Analysis on plant α and β-diversity of wetland eco-system in semi-arid region

Taking α-diversity index(including Shannon-Wiener index,Simpson index, Jsw,and Js which are community evenness indces) and β-diversity index(measured by similarity coefficients),biomass change coefficient as targets this article analyze the stability of plant community under different measures of desertification control in Yanchi County,Ningxia from two criteria about space and time.

Using selected measure methords of α-diversity and β-diversity, the diversity of the species, genus family in this community and their relationship with the environmental conditions were analyzed.

According to field investigation,β-diversity were used for analyze vegetation distribution along the(Geermu-Lhasa section of) Qinghai-Tibetan Railway.

By field investigating of reed community characteristics and acquiring monitoring data, we analyzed the bio-ecological characteristics and β-diversity of reed communities in different environmental grads (mainly based on water depth) of Yellow River Delta with methods of multi-analysis, extremum analysis and β-diversity index analysis.

The paper studys the β-diversity pattern of subalpine meadows in Wutai Mountain with the altitude above sea level by analyzing diversity index in terms of the binary and numerical data,Cody index,Wilson index,Shmida index and Sorenson index,and Bray-Curtis index in term of numerical data.
