长江上游江津段河岸带对陆源氮磷的拦截作用研究
|
Abstract:
2013年1月至2014年1月对长江上游江津段德感坝河岸带进行了1年调查，结果表明，该河岸带能有效拦截来自陆地的氮、磷物质，其中对总氮的拦截率为45.05%，土壤拦截量占87.99%，植被拦截量占12.01%；对总磷的拦截率为20.27%，土壤拦截量占98.40%，植被拦截量占1.60%；不同样带土壤对氮磷的拦截作用有统计学意义.岸坡区样带砂壤土质比近水区样带砂土土质更能有效地富集氮磷元素.
According to a year-long investigation from Jan. 2013 to Jan. 2014 at the Deganba Riparian of Jiangjin in the upper reaches of the Yangtze river, the riparian zone effectively intercepted the nitrogen and phosphorus from the land. The interception efficiency of the riparian to total nitrogen was 45.05%, of which the interception rates of the soil and the plants accounted for 87.99% and 12.01%, respectively. The interception efficiency of the riparian to total phosphorus was 20.27%, of which the interception rates of the soil and the plants acounted for 98.40% and 1.60%, respectively. The soils in different transects of the riparian varied significantly in interception of nitrogen and phosphorus. The soil in the riparian zone, which was sandy loam in texture, enriched nitrogen and phosphorus more effectively than that in the waterfront zone, which was a sandy soil
