Method and system for determining safe distance between resident residence and mining area

Abstract

The invention relates to a method and a system for determining a safe distance between a resident residence and a mining area. The method comprises the steps of performing data cleaning on multi-source data; determining cancer death rates in different sample points; performing spatial empirical Bayesian smoothing on the cancer death rates in different sample points; performing global spatial autocorrelation analysis on the death rates of cancers in different sample points after spatial empirical Bayesian smoothing processing; when the spatial autocorrelation is represented as aggregation, performing interpolation analysis on the cancer death rate after spatial empirical Bayesian smoothing processing by using a spatial interpolation method; performing buffer area analysis on all sample points in the research area, and calculating the relative risk degree of cancer death at different distances according to the cancer death rate in the buffer area and the cancer death rate outside the buffer area; and determining the safety distance between the resident residence and the research area according to the relative risk degree. The invention can determine the safety distance between the resident residence and the mining area according to the space distribution rule of the lung cancer around the mining area.

Description

technical field [0001] The invention belongs to the interdisciplinary fields of spatial information science, geographic science, environmental science and medicine, and relates to spatial analysis technology, spatial interpolation analysis method and smoothing technology, medical spatial statistics technology, comprehensive data processing technology, etc. A method and system for determining a safe distance in a mining area. Background technique [0002] With the development of social economy, mineral resources have been continuously developed, and while people's living standards have been gradually improved, it has also brought many environmental problems. As natural constituents of the Earth's crust, heavy metals usually exist in nature in relatively low concentrations. However, due to frequent mining activities, the concentration of heavy metals in the environment has gradually increased, and heavy metal pollution around mining areas has become a serious global environme...
