D8=0.064 7), PM2.5 (D3=0.052 7). With Suxian Ridge, a state-owned forest farm, our selected target as an empirical test to verify the evaluation system, the results show that the evaluation system can reflect the situation of the forestry afforestation in Hunan Province, thus verifying its feasibility to a certain degree. Ultimately combined with the analysis results, some proposals have been given for the forestry afforestation in Hunan Province.
