Contaminated site database 3D model display system

Abstract

The invention discloses a 3D model display system for a polluted site database, which includes a user management system, a database building system, a geographical vector data management application system, a data update system, a three-dimensional geological simulation system, a 3D model and demonstration system for spatial expansion of pollutants, 3D software and database interface and vector map and database interface. The invention can intuitively and clearly reflect the spatial variability and spatial distribution of site pollutants in a dynamic form, and provides scientific management means for the supervision and tracking of polluted sites.

Description

technical field [0001] The invention relates to the technical field of 3D model display, in particular to a 3D model display system for a polluted site database based on the control and tracking of polluted sites. Background technique [0002] With the transformation of my country's economic structure and the development of urban construction, a large number of industrial sites that have stopped production and relocated are facing land re-development and utilization, and site pollution will have a potential impact on human health. Environmental restoration of polluted sites is a necessary measure to protect human health and safety, and site pollution has become one of the most concerned environmental issues in my country. From April 2005 to December 2013, the Ministry of Environmental Protection and the Ministry of Land and Resources carried out the first national survey on soil pollution. Inorganic type is the main type, and the number of points exceeding the standard of i...

Problems solved by technology

At present, the definition of the spatial distribution range of pollutants in polluted sites is mostly based on a 2D plane, using the surface layer of the site or the soil drilling sample data of a single stratum, using geostatistical models or deterministic interpolation models for spatial distribution prediction and pollution mapping. For the definition of the spatial distribution of pollution in a single stratum, good prediction results can be achieved, but the characteristics of pollutant migration between different strata are not considered in the process of defining the pollution range of the entire site. With a certain degree of uncertainty, the accumulation of errors between different strata leads to errors in the determination of the final pollution range and the calculation of polluted earth volume.
