摘要
基于湛江市地下水资源量估算影响因子分析,收集各影响因子数据,进行标准化处理;依据皮尔逊相关系数对各因子筛选,降低估算效率.并利用信息量法衡量各影响因子对地下水资源量估算的贡献率,叠加获取总信息量值确定地下水资源量等级,输出对应等级的地下水资源量估算结果.结果表明,估算结果RMSE值较低,其结果与实际地下水资源量基本一致性,具较高的估算效率.
Abstract
Based on the analysis of the influencing factors of the estimation of underground water resources in Zhanjiang City,the factors are screened according to the Pearson correlation coefficient to reduce the estimation efficiency.The information method is used to measure the contribution rate of each influencing factor to the estimation of underground water resources,and the total information value is superimposed to determine the level of underground water resources,and the estimation results of the corresponding level of underground water resources are output.The results show that the RMSE value of the estimation results is low,and the results are basically consistent with the actual underground water resources,and the estimation efficiency is high.
