| 摘要: |
| 从农业系统生产力的角度,探讨桥头乡在实施生态农业规划前后的农业系统生产力及其系统特性结果表明,经过4年多的生态农业规划实施,桥头乡农业系统生产力指数达到87.007×1012J·元/hm2,比实施前的8.748×1012J·元/hm2,增加8.95倍,系统持续性达21.346,比实施前增加8.89倍,系统稳定性为0.972,达显著水平。农、林、牧、渔子系统的生产力指数分别比实施前增加1.51倍,10.78倍,1.07倍和0.46倍。 |

| Abstract: |
| The agrosystem productivities and characteristics before and after carrying out the program of ecological agriculture in Qiaotou Township was studied. The results show that after more than 4 years that the program have been carried out, the agrosystem productvity index reaches 87.007×1012 J. Yuan. (hm2)-1 and 8.95 times more than that 8.748×1012 J. Yuan ·(hm2)-1 before the implement of the program; the agrosystem sustainability reaches 21.346,and 8.89 times more than that before the implement of the program; the agrosystem stability is 0.977. The agrosystem productivity indexes of the sub-agrosystems, farming, forestry, raise stock and fishery increaes 1.51, 10.78, 1.07 and 0.46 times respectively than before carrying out the program. |
