本研究调查了中国深圳湾福田国家级自然保护区人工种植1、2、7、10和14年生海桑和1、4、7、10和14年生海桑的人工种植林土壤特征、微生物群落结构和功能之间的关系。 7年生海桑林均达到生长高峰，氮磷含量最高，酶活性包括脱氢酶、纤维素酶、磷酸酶、脲酶和β-葡萄糖苷酶，但芳基硫酸酯酶随林龄不断增加。磷脂脂肪酸（PLFA）谱所反映的微生物群落结构也在7年生森林中达到最大值，并且两片森林中土壤细菌PLFA均显着高于真菌PLFA。典型相关分析表明，微生物结构变量的差异与其功能变量的差异显着相关，其中土壤酶活性与碳氮含量的相关性最高。
The present study examined the relationships between soil characteristics, microbial community structure and function in the forests artificially planted with exoticSonneratia apetalaat stand ages of 1-, 2-, 7-, 10- and 14-years andSonneratia caseolarisof 1-, 4-, 7-, 10- and 14-years in Futian National Nature Reserve, Shenzhen Bay, China. The 7-years old forests of bothSonneratiaspecies reached peak growth and had the highest content of nitrogen and phosphorus, enzymatic activities, including dehydrogenase, cellulase, phosphatase, urease and ß-glucosidase, except arylsulphatase which increased continuously with stand ages. The microbial community structure reflected by phospholipid fatty acid (PLFA) profiles also reached the maximum value in the 7-years old forests and soil bacterial PLFAs in both forests were significantly higher than fungal PLFAs. The canonical correlation analysis revealed that differences in microbial structural variables were significantly correlated to the differences in their functional variables, and the highest correlation was found between the soil enzymatic activities and the content of carbon and nitrogen.
