Abstract:The soil sample of different vegetation restoration practices were surveyed from September in 2007 to August in 2008 in Shimenshan in Dalian. The nematodes were collected from the soil using elutriate-sieving-shallow pan method. The species richness, abundance, diversity index and ecological index were analyzed. A total of 8577 soil nematodes were collected, belonging to 2 classes, 7 orders, 26 families and 43 genera. The individual density was 4.77 inds. per gram dry soil. The results indicated that the number of soil nematode fluctuated significantly with season, the number of soil nematode in autumn is significantly more than that in summer and in spring. Shannon-Wiener index, Pielou index, Margalef index and Trophic diversity index were used in analyzing the diversity of nematode community, ranking Cc＞Pm＞Clc, while Simpson index ranking Pm＞Clc＞Cc. The value of f/b, MI index, PPI index, MMI index, MI2-5 index, SI index and EI index were used in analyzing the characteristics of the functional structure of the nematode communities, ranking Cc＞Pm＞Clc, while PPI/MI value ranking Clc＞Pm＞Cc. It showed that the Clc was disturbed significantly. Soil physical and chemical characters were correlated significantly with the number of nematodes, the number of genera and ecological indices. Thus, we conclude that the dynamics of nematodes are an important biological indicator for vegetation restoration.
