摘  要:
选取了邻近的3种林龄(10、20和30年)的柑橘(Citrus reticulata Blanco.)凋落物和土壤作为研究对象,研究其碳氮磷化学生态计量特征,了解三峡库区柑橘园生态系统的碳氮磷分布格局及其生态化学计量特征。结果表明,碳氮磷含量均表现为凋落物<土壤。林龄对凋落物碳氮含量、凋落物C/N、土壤C/N和土壤C/P均无显著影响,但是对凋落物磷、土壤碳氮磷、凋落物C/P和N/P以及土壤N/P影响显著。随着柑橘林龄的增大,土壤碳氮磷含量和土壤N/P逐渐提高,而凋落物磷随着柑橘林龄的增大呈现出先提高,20年达到最大值,其后又降低的趋势,凋落物C/P和N/P呈现降低的趋势。

摘  要:
In order to ascertain the distribution patterns of carbon,nitrogen and phosphorus and the ecological stoichiometry in citrus plantation, in this study,the litter and the soils were studied of three forests with near age(10 years, 20 years and 30years) in citrus plantation of the Three Gorges Reservoir area. The results showed that the content of carbon,nitrogen and phosphorus were in the order of litter
