本文選題：農(nóng)業(yè)生態(tài)經(jīng)濟(jì)　切入點(diǎn)：共生理論　出處：《生態(tài)學(xué)報(bào)》2017年20期

【摘要】：共生理論認(rèn)為異質(zhì)共生生物在其生存過(guò)程中會(huì)表現(xiàn)出相互依存的關(guān)系。試圖將這一論點(diǎn)移植到農(nóng)業(yè)生態(tài)經(jīng)濟(jì)研究中,用以處理農(nóng)業(yè)生產(chǎn)中生態(tài)效益與經(jīng)濟(jì)效益之間矛盾的問(wèn)題。為此,把農(nóng)業(yè)生態(tài)經(jīng)濟(jì)視為由生態(tài)單元與經(jīng)濟(jì)單元組成的異質(zhì)共生體,分析了該共生體的結(jié)構(gòu)與共生模式,并采用Logistic方程與數(shù)值模擬方法,探討農(nóng)業(yè)生態(tài)經(jīng)濟(jì)共生體的共生機(jī)制,揭示共生單元間的演化規(guī)律與成長(zhǎng)特征。研究表明:共生模式在農(nóng)業(yè)實(shí)踐上創(chuàng)新應(yīng)用的主要目標(biāo)是將共生體從寄生共生模式向互惠共生模式轉(zhuǎn)型,并提出正向轉(zhuǎn)型的激勵(lì)策略。共生單元的選擇必須具有兼容性,共生單元間有明確的共生界面,促使物質(zhì)、能量和信息的交流,以增加共生體內(nèi)自由能。共生關(guān)系正向發(fā)展要遵循共生演進(jìn)規(guī)律,偏利共生模式是演進(jìn)到互惠共生模式的必經(jīng)過(guò)程。培育互惠共生適存的共生環(huán)境對(duì)促進(jìn)共生體演進(jìn)至關(guān)重要。這些研究成果為農(nóng)業(yè)生態(tài)經(jīng)濟(jì)研究提供一個(gè)新范式,并開創(chuàng)一條研究新思路與方法。
[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.
