摘要
以汇水区域相对独立的崂山王哥庄地区为例 ,通过研究该区的水文地质条件、分析地表水和地下水中的硝酸盐氮 (NO3 N) ,采用流量法和断面法分别对河流和地下水向王哥庄湾的NO3 N输送量进行了计算。结果表明 ,1999年 5月下旬地下水向海洋输送的NO3 N占整个陆源输入量的 30 .0 6 % ,说明地下水向海洋的营养盐输送量是海洋环境评估的重要边界条件。
Wanggezhuang Bay is a comparatively independent catchment. Hydrogeological conditions were studied and the nitrate concentations of surface waters and groundwater were analyzed. Nitrate fluxes to Wanggezhuang Bay through surface water and groundwater were calculated by flowing calculation and section calculation, respectively. The main conclusions are: groundwater flux of NO 3 N was 30.06% of total terrestrial flux; groundwater flux of nutrients is an important borderline condition for the marine environmental evaluation.
