| Abstract: | Trend surface analysis is the widely used in mathematical geology,and it is used in studying the physical properties of the spatial distribution of the region of interest.It is a kind of multivariate statistical analysis method.This article describes the principle of trend surface analysis(according to its characteristics,using the least square method to solve the overdetermined problems).Based on thetheoretical numerical model,studied the trend surface analysis which used in the geophysical exploration.The results show that trend surface analysis can work as a smoothing filter in the geophysical exploration and eliminate the background field to highlight the anomaly. |

| Keywords: | trend surface analysis numerical model least square method overdetermined problem smoothing filter the value of background field |
