Abstract:

Agroforestry and small-scale forests were focused. Huai'an Prefecture, Jiangsu Province is selected as the case study area, stochastic frontier analysis and translog production function were used to analyze the ecological contributions of agroforestry and small-scale forests to agricultural gross production value, farming production value and husbandry production value. The analysis results show that the contributions of agroforestry to agricultural gross production value, farming production value and husbandry production value are negative, while the contributions of small-scale forests to the above are positive, in the meantime, there exist joint production effects among forestry, husbandry and farming, therefore, agroforestry and small-scale forests should be adjusted in order to gain higher ecological and economic returns.

Key words: agroforestry, forest resource in plain area, ecological contribution, stochastic frontier analysis, rural economy
