以黄海中山河口近岸海域水动力、污染物输移扩散规律及污染物排放量对附近海域影响为主要研究内容。建立二维水流、水质模型,利用有限体积法离散方程并对中山河口近岸海域的水动力状况及污染物输移扩散规律进行数值模拟;选用COD为主要的污染物指标,模拟计算污染物混合区,然后确定混合区内相对不利的3个敏感点,应用统计学原理,统计混合区近岸边缘污染物访问几率。
以黃海中山河口近岸海域水動力、汙染物輸移擴散規律及汙染物排放量對附近海域影響為主要研究內容。建立二維水流、水質模型,利用有限體積法離散方程併對中山河口近岸海域的水動力狀況及汙染物輸移擴散規律進行數值模擬;選用COD為主要的汙染物指標,模擬計算汙染物混閤區,然後確定混閤區內相對不利的3箇敏感點,應用統計學原理,統計混閤區近岸邊緣汙染物訪問幾率。

The main content of the article is hydrodynamics, transport and diffusion of pollutants and pollutant emissions affect to the nearby waters of Zhongshan estuarine coastal waters in the Yellow Sea. Two-dimensional hydrodynamic and water quality model is established. It uses the finite volume dissociated equations to simulate the hydrodynamic characteristic and pollutant transport and dispersion rule about near shore area of Zhongshan estuary. It chooses COD as the main pollutant index to simulate pollutants mixing area, and then ensures three relative disadvantage sensitive points in the mixing zone. Pollutant access probability of mixing zones is analysed by statistics theory.
