Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0023] The implementation of the present invention is based on a geographic information system (GIS). Taking the Ningzhen Mountains as an example, the data sources include topographic information, hydrogeological drilling and hydrogeological maps, and groundwater dynamic monitoring data. Topographic information includes DEM and Tin; hydrogeological drilling and hydrogeological maps include hydrogeological drilling, hydrogeological maps and hydrogeological profiles; groundwater dynamic monitoring data are groundwater level monitoring points. Among them, DEM and Tin are interpolated by 1:50000 basic geographic information elevation data, DEM resolution is 50m; hydrogeological drilling data is hydrogeological drilling; hydrogeological map is integrated with hydrogeological map space data of 1:50000 bedrock geological map Attributes are obtained;...

Abstract

The invention discloses a proper water supply position intelligent recognition technology based on multi-source hydrogeology survey information. The intelligent recognition technology establishes an analytic hierarchy model (quantitative analysis model) by taking hydro-geological drilling, a plane hydro-geological map, a hydro-geological profile map, underground water dynamic monitoring data and the like as data sources, and taking a geography, a water bearing ground, a reservoir structure, an underground water level, an underground water flow direction, an underground water quantity, water quality and the like as recognition factors; the recognition factor information about the water supply survey hydrogeology on various hydrogeology survey spatial maps is automatically extracted by integrating the geographic information system (GIS) of the analytic hierarchy model, using a computer technology and the spatial analysis function of the GIS and combining expert knowledge, and a districtsuitable for water supply is rapidly evaluated and recognized according to a weight and a water-rich degree evaluation index endowed by each recognition factor so as to avoid the disadvantage of randomness of qualitative and empirical analysis site selection.

Description

technical field [0001] The invention relates to an intelligent identification technology based on multi-source hydrogeological survey information, which can determine a suitable water supply position in a water storage structure that meets the water supply demand, and belongs to the technical fields of earth observation and navigation technology and groundwater supply survey. Background technique [0002] There are many factors affecting groundwater supply surveys, and it is often necessary to comprehensively analyze multi-source data such as hydrogeological drilling, geophysical prospecting, and groundwater dynamics to determine the location and mining horizon of water supply projects. The traditional analysis methods are mostly qualitative and empirical analysis methods, which are more random. "Digital water conservancy" is an inevitable trend in the development of my country's water conservancy administrative management methods, and the scientific development and utilizat...
