- 摘要:
- 通过对神府-东胜上湾煤矿塌陷区与未塌陷区植物分布情况的调查,利用重要值、生活型、多样性指数等指标分析了未塌陷区与不同塌陷年限区域的植被组成特征,以期为该矿区生态环境恢复提供理论依据与数据支撑;进一步为生态脆弱区植被恢复建设提供参考依据。结果表明:该区共有植物64种,分属20科51属,其中以菊科、禾本科、豆科和藜科占优势,分别为17、10、10、4种;未塌陷区植物以多年生草本和半灌木占优势,塌陷区植被主要以多年生草本和一二年生草本植物为主,沙生和旱生植物有所增加,并出现了超旱生植物;整个采煤塌陷区仍处于植被恢复初期,效果并不明显,甚至部分区域有退化趋势。
- Abstract:
- The plant community constitute characteristic with various periods since subsidence with areas were studied and analyzed which having no subsidence on Shenfu-Dongsheng Shangwan mine by importance value,life form and species diversity.The results showed that there were 64 species which belonged to 51 genera and 20 families in this region.And Compositae,Gramineae,Leguminosae and Chenopodiaceae enjoyed the species advantage as well as it had 17,10,10 and 4 species,respectively.The areas no subsidence enjoyed the perennial herb and subshrub′s advantage.And subsidence area advantage species with perennial herb and annual or biennial herbs,meanwhile,it appeard psammophytes and erophytes even super-erophytes.The all coal mining subsidence area was still in a vegetation restoration early period,the effect was not obvious,even parts of region had a tendency to degeneration.
