摘要： “猪—沼—果”生态农业模式是一种循环经济模式,论文分析了这一模式的系统结构和运作机制,总结了科学实验的结果。“猪—沼—果”模式以沼气池为核心,聚集了一系列复杂的生化反应,优化传统种养模式的组织结构,使物质充分利用,能量有效转换,具有显著的经济、社会和生态环境效益。江西建设了103.87×104个农户家用沼气池和250个大、中型沼气工程,每年可以节省木材600×104余m 3,相当于75×104hm2林地的活立木蓄积量;农作物施用沼肥,节省化肥农药,比传统模式提高肥效20%左右。“猪—沼—果”模式在流域综合治理、减少农村面源污染、发展绿色食品和控制血吸虫病等方面都有广泛的应用。

Abstract: The "Pig-Raising,Methane-Generating and Fruit-Growing" eco-agricultural system is a pattern of recycling economy.The system structure and work mechanism are analyzed and results of scientific experiment are summarized for the development of recycling economy in this paper.The system integrates a series of complex biological and chemical reactive process based on the methane-generating.This leads to simultaneous accomplishment of upgrading structural hierarchy for traditional cultivation pattern,making full use of material in multiple hierarchies,making effective conversion of energy,and bringing economic,social and ecological benefits.Some 103.87 million methanegenerating pits and 250 big methane-generating projects have been constructed in Jiangxi Province.Because firewood gathering has been replaced by methane,more than 6×106 m3 of woods are saved every year,and 74×103 ha of forest has been projected.The residues in methane-generating can be returned to farmland,so that fertilizer use efficiency increased by 20% in contrast to the traditional pattern and the soil quality can be improved,for example the organic materials increased by three times and the dissolve nitrogen increased by more than one times.The "Pig-Raising,Methane-Generating and Fruit-Growing" eco-agricultural system has been widely used in tackling small catchment in a comprehensive way,reducing environmental pollution by area source in rural areas,predicting the pollution-free foods and controlling schistosomiais.The results of the theoretical research and scientific experiment show that development of recycling economy should maintain the direction in the theory and methodology of the system science,take the motive force of science and technology as a guidence and laws and policies as a support.
