Analysis of the negative binomial distribution and test of population pattern.

MA Qin-yan.College of Forest Science,Beijing Forestry University,100083,P.R.China.  
Spatial pattern of population is one of the significant issues in population ecology.In this paper,the random,uniform and clumped patterns and their corresponding probability distribution functions,such as positive binomial distribution,Poisson distribution and negative binomial distribution,are described.The connotative essence,establishment of distributional function and parameter estimation of the negative binomial distribution are discussed in detail.Finally,the common indicators for the testing of population patterns and mistakes in their usage are analyzed.
