- Abstract:
- Species diversity in riparian groundwater characteristics were analyzed in middle and lower reaches of the Shiyang River by selecting the species richness index, Shannon-Weiner index, evenness index and Simpson dominance index, and according to the data covering 11 groundwater observation wells and plant samples of eight sampling plots in Shiyang River. The results showed that species diversity and ground water depth had a significant correlation with the groundwater depth increases, the species richness and diversity showed a decreasing trend in the middle and lower reaches of Shiyang River, reflecting moisture is the main factors impacting distribution and survival of vegetation, the declining water table and soil moisture content significantly loss were dominant factors causing changes in vegetation diversity of lower reaches of Shiyang River.
