| Abstract: |
| Through analyzing the statistic data of Shijiazhuang area from 1986 to 2000, it is discovered that the area of cultivated land has been descending, the population amount has been rising, and per capita cultivated land has been decreasing constantly. There exist differences among various counties, i.e., the further is the distance of a region from the urban district, the lower is the change rate of cultivated land area. The change of cultivated land and population in next 15 years is predicted by using the Grey Theory. |
