摘　　要：经十多年的试验研究，在低丘红壤区建立起的生态模式有林业型、食用笋型、林果型、林茶型、旱地作物型、粮草渔畜型。在这几种模式中，以食用笋型经济效益为最高，旱地作物型次之，林业型为最低；而产投比则以林业型为最高，食用笋型次之，林茶型为最低。The experimental results show that there are characteristics on aggravation of climate varation, obvious soil degradation and deterioration of ecosystem succession in ecotone on low-hill red earth. The climate has been become uneven precipitation distriubtion in four seasons every year and the disastrous climates are frequent in this ecotone in the growing season of plants; Soil degradation is characteristics on soil erosion, soil nutrient loss and soil acidity; With the degeneration of vegetation, decreasing of soil nutrients results in regressive successions in red earth ecosystem.
