Plant parasitic nematodes with various populations have found in the soil around the roots of plants. Due to the biologic value of landscape and the importance of plant parasitic nematodes in the reduction of the growth of landscape plants; the study of identification, abundance and distribution of plant-parasitic nematodes in landscape of Tehran city, Iran was in interest. In order to dentification of plant parasitic nematodes, 150 samples of rhizosphere of lawn and a variety of ornamental plants were collected in September and October 2013 from different landscapes in Tehran city. Soil samples were washed and nematodes were extracted, fixed, transferred to glycerin and slides were prepared. Morphological and morphometrical characters of the nematodes were evaluated microscopically according to references. As a result were identified 28 nematode species belonging to 19 genera. The genera Filenchus, Criconemoides, Helicotylenchus, Pratylenchus and Criconema had the greatest diversity of species in the examined materials. Among surveyed species, the most abundant were Helicotylenchus pseudorobustus, Filenchus afghanicus and Aphelenchus avenae by 57.3, 50.7 and 49.3 percent, respectively.
