Abstract:The comprehensive results analysis application system of national groundwater monitoring project is based on the eight unifified development softwares initially designed by the national groundwater monitoring project (water conservancy part). It fully takes into account the groundwater daily management analysis needs to develop comprehensive groundwater results analysis application systems for the business management staff of the Ministry of Water Resources. Based on the construction results of the 10298 automatic groundwater monitoring stations constructed this time, according to the relationship of supply, runoff, and drainage, seven types of data resources such as meteorology, hydrology, and water resources are integrated horizontally, and data of 17 provinces in the north from 2000 to 2016 are vertically integrated. The results of groundwater depth monitoring have realized functions such as deep processing of groundwater monitoring data, automatic generation of groundwater analysis and evaluation products, and rolling early warning of groundwater levels in groundwater overdraft areas. It provides important technical support for understanding the dynamic changes of groundwater in the main plains of the country, and clarifying the formation of groundwater overdraft areas process, status quo, and future trends, and the implementing of comprehensive management measures for groundwater over-exploitation in North China.
