Community structure of soil fauna under different land use types in the coastal area of Northern Jiangsu Province
[Objective]Investigate the diversity and ecological distribution of soil fauna in different land-use types in the coastal areas of Northern Jiangsu Province, China, and provide basic data for research on soil fauna systems and assess-ment of ecosystem health in this area.[Method]We analyzed soil fauna in three different land use types (i.e. poplar-crop integrated system, poplar plantation and crop land) from December 2013 to December 2014 in a coastal area in Northern Jiangsu Province, China.[Result]Acarina and Collembola were the dominant Order in this area, and the combined pop-ulation in the two Order accounted for 82.48% of the total number of individuals constituting the body of the soil fauna community in the aforementioned coastal area. The vertical distribution of the number and components of the soil fauna groups had obvious surface collection. Simpson's dominance index was the highest in the crop land, and the Shannon-Wiener diversity and Pielou's evenness indices were the highest in the poplar plantation. Margalef' s abundance index was the highest in the poplar-crop integrated system. The soil fauna in the poplar-crop integrated system was character-ized by the highest number of taxa and individuals and highest Margalef's diversity index value, suggesting that agro-for-estry ecosystems may support greater density and distribution of soil fauna than monoculture or plantation forestry.[Con-clusion]Land use changes may alter species composition and structure of soil fauna assemblage, and moreover, human intervention may affect the diversity and evenness of soil fauna.
