Abstract: The tri-dimensional eco-agriculture in Guohua Demonstration Area comprises“foodstuff crop-economic crop-pasture” pattern,“fruit-herb” pattern and “ecological forest-pasture-livestock and poultry” pattern. These three eco-agriculture patterns make the most use of light, heat, water and soil in the peak-cluster depressions of Guohua. Analysis of a four-year tri-dimensional eco-agriculture pattern shows that the system greatly improves the ecological environment of Guohua Demonstration Area, vegetation coverage rate increases to 50% ～ 70％ in 2005 from 10% in 2000. Annual net income of farmers rises from 632 yuan to 1 524 yuan in 2005. The tri-dimensional eco-agriculture greatly emphasizes on mutual beneficiality between the environment and economy when compared to traditional agriculture.
