| 中文摘要: |
| 以聊城市种植业系统为研究对象,对系统生产力、种植业结构与效益进行了动态分析。结果表明:1995~2005年,粮食作物面积保持稳定,蔬菜面积快速增加,棉花和油料面积有所减少,种植业结构逐渐由以粮食为主的一元结构逐渐转变为以粮食、蔬菜为主的二元结构,种植业用地结构渐趋合理;种植业系统生产力明显提高,其中蔬菜产品生产力最高,棉花经济生产力最高;种植业产值明显增加(油料作物除外),其中蔬菜产值最高,粮食作物次之,油料和棉花产值较低,产值结构趋于平衡。由于种植结构的不断调整优化,系统稳定性在调查年度内有所增强,生产效益明显提高。 |
| 英文摘要: |
| 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. |
