采用网格序列法的地下水漏斗可视化研究

Research on Visualization of Groundwater Depression Based on Grid Series Method

为了实时反映地下水水位分布状况,揭示地下水漏斗演变规律,采用网格序列法研究了地下水漏斗可视化模型。首先将研究区域划分成网格,其次使用改进的距离加权平均法对网格交点进行插值,最后根据视图原理计算产生地下水漏斗的各种视图。运用该方法对某平原区域1995年6月份的74眼观测井的水位数据资料进行了可视化处理,得到了符合实际的结果。

To reflect the distribution of groundwater level timely and explore the evolution laws of groundwater depression, the visual scheme on groundwater depression is studied using grid series method. Firstly, the research region is divided into grid. Secondly, intersecting points on grid is interpolated by using the improved method of distance-weighted mean. Finally, various view of groundwater depression is generated by calculating on the principle of views. Application result of this scheme is true of the practice for water level data of 74 observation-wells in June 1995 at a plain region.
