摘要
Abstract
Atmospheric dry/wet deposition information was collected regularly at sites including greenbelts, waters, roads, worksites and atmosphere in urban area of Shanghai city. The atmospheric deposition flux, depositions of CODCr, TN and TP were measured and their impacts on urban landscape water were calculated and analyzed. The result showed that with only influence of atmospheric dry/wet deposition, for the water of urban landscape with surface water quality values in class V, in depth of 0.5, 1.0, 1.5 and 2.0 meters, the quality may turn into poor level of class V in 28, 54, 83 and 214 days respective. Based on analysis of case study measures were proposed to deal with the influence of atmospheric dry/wet deposition for keeping good quality of water. These conclusions provide references for the maintainance of urban landscape water.关键词
