Firstly, according to the distribution theory of the roots of the characteristic equation, the existence and stability conditions of the positive equilibrium point are obtained, and the global stability of the system is proved by using the Bendixson\u2013Dulac theorem. Secondly, we select the fire factor as the control parameter, and obtain the critical value of Turing bifurcation and the conditions of Turing pattern. Then, we derive the amplitude equation near the Turing bifurcation point by using the standard multiscale analysis method. Finally, we do a sensitivity analysis on the tree-grass system with the fire factor, and then a series of numerical simulations based on these analysis results are carried out to verify our theoretical analysis and Turing pattern structure, which is consistent with the biological significance of the tree-grass model. <\/jats:p>","DOI":"10.1142\/s0218127422500511","type":"journal-article","created":{"date-parts":[[2022,3,31]],"date-time":"2022-03-31T09:37:34Z","timestamp":1648719454000},"source":"Crossref","is-referenced-by-count":11,"title":["Pattern Dynamical Behaviors of One Type of Tree-Grass Model with Cross-Diffusion"],"prefix":"10.1142","volume":"32","author":[{"given":"Rina","family":"Su","sequence":"first","affiliation":[{"name":"College of Mechanical and Electrica, Northeast Forestry University, Harbin 150040, P.
