| 探讨一种基于GIS 克里格插值方法的剩余环境容量计算方法, 通过GIS 地统计分析插值模型将水质模拟问题转化为数学统计问题, 充分利用水质水体、沉积物监测数据, 采用克里格插值法对污染物浓度和水深在局部海域内进行插值, 将研究区域离散为一个个的均匀栅格单元, 比较每个单元污染物浓度与水质目标之间的差值, 从而估算得到研究海域的剩余环境容量。通过2009 年8 月锦州湾剩余环境容量的计算实例表明, 基于GIS 的剩余环境容量初步计算方法在资料缺乏地区是十分简便、有效的, 这为海域开发利用区环境管理与规划提供了参考。 |

| Abstract: |
| By now the water environment capacity was predicted and calculated based on pollution diffusion and the attenuation mechanism by means of the multi-dimensional water quality equation, which requires huge amounts of men and material input to conduct huge amounts of indoor stimulations and monitoring experiments and then obtains the required parameters of the model. However, the pollution mechanism is a very complicated process and the variations of parameters are inconsistent, so the results obtained by the traditional method of calculating water environment capacity are not entirely satisfactory. This paper explores a new method of water environmental capacity calculation based on Kriging method, through the pollutant concentration and depth discrete interpolation to determine the capacity of the water environment in the study area. By August 2009, Jinzhou Bay calculation examples show that in the area lack of information, the water environmental capacity preliminary calculation method based on GIS is very simple and effective, which provides a calculation way to control the water environmental pollution. |
