Abstract: The agriculture, forestry and livestock in Minquan County of Henan province were integrated as a whole eco-system in present study. By means of systematic sampling and random sampling, interview with farmers and investigation in overall and in sites, the relationship among forestry, agriculture and livestock in Minquan County was analysed. Fuelwood provided 2.6944 months of family fuel energy with 86.4 kg of average fuelwood consumption per capital and 6.1673?10107kg in total. The foliage from the trees was amounted to 1.385?10107kg, up to 21.95% of the total coarse foliage. The biomass of organic fertilizer from the trees was amounted to 1.761?10107kg, up to 9.34% of the total. The results indicate that forestry in plain area is essential not only for the structure of plain agriculture system but also for the function of the ecosystem.
