In my opinion, it is necessary to conduct an in-depth discussion on this issue, We should firstly clarify the role and mechanism of the forest theoretically and then make a quantitative analysis and inference when possible.At present the problems are mainly the lack of a solid theory in theory and the lack of demonstration of experimental data in practice so that when the reference On the more exaggerated.
