- 摘要:
- 通过对湘中5县不同石漠化类型进行植被调查分析，探讨了湘中地区不同石漠化类型的植被组成和群落特征。结果表明：湘中地区不同等级石漠化类型植物群落结构简单，物种组成比较单一，优势种比较明显，中度石漠化时期出现的乔木树种是石漠化地区乔木群落演替的先锋树种；潜在石漠化地区物种组成明显增加，群落结构比较复杂，具有明显的分层现象。通过树高和胸径进行分析表明，潜在石漠化地区植物群落还处于演替阶段，将向着壳斗科植物为主要建群树种的顶级群落方向演替。
- Abstract:
- Based on investigating and analyzing for the different type of rocky desertification vegetation in five counties of central Hunan，the vegetation composition and community characteristics of different types of rocky desertification were discussed.The results showed that the plant community structure was simple，the species composition was single，and the dominant species was more noticeable in the different rocky desertification of Hunan.Tree species was arbor community succession of rocky desertification area pioneer species at the period of moderate rocky desertification.The species composition increased obviously and the community structure was more complex and it had a obvious stratification in potential rocky desertification area.Through the analysis of tree height and diameter at breast height indicated that the plant community of the potential rocky desertification area was still in the stage of succession，and would be toward the top community with the Fagaceae species as the main construction group.
