The estimation of species richness at different altitudes on the northern slope of Changbai Mountain

Abstract

By the method of gradient pattern analysis, 24 plots were set at altitudes 700–2600 m with an interval of 100 m on the northern slope of Changbai Mountains. Two non-parametric estimating methods, jackknife and bootstrap, were used to estimate the numbers of species in the communities at different altitudes. Results showed that the estimated numbers of species from bootstrap were more close to the reality. By comparing the difference between estimated number of species and the number of observed species, rationality of critical sampling area for different communities were validated.
