基于闽东南的资源优势，反发展亚热带水果作为特色农业。由于生态环境脆弱，必须寻求特色农业生产的最佳模式。本研究设计果农草牧复合系统作为特色农业的生态模式。试验表明：生态模式与传统模式相比，泥沙流失量仅是传统模式的26．3％和48．4％，0－20cm土层的有机质含量增加3．8g/kg和5．5g/kg。土地单位面积能量总产出是传统模式的5．1倍。本生态模式显示生产良好循环，取得有效的生态和经济效益，并有很好的的发展前景。 |

The subtropical fruit should be developed as a characteristic agriculture on the basis of resource superiority in southeast Fujian province. Owing to fragile eco-environment, it is nec-essary to seek the best patterns of characteristic agricultural production. The establishment of fruits-farming-grass-stock breeding (FFGS) complex system as an useful ecological pattern of characteristic agriculture is designed. The result of experiment shows that comparing the ecolog-ical pattern with the traditional pattern, the water and soil loss would reduce by about 26.3% and 48.4% , and the contents of organic matter in 0-20cm soil horizon could increase 3.8g/kg and 5.5g/kg. The total energy output of unit area of the ecological pattern is 5.1 times as much as that of the traditional pattern. This ecological pattern shows a benign circulation in the pro-duction, gains favorable ecological and economic benefits and displays good prospects. |
