The study showed that at low elevation of Three Gorges Reservoir area,Pinus massoniana,Cupressus funebris and Cunninghamia lanceolata were the main coniferous forests,which were respectively divided into 14,9 and 5 community types based on field *** whole trend of their species richness index,species diversity index and species evenness index was that shrub layer and herb layer were larger than tree *** diversity indices had no obvious trend along the low elevation gradients,which was probably relevant to the high intensity of human activities in the area.

At present,the progress of the study and application of forest plant disease was impeded by the lack of the internet resources of research achievements and control methods of forest plants *** a forest plant disease information manage system based on internet were *** forest plant disease information website was established on the basis of HTML,ASP,Javascript and Microsoft Access *** sources of the database were Chinese forest plant disease occurred severely in recent decades and the forest plant disease specimen of Chinese Academy of *** website was divided into six basic function modules,including the home page,the research group information,the guestbook,the forest plant disease information management system,the forest plant disease specimen management system and the forest plant disease diagnose *** forest plant disease information could be easily queried and browsed through supported fields with these function ***,the discussions about forest plant disease could be done with the guestbook or *** information and achievements of the research group were also showed through the website.
