Japonica. Brief speculation on the evolutionary trend of the seed-coat micromorphological features of the genus Kadsura is discussed.Cladistic principles and methods have been employed in this study. The morphological characters have been polarized for phylogenetic analysis. Cladograms have been gotten with the related genus Illicium as the outgroup. As a result, a new system of the genus Kadsura has been reconstructed.

Based on the real observation data, forecast equitation or forecast model, the dynamics method such as divergence and vorticity calculation, real data correction, ascending and subsidence calculation was used to simulate the 4D field of divergence, vorticity and vertical velocity at different time, different range and different levels. The field was connected to 3D fields of insect trajectories, yielding the flying speed, direction, ascending area and subsidence. Thus the peak of immigratory insect could be timely monitored. A system of the peak of immigratory insect forecast was set up.
