Abstract:Nine types of forest communities in Dongling Mountain,Beijing,China,were studied with 8 models ,which are logseries (LS),log normal(LN),negative binomial(NB),geometric(GOM),broken stick(BSM),niche preemption(NPM),Zipf(ZM),and Zipf Mandelbrot(ZMM)models.The former 4 belong to species abundance distribution models,and the latter 4 ranked abundance list models.The result shows that most of the communities can be fitted well with LS,NB and ZM.All the communities can be fitted well with ZMM and NPM. The result w...
