- 摘要:
- 退耕还林（草）是恢复和重建生态经济系统，建立可持续发展模式的有效途径，生态经济演变过程划分为三个发展阶段：调整产业结构的初期，土地的合理调整是突破口；稳定发展时期，提高工副业收入、增加单产是其主要驱动力；加速发展时期，以合理安排从土地上解放的劳动力，增加工副业收入为主要发展途径。草地收入水平太低是建立生态经济系统良性循环的制约因素。
- Abstract:
- The project of converting slope cropland to forest and grassland is an effective measure to restore and rebuild eco-economy system, and set up sustaninable development mode.The course of converting slope cropland to forest and grassland can be divided into three stages.The initial stage of modulate the industrial framework, main object is to adjust land using model.Stabe development stage, the most impotent job is to increase the second and the third industry and the yield of each unit.Accelerating development stage, the development focus is to arrange the work force from the countryside.And low income of meadow is a restricting factor.
