根据95种不同的单一联底物上的BIOLOGGN微平板系统的反应所构造的多样性指数，结果表明农药严重污染的土壤微生物群落的Shannon指数和均度、Simpson指数、Mclntosh指数和均度均显著低于无污染的对照。说明农药严重污染导致土壤微生物群落功能多样性的下降，减少了能利用有关碳底物的微生物的数量，降低微生物对单一碳底物的利用能力。
Based on the diversity index of the BIOLOGGN microplate system on 95 different single substrates, the results showed that the Shannon index and the degree of homogeneity, the Simpson index, the Mclntosh index and the average degree of the soil microbial community were significantly contaminated by pesticides Lower than non-polluting controls. It indicates that the heavy pollution of pesticides leads to the decline of functional diversity of soil microbial communities, the decrease of the number of microorganisms that can use carbon-related substrates and the reduction of microbial use of single-carbon substrates.
