Dataset on community composition and diversity changes of soil nematodes along the agricultural ecosystem in Jilin Province, China

This dataset comprises five tables: (1) Sampling site information table include site names, latitude and longitude coordinates, elevation and annual mean precipation and annula mean temperature; (2) Soil nematode community composition table include nematode trophic groups, CP values, family and genus-level taxonomic information and relative abundance; (3) Realtive abundance of nematode trophic groups table include relative abundance of bacterivorous nematodes, fungivorous nematodes, plant-parasitic nematodes, and predatory-omnivorous nematodes; (4) Nematode diversity index table include Shannon-Weiner index, Richness index, Chao's index, Evenness index and Dominance index; (5) nematode ecological indices table include  Enrichment index, Structural index, Total Maturity index, Plant Parasites Maturity index, and Nematode Channel Ratio.
