摘要
以偏关县退耕还林地为研究对象,应用生态学原理和方法,调查退耕还林地的植物种类。结果表明,偏关县退耕地植物共有34科,77属,95种。2000年,2001年和2002年退耕地的植物高度分别比对照区增加了19.8 cm,16.2 cm,7.0 cm;植被相对盖度分别增加了47.6%,42.4%和33.1%.退耕地的植物生长发育速度比对照区快。
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.
