Abstract: Orthopteran diversities of 10 ecosystems were investigated by sweep netting method in dry-hot valley of Yuanmou , Yunnan .349 orthopteran samples including 25 species were collected .Among them , Acridoidea was the most abundant , with 19 species occupying 76.0 % of the total species .Punica granatum plantation was richest in species , while Dodonaea angustifolia-Heteropogonetea contortus scrub and grass clump were poorest in species by species richness S and Margalef index .The maximum of Shannon-Wiener diversity index was found in the Punica granatum plantation , and the minimum was in the scrub and grass clump .The Orthopterans diversity was lower in Pinus yunnanensis plantation and the scrub and grass clump by Shannon-Wiener index , Simpson index , Pielou index and Atatalo index .With diversity ranking using Patil and Taillies right-tail-sum method , the diversity of many sample communities couldnt be compared with each other .The diversity in the Punica granatum plantation was higher than others except the Mangifera indica plantation , and the diversity was lowest in Pinus yunnanensis forest and the scrub and grass clump .Azadirachta indica-Schleichera oleosa plantation and Punica granatum plantation had the greatest similarity coefficient showed by Jaccard indices , The smallest similarity coefficient was found in Pinus yunnanensis plantation and Pinus yunnanensis-Quercus forest .Dimocarpus longan plantation and Punica granatum plantation had the greatest , while Pinus yunnanensis-Quercus forest and the scrub and grass clump had the smallest similarity coefficient showed by Morista-Horn indices .Jaccard indices were more efficient than Morista-Horn indices in this study .The Orthopterans communities in the 10 sample plots were divided into 5 types using cluster analysis .The habitat of Pinus yunnanensis-Quercus forest was stable .Through more than 30 years' restoration, Pinus yunnanensis-Quercus forest was relative stable .Azadirachta indica-Dodonaea angustifolia plantation was becoming stable after 5 years' restoration .Others were not stable .The scrub and grass clump were degraded , and their vegetation needed to be restored [ Ch , 2 fig .4 tab .22 ref .]
