摘要
设计了江西省萍乡市兰坡村“猪-沼-粮”循环经济系统工程的流率入树模型,并利用流率入树枝向量行列式算法得到了系统的反馈环,在反馈环基础上,构造了系统增长基模,得到结论,以沼气工程(沼肥)为纽带,发展养殖业能实现生猪养殖、稻谷种植和蔬菜种植之间的良性循环,能够达到稻谷增产和收入增长,在微观层面上实现粮食安全和农民增收双赢。
The rate variable in- tree model of jiangxi pingxiang lanpocun cyclical economy of ＂pig- gas- food＂ was designed, and the feedback of system was obtained based on rate variable in - tree branch vector determinant algorithm, and system base model was make up. The coordination of the pig breed, plant paddy and plant vegetables will result in raise of paddy and raise of income.
