摘要:
为探讨微生物在红树林湿地生态系统中的作用,采用Biolog-ECO微平板技术分析东寨港红树林土壤微生物功能多样性在不同月份的变化特征. 结果表明:红树林土壤微生物平均颜色变化率(AWCD)值12月份最高,4月份最低. Simpson指数、Shannon-Wiener指数和Pielou指数在2月份差异极显著. 对6类碳源的利用差异显著(P < 0.5),其中12月利用率最高,1月最低. 氨基酸利用率最高,羧酸类利用率最低. 主成分分析(PCA)表明,在31种因子种提取的2个主成分因子,分别可以解释所有方差变量的49.26%和22.26%,碳水化合物和氨基酸类为对PC1和PC2起分异作用的敏感碳源. 红树林生态系统中,土壤微生物功能多样性随着时间尺度的变化而变化. 说明红树林生态系统生物多样性丰富,蕴藏着丰富的微生物资源.

Abstract:
To investigate the functions of microorganisms in mangrove wetland ecosystems, the functional diversity of soil microbes in the Dongzhaigang mangrove forest in different months was investigated using the Biolog-ECO Microplate. The results showed that the highest AWCD value for mangrove soil microbes was observed during December, and the lowest during April. Simpson’s index, Shannon-Wiener index, and Pielou’s index were highly different in February than in the other months. The utilization of six types of carbon sources differed significantly (P < 0.5) among months, with the highest in December and the lowest in January. The highest rate of carbon source utilization was for amino acids, and the lowest was for carboxylic acids. Principal component analysis (PCA) identified two factors related to carbon sources, representing 49.25% and 22.26% of the variation. Carbohydrates and amino acids were the major sensitive carbon sources for the two principal component factors. In the mangrove ecosystem, the functional diversity of soil microbes varies with time, indicating that the mangrove ecosystem is rich in biodiversity, and contains abundant microbial resources.
