%X This paper established an effective eco-agricultural system through eco-function transformation designing.In the system,the mountain tops are cultivated with closed fine tree species,the middle part of the slopes is rotation cropping subsystem of fruit/pasture and/or fruit/herb,the lower and bottom parts of the slopes is a crop-pasture rotation subsystem,and the courtyards of farm households is a closed animal husbandry.A water-saving model of crop-fruit-pasture is established based on water storage and ducting net.A series of techniques are introduced,including integration of fruit-pasture\herb,manure and straw compost,pasture establishment and management,water resource exploitation and water-saving irrigation,and so on.Livestock forms the center of the system,which transforms the crop grain and pasture into manure that in turn enriches soils planted with crops,fruit and pasture,and accelerates material and energy cycling,thereby improves utilization efficiency of the natural resources.
