The influence of different forage planting model in red soil hills on soil and water conservation and environments was studied. The results with three years research showed that planting forage could reduce significantly runoff and soil loss, intercept rain water, enhance soil moisture content, decrease soil surface temperature in hot period, enhance soil organic matter content thus improve soil fertility. However, planting warm season grass in terraced orchard will affect fruit growth in hot and dry season. Forages in orchard should be legume species with shallow root system such as Lotononis or cool season species that is dormant in summer. Planting forage on terrace ridge of crop plot had little effect on controlling soil and water loss, contrarily it resulted in competition with crop and reduced area planted crop thus reduced yield, so it is not befitting.
