The community structure and seasonal change of soil macrofauna in abandoned land of Mianyang City were studied by hand sorting soil macrofauna to probe the soil health condition under different utilization patterns.Soil macrofauna was identified according to Pictorial keys to Soil Animals of China.Results:There are 98 soil macrofauna individuals belonging to 13 species.Myrmicinae is the dominant species in four seasons.Geophilidae,Secernentea,Araneomorphae and Xylophagidae larvae are dominant species in some seasons.Other 8 species are common species.The number of species and individuals of soil macrofauna in abandoned land decreases with increase of soil depth and has the obvious surface aggregation phenomenon (P 0.05).The Shannon-wiener diversity index (H′)and Pielou evenness index (J )of soil macrofauna community both are autumn>summer>winter> spring.The Simpson index(C)of soil macrofauna community is autumn< summer展开▼
