Abstract: According to the environmental situation and the mode of agricultural production in karst mountain area of guizhou province , the Guiyang wudang dairy was selected as pilot spot to develop ecoagricultural engineering. Through constructing manmade grass field, optimizing structure of cattle herd, adjusting structure of production, 254 familybased farms were built. Furthermore, new energy sources as well as energy flux and material circulation were developed, thus a high effective mode of ecoagricultural engineering was established.
