Abstract: Through exploration of the characteristics of a crop canopy structure and the variation laws in the crop development processes, a three-dimensional crop canopy structure model and a dynamic maize growth simulation are established by fusing the three-dimensional crop canopy structure model. The model describes the crop growth and development stages by adopting growing degree-days, carries out dynamic simulation on a two-dimensional maize canopy structure by adopting a Logistic equation, and characterizes veins, leaf margin and the like by adopting a spatial topological structure. On this basis, a dynamic simulation method for a three-dimensional spatial crop canopy structure is finally established, the coupling simulation of multiple hydrothermal carbonization processes in a complex farmland ecosystem is realized, and thus the simulation capability and universality of the crop model are effectively improved.

Abstract: A redundancy method includes that a first disaster management function (DMF) device on a first site side receives a first request including identification information of a first virtual machine (VM) and a recovery point objective (RPO), allocates a maximum allowable delay time to each node that input/output (IO) data of the first VM passes through in a redundancy process, and sends a second request to a second DMF device on a second site side. The second request includes a maximum allowable delay time of a second replication gateway function (RGF) device on the second site side, and a maximum allowable delay time of an IO writer function (IOWF) device on the second site side and requests the second site side to perform redundancy on the first VM. Hence, the RPO requirements of the tenants can be satisfied in an entire redundancy process.
