摘要:
湿地洲滩土壤碳、氮、磷是重要的营养元素,其分布特征直接影响湿地生态系统的生产力和生态系统服务功能.通过2014-2017年对鄱阳湖湿地洲滩前缘浅层土壤(0～20 cm)有机碳、全氮、全磷观察实验分析,结果表明:鄱阳湖湿地洲滩前缘浅层土壤有机碳、全氮、全磷的年际变化特征不同,有机碳变化不显著,全氮、全磷变化显著; 浅层土壤有机碳、全磷、全氮的高程梯度变化极显著; 浅层土壤碳氮比、碳磷比年际变化极显著,氮磷比不显著; 浅层土壤碳氮比高程梯度变化不显著,碳磷比、氮磷比的高程梯度变化极显著.浅层土壤氮磷含量较其他
Abstract:
Carbon,nitrogen and phosphorus are important nutrient elements in soil of wetland tideland,and their distribution characteristics directly affect the productivity and ecosystem service function of wetland ecosystem.Based on the observation and analysis of organic carbon,total nitrogen and total phosphorus in surface soil(0～20 cm)of tideland in Poyang Lake wetlands with sampling from 2014 to 2017,the results show that the interannual variation characteristics of organic carbon,total nitrogen and total phosphorus in surface soil in tideland of Poyang Lake wetlands are different.The change of organic carbon is not significant,but the change of total nitrogen and total phosphorus is significant.The changes of organic carbon,total phosphorus and total nitrogen in surface soil are very significant when gradient is various.The interannual changes of C/N ratio and C/P ratio in surface soil are very significant,but the N/P ratio is not significant.The changes of C/N ratio in surface soil is not significant,but the changes of C/P ratio and N/P ratio are very significant when gradient is various.The content of nitrogen and phosphorus is higher than that in other regions,however,the ratio of C/N,C/P and N/P in surface soil are lower than those in other regions in China with interannual changes various gradient changes.The factors that affected carbon,nitrogen and phosphorus in surface soil of tideland in Poyang Lake Wetlands are complicated and perennial.The changes of vegetation cover,flooding time and water quality of Poyang Lake wetlands have influence on the spatial and temporal distribution of soil carbon,nitrogen and phosphorus.
