摘要
借鉴生态位和共生理论,通过Logistic模型构建和相平面法应用,探究农户和龙头企业间不同的共生行为模式和动态演化过程。研究结果表明,(1)农户和龙头企业间最主要的模式分别是寄生共生、竞争共生、独立共生和互惠共生;(2)偏害共生和偏利共生是农户和龙头企业由竞争共生向互惠共生演化中伴随出现的模式;(3)生态位重叠度和阻滞系数的大小决定了演化的方向,只有生态位重叠度大于阻滞系数,双方才向互惠共生演化。
To explore symbiotic behavioral patterns of farmer and dominant enterprise, as well as the dynamic evolution mechanism of different symbiotic behavior patterns, this paper uses the ecological theory and the symbiosis theory, builds logistic model to explore the different symbiosis behavior modes between farmer and dominant enterprise, and uses the phase plane method to analyze the dynamic evolution process of different symbiotic models. The results of research are as follows ： First, there are six symbiosis behavior modes between farmer and dominant enterprise, but the dominant modes are parasitic symbiosis, competitive symbiosis, independent symbiosis and reciprocal symbiosis respectively; Second, amensal- ism symbiosis and commensalism symbiosis are the transition modes when farmers and dominant enterprises develop from competitive symbiosis to independent symbiosis or from independent symbiosis to amensalism symbiosis; Third, the niche o- verlap and block coefficient determine the direction of evolution. When niche overlap is greater than the block coefficient, both sides will evolve into amensalism symbiosis. Conversely, both sides will evolve into parasitic symbiosis.
