摘要
地理信息测绘方法进行数据采集时存在相位噪声,导致测绘结果产生误差,对此,研究自然资源污染范围地理信息的测绘方法。归一化处理最大衰减矩阵,定义连续矩阵中的资源污染相邻位置,对资源污染范围的检测路径进行绘制;简化分析自然资源的污染程度,建设线性规律耦合动力模型,对污染范围中的资源不动点进行标记;以不动点作为资源划定常数,通过构建相位补偿函数,对应测绘基线的误差进行校正,测绘污染范围的地理信息,完成方法设计。实验结果表明,文章方法能够完成多种重金属污染指数的跟踪,且数据误差较小,具有一定的应用效果。
The phase noise exists in the data acquisition of geographic information mapping method,which leads to errors in the mapping results.Therefore,the mapping method of geographic information in the polluted area of natural resources is studied.This study normalized the maximum attenuation matrix,defined the adjacent positions of resource pollution in the continuous matrix,and plotted the detection path of the resource pollution range.It analyzed the pollution degree of natural resources,built a linear law coupling dynamic model,and marked the fixed points of resources in the pollution range.The fixed point is taken as the resource delimitation constant,and the method design is completed by constructing the phase compensation function,correcting the error of the mapping baseline,mapping the geographic information of the pollution range.The experimental results show that this method can complete the tracking of multiple heavy metal pollution indexes.The data error is small,so it has a certain application effect.
