摘要
对重金属污染与土壤动物多样性的关系进行研究。结果表明,随着污染程度的减轻,土壤动物优势类群、常见类群和稀有类群数量逐渐增加,其中优势类群增加的趋势和幅度明显大于常见类群和稀有类群;各样区的多样性指数和优势度指数也随着污染程度的减轻而增加,但均匀度指数变化不明显。
Relation between heavy metal pollution and soil animal diversity was studied. The results showed that number of soil animal heterotie groups, the common groups and rare species increased gradually with the loss of pollution degree, the trend and magnitude of dominant groups were greater than the common taxa and rare taxa; Diversity and dominance index increased gradually, but the uniformity index change unobvious.
