Abstract:

The problems of Taylor's power law in examing insect population spatial pattern, were systematically studed. The results were as follows: ①the different combination types of a and b (the parameters in V=am^b), and the law of spatial patterns of insect population were not completely determined by the values of a and b, but by the values of V/m=am^b-1 within the limits [m_a, m_b], the combination types of a and b are nine. ②the parameters of a and b were used for decribing the relation between V and m, none of them do not possess particular bionomics meaning, the b is not the aggregation index to describing insect population inherent charater too. When the sample size in the sampling quadrat are changed, and X_ij'/X_ij≠a, the value of b is certain changed too. ③ when the m≠1, the b=(ar>, or < ) 1-lg(a)/lg(m) can be used to examinig insect population spatial patterns.

Key words: Taylor's model, Live thing population, Spatial pattern
