The forest was characterized with phanerophyte evergreen plants with single-mesophyll-leathery leaves, which reflected the nature of tropical Karst mountainous seasonal rain forest.(2). Community succession was divided into five stages by using Cluster method, PCA method; the succesion stages include herbaceous stage, scrub-shrub stage, small tree stage, arbor stage and climax seasonal rain forest stage.(3). Based on similarity theory, succession sere was constructed with the community similarity equation formed.

In order to find the impact of cloud drift winds on variational data assimilation system and to provide reference for operational forecast of tropical cyclone, firstly errors of water vapor winds and infrared cloud drift winds in different levels have been analyzed in this paper; then, cloud drift winds of geostationary meteorological satellites-GMS 5 have been added in the GRAPES three-dimensional variational data assimilation system with radiosonde data.
