| 选取盐城5种城市绿地:杨树林、油菜地、苗圃、公园绿地和草坪,于2011年春季开展了大型土壤动物群落的生物多样性研究。结果显示,密度-类群指数(density-group index,DG)、群落复杂性指数(complexity index,C)与Shannon-Wiener指数(H')等α多样性在苗圃、公园绿地和杨树林中均具有较高水平,在草坪和油菜地的大型土壤动物群落生物多样性水平较低,DG指数与C指数显著线性相关(P<0.01,n=5)并对H'有较为一致的校正效果。采用β多样性(Jaccard群落相似性系数)为基础的系统聚类结果认为杨树林、苗圃和公园绿地群落相似,草坪和油菜地群落相似。研究结果认为,大型土壤动物群落的生物多样性与绿地生境特征的复杂程度相关,绿地中树木的分布情况可能是影响大型土壤动物群落生物多样性的重要因素,这可为城市绿地规划设计提供参考。 |
| 英文摘要: |
| The biodiversity of soil macrofauna were surveyed by sampling five quadrats(20 cm×20 cm)in 5 green-lands (poplar wood,rapeseed farm,grassland in park,nursery,and lawn)at Yancheng City in spring,2011. The habitat of poplar,grassland in park and nursery had a higher value of α biodiversity which characterized by density-group index(DG),complexity index(C)and Shannon-Wiener biodiversity index(H'),while habitat of rapeseed farm and lawn had a lower value. A significant linear correlation was found between DG index and C index(P<0.01,n=5). Based on the β biodiversities(Jaccard’s similarity coefficient),we made Hierarchical Cluster analysis and the results of that the soil macrofauna communities can be divided into two groups formed by habitat of poplar,grassland in park,and nursery as one group,rapeseed farm and lawn group as the second group. Our results indicated that the biodiversity of soil macrofauna communities is related to the complexity of habitat characters. The distribution of trees might be an important factor that influenced on the soil macrofauna communities in green-land. The biodiversities variation among different green-lands can provide help in green-lands design in the cities. |
