研究分析了海南东寨港三种不同生境红树林土壤风干前后肉足虫群落的变化情况,结合环境因子对风干前后肉足虫的现存量、物种多样性进行了对比分析。结果表明:无论是新鲜土样还是风干土样,肉足虫的丰度和多样性指数均呈递增趋势(裸滩〈人工红树林〈天然红树林);此外,在裸滩、人工红树林和天然红树林中,新鲜土样和风干土样的第一优势类群都为变形目(Amoebina);第二优势类群都为表壳目(Arcellinida)。
This paper reported the difference of soil sarcodina community before and after Air-drying in three different lands: naked land without mangrove(NL), land with man-made mangrove(M) and land with natural mangrove(N) in Dongzhaigang Bay in Hainan Island. Results showed that: Both in fresh samples(FS) and dried samples(DS), the standing crops and biodiversity index of sarcodina are trend to increase(NL〈M〈N), and the first dominant species are Amoebina, the second dominant species are Arcellinida both in FS and in DS.
