基于闽东南的资源优势,把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 establish ment 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%and48.4%,and the contents of organic matter in0-20cm soil horizon could increase3.8g /kg and5.5g /kg.The total energy output of unit area of the ecological pattern is5.1time s 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.
