山西省草地资源人口承载量研究

为了在黄河中、上游地区加快实施中央“退耕还林还草恢复生态环境”的决策,正确估算区域人口的承载量是一项基础性的研究工作。以山西省和山西省黄河流域为研究区域,利用相关统计、试验数据,设计不同草地利用率层次和不同肉食消费水平等次,对山西省和山西省黄河流域及其各县市草地资源人口承载量进行了单项和组合型的动态变化研究,为山西省区域退耕还林还草和生态移民工作提供了理论基础。

Population Bearing Capacity of Grassland Resource in Shanxi Province

In order to rapidly execute the central government decision that converting farmland to forest and grassland,and recovering ecological environment,estimating population bearing capacity correctly becomes one of the basic research work.Taking Shanxi Province(or Shanxi Province Yellow River watershed) as the studying region,using correlated statistic and test data,establishing different hierarchical structure of grassland utilization ratio and different class of meat-eating consumption level,the population bearing capacity of grassland resource of Shanxi Province and its included counties and cities are study dynamically through single entry and component types.In conclusion,it could provide theoretical basis for converting farmland to forest and grassland and the ecological migration of Shanxi Province.
