title: [Interspecific association of companion species in Artemisia annua community in southwest of China].
abstract: The interspecific association of companion species in Artemisia annua community in 48 region of southwest China was analyzed by variance analysis, chi2-test and association indices. The total related variance ratio among species in A. annua community was 2.05. Among 45 species pairs of 10 main species in the community, only 4 pairs showed significant negative correlations. Chi2 test, PC, OI, DI and AC values indicated pairs 1-8 (A. annua- A. lactiflora), 1-9 (A. annua- Setaria viridis) and 1-10 (A. annua- Bidens pilosa) showed a high correlations, and common utilization to non-restrictive resources. The results indicated that there was a significant positive correlation among species,and the community was at a stable stage, showed strong ability to human interference.
