摘要
为深入研究水体污染预测系统,更好地模拟二维空间上的水污染分布,将克里金法引入二维水质模型,考虑了空间属性在不同空间位置上的变异分布,使预测模型更合乎实际,功能更全面,并实现预测过程、结果的可视化。在GIS平台上运用数据库方法,将模型预测结果和Geodatabase数据类型进行链接与转换,力求形象直观地展现天然水体的污染分布情况。
To research the water pollution forecast system further,and simulate water pollution distribution of the two-dimensional space,the paper introduces kriging method into the two-dimensional water quality model,considering the variation distribution of space attribution in different space position,makes the model more realistic and comprehensive,in addition,realizes the prediction process and results visible.Using database method in the GIS platform,puts the prediction results and geodatabase data types link and transfer,in order to show the pollution distribution of natural water body visually.
