In this paper, a new paper formation index-wavelet index (WIn) is put forward when the express of paper formation is combined with the wavelet multi- r esolution analysis(MRA) technology.

The results showed that insect species and number were greatly different at different altitude levels and time,and Diptera,Hymenoptera and Coleoptera were more stable dominant populations in all researched ones;insect dominance indexes were different at different altitude levels and time,but insect diversity indexes were close;evenness indexes were slightly higher at mid.

And the species diversity index (Shannon-Wiener index H′,Simpson index D) ,the richness index (R0,R1),the dominance index (C) and the evenness index (E) were measured in Calligonum L.

Different land use types of vegetation situation in Wufendigou Model of Huangpuchuan watershed were analysed,using diversity index,richness index,evenness index and community structure,respectively.

The algal diversity of four tributaries of Yangtze River was assessed applying the diversity index, richness index and evenness index.

The species diversity index and evenness index are 2.

The main research included the composition of the algae phytoplankton,biological species,biomass,biological indicator,uniformity index,diversity index and physical-chemical monitor,et al.

The differences of advantage,diversity index and uniformity index of insect community in different altitude of Jiangping strict of Huping Mountain were analyzed The lowest index of advantage of insect community was in an altitude of 900m,with a slight increase in elevation.
