银川市中山公园土壤动物群落多样性研究

[目的]为城市土壤生态系统的健康维持提供重要参考。[方法]在银川市中山公园选择3个样地对土壤动物群落进行初步调查,并将它们与农田、林地等自然状态下的情况进行比较。[结果]中山公园土壤动物受人类活动干扰较大,游人活动多的地方土壤动物数量少,而且在垂直分布上表现出明显的表聚特性,而在季节分布上7、8月份温度较高时土壤动物数量明显减少。[结论]城市土壤有机质层较浅,必要时需添加外来土壤以进行更好的生态和景观建设。

Study on the Species Diversity of Soil Animal in Zhongshan Park of Yinchuan

[Objective] The research aimed to provide important references for the healthy maintenance of urban soil ecosystem.[Method] Three sample plots of Zhongshan Park in Yinchuan were chosen.The preliminary investigation of soil animal communities was carried out,and it was compared with conditions under farmlands and forest lands.[Result] The results indicated that visitors' behavior had influence on the individual numbers of soil animals,and the soil animals reduced along with the increasing soil depth and temperature(in July and August,the temperature was higher).[Conclusion] The organic layer of city soil was sallow,extra soil could be added when it was needed to make ecological and landscape construction.
