The AA. investigated the effects of long-term (19 years) land use and fertilization on soil microbial community structures in a Luvisol soil, located in Shenyang, Liaoning province. The experiment involved several cropping treatments and no-crop treatments. The biomass and community composition of microbes in this soil were analyzed by phospholipid fatty acid (PLFA) and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) approaches. The results showed that the microbial PLFA concentrations were significantly affected by different land use types, and decreased in the order of non-mowed fallow > mowed fallow > four cropping treatments > bare land. It is concluded that different land use types exerted greater impacts on soil microbial biomass and community structures than fertilization regimes in the Luvisol soil. Moreover, the changes of microbial biomass and community structures mainly resulted from differences in soil total C and N contents
