title: [Diversity of grasshopper community in lac plantation-farmland ecosystem].
abstract: The grasshopper communities in the paddy field, dry land, natural forest, and plantation forest of lac plantation-farmland ecosystem in Lvchun County, Yunnan were investigated by sweep netting. A total of 1426 grasshoppers belonging to 33 species, 22 genena, and 5 families were captured. In the paddy field, dry land, natural forest, and plantation forest of the ecosystem, the species richness S were 16.333, 13.000, 11.000, and 12.000, Margalef index was 2.873, 2.266, 2.335, and 2. 137, Shannon-Wiener index was 2.034, 1.976, 1.982, and 1.488, Simpson index was 0.196, 0.189, 0.174, and 0.323, and Pielou index was 0.728, 0.787, 0.829, 0.599, respectively. This ecosystem had a lower diversity of grasshopper communities, and different land use habitats in the ecosystem had different species component and diversity. In paddy field, grasshopper had a higher diversity than in dry land, but its evenness and stability were moderate; in natural forest, the diversity was high and the stability was strong; while in plantation forest, the diversity was low and the stability was weak. There existed species exchange in different land use habitats in the ecosystem.
