Title: Research on Bio-diversity of Artificial and Natural Plant Communities in Loess Hilly Region ——Taking Ansai County As an Example
Abstract: According to the research on the natural and artificial communities by four indexes of species diversity in loess hilly region (Ansai), the purpose is to discuss the relationship between re-vegetation manner and species diversity. The results showed that natural plant communities have relatively high index of abundance , species diversity and evenness especially in third stage of succession;the species diversity and abundance index of artificial bush communities was higher than artificial grass communities,but evenness index was lower than that of grass communities;also,the species diversity and abundance index of natural plant communities was higher than artificial plant communities,at the same time,it has lower abundance index than that of artificial plant communities.
