By using phospholipid fatty acids (PLFA) method, this paper studied the soil microbial community structure in the soybean fields with different chlorimuron-ethyl application history in Weihe district of Heilongjiang Province. In the meantime, the residual amount of chlorimuron-ethyl in soil was determined. There was a very low residual of chlorimuron-ethyl in soil under the conditions of different chlorimuron-ethyl application history. With the increasing year of chlorimuron-ethyl application, the total concentration of soil microbial PLFA and the ratios of fungi/bacteria and Gram negative/Gram positive bacteria decreased, and the microbial stress level increased. Principal component analysis (PCA) showed that long-term application of chlorimuron-ethyl into soybean field changed the soil microbial community structure significantly.
采用磷脂脂肪酸（PLFA）方法，研究了黑龙江省渭河区不同氯嘧磺隆施用历史的大豆田土壤微生物群落结构。同时，测定了土壤中氯嘧磺隆的残留量。在不同氯嘧磺隆施用历史条件下，土壤中氯嘧磺隆残留量极低。随着氯嘧磺隆施用年限的增加，土壤微生物PLFA总浓度、真菌/细菌和革兰氏阴性菌/革兰氏阳性菌的比例降低，微生物胁迫水平升高。主成分分析（PCA）表明，长期在大豆田施用氯嘧磺隆显著改变了土壤微生物群落结构。
