| 针对西部实施退耕还林还草工程中存在的重林轻草现象，结合甘肃省及其不同类型区的自然条件，运用生态学原理及相关理论对甘肃省实施退耕还草工程的必要性、可行性进行了深入探讨，认为甘肃省应以还草为主、还林为辅，在有还林潜力的地方还应坚持“还草—还灌—还林”的逆向治理路线。 |

| To counter the idea of regarding forest restoration from cropland as superior to grassland restoration from cropland in western area of China,and combine with the natural condition of different regions in Gansu province,the author apply ecological theory and its relevant theories to investigate deeply about necessity and feasibility of the project of grassland restoration from cropland.Finally,the idea of grassland restoration from cropland must be taken as the key link while forest restoration from cropland as subsidiary is get.Moreover,in the regions which have latent potentialities of forest restoration from cropland,the principle that "first is grassland restoration from cropland,then is shrub,last is forest restoration from cropland" should be adhered to. |
