According to the phytosociological theories and methods of Braun-Blanquet's school, the regional savanna vegetation of the dry-hot valleys of Yuanjiang river had been investigated. Based on the principle of fidelity degree, the typical 110 releves taken from every sampling stands of the dry-hot valleys were sorted up from below to upper into 15 Associations, then into 5 Alliances, 2 Orders and 1 Class. A synoptic classification system of Class-Order-Alliance-Association was established for the purpose to reflect deeply the characteristics of all syntaxa there in the aspect of plant component and their abundance-dominancy, presence, cover coefficient, life form, growth form, and ecological environment, community structure, species types and so on.

The generic data matrix and database of adult morphology of Tenthredinoidea were set up. The polarization of each morphologic character was concluded based on the evolutionary morphology, the inner group comparision and fossils analysis. The generic cladogram of Tenthredinoidea was calculated by PC586 computer using Hennig86 program. A new classification system for Tenthredinoidea was proposed based on the analysis of the cladogram. The tribal cladistic biogeography of the superfamily was analyzed using Diva program.
