The invention provides a comprehensive method for utilizing fruit trees, pastures and livestock on the deteriorated mountain lands at the dry and hot valley of Jinsha River, pertaining to the field of forestry, pasture and livestock. The method includes 8 steps, i.e. species selection, seedling raising, preparation of interplanting land, interplanting, care and protection, collection of fruits and legumens, cradling column flowers to feed goats and as well as stable-breeding and semi-stable-breeding of goats. The species select tamarind, column flower/grass and goat; by seedling raising, rational thick-planting, bottom dressing, top dressing, dry-season irrigation, feeding goats with column flower and grass, stable-breeding and semi-stable-breeding of goats, the total nitrogen of 0-20cm soil stratum of the planting area with 2 years of interplanting is increased by 0.025 percent, the organic substance is increased by 0.29 percent, the beneficial self-cycle of water and nutrition is achieved, and the cost is reduced; after 2 years of interplanting, the column flower and grass are used to feed goats, the income of the first year increases by RMB 7050-11150/hectare and the income of the second year increases by RMB 17850-26050/hectare; in addition, the harmonious development of the forestry, pasture and livestock and the improvement of deteriorated mountain lands at the dry and hot valley of Jinsha River are ensured.
