Abstract:The grasshoppers’ biodiversities were studied, so as to find out the control countermeasure of harmful grasshoppers. Besides, the structure of grasshoppers’ communities and the similarity were compared and analyzed in different habitats in North Luo River Valley of Yan’an by using methods of diversity indices and similarity analysis. The results showed that the order of diversity indices of different habitats from high to low was: grassland> riverside> shrub > farmland, i.e. the diversity index of grassland was the highest, the farmland was the lowest. Variational trend of Margalef index was the same as Shannon-Wiener index, but the variational trend of Simpson index was opposite. For the analysis of similarity, the similarities of grassland and riverside were very similar, indicating that the two habitats had the similar composition of grasshoppers and more common species, so it could be concluded that the habitat conditions of grassland and riverside had some similarities, whereas farmland and grassland are completely different habitats.
