The ecological agriculture circulation system integrating agriculture, forestry, animal husbandry, biogas engineering and the greenhouse comprises a tree planting unit, a Chinese herbal medicine planting area, a forage grass planting unit,an animal husbandry unit, the greenhouse, a biogas engineering unit, a biological pesticide production workshop, an organic soilless cultivation nutrient solution production workshop and a microorganism breeding workshop. According to the ecological agriculture circulation system integrating agriculture, forestry, animal husbandry, biogas engineering and the greenhouse, grass and tree planting, animal husbandry and biogas engineering are organically combined, and depend on one another to form the organic ecological agriculture circulation system, so that the agriculture development bottlenecksof the land problems of a very small per capita share of cultivated land in China and large-area land polluted by chemical pesticides and chemical fertilizers and the problem of use of reeds, unusedgrassland and saline and alkaline land are completely overcome once and for all; the biogas industry development bottleneck of the problem of biogas slurry pollution is overcome; the forestry development bottlenecks of the problems of small land area, compensation of farmers and demolition are overcome; and the animal husbandry development bottlenecks of the problem of excrement pollution and theproblems of conflict between grass and livestock and conflict between large-scale breeding and protection of ecological environments are overcome.
