Analysis of Relative Resource Carrying Capacity to Major Grain Producing Areas of Central Jilin

The article compared with the relative carrying capacity of resources in major grain producing areas of Jilin, it was helpful for guiding labour force and agricultural economy. The paper adopted the geometry model of relative resource carrying capacity, the analysis of relative resource carrying capacity in major grain producing areas of Jilin could be calculated from 1989 to 2008. The results showed that the population and economic carrying capacity in major grain producing areas were double abundance from 1989 to 2000, the development of economy was not enough; the population carrying capacity was margin but the economic carrying capacity was overload from 2001 to 2008. The contribution to the synthetic carrying capacity of land and water were greater, the economic carrying capacity increased. Compared with the Shandong, Henan which were major grain producing areas of China, both population and economic carrying capacity were margin, the population carrying capacity was abundance contrast for Heilongjiang. The relative carrying capacity showed the fluctuate variety with the change of time-series.
