摘要
建立种植业粮、经、饲三元结构是促进农业经济增长、增加农民收入的根本措施。根据系统工程生态学原理。采用线性规划、投入产出等定量数学分析方法,对张掖市进行了粮经饲三元种植结构优化战略研究。研究得出:该市粮、经、饲作物高效种植比例为41.1:31.1:27.8;并提出分层次建立该市种植业三元结构的构想,分析了可供开拓的经济、饲料作物的潜在生态位资源以及粮、经、饲结构优化实施的种植模式及其阶段性效益。表4,参5。
According to principles of ecology theory of systematic engineering, this paper applies mathematical quantitative analysis to the strategy study on optimizing the growing structure of grain, forage and industrial crops. It also puts forward to the proposal of founding three-dimension structure of plant industry on the basis of different level. At the same time, this paper deals with the potential resources of forage and industrial crops as well as the excellent plant pattern and its stage ' s efficiency in Zhangye city.
