General analysis of correlation between main areas of malignant tumor and environmental pollution

According to the third sampling investigation report on the cause of malignant tumor death, a spatial statistical analysis was done around the environmental pollution factors causing malignant tumor in China. This research was based on spatial statistics and Kriging interpolation tools, together with spatial variation models to construct the distribution of the death rate of malignant tumor, and the related environmental pollution models. The results showed that, the distribution of the death rate of malignant tumor is descending from the east to the west, and forming cluster characteristic in some areas. Through the spatial statistical distribution map, it is easily to observe the distributions of disease and its environmental pollution factors, thus can be used to analysis the characteristic of spatial distribution of malignant tumor quantitatively, which is also helpful to explain the popularity trend of disease geographically, to study the disease pathogenesis and to formulate regional preventing measures.
