闽北果园生态系统大气氮湿沉降研究
Study on Wet Deposition of Atmospheric Nitrogen in Orchard Ecosystem of Northern Fujian
摘要
Abstract
The wet - deposition concentration and amount of atmospheric nitrogen in the orchard ecosystem of northern Fujian province were studied from May, 2011 to February, 2012. The results indicated that the average concentration of total nitrogen (TN) , total inorganic nitrogen (TIN) , dissolved organic nitrogen ( DON) , ammonium nitrogen ( NH4 - N) and nitrate nitrogen ( NO3 -N ) in the rainwater during monitoring was 2.11, 1. 07, 1.04, 0. 65 and 0.42 mg/L, respectively. The amount of nitrogen wet - deposition had an obvious seasonal change, and it was high in spring and summer, low in autumn and winter. Annual TN wet - deposition amount was 23. 19 kg/hm2 , and the annual wet - deposition amount of NH4 + - N, NO3 - N and DON accounted for 30. 60% , 20.02% and 49. 38% of the annual TN wet -deposition amount, respectively.关键词
