| Abstract: |
| Based on the crop cultivation systemof Liaocheng Shandong Province the system productivity composition of crop cultivation and benefit were analyzed. The results showed that the land area of grains kept stable relatively and that of vegetables increased rapidly but the land area of cotton and oil plants decreased during 1995～2005．The land use composition gradually changed fromsingle-element structure of grains mainly to binary structure including grains and vegetables. The crop cultivation composition was inclined to be rational．The system productivity of crop cultivation was clearly enhanced and the product productivity of vegetables and economic productivity of cotton were the highest. Except oil plants the production value of vegetable grains and cotton went up distinctly during 1999～2005．Moreover in the sequence of grains vegetables oil plants and cotton the production value decreased gradually. The production value composition of crop cultivation was apt to be balanced. Due to the crop cultivation structure being adjusted and opti mized the systemstability was gradually reinforced and the benefit evidently enhanced. |
