【摘要】：共生理论认为异质共生生物在其生存过程中会表现出相互依存的关系。试图将这一论点移植到农业生态经济研究中,用以处理农业生产中生态效益与经济效益之间矛盾的问题。为此,把农业生态经济视为由生态单元与经济单元组成的异质共生体,分析了该共生体的结构与共生模式,并采用Logistic方程与数值模拟方法,探讨农业生态经济共生体的共生机制,揭示共生单元间的演化规律与成长特征。研究表明:共生模式在农业实践上创新应用的主要目标是将共生体从寄生共生模式向互惠共生模式转型,并提出正向转型的激励策略。共生单元的选择必须具有兼容性,共生单元间有明确的共生界面,促使物质、能量和信息的交流,以增加共生体内自由能。共生关系正向发展要遵循共生演进规律,偏利共生模式是演进到互惠共生模式的必经过程。培育互惠共生适存的共生环境对促进共生体演进至关重要。这些研究成果为农业生态经济研究提供一个新范式,并开创一条研究新思路与方法。
[Abstract]:The theory of symbiosis holds that heterogeneous symbiotic organisms will show interdependence in their survival process. This paper attempts to transplant this argument into the study of agro-ecological economy. In order to deal with the contradiction between ecological benefit and economic benefit in agricultural production, the agricultural ecological economy is regarded as a heterogeneous symbiont composed of ecological unit and economic unit, and its structure and symbiotic model are analyzed. Using Logistic equation and numerical simulation method, the symbiotic mechanism of agricultural eco-economic symbiosis was discussed. The research shows that the main goal of the innovative application of symbiotic model in agricultural practice is to transform symbiosis from parasitic symbiotic model to mutually beneficial symbiotic model. The selection of symbiotic units must be compatible, and there should be a clear symbiotic interface between symbiotic units to facilitate the exchange of materials, energy and information. In order to increase the free energy of symbiotic body, the positive development of symbiotic relationship should follow the law of symbiotic evolution. The symbiotic model of partial benefit is the necessary process of evolution to mutual-symbiotic model. It is very important to foster the symbiotic environment of mutual-symbiosis to promote the evolution of symbiont. These research results provide a new paradigm for the study of agro-ecological economy. And to create a new research ideas and methods.
