摘要
The researches on species diversity and its relationship with spatial scale have remained a key topic in plant ecology.The results of researches on species diversity are always influenced by sampling strategy.In this paper,the modifiable areal unit problem(MAUP)of species diversity in natural secondary Alniphyllum fortunei forest in Meihuashan Natural Reserve was studied.The results showed that there were scale effect and zoning effect for species diversity in Alniphyllum fortunei community.With the increase of the sample area,the scale effect and zoning effect might decrease.Jackknifing method was able to estimate a normal distribution range of species diversity as well as the zoning effect range.
The researches on species diversity and its relationship with spatial scale have remained a key topic in plant ecology. The results of researches on species diversity are always influenced by sampling Strategy. In this paper, the modifiable areal unit problem （MAUP） of species diversity in natural secondary Alniphyllum fortunei forest in Meihuashan Natural Reserve was studied. The results showed that there were scale effect and zoning effect for species diversity in Alniphyllumfortunei community. With the increase of the sample area, the scale effect and zoning effect might decrease. Jackknifing method was able to estimate a normal distribution range of species diversity as well as the zoning effect range.
