%X The foundation and its adjusting methods of farming-forestry-animal husbandry compound ecosystem in Kaifeng sandy experimental region are analyzed, and the characteristics of the system are stated. The results show that the ability of biological production has been improved, the income per person is getting more and more, and the input of material and energy of field system is getting better and better. However, there still exist the shortage of potassium and the unbalance of production structure. Finally, the experiments and methods of the system development are suggested.
