| 英文摘要 | Geostatistics was applied to assess the spatial distribution of bacterivorous nematodes in a Chinese Ecosystem Research Network (CERN) site in northeast China. A 42x30 m plot was divided into grids with 7x5 m spacing that included 49 sampling points. Soil samples were collected from depths of 0-10 cm and 10-20 cm. The results showed that Cephalobus and Panagrolaimus were the most dominant bacterivores, which together represented 74 and 82% of total bacterivorous nematodes on average at depths of 0-10 cm and 10-20 cm, respectively. Within-site variability was high for these nematode genera. Geostatistical analysis indicated that a major part of this variability was spatially dependent; variograms suggest that 55-100% of sample population variance was related to spatial autocorrelation over ranges of 9-91 m. The mean numbers of total bacterivores and Panagrolaimus populations were higher at 0-10 cm depth than at 10-20 cm depth. Between the two depths, different distribution patterns were found for Panagrolaimus, whereas similar patterns were found for Cephalobus. The maps obtained by kriging well illustrated horizontal distribution patterns of bacterivorous nematodes at two depths at field scale. |
