该研究对"四位一体"生态农业模式的结构、功能和效益进行了综合分析。结果表明,采用该模式将种植业、养殖业,生产和生活进行了很好的结合,既解决了沼气发酵原料,净化了环境,又提供了丰富的有机肥料,在有限的土地上,科学、高效地利用时间、空间等资源,实现了能源生态系统中物流和能流的良性循环,达到了能源、生态、经济与社会效益的统一。一个面积为350m2的"四位一体"温室大棚(养殖业、种植业)总的年纯利比普通农户的增加了1倍,同时该模式的采用有效地解决了农村剩余劳动力问题,这种模式的推广应用可产生良好的生态、经济、社会效益。
This study conducts comprehensive analysis on the structure, function and benefit of the'Four in One' ecological agriculture mode. The result indicates this mode well combines plantation, animal husband-ry, production and daily life. It not only provides ferment material for marsh gas, clean the environment, but also provides rich organic manure. It can utilize time, space etc. resources with high efficiency on lim-ited land and realize the fine circulation between matter and energy within the ecological system of energy source, thus unifies the energy source, ecology, economy and social benefit. The total annual net income of a green house of'Four in One" with areas 350cm x 2 is 2 times of that by an ordinary farm household. This mode effectively solves the problem surplus labor force in rural areas. Extension of this mode can pro-duce good ecological, economical and social benefit.
