- Title:
- Study on the Holding Potentiality of Land From Grass and Livestock to Supply Grain in Shanxi Province
- Keywords:

- 摘要:
- 黄河中、上游退耕还林还草粮食问题是一项重要的研究内容,它直接牵涉到退耕还林还草的速度问题和恢复生态环境的持续问题.在假定某些条件下,从山西省草地资源最大利用的角度,通过以草养畜,以畜济粮的目标途径,最大限度地估算了山西省(山西省黄河流域)草地资源(包括退耕后还草)的粮食人口承载量,为退耕还林还草解决粮食问题的"生态移民"措施的选择,提供了科学依据.
- Abstract:
- Study on converting farmland to forest and grassland in Yellow river upstream and midstream is one of the most important research work,which relates to converting farmland to forest and grassland and the problem of recovering ecological environment and sustainable development.Based on some hypothesis and from the angle of maximum use of Shanxi Province grassland resource and through the way of raising livestock with grass to supply grain,its grassland resource(including converting farmland to grassland) and bearing capacity of population fed on grain are estimated maximumly.It provides scientific base for solving the problem of converting farmland to forest and grassland and ecological migration.
