摘  要:
采用"生产力衰减法"估算了沅陵县主要粮食作物生产潜力,在此基础上分析该县的粮食安全状况。结果表明,沅陵县主要粮食作物生产潜力指数为57.25%,尚有一半以上的生产潜力有待开发。在人均粮食消费400 kg的标准下,沅陵县的土地资源人口承载力为56.60万人,低于实际人口量,存在粮食安全问题。因此,必须深入挖掘该县粮食生产潜力,提高粮食单产,并控制人口增长。

摘  要:
The potential productivity of main grains in Yuanling County was estimated by using environmental elements step up method,and based on its results,the food security situation in Yuanling County was analyzed.The results showed that the potential grain productivity index in Yuanling County is 57.25%,which has more than half of grain productivity can be developed.At the current level of grain consumption per capita(400 kg),the land resource in Yuanling County can bear only 566 000 people,which is lower than actual population.To ensure food security,the grain productivity should be improved and the rate of population growth should be controlled.
