观光农业、农业生产与资金投入的非线性动力学关系——以南京市丹阳镇七仙山玫瑰园为例

Dynamics Relation of Sight-seeing Agriculture, Agriculture Production and Fund Input——Make an Example of Qixianshan Rose Garden in Nanjing City

该文以南京江宁区丹阳镇七仙山玫瑰园为例,建立观光农业、农业生产与资金投入的非线性动力学模式,讨论观光农业、农业生产系统的稳定性问题,研究结果表明:观光农业、农业生产与资金投入三者之间的关系是一种非常复杂的非线性关系,盲目、不切实际的农业生产投资将减小观光农业的规模,而提高农业生产资源的使用价值,将有助于观光农业的发展;在低效率使用农业生产资源的情况下,盲目增加农业生产投入,对农业生产的再扩大和该地区观光农业的发展都是不利的;只有在提高观光农业资源的使用效率和降低农业生产的平均单位投资的前提下,才有可能达到增加农业生产的投入后获得优化该地区的农业生产结构和扩大观光农业规模的目的。

This paper sets up nonlinear kinetics mode of sight-seeing agriculture, agriculture production and fund input and discusses the stability of the system, which includes sight-seeing agriculture and agriculture production. The result of study shows:The relation of sight-seeing agriculture, agriculture production and fund input is a very complicated nonlinear relation. Blind investment of agriculture production will make the sight-seeing agriculture scale small. While improving the use of agricultural resources of production will contribute to the development of sight-seeing agriculture. In case of using agricultural resources inefficiently, increasing the input of agricultural production blindly is unfavorable to the enlargement of agriculture production and the development of sight-seeing agriculture of this area. Only on the premise of improving the use efficiency of sight-seeing agricultural resources and reducing the average unit investment of agriculture production at the same time, it is possible to achieve the goal of optimize the agricultural production structure in this area and expand the scale of sight-seeing agriculture after increasing the agricultural production scale.
