In the pot experiment, seven varieties of halophytes were grown in saline-alkali soil to investigate the responses of microflora and soil enzymes in the rhizosphere. The results showed that compared to the control, the population of bacterial colony (84.8％-95.6％), actinomycetes colony (12.0％-14.5％) and fungi colony (0.5％-1.1％) increased significantly (P<0.05). The population of ammonia bacteria, aerobic cellulose decomposition bacteria in the soil of Vicia sativa L. (201.99％ and 395.49％), Medicago sativa (152.43％ and 319.90％) and Sesbania cannabina (Retz.) Pori (193.14％ and 396.08％) were higher significantly than that of Panicum virgatum L. (49％ and 60％), Sorghum bicolor (L.) Moench (99％ and 210％), Amaranthus hypochondriacus L. (75％ and 36％) and Aneurotepidimu chinense (75％ and 77％) (P<0.05). However, Sorghum bicolor (L.) Moench was evidently higher than Panicum virgatum L., Amaranthus hypochondriacus L. and Aneurotepidimu chinense (P<0.05) in the soil. The population of ammonia bacteria and aerobic cellulose-decomposing bacteria was significantly correlated with the five enzymes (P<0.05), which could improve the microenvironment in saline-alkali soil to accelerate the element cycling and promote the sustainable development of agriculture through cultivating Medicago sativa, Vicia sativa L., Sesbania cannabina (Retz.) Pori and Sorghum bicolor (L.) Moench.
