| Abstract: | Using the ecological theory and method, plant diversity in grain for green project land in Pianguan was investiga- ted. The research results showed that there were 95 plant species, belonging to 77 genera and 34 families. The height of the plant in grain for green project land was obviously higher than the comparison and the height of the plant in grain for green project land increased 19. 8 cm, 16. 2 cm and 7.0 cm from 2000 to 2002. At the same time, the relative coverage in- creased 47. 6% ,42. 4% and 33. 1% compared with the comparison. The growth of plant in land of grain for green project evidently increased. |
