Orchids are generally known to the public as ornamental plants. Soil orchids are orchids whose roots develop entirely in the soil or include plants (terrestrial). This study aims to determine the diversity of soil orchid species and the level of diversity and evenness of species. The research was conducted from April and June, in the forest area of Lore Lindu National Park, Mataue Village, Kulawi District, Sigi Regency, using purposive sampling method by plotting 20 x 20 meters and using descriptive data analysis. Based on the research results of soil orchids found as many as 8 genera consisting of 10 species. The genera found were Arundina, Arachnis, Coelogyne, Calanthe, Cypripedium, Cymbidium, Grammatophyllum, Spathologttis. While the diversity of soil orchid species is classified as moderately abundant, with a species diversity index value (H') of 1.7395 as many as 98 individuals. The highest H' index was Cymbidium sp orchid species, while the lowest index was Coelogyne celebensis J.J.Sm with an H' value of 0.1067 as many as 3 individuals. The evenness index of soil orchid species is high and evenly distributed, with a Species Evenness Index (E) of 0.7554.Keywords: Diversity, Orchid, Specie
