| 摘 要： | 以晋西北偏关县退耕还林地为研究对象,在退耕5,4和3 a(分别为2000年,2001年,2002年)的退耕地分别取120个1 m×1 m的样方,在对照区取24个1 m×1 m的样方,对其进行调查,应用丰富度、多样性指数、均匀度及生态优势度等指标,综合测度物种多样性。结果表明,随着退耕时间的延长,退耕地的物种丰富度、多样性指数逐渐增大,生态优势度逐渐减小,退耕地的物种多样性比撂荒地明显增加。 |

| Abstract: | By using species richness,Shannon-Wiener index,Simpson dominant index and Pielou evenness index,Species diversity study was made in the lands which converted from farmlands to forest or grassland for 3,4 and 5 years in Northwestern Shanxi Province.Research results showed that the species richness and biodiversity index was increased gradually,and the dominant index of them decreased with the elongation of rehabilitation in these converted land.Species diversity of these lands evidently increased. |
| Keywords: | Pianguan County biodiversity biodiversity index converted land |
