In tnts paper,the Nonlinear Age-dependent forest evolution equation is discussed.The existence and uniqueness of the equation are have been proved.Also,we consider the equilibrium solution and nonequilibirium solution for the nonlinear forest systems with constant size,and give the necessary and sufficient conditions for the existence of equilibrium solution and nonequilibrium solution. 展开更多
