查询词典 species

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

The total seed storage in topsoil (0-10 cm) was 83499-109141 indm^(-2) for natural wetlands and 9140-47452 indm^(-2) for reclaimed paddy fields. In natural wetlands, the seeds were of 16-30 grass plant species, being dominant with Polygonaceae and Cyperaceae or Cyperaceae and Gramineae; while in reclaimed paddy fields, the seeds were of 7-16 grass plant species, with the dominant of Gramineae. The seed storage and species numbers were greater in Shengjin Lake than in Shibasuo Lake. Higher seed bank storage and more species were observed in the paddy fields from Shibasuo wetland with 30 years of cultivation than from the Shengjin Lake wetland with over 50 years of cultivation.

结果表明：天然湿地种子库密度为83499~109141粒m^(-2)，而开垦为稻田30~50年后种子库密度为9140~47452粒m^(-2)；天然湿地的土壤种子库物种数为16~30种，以蓼科－莎草科或莎草科－蓼科为优势种，开垦为稻田后物种数下降为7~16种，且趋向于以禾本科为单一优势种；此外，与十八索湿地相比，升金湖湿地有较高的土壤种子库物种数、丰富度和多样性，而开垦年限为30年的十八索稻田土壤种子库物种数和丰富度显著高于开垦年限为50年的升金湖稻田。
