Simulation and prediction of the scale change of fungal community. First, using the experimental data of a variety of fungal decomposition activities, a mathematical model of the decomposition rate and the relationship between the bacterial species was established, thereby revealing the internal mechanism of fungal decomposition activity in a complex environment. Second, based on the linear regression method and the principle of biodiversity, a model of fungal decomposition rate was constructed, and it was concluded that the interaction between mycelial elongation and moisture resistance could increase the fungal decomposition rate. Third, the differential equations are used to quantify the competitive relationship between different bacterial species, divide the boundaries of superior and inferior species, and simulate the long-term and short-term evolution trends of the community under the same initial environment. And an empirical analysis is made by taking the sudden change of the atmosphere affecting the evolution of the colony as an example. Finally, starting from summer, combining soil temperature, humidity, and fungal species data in five different environments such as arid and semiarid, a three-dimensional model and RBF neural network are introduced to predict community evolution. The study concluded that under given conditions, different strains are in short-term competition, and in the long-term, mutually beneficial symbiosis. Biodiversity is important for the biological regulation of nature.
真菌群落演替的模拟与预测。首先,利用多种真菌分解活动的实验数据,建立了分解速率与细菌种类之间的数学模型,从而揭示了复杂环境中真菌分解活动的内在机制。其次,基于线性回归方法和生物多样性原理,构建了真菌分解速率模型,得出菌丝伸长和抗湿性之间的相互作用可以提高真菌分解速率的结论。再次,利用微分方程来量化不同细菌种类之间的竞争关系,划分优势和劣势物种的边界,并模拟相同初始环境下群落的长期和短期演化趋势。并以大气突变影响菌落演替为例进行了实证分析。最后,从夏季开始,结合干旱半干旱等五个不同环境中的土壤温度、湿度和真菌物种数据,引入三维模型和 RBF 神经网络对群落演化进行预测。研究得出结论,在给定条件下,不同菌株处于短期竞争,而在长期则是互利共生。生物多样性对于自然的生物调节至关重要。
